Just gonna leave this here for now. I didn't have time to test and don't want to create a whole thread without testing. Feel free to try it out.
This is just a tiny plugin to showcase the L4D_OnLedgeGrabbed forward. Pretty much it allows you to control if a survivor will grab onto the ledge when they are being smoked or jocked.
Code:
"l4d2_lc", "1", "On/Off for the plugin.
"l4d2_lc_jockey", "1", "On/Off switch for Jockey ledge grab"
"l4d2_lc_smoker", "1", "On/Off switch for Smoker ledge grab"
