Hitboxes

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:

You don't need to update the Citizen's hitbox tags, we've done that for you

Trace.Ray and Entities

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

TraceResult tr = Trace.Ray(Camera.Position, Camera.Position + Camera.Rotation.Forward * 100) .Ignore(this) .UseHitboxes() .Run();

Also for the Entity, during its spawning it needs to have EnableHitboxes set:

EnableHitboxes = true;

or your ray will just hit its collision box, even when you set UseHitboxes().

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:

... var isHeadshot = damageInfo.Hitbox.HasTag( "head" ); if ( isHeadshot ) { // Multiply headshot damage by 2 damageInfo.Damage *= 2f; }

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