How would one make or get this script?

Hi, I need a script that does the following after i press shoot. I will put it up in trigger and actions:/

Trigger:
Left mouse btn is pushed

Action1:
R (reload)

Action2:
Wait 0.1 seconds (is it easy to change this value in the script)

Action3:
Mouse button 4 (switch weapon)

Action4:
Mouse button 4 (switch weapon)


Any responses would be very much appreciated since i am starting to get cramps doing this myself:/ A redirect to a forum concerning the easy scripting would be appreciated, a script or hack that does this would be amazing

AHK (auto hot key) but really not a favourite of mine
