The RayCast is a child of the Camera node and is pointing into the same direction of the camera in the editor. Why not use Camera. The term you’re looking for is bullet tracing and I’m only sure of how to do this in 2d but you should start with getting the point your ray collides with and also use the point at the end of the barrel of the gun I believe the way to do it is if is_colliding: collider.

Goal: The player can select the tile that the camera is hovering over. get_collision_point() So I tell raycast to only collide with the level geometry, I move raycast into the same positions as specified above, and get it's collision point. I’ve made a quick prototype script in GDScript to sort things out since I’m new I have tried this previously , just put this script on a camera and read the position of the clickpos variable and it should work and make sure whatever mesh you are using it should have a static body child or parent , and a collision mesh, because you need colliders to make it work.

Inherits: Node3D< Node< Object A 3D raycast that dynamically moves its children near the collision point. mousePosition). I recently ran into an issue where my game captures the mouse, which means that these areas no longer detect input If the raycast and the physics body are on the same collision layer the raycast will just immediately return whatever it's inside, that's why there's a setting for excluding the parent. For simple raycasts, node such as RayCast and RayCast2D will work, as they will return every frame what the result of a raycast is the Camera node is needed. I just saw 'change the collision shape to be inside out', this can only be done with a trimesh collision shape because to Godot it's hallow. Description¶. Like offlimit of the map.
