Issues with raycast and collisions.

[silk ravine]

is there a specific reason as to why you are not using collisions?

Changing position does not update the physics state. You have to use the designated methods like move_and_collide() or move_and_slide()

And preferably run them on _physics_process()

After ray.Rotation try to run force_raycast_update()

Sorry forgot to say I fixed it!

Not efficient, but it works.
