The slot’s save as bytes, on every platform. Import Rolly Slot from Bytes stores them again. Works on clients: it reads this machine’s storage.

Export Rolly Slot to File

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

Writes <File Name>.<Export Extension> in the export folder, on Windows, Mac and Linux. Fails with Name Collision when a file of that name is no Rolly Save file, which is never replaced. Works on clients.

Export Rolly Slot to JSON File

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

Writes the slot’s save as <File Name>.json in the export folder. Every build, desktop platforms. Works on clients.

Export Rolly Slot to JSON Text

Latent, from URollySaveJsonAction: it goes on from one of Success, Failure.

The slot’s save as JSON text, for your own bug reporter, on every platform; Invalid Data past Max JSON Import Size. Works on clients: it reads this machine’s storage.

Find Rolly Instance by Key

Pure and static, in URollySaveSubsystem.

The component and current index of the instance Key names. False when its component is not loaded or not tracked, when no instance has the key any more, such as after it was removed, and on a client.

Forget All Levels

On URollySaveSubsystem.

Forgets every level Rolly Save keeps, the player’s current level included, as Forget Level does. Unlike Clear Loaded Game, it keeps what Rolly Save holds outside levels, such as registered objects’ values, so New Game+ can reset the world and keep progress. Does nothing on a client or while a load runs.

Forget Level

On URollySaveSubsystem.

Forgets what Rolly Save keeps of Level (its actors, destroyed actors and Level Blueprint), so the next time travel opens it, it starts as designed. For the level the player is in, that is the visit after they leave it; a save made before then still holds it. Does nothing on a client or while a load runs.

Gather

An event of URollySaveHandler that a Blueprint child class implements.

Set this handler’s variables that have SaveGame ticked from the game, such as a sky actor’s time of day. Runs during each save, on the server or in a standalone game.

Get Current Slot

Pure, on URollySaveSubsystem.

The slot last saved or loaded by name, which Autosaves Write To and Checkpoints Write To can write instead of their own slots. Cleared by Clear Loaded Game, New Game+ and deleting that slot.

Get Game Time Seconds

An event of URollySaveGameClock that a Blueprint child class implements.

Return your game’s time in seconds, 0 or more, from a value that exists before any level loads, such as one in your Game Instance. Called when the player leaves a level, when it is built again, once by a save or a leave that holds harvested instances whose time was not read yet, once by a load that sets instances that regrow, and by Check Rolly Regrowth; never every frame.

Get Last Load Result

Pure, on URollySaveSubsystem.

The result of this game’s last load, from the moment its saved values are set, so Begin Play in the loaded map can read it. False before any load, after Clear Loaded Game, and in another subsystem’s Deinitialize after Rolly Save’s own.

Get Memory Slots

On URollySaveSubsystem.

Memory slots and rewind points, newest first.

Get New Game Plus Cycle

Pure, on URollySaveSubsystem.

0 in a first game; Start Rolly New Game Plus raises it by 1.

Get Play Time

Pure, on URollySaveSubsystem.

Play time since the new game: a whole-game load sets it from the save, Clear Loaded Game resets it, paused time does not count and slow motion counts at real speed.

Get Profile

Pure, on URollySaveSubsystem.

The profile once usable (Succeeded); else None with Busy or the load’s status.

Get Profile Key

An event of URollySavePlayerIdProvider that a Blueprint child class implements.

The key of the player’s profile, such as the account ID the platform signed in. Rolly Save files it as id_ and the key, made safe for every file system; any text of 1 to 1,024 characters works. Empty uses the platform user’s profile, with a setup warning. Asked once as each local player joins.

Get Rolly Instance Key

Pure and static, in URollySaveSubsystem.

The key of the instance at Instance Index of Component. It names the instance across saves and loads while the level’s design of it stays the same, unlike its index, which changes as other instances are removed; an instance your game added has one too. Keep your own data per instance under it, such as a tree’s wood left, in a map you save. False for a component Rolly Save does not track, an index outside it, and on a client.

