A Sourcemod plugin for TF2 jumping that adds various improvements through optional settings without affecting the core gameplay. Only works on Linux servers (for now) and requires a newish version of Sourcemod 1.11 (>=1.11.6820).
Players can use /jumpqol (sm_jumpqol in console) to see the available settings with descriptions. If a setting is more than just an on/off setting, then /jumpqol <setting> will show what the possible values that can be used are. Finally changing the value of a setting is done through /jumpqol <setting> <value>.
The server can similarly use sm_jumpqol to list all the settings along with the default values. The default values can be changed with the ConVars sm_jumpqol_<setting>_default and it is possible to enforce the default values by setting the ConVars sm_jumpqol_<setting>_enforce 1. A config file for these ConVars gets generated at cfg/sourcemod/jumpqol.cfg.
For finer control, the jumpqol.inc include lets other plugins control what setting values the players should have and informs plugins when they try to change them. An example of such a plugin can be seen in example.sp.
