Is it possible to get the bone matrix of a player?

[willjsaint]

I'm trying to find the position of the head bone of players, googling comes up with "m_dwBoneMatrix" but I wasn't able to find anything of that in the API. Is there any way of getting that info?

  "name": "m_dwBoneMatrix",
  "prop": "m_nForceBone",
  "offset": 28,
  "table": "DT_BaseAnimating"

You can get the position of the player's eyes by doing:

s.on("weapon_fire", e => {
  const player = demoFile.entities.getByUserId(e.userid)!;
  const footPosition = player.position;
  const eyePosition = {
    ...footPosition,
    z:
      footPosition.z +
      player.getProp("DT_LocalPlayerExclusive", "m_vecViewOffset[2]")
  };

  console.log(`${player.name} shot from`, eyePosition);
});

This offset should always be correct (e.g. it will smoothly change if the player is ducking). Let me know how you get on.

That unfortunately only gets you the center of the model at the height of the head, not the actual head position. I.E. if you're not at a 90 degree angle it wont be accurate.

Thanks for the help though!

Out of interest what's the application? Unfortunately the bone transform isn't networked as it's trivial to reconstruct on the client - you could do so in your application if you parsed the model file and played the animations (admittedly a lot of work!)

I'm only trying to calculate how far off a players crosshair is from the head hitbox. I suppose I could make a lookup table for the x and y offsets depending on the angle of the player and the angle of the victim but that seems like too much work especially considering my skill level with this kinda thing