Get Rolly Profile Key

Pure, on URollySaveSubsystem.

The key of the player’s profile, such as to show each profile its own saves in your menu. Empty while a named profile key is being found as the player joins, and when the profile could not load.

Get Save ID

Pure and static, in URollySaveSubsystem.

The ID a save stores Object under, for logs and your own records: /Game/Maps/Tavern:Chest_2 for an actor placed in a level, /Game/Maps/Tavern:#FrontDoor with a Custom Save ID, 32 hexadecimal digits for an actor spawned during play, which gets it the first time it is saved or asked for and keeps it after loads. False for objects Rolly Save never saves, such as a widget, and on clients.

Get Save Status Text

Pure and static, in URollySaveSubsystem.

A sentence for players about Status, for games without a slot screen of their own; empty for Succeeded.

Get Target Actor

Pure, on URollySaveHandler.

The actor this handler saves when a Save Rule or Rolly Save component attaches it; None for a Global Handler. Set during Gather and Apply.

Hold Rolly Player

On URollySaveSubsystem.

Holds Player as a load does: with Hold Method Stop Movement its pawn stands still and its move input is ignored, and a pawn it possesses while held is held in turn. With Until Ground, Rolly Save releases it once the ground under the pawn has loaded, or after Max Hold Time: call it right after your own teleport. Without, it stays held until Release Rolly Player with the same Reason. A hold ends when its controller goes or its world changes. False on a client, for a controller without a pawn, and with Until Ground when the ground has loaded already.

Import Engine Save Game

Latent, from URollySaveImportAction: it goes on from one of Success, Failure.

Reads a save that Save Game to Slot wrote, so you can copy its values into objects Rolly Save saves. Nothing is created unless the file holds Expected Class or a child of it. Never writes or deletes engine saves. Works on clients.

Import Rolly Slot from Bytes

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

As Import Rolly Slot from File, from bytes, on every platform. Bytes above Max Import Size are refused unread. Works on clients.

Import Rolly Slot from File

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

Checks <File Name>.<Export Extension> in the export folder as a save from another machine and stores it as a new slot, on Windows, Mac and Linux. Fails with Slot Exists when the slot holds a save: an import never overwrites. Works on clients.

Import Rolly Slot from JSON File

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

Checks <File Name>.json from the export folder and stores it as a new slot. Shipping and Test builds need JSON Import in Shipping. Fails with Slot Exists when the slot holds a save: an import never overwrites. Works on clients.

Is Marked for Reset

Pure, on URollySaveResetAreaComponent.

True from Mark Area for Reset until the reset happens.

Is Removed by Load

Pure and static, in URollySaveSubsystem.

True while a load removes Actor because the save holds it as destroyed. In a network game a replicated placed actor still runs Begin Play, End Play and Event Destroyed once before it goes, and a load with Keep Current Map runs End Play and Event Destroyed: check this there to skip what a destruction in play does, such as dropping loot. False on clients.

Is Restoring

Pure, on URollySaveSubsystem.

True while a load runs or Rolly Save sets saved values: a load, a level’s return, or the players’ values after a load. Rolly Save Triggers ignore entries then; check it in your own triggers too.

Is Rolly Game in Play

Pure, on URollySaveSubsystem.

True while a game is in play in the current map on the server or in a standalone game, which lifecycle saves need with Lifecycle Saves In at Game in Play. While Maps Without Autosave lists maps: in every map it does not list, unless Set Rolly Game in Play turned play off there. Without a list: after a whole-game load or save in this map, in the map opened after Clear Loaded Game or Start Rolly Run, after seamless travel or reopening the same map, or after Set Rolly Game in Play; the game’s change to another map ends it. Always false on a client, where no whole game loads.

Is Rolly Player Held

Pure, on URollySaveSubsystem.

