No description of the "mask" parameter of the "raycast" method

There is no explanation for what the 'mask' parameter (for the 'raycast' method for 2D physics) does in the docs. I want to use this parameter but I don't know how.

Here's the link to the API doc: https://docs.cocos.com/creator/api/en/class/PhysicsSystem2D?id=raycast

The mask of the ray-cast is related to the physics grouping, and this part is the same inside the 2D and 3D physics, which can be found in the following document:

https://docs.cocos.com/creator/manual/zh/physics/physics-group-mask.html

Thanks for the link. I was not aware of this page since I only looked at the Physics 2D section. I think it would be very helpful if you could add links to these pages inside the 2D section so people can find them easier.

Thanks for the feedback, we have added the relevant links in v3.6
