where should I input type_mask in PhysicsDirectSpaceState.intersect_ray() in Godot 3?

icqqq

In Godot 2, there is a parameter called type_mask in PhysicsDirectSpaceState.intersect_ray(), but in Godot 3 the parameter is gone.

How can I achieve the same function of type_mask in Godot 3?

Thanks

type_mask has been replaced with an array (called array) of objects or RID's to exclude.

Here's the docs on intersect_ray.

what If I want to mask out RIGID_BODY?

I'm not sure. I haven't really used type_masks so I cannot say for sure, but here are some things I would try:

| Putting Rigidbody.new() in your array of objects to exclude | Putting Rigidbody in the array | Putting typeof(Rigidbody) in the array | Putting RigidBody.new().get_rid() in the array | Putting the actual Rigidbody(s) in the array.

Hopefully one of those will work. I think you can just use Rigidbody's RID and that will mask out all Rigidbodies, but I'm not sure. Let me know if none of those work and I'll see what I can do.

Depending on your use case, you may just be able to place the objects you want to mask on a different collision layer. Then you can raycast with it checking for collision bodies only in the select collision layers. I would recommend using a raycast node if you want to go down that route as I've found its easier than trying to do it in GDScript.

Ok, I will try
