FProceduralMapGroup

Overview

FProceduralMapGroup is used to organize procedural maps into logical groups. It includes properties for the group's name and an array of soft object pointers to UProceduralMapParameters.

Properties

Type	Name	Access	Description
FName	GroupName	EditDefaultsOnly, BlueprintReadOnly	The name of the map group.
TArray<TSoftObjectPtr< UProceduralMapParameters >>	GroupMaps	EditDefaultsOnly, BlueprintReadOnly	An array of soft object pointers to `UProceduralMapParameters` representing the maps in this group.

Functions

Return Type	Signature	Description
bool	operator==(const FName& InGroupName) const	Compares the group name with another `FName`.

ALimenProceduralMapBuilder

Overview

ALimenProceduralMapBuilder is an abstract class that extends ALimenGameplayManager. It manages the lifecycle of procedural maps, handling events such as map load, build, destroy, and unload. The class uses delegates to notify when these events occur.

Properties

Type	Name	Access	Description
TArray	MapCollections	EditDefaultsOnly	An array of `FProceduralMapGroup` representing the collections of procedural maps.

Functions

Return Type	Signature	Description
FGuid	LoadMap(const FName GroupName, const int32 Index)	Loads a map from a specified group and index, returning a unique identifier for the map.
void	BuildMap(const FGuid& MapId)	Initiates the building process for a map identified by `MapId`.
void	DestroyMap(const FGuid& MapId)	Initiates the destruction process for a map identified by `MapId`.
void	UnloadMap(const FGuid& MapId)	Initiates the unloading process for a map identified by `MapId`.
bool	IsMapLoaded(const FGuid& MapId) const	Checks if a map is currently loaded.
bool	IsMapBuilt(const FGuid& MapId) const	Checks if a map has been built.
bool	DoesMapExist(const FName GroupName, const int32 Index) const	Checks if a map exists in the specified group and index.
int32	GetCollectionMapCount(const FName& CollectionName) const	Returns the number of maps in a specified collection.
TArray<TWeakObjectPtr< ULimenProceduralMap >>	GetLoadedMapsData() const	Retrieves an array of weak object pointers to loaded procedural maps.
TArray<TWeakObjectPtr< ULimenProceduralMap >>	GetBuiltMapsData() const	Retrieves an array of weak object pointers to built procedural maps.
int32	GetMapsBuilt() const	Returns the total number of maps that have been built.
FOnMapUpdate&	GetOnMapBeginBuild()	Gets the delegate for when a map begins building.
FOnMapUpdate&	GetOnMapFinishBuild()	Gets the delegate for when a map finishes building.
FOnMapUpdate&	GetOnMapBeginLoad()	Gets the delegate for when a map begins loading.
FOnMapUpdate&	GetOnMapFinishLoad()	Gets the delegate for when a map finishes loading.
FOnMapUpdate&	GetOnMapBeginUnload()	Gets the delegate for when a map begins unloading.
FOnMapUpdate&	GetOnMapFinishUnload()	Gets the delegate for when a map finishes unloading.
FOnMapUpdate&	GetOnMapBeginDestroy()	Gets the delegate for when a map begins destroying.
FOnMapUpdate&	GetOnMapFinishDestroy()	Gets the delegate for when a map finishes destroying.

Usage & Implementation Notes

The class uses TFunction to define callbacks for asynchronous operations like building and destroying maps.
It manages map instances using a TMap, where each entry is identified by a unique FGuid.
The class includes delegates (FOnMapUpdate) that can be used to notify other parts of the system about significant events in the lifecycle of procedural maps.
