[SOLVED] Rotation-Based 3D Weapon Sway | Undocumented Functions

[gzedbone]

I'm trying to implement weapon sway where the rotation of the weapon lags behind the camera's rotation, think Half-Life 2 or Dusk for example. The sprite-based weapon sway in doom mods is position-based for obvious reasons. However, I have looked at the code for Disdain, and the 3d weapons lag behind based on their positions too, and looks like there doesn't seem to be a way to rotate 3d weapons at runtime outside of their MODELDEF definitions.

However, after looking through the ZDoom wiki, I have come across these 2 virtual functions: ModifyBobLayer3D and ModifyBobPivotLayer3D. [wiki]https://zdoom.org/wiki/Weapon_virtual_functions[/wiki]
For the first function, there's only info on its arguments (which contains rotation), and the second function has not been documented at all. I have also looked through the GitHub repository, but could not find any info or examples on using these functions in code.

EDIT: I figured it out on my own. Here's how to use them:
//--------------------------------------------------------------
//Inside your Weapon class:

override Vector3, Vector3 ModifyBobLayer3D(Vector3 Translation, Vector3 Rotation, int layer, double ticfrac) {
//modify the values of Translation and Rotation here;
return Translation, Rotation;
}
