raycast to determine height of terrain

0 votes

Hey, I am trying to get the height of my terrain at a given X,Z point. Below is my code. I know the terrain has the correct collisionshape since I am able to walk on it correctly, but when I raycast down onto it to get the Y height I'm getting incorrect numbers (usually all below 1) which causes the below code to put trees inside the hills on my terrain. Am I using the raycast incorrectly? 

if(can_generate_tree):
        self.translation = Vector3(x, 1000, z)
        if($TreeCaster.is_enabled() && $TreeCaster.is_colliding()):
                var colliding_object = $TreeCaster.get_collider()
                if(colliding_object.get_name() == "TerrianStaticBody"):
                    if($TreeCaster.get_collision_point().y > max_y_of_treeline):
                        can_generate_tree = false
                    else:
                        y_pos = $TreeCaster.get_collision_point().y
                else:
                    can_generate_tree = false
        else:
            can_generate_tree = false

Where I get the Y pos is:

y_pos = $TreeCaster.get_collision_point().y

Maybe it would help if you uploaded the project so that we can see where the problem is originating.
