Scripts not working online.

[Link3001]

Hey there!

I have been trying to revive X-Online and I must say that the new engine and everything totally confuses me.

I used to have Grim Squeaker (I bet some remember him) around to do the scripting for me, but he's been gone for ages and now I am on my own.
It's just too bad that I know nothing about scripting (except for some simple, old scripts) and therefore I fail at trying to fix his old scripts.

Now, one of those happen to be lighteffect scripts. They work perfectly offline, but once I try to test them online, they are not even showing me the slightest bit of light.

So what am I doing wrong here?

[edit]:

So someone told me to make it Clientside (I had no idea I had to..).

So when should I made something Clientside or serverside?
