Unducking inside of a teammate causes prediction errors #2107

Open sapphyrus opened 5 years ago

sapphyrus commented 5 years ago

Please describe your issue in as much detail as possible:

When unducking inside of a teammate the game incorrectly predicts a few related netvars, causing an ugly teleport (if moving), view stutter

Steps for reproducing this issue:

  1. Go into an offline server
  2. Set the following cvars:
    • mp_solid_teammates 0 or mp_solid_teammates 2
    • net_fakelag 1
    • cl_showerror 2
    • cl_pdump 1
    • bot_stop 1
  3. Add a bot. place it somewhere, move through him and duck, then unduck. Your view will stutter, you will teleport a bit. Several netprops will be red in the cl_pdump output and the follwing error log will appear in your console

You might as well not bother posting anything. They won't fix any issues posted here, and they won't respond or patch anything you email to them. This doesn't affect their revenue therefore it won't be looked at. There are prediction errors like crazy by simply crouching while in air or crouch walking. They spam the console 24/7. Base velocity isn't even networked, so prediction errors will be spammed when standing on conveyer belts, Velocity isn't networked, Pose parameters are not networked, usercmds are not animated on the correct tick, resulting in exploits with animations and desynced hitboxes, among so many other bugs that they simply DO NOT CARE about. Good luck
