Using Hitbox Tags

We removed hitgroups in favour of Hitbox Tags, similar to how we use them for collisions. Here's how they work.

ModelDoc

When editing a hitbox from ModelDoc, you'll see Hitbox Tags. Populate them with some useful keywords like so:

Trace.Ray and Entities

To be able to hit a Hitbox with a Trace.Ray, you must call UseHitboxes() on it before Run():

API

When running traces, you'll see TraceResult.Hitbox. That'll hold all the info you'll need when interacting with hitboxes. We also pass it with DamageInfo.

Before, you'd be given a hitbox index, and that's it. It wasn't elegant at all.

With hitbox tags, it's way more explicit:

You can also grab the hitbox's name with Hitbox.GetName() - useful for debugging.
