Hi, I’m trying to perform a Raycast from the camera to the world using a RayCast object. This error comes up when I run ForceRaycastUpdate()
So, how do I make the RayCast work properly? Here’s my failed attempt (C#):
Vector3 rayOrigin = camera.ProjectRayOrigin(GetViewport().GetMousePosition())
+ camera.ProjectRayNormal(GetViewport().GetMousePosition());
Vector3 rayCastTo = camera.Transform.Xform(Vector3.Forward);
RayCast r = new RayCast();
r.Translation = rayOrigin;
r.SetCastTo(rayCastTo);
r.ForceRaycastUpdate();
Vector3 projPos = r.GetCollisionPoint();
If I remove the ForceRaycastUpdate()
part, then it always returns (0, 0, 0)
I think you just missed adding it as a child of another node, before using it.