True while Player has any hold: Rolly Save’s own after a load or travel, or one from Hold Rolly Player. False on a client.

Is Rolly Thumbnail Hold Set

Pure and static, in URollySaveThumbnailHoldLibrary.

True when Hold keeps a picture, or one on its way.

Is Rolly World Ready

Pure, on URollySaveSubsystem.

False from On Load Started until that load’s On World Ready, and while a player Rolly Save held after a travel waits for ground or its pawn; true otherwise, and always on a client.

Is Run Active

Pure, on URollySaveSubsystem.

The running game is a run, in this slot: other saves, memory slots and rewind are refused.

Is Save Blocked

Pure, on URollySaveSubsystem.

True while a save block is on, such as to grey out a Save button.

List Rolly Export Files

Latent, from URollySaveListAction: it goes on from one of Success, Failure.

Named profiles by name, read without opening their files.

List Rolly Slots

Latent, from URollySaveListAction: it goes on from one of Success, Failure.

Load Game Part from Rolly Slot

Latent, from URollySaveLoadAction: it goes on from one of Success, Failure.

Sets Scope’s values on the objects present now, as Keep Current Map does. A missing part is an Issues line MissingPart; all missing is Not Found. Runs on the server or in a standalone game.

Load Game from Rolly Memory Slot

Latent, from URollySaveLoadAction: it goes on from one of Success, Failure.

Loads a memory slot. Runs on the server or in a standalone game.

Load Game from Rolly Slot

Latent, from URollySaveLoadAction: it goes on from one of Success, Failure.

Loads a slot’s save. With Open Saved Map, the map the save was made in opens and every saved value is set before Begin Play; Success then runs only where the caller survives the map change, such as the Game Instance. Elsewhere, bind On Load Finished in Begin Play. Failures found before the map changes reach Failure. Runs on the server or in a standalone game.

Load Rolly Checkpoint

Latent, from URollySaveLoadAction: it goes on from one of Success, Failure.

Loads the newest checkpoint, memory first: the memory slot checkpoint when the session has one, so a retry reads no storage, else the slot Save Rolly Checkpoint writes in storage; during a run, the run’s slot. Runs on the server or in a standalone game.

Load Rolly Profile

Latent, from URollySaveProfileAction: it goes on from one of Success, Failure.

Gives the profile when ready: at once when it loaded, after its load otherwise, and read again after a load that failed. Success: Succeeded, or Not Found for a new player, whose profile holds defaults.

Load Rolly Slot Thumbnail

Latent, from URollySaveThumbnailAction: it goes on from one of Success, Failure.

The slot’s picture as a texture for your own menu. Failure with Not Found when it has none.

Mark All Areas for Reset

Static, in URollySaveSubsystem.

Marks every Reset Area of the current map, as Mark Area for Reset does. Does nothing on a client.

Mark Area for Reset

On URollySaveResetAreaComponent.

Its actors start as designed the next time its level is built: a return by travel, or a load of a save made after this call. To reset now, save with Save Game to Rolly Memory Slot and load that slot with Open Saved Map. Saved. Does nothing on a client.

Mark Slot Screen Request Handled

On URollySaveSubsystem.

Says your listener of On Slot Screen Requested, the subsystem’s or a Save Point’s, handled the request, such as by opening your own menu, so a Save Point on Automatic saves no checkpoint. Call it inside that listener, before it returns; outside one it marks nothing and reports MarkOutsideRequest.

On Area Reset

An event of URollySaveResetAreaComponent to bind.

It reset its actors as this level was built. Fires once the level’s actors have begun play, on the server or in a standalone game.

On Before Lifecycle Save

An event of URollySaveSubsystem to bind.

A lifecycle save is about to capture the game in this frame: the game goes to the background, quits, lost its window’s focus or its session ends. Copy what your game keeps outside saved variables into them here, or pause. No frame is drawn before the save. On the server or in a standalone game.

