Is It in the Group?

Part of the Signals and Collisions section of Coddy's Godot journey. Lesson 12 of 27.

Checking body.name works for one node. For a set of nodes, check the group:

if body.is_in_group("racers"):
	print(body.name, " finished!")

is_in_group() is true or false. Use it even for one node. A name changes when you rename or copy a node. A group says what the node is.

Three robots run to the finish line. Red and Blue are in the group racers, set in the scene. Bot cleans the track and is in no group.

Challenge

Easy

Make the finish line print only for racers.

  1. In _on_body_entered(body), put the print inside an if.
  2. Make the if ask body.is_in_group("racers").

Press Play: the Console shows Red finished! and Blue finished!, and nothing for Bot. Then Check.

Try it yourself

func _ready():
	body_entered.connect(_on_body_entered)

func _on_body_entered(body):
	print(body.name, " finished!")
