Thank-you both, As I am working with .sqs (I know get with the times man) would the correct syntax be
if (isServer and (isNull player)) then {exit}
I have fixed the Carbomb script, changed variable "carbomb" to _this, and removed the scripts dependency on a marker so now a Logic is created at trigger point instead, and the all the effects now call on the created logic, is this better for MP than using a marker? srry I am a noob at the mechanics of MP scripting.
Also should I add a server check to all scripts?
Thx Odin