On Instances Regrown

An event of URollySaveSubsystem to bind.

Removed instances of Component came back as the level designs them, by Regrow After or because a Reset Area reset them. Instance Indices are their indices now and Keys their keys, in the same order, so you can reset your own data for them. When a level is being built, it fires once the level’s actors have begun play.

On Load Cancelled

An event of URollySaveSubsystem to bind.

The Cancel Load node, or Cancel on a load node’s Async Action pin, stopped a load before its map change: nothing of it was set, and neither its node’s pins nor On Load Finished fire. A loading screen shown since On Load Started closes here.

On Load Finished

An event of URollySaveSubsystem to bind.

A load ended. After Open Saved Map it fires in the loaded map after every actor’s Begin Play, so bind it in Begin Play; the Game Instance’s Event Init runs before Rolly Save starts.

On Load Progress

An event of URollySaveSubsystem to bind.

An event of URollySaveSubsystem to bind.

A load started; Opens Map is true when it travels to the saved map.

On Loaded

An event of URollySaveComponent to bind.

The actor and every other object of the same load, or of its level’s return, have their saved values, so references between them are set. Runs after the actor’s own On Rolly Save Loaded.

On Low Storage

An event of URollySaveSubsystem to bind.

The storage had less free space than Project Settings’ Low Storage Warning after a save. Fires once, and again only after the free space rose above it. Never on storage that keeps each user’s saves apart, which cannot be measured.

On Player Held

An event of URollySaveSubsystem to bind.

Player’s first hold started: with Hold Method Stop Movement its pawn stands still and its move input is ignored until On Player Released.

On Player Released

An event of URollySaveSubsystem to bind.

Player’s last hold ended and it moves again. Timed Out is true when Max Hold Time ended a hold that waited for ground.

On Pre Save

An event of URollySaveComponent to bind.

The actor is about to be saved, or remembered as the player leaves its level. Copy state that is not in a variable with SaveGame ticked into one here.

On Profile Loaded

An event of URollySaveSubsystem to bind.

A profile load ended, the one at a local player’s start included; Result’s Slot Name is the profile key.

On Profile Saved

An event of URollySaveSubsystem to bind.

A profile save ended, also one made with a game save; Result’s Slot Name is the profile key.

On Rolly Save Loaded

An event of URollySaveInterface that a Blueprint child class implements.

Runs once this object and every other object of the same load, or of its level’s return, have their saved values, so references between them are set. Rebuild what depends on saved values here.

On Rolly Save Pre Save

An event of URollySaveInterface that a Blueprint child class implements.

Runs right before this object is saved, and before its level is remembered as the player leaves it. Copy state that is not in a variable with SaveGame ticked into one here.

On Rolly Save Saved

An event of URollySaveInterface that a Blueprint child class implements.

Runs once a save that holds this object is written; not after a failed save, and not when its level is only remembered.

On Save Changed Outside Game

An event of URollySaveSubsystem to bind.

A load found the newest copy of the save changed outside the game (Project Settings > Protection), before On Load Finished. With Changed Saves = Load and Report it loaded anyway, so a game can flag the player; otherwise its backup loaded, or nothing did. Nothing of the save is set yet, so Cancel Load here stops the load. On the server or in a standalone game.

On Save Finished

An event of URollySaveSubsystem to bind.

A save ended, whether a node, C++ or the quick save key asked for it; Status says how. Fires on the server or in a standalone game.

On Save Finished

An event of URollySaveTriggerComponent to bind.

The save its action made ended: Save Checkpoint, Save to Slot, Automatic’s checkpoint, and an autosave once written. Not for an autosave that Minimum Gap, Maps Without Autosave or Stop Autosave dropped.

On Save Started

An event of URollySaveSubsystem to bind.

A save started its capture, on the server or in a standalone game, with who started it; On Save Finished follows for each, also for an autosave dropped by a load before its write. A save asked for from here is refused with Busy.

