How to use set_defered() in GODOT

Every time an enemy hits a player, a signal will be given. We need to disable the player's collection so that we don't trigger the hit signal more than once.

Note: Disabling the shape of the collision area may result in an error if it occurs in the middle of the collision processing by the engine. Using set_deferred() tells Godot to wait for the figure to be disabled until it is safe to do so.

GD script

func _on_body_entered(body):
    # Must be deferred as we can't change physics properties on a physics callback.
    $CollisionShape2D.set_deferred("disabled", true)

C#

private void OnBodyEntered(Node2D body)
{
    // Must be deferred as we can't change physics properties on a physics callback.
    GetNode("CollisionShape2D").SetDeferred(CollisionShape2D.PropertyName.Disabled, true);
}
