There was an stun timer released before https://www.mpgh.net/forum/showthread...%27s+StunTimer
The source is either in that post or in this post: https://www.mpgh.net/forum/showthread.php?t=1167294
Im not sure if the plugin is outdated or not, i would try the plugin from each post to see if one or the other might still be working. If not i dont think it would be too much work to update the source, not much has changed id think.