On Saved

An event of URollySaveComponent to bind.

A save holding the actor was written. Not after a failed save, and not when its level is only remembered.

On Saved Values Applied

An event of URollySaveSubsystem to bind.

On Slot Screen Requested

An event of URollySaveSubsystem to bind.

A slot screen was asked for a local player. Rolly Save’s slot screen listens here; bind it to open your own menu instead, and call Mark Slot Screen Request Handled in your listener so the request counts as handled.

On Slot Screen Requested

An event of URollySaveTriggerComponent to bind.

Its action asked for the slot screen for Player, whether or not anything opened it. For a local player it fires inside the request, after the Rolly Save Subsystem’s On Slot Screen Requested: bind it to open your own menu, and call Mark Slot Screen Request Handled in it so Automatic does not also save a checkpoint.

On State Changed

An event of URollySaveTriggerComponent to bind.

Enabled or Triggered changed, on the server and, when its actor replicates, on clients. Set up looks from them in Begin Play too, since a load sets them before.

On Streamed Level Ready

An event of URollySaveSubsystem to bind.

Rolly Save is done with a streaming level, level instance or World Partition cell that became visible: its saved values are set, its spawned actors are back and its Reset Areas ran. Restored is true when Rolly Save holds state for it, set now or kept since its unload; false when nothing is saved for it. Levels present when the map’s actors initialize are set with the map’s load, which On Load Finished reports.

On Triggered

An event of URollySaveTriggerComponent to bind.

It triggered, right before its action, so Set Slot Location and Set Slot Game Fields called here reach this save. On the server or in a standalone game.

On User Signed In

An event of URollySaveSubsystem to bind.

A platform user signed in, on platforms that keep each user’s saves apart, such as consoles: the player’s profile loads again.

On User Signed Out

An event of URollySaveSubsystem to bind.

A platform user signed out, on platforms that keep each user’s saves apart: the player’s profile went, unsaved. With Saving User, the user owned the slots, so saving them is paused (Project Settings > When the Saving User Changes); follow the platform’s rules from here, such as returning to the title screen.

On World Ready

An event of URollySaveSubsystem to bind.

The world a load set up is ready to play: On Load Finished fired, each player Rolly Save held for it stands on loaded ground, a player whose pawn came later has it (within Max Hold Time), and spread After Begin Play values are set. After a failed load it fires right after On Load Finished; a load followed by another load or a travel before then gets none. With Hold Players After Loads and Travel it also fires when the last player held after a travel is released, with an empty Slot Name.

Rearm

On URollySaveTriggerComponent.

Lets it trigger again after Once or Once per Visit, and ends Cooldown. Saved. Does nothing on a client.

Register Object for Saving

On URollySaveSubsystem.

Saves Object under Name: its variables with SaveGame ticked go into every save, and after a load they are set when an object registers under Name. For objects Rolly Save does not save on its own, such as a quest manager. Names compare with capital letters. False, with a setup message, when Name is taken, Object already saves or Group cannot be a group’s name; false after the game instance ended, which another subsystem’s Deinitialize may meet.

Release Held Rolly Players

Static, in URollySaveThumbnailHoldLibrary.

When the next save would hold Hold’s picture because Use Rolly Thumbnail Hold gave it and no save took it, such as after the menu’s save failed, it no longer does. Another held picture stays. Call it when the menu closes without saving.

Reload Save Rules

Latent, from URollySaveReloadRulesAction: it goes on from one of Completed.

Rename Rolly Slot

Latent, from URollySaveSlotAction: it goes on from one of Success, Failure.

Request Autosave

On URollySaveSubsystem.

Autosaves now, unless within Minimum Gap of the last save to storage, after Stop Autosave or in a map without autosave; then the log says it was dropped. During a load, seamless travel or a save block it waits.

Request Slot Screen

On URollySaveSubsystem.

