I use this for my random crate in my server.
[1] Onactivate -> self -> VCE_Ifvariable -> randomitem == 1 [1 3]
[2] onvariable true -> self -> setitem -> gun
[3] onvariable false -> self -> VCE_ifvariable -> Randomitem == 2 [2 4]
[4] onvariable true -> self -> setitem -> gun akimbo
[5] onvariable false -> self -> VCE_ifvariable -> randomitem == 4 [[number [number]]
If it doesn't work ima check again on my crate.
