Help with raycasting in 4.1.3 C#

TsenoTsenov

Hi,

I'm trying to raycast and have the following function:

`public override void _Process(double delta)
{
PhysicsDirectSpaceState3D space_state = GetWorld3D().DirectSpaceState;
Vector2 mouse_position = GetViewport().GetMousePosition();
Camera3D camera = GetTree().Root.GetCamera3D();
Vector3 ray_origin = camera.ProjectRayOrigin(mouse_position);
Vector3 ray_end = ray_origin + camera.ProjectRayNormal(mouse_position) * 2000;
PhysicsRayQueryParameters3D rayParams = PhysicsRayQueryParameters3D.Create(from: ray_origin, to: ray_end);
Dictionary hit = space_state.IntersectRay(rayParams);

	GD.Print(hit.Keys);
	GD.Print(hit);
	
}`

The problem is that the print statements print nothing. The goal is to make an object look in the direction of mouse position.

TsenoTsenov The raycast will report a hit only if the mouse pointer is over a collider. Not sure how can that make an object look into mouse direction.

TsenoTsenov

xyz By getting the ray intersect position and rotating the object in that direction. Your first sentence helped me a lot, I added a StaticBody3D and a CollisionShape3D to my Mesh and now I am getting ray intersection position, thanks!

This is what I wanted to get and what I'm getting:

["position", "normal", "collider_id", "collider", "shape", "rid"] { "position": (1.616341, 0.135095, -0.084189), "normal": (0, 1, 0), "collider_id": 38788924720, "collider": StaticBody3D:<StaticBody3D#38788924720>, "shape": 0, "rid": RID(5557687681024) }
