Chunk_AddEndTrigger()

void Chunk_AddEndTrigger	(	Vec2	startTile,
		Vec2	endTile,
		EnvironmentChunk *	chunk
	)

[Utility] Adds an end room trigger collider to a chunk

Adds an end trigger to a chunk.

Creates a trigger zone in the center of the end room that detects when the player has reached the level exit.

Parameters

startTile	Starting tile position
endTile	Ending tile position
chunk	Pointer to the chunk

Chunk_AddHallwayTrigger()

void Chunk_AddHallwayTrigger	(	Vec2	startTile,
		Vec2	endTile,
		EnvironmentChunk *	chunk
	)

[Utility] Adds a hallway trigger collider to a chunk

Adds a hallway trigger to a chunk.

Creates a trigger zone that detects when the player is inside a hallway.

Parameters

startTile	Starting tile position
endTile	Ending tile position
chunk	Pointer to the chunk

Chunk_AddRoomTrigger()

void Chunk_AddRoomTrigger	(	Vec2	startTile,
		Vec2	endTile,
		EnvironmentChunk *	chunk
	)

[Utility] Adds a room trigger collider to a chunk

Creates a trigger zone that detects when the player is inside a room.

Parameters

startTile	Starting tile position
endTile	Ending tile position
chunk	Pointer to the chunk

Chunk_AddWallCollider()

void Chunk_AddWallCollider	(	Vec2	startTile,
		Vec2	endTile,
		EnvironmentChunk *	chunk
	)

[Utility] Adds a wall collider to a chunk
