Based on L. Duke's jump pads plugin.
Lets you place permanent jump pads on maps with settings in a config file. If I find a way to read files from inside a .bsp, I will switch to map specific configs to make releasing maps that rely on this plugin easier.
Commands
sm_padsreload - Reread the config file
sm_padsremove - Remove all jump pads from the map
Config file goes in configs (configs/pads.cfg). Example config attached.
Origin: where the bounce pad is placed
Angles: rotation of bounce pad
Velocity: velocity of players after they touch the pad
Model: bounce pad model
Sound: sound played when bounce pad is used ("" for none)

Doesn't compile on the forums so download the smx or compile it yourself.
