Allow & document customisation of Player and Goober

[cassidyjames]

I gave this a try:

1. Copied the textures into my own world's folder and recolored them to purple
2. Copied the TileSet.tres into my own world's folder, renamed it to Purple.tres for clarity
3. In the TileSet bottom panel I selected each tile and set its texture to my recolored version
4. In each of my levels' TileMapLaer node, I set the Tile Set (in the Inspector panel) to my Purple.tscn

This worked, but only for the wall tiles; the others (player, goober, explosion) showed the correct tiles in the level designer, but still use the original tiles when playing the game.

This appears to be due to how the tilemap is used as a placeholder to be replaced by the "live" scenes, around here:

everlasting-candy/Script/Game.gd

Lines 54 to 75 in 6677267

	func MapStart():
	for pos in Map.get_used_cells():
	var id = Map.get_cell_source_id(pos)
	match id:
	TILE_WALL:
	# Use random wall tile from 3×3 tileset to make levels look less repetitive
	var atlas = Vector2(randi_range(0, 2), randi_range(0, 2))
	Map.set_cell(pos, TILE_WALL, atlas)
	TILE_PLAYER:
	# Add live player to the scene
	var inst = ScenePlayer.instantiate()
	inst.position = Map.map_to_local(pos) + Vector2(4, 0)
	self.add_child(inst)
	# Remove static player tile from the tile map
	Map.set_cell(pos, -1)
	TILE_GOOBER:
	# Add live goober to the scene
	var inst = SceneGoober.instantiate()
	inst.position = Map.map_to_local(pos) + Vector2(4, 1)
	NodeGoobers.add_child(inst)
	# Remove static goober tile from the tile map
	Map.set_cell(pos, -1)

@cassidyjames the alternative way to do it for the Gobbers or Player is to instantiate the scenes. You can duplicate the Player.tscn and Goober.tscn into your own world folder and customize these scenes. Then instantiate them instead of painting the tiles.
