Question Problem with Raycast and Visual script.

Hello everyone, please help me solve the problem. I need raycast not to work on several specific objects. If I understand correctly, then I should create a layer that will contain all these objects, and then create a layer mask for this layer. Am I thinking right? If I'm right, how can I create a layer mask for this layer using visual script?
P.S. I'm a complete newbie to Unity and programming, I'm currently trying to make a 2D game.

 

Just create a new Layer as usual: https://docs.unity3d.com/Manual/create-layers.html

Assign the layer to a GameObject you want the raycast to hit.

Then choose 2D raycast node that takes LayerMask as input value and do one of these options:

1. LayerMask Literal node + LayerMask Get Value node.
2. AoTList Literal with one or more strings + Get Mask node that takes layerNames as input.

EDIT: "Custom" is just a new Layer I added myself.

 

Thank you very much, your answer helped me.
