[ANY/CS:GO] Backtrack Elimination (1.2)
 

About:
This plugin is a short and simple fix for the backtrack exploit.

Description:
Backtrack is a popular feature in cheats. It's an exploit that makes delayed aim act as proper aim.
It works by logging the players' hitbox positions for the X previous ticks, and then abuses the game's lag compensation in order to make the server think that the player is hitting someone even though in reality, their aim is incorrect and delayed.

This plugin works by not allowing players to repeat the same usercmd->tick_count values they did before.

Examples of backtracking in action:

Settings:
backtrack_behavior (default, 1) - Should the plugin be enabled?
0 - no
1 - eliminate backtracking (fix the exploit)

This plugin creates a config file in cfg/sourcemod/. You can edit the setting(s) there.

Changelog:
1.2 - Fixed the usercmd choking issue. Removed kick/ban as they're actually not a good solution for such a plugin.

1.1 - Changed plugin behavior to prevent issues caused by the nature of UDP. Auto-banning and kicking can be now enabled! No more false positives and this shouldn't ruin lag compensation by legit players.

1.0 - Initial release.

Notes:
This plugin is incompatible with the SMAC Eyetest module.

To the 9 people who downloaded the attachment before, I accidentally uploaded the unfinished .sp file from my PC rather than the updated one on my OneDrive, my bad. The previous one was very problematic.

Thank you for releasing this plugin! Its much needed since backtracking is kinda annoying to deal with.

Comp w/ Sourcebans?

Re: [ANY/CS:GO] Backtrack Elimination (1.0)
 

No. Kick/ban are only intended for LAN servers. If you're running a community server, leave it on 1 (fix but don't kick/ban).

False positives with SMAC Eyetest module should not happen now too.

Fixed. Haven't noticed it because I only tested in LAN, sorry.
