ESP in Painttraverse drawing in wrong position

[itsicevenom]

I made an esp that is supposed to draw the name of the player above their head. It does this the majority of the time, however sometimes it will draw the name in the center of their body (where there head would be if they were crouched). I position the text using eyepos and raising it by 10.

How are you getting the eye position? Is it through m_vecOrigin + m_vecViewOffset or through the ShootPosition function? Also I suggest getting their actual bounding box and drawing with that, way more stable and overall a better idea imo

Through m_vecViewOffset and origin I made a bounding box and it had the same issue

Show me your WorldToScreen func

Looks about right, might perhaps be your matrix struct

Im not sure, from what I can tell the issue only occurs when the enemy crouches.
