Grid Tool for UE5 example

UE5 GridTool

Grid tool is an actor, that contains editable slots every 1 meter in X, Y and Z axis. In editor user can set which class should be spawned at any given slot upon game start.

Classes

Project contains several C++ classes which include

• LevelChunk (Base class for grid tool actor)
• LevelGridSlot (Base for a single slot)
• SpawnableElement (Base for any object that can be spawned in slot)

Only classes that inherit from SpawnableElement can be picked as an object in Slot component

Some of those classes have their base Blueprint implementations in /Content/Blueprints/ directory

Optimizations

• Slots hold TSoftClassPtr pointers instead of a UClass. Classes get loaded when previewing, and/or on BeginPlay. One can add implementation to manually decide when to load classes. Currently classes are loaded synchronously, but async implementation can be added.
• All LevelChunk components (slots and previews) get destroyed upon game start.

Settings

User can define grid size in every dimension (X, Y, Z).

Previewing

• To preview all slots in currently selected BP_LevelChunk, press the "PreviewElements" button located in ActorMethods category in the Details panel.
• To hide previews hit the "HidePreview" button located in the same panel.

Selecting

To select a single slot when the whole actor is selected double click chosen slot in the viewport.
