wondering if theres a way to have a script load when you morph into another alien..and was also wondering if a script can be activated automatically when you spawn. my idea is this

skulk > Fade : script loads automatically when you morph into fade

death > respawned skulk: a script that can automatically loads when you respawn (might not be possible)

Impossible, since scripts cannot react to what's happening - meaning they can't change according to the situation. You have to manually activate the scripts for each life-form - something like this:
bind "f5" "exec fade.cfg"
And in fade.cfg, you have all the commands you want it to execute. Like
sensitivity 27
bind mouse1 +use (whatever )

for fade - bind "key" "impulse 116 ; exec fade.cfg"

in fade.cfg have everything that you want to change from your original config