Asks the slot screen to open for Player, through On Slot Screen Requested. True when a listener handled it: one that called Mark Slot Screen Request Handled, as Rolly Save’s slot screen does when it opens, or any listener with Slot Screen Requests Need a Mark off.

Loads that profile for the player and remembers the choice. Saves nothing by itself.

Use Rolly Thumbnail Hold

Static, in URollySaveThumbnailHoldLibrary.

Wait for Rolly World Ready

Latent, from URollySaveWaitWorldReadyAction: it goes on from one of Ready.

Continues at Ready on a later tick than the call: at once when Is Rolly World Ready is true, otherwise at On World Ready, or on the tick after a travel ended the wait without it, once the new world is ready; a node whose world went ends without Ready. Use it in Begin Play of actors that should start only on loaded ground, such as AI or your own fade-in. On a client it continues at once.

Rolly|Save|Migration

Fail Migration

On URollySaveMigrationContext.

Stops the load with Migration Failed; Detail holds Reason.

Find Records by Class

On URollySaveMigrationContext.

Records whose class is Class Path, compared after Core Redirects.

Find Records by Subject

On URollySaveMigrationContext.

The record saved for that object, such as Global and GameMode.

Get File Version

Pure, on URollySaveMigrationContext.

The save’s Game Data Version before this run’s steps.

Get Path Value

On URollySaveMigrationContext.

Reads a value saved by path into the connected variable, as Get Saved Value reads a saved value. False, leaving the variable as it was, when absent or saved as another type. Use it with Set Path Value to keep the player’s value when the property’s type changes, such as a float that became a double.

Get Path Value Type

Pure, on URollySaveMigrationContext.

The saved type’s name of a value saved by path, such as FloatProperty; empty when absent. Name is the property, then each member inside it, joined by a dot, such as Intensity or BodyInstance.CollisionEnabled.

Get Record Info

Pure, on URollySaveMigrationContext.

Where the record is and what it was saved for.

Get Saved Value

On URollySaveMigrationContext.

Reads the value into the connected variable. False, leaving the variable as it was, when absent, saved as another type (connect a variable of the saved type), or holding what a step cannot read: a pointer to another saved object, to an object the saved object owns or to an asset or class that is not loaded, or a text from a string table that is not loaded. Steps run before the save’s objects and assets load, so rename or remove such a value instead of writing it back.

Get Saved Value Names

Pure, on URollySaveMigrationContext.

Its top-level saved values.

Get Saved Value Type

Pure, on URollySaveMigrationContext.

The saved type’s name, such as IntProperty or StructProperty(Vector(/Script/CoreUObject)); empty when absent.

Get Slot Name

Pure, on URollySaveMigrationContext.

The name of the slot the save loads from.

Migrate

An event of URollySaveMigrationStep that a Blueprint child class implements.

Change the save’s records: find them through Context, read and write their saved values, or call Fail Migration to refuse the save. Runs before anything of the save loads.

Remove Path Value

On URollySaveMigrationContext.

Removes a value saved by path. False when the record holds none of that name.

Remove Record

On URollySaveMigrationContext.

Removes the record from the save.

Remove Saved Value

On URollySaveMigrationContext.

False when the record holds no value of that name.

Rename Record Subject

On URollySaveMigrationContext.

Renames the object it was saved for and every saved reference to it. False when another record is saved for New Subject.

Rename Saved Value

On URollySaveMigrationContext.

False when New Name exists or Old Name does not.

Set Path Value

On URollySaveMigrationContext.

Writes the value with the connected type as a value saved by path, adding it when absent. A load gives it back only while a Save Rule or Rolly Save component picks it and its type is the property’s. False when the record would pass a limit.

Set Record Class

On URollySaveMigrationContext.

The record applies to objects of Class Path, such as /Game/Chests/BP_Chest.BP_Chest_C.

Set Saved Value

On URollySaveMigrationContext.
