DF_Patch_Stuff

Some patches for DeFRaG. Pretty much only contains grappling hook trail fixes and custom savestate and restorestate commands for now. The custom commands can save/restore:

• Timer
• Health
• Armor
• Items
• Weapons
• Frags
• You get the idea...

Installation

// TODO (#12): Fill this in

Usage

This was pretty much made for mapping/testing purposes. So:

• It can only be used in devmap (sv_cheats 1)
• To use it:
  1. /set savestatename <whatever>
  2. /savestate
  3. Tweak <whatever>_* cvars if you want (read the source code for format/order of each cvar)
  4. /vstr <whatever>

Limitations

I would only use this for convenience (ie. when you don't have a bot/replayer or don't want to switch to it) and not for any ultra precise and accurate testing (just use the bot/replayer). Anyways, some of its limitations include:

• All the flaws of the original savestate/restorestate (ie. ob) and possibly more...

• You can only use this on patched servers (you won't be able to restorestate on unpatched servers)

• It doesn't store world state. For example:

  Suppose:

  • You savestate after firing a rocket/grenade/whatever
  • You restore using /vstr <whatever>

  Then:

  • You will restore with whatever ammo you had and everything
  • But the rocket/grenade/whatever you fired won't restore
  • It's possible to restore these, but at some point you are going to have to draw the line somewhere:
    • Are you going to restore the way the doors/triggers/etc were?
    • Too much effort, too lazy, just believe in a replayer at that point

• Restoring in fastcaps is a bit broken depending on how you view it:

  Suppose:

  • You are on the red team and have the blue flag
  • You savestate, switch to blue team, and vstr

  Then:

  • You will restore as a blue team member holding the blue flag :D
  • I'm not sure what the expected behavior would be for such a situation
  • I could always restore you with the opposing team flag instead of whatever was saved at the time of savestate
  • Too lazy though, you can manually toggle two bits in <whatever>_items for now

• It might stop you from using proxymods/cheat engines that checksum the VM or have hardcoded pre 1.91.27 offsets

  • The data offsets for the patched VMs should be the same as the original VMs

Note: There is supposed to be one more person here, but the proxy was so good, I have no idea who it is.
