Only the Player

Part of the Signals and Collisions section of Coddy's Godot journey. Lesson 4 of 27.

An area notices every body that comes in. Often only one should count, like a door that opens only for the hero.

Use if to check who it is:

func _on_body_entered(body):
	if body.name == "Player":
		print("Hello, player")

== asks whether two values are equal. The lines under the if, one tab further in, run only when they are. Names must match exactly. "player" with a small p is a different name.

Here the rover rolls over a pressure plate first, then you walk onto it.

Challenge

Easy

Make the plate react only to the player.

In _on_body_entered(body), put the modulate line inside an if.
Make the if ask whether body.name is "Player", with ==.

Press Play: the plate keeps its color for the rover and turns mint when you step on it. Then Check.

Try it yourself

extends Area2D

func _ready():
	body_entered.connect(_on_body_entered)

func _on_body_entered(body):
	modulate = Color(0.49, 0.95, 0.75)
