How should I handle multiple clip types?

[Withaust]

In my game I have a clear separation of clips that are applicable ONLY to players, ONLY to NPCs or to both at the same time, something simular to what Source does with Player Clip, Npc Clip and Clip. I was wondering how I should set this up, since func_godot only seems to be supporting only one clip type.

We don't expose mapping textures to specific collision masks/layers as shapes in Godot can't have different collision masks/layers between faces, and an arbitrary amount of entities might have to be created per brush.

That said, there are a number of ways to implement this that are really up to your own preference.

The simplest is likely having different entity classes with their definitions placing them with different collision layers or masks. For example, func_clip, func_playerclip, and so on.

You could also expose a choice or flag property, read it in _func_godot_apply_properties and change the layers for a single entity (or family of solid entities). This might require some more setup, but would let you extend this to any solid type you like.

The benefits of reading properties can include some common handling between different Godot script classes. An example of this I've used to achieve was a shared apply_common_solid_properties(entity: CollisionObject3D, props: Dictionary) static method in a utility class that something can call in its apply properties with self and the properties dictionary supplied in _func_godot_apply_properties. In my case, it handled reading properties for collision layers, as I had a lot of solid classes with surface flags to replicate Quake 3 behavior.
