Automating Camera limits (i.e. making it not able to go past tilemap )

SilverPlatinum

Just a short question this time. How would you make the camera limits the same as the tilemaps? (Like the camera cannot go past the tilemap?)

edit: alright this is the code I have for the boundaries so far

func _ready():
	var tilemap_rect = get_parent().get_node("TileMap").get_used_rect()
	var tilemap_cell_size = get_parent().get_node("TileMap").cell_size
	$Camera2D.limit_left = tilemap_rect.position.x * tilemap_cell_size.x
	$Camera2D.limit_right = tilemap_rect.end.x * tilemap_cell_size.x
	$Camera2D.limit_top = tilemap_rect.position.y * tilemap_cell_size.y 
	$Camera2D.limit_bottom = tilemap_rect.end.y * tilemap_cell_size.y
	pass

and it seems to work for now, so I will mark this question as answered. Thank you everyone ( I found a tutorial for this )

if you have one tilemap per level. you can add that tilemap into group, "geometry" for example, and in the camera-node you have somethin like:

# camera.gd
func _ready():
	var tilemap : TileMap = get_nodes_in_group("geometry")[0]  # get fisrt item in geometry group
	var rect : Rect = tilemap.get_used_rect()
	limit_left = rect.x
	limit_right = rect.x + rect.size.x
	limit_top = rect.y
	limit_bottom = rect.y + rect.size.y

It says “get_nodes_in_group” isn’t declared in current class.

Would I have to say get_tree first?

I found a tutorial and fixed it.
