Question

I have a CharacterBody2D with a RayCast as a child, and I want to have a function that sets the raycast’s target position to another global position and returns where it collides along the way. I’ve tried doing that with

func target_collision_point(target: Vector2) -> Vector2:
	self.target_position = self.global_position - target
	self.force_raycast_update()
	return self.get_collision_point()

but it doesn’t work and set it to a very far away position, not even in the correct direction.

try this:

target_position = to_local(target.global_position)

thanks that worked! how would I extend a ray cast in a specified direction (normalized vector) until it hits something?

You just set the distance as high as you want it to reach. It will automatically return the first collider it hits
