How do you check if something is a player?

[-=>RR<=-MasterCE]

You can't as what RTB did would actually be considered a type of exploit to opennig thigns on a client...you could actually spam that command and annoy the crap out of people on your server. No crap like that in Retail.

But how do i make it open for only the person that did it? Like when you hit something with a wrench, it opens the wrench gui. How i have my thing now, you hit something, and the gui opens for only me.

Badspot placed a callback to open the wrench menu, you'd have to force everyone in your server to place your callback in their game to make yours work

Opening windows on a client is not an exploit. If the server owner is spamming that command, then i'm sure the clients will leave and not stick about for further abuse.

[-=>RR<=-MasterCE]

It is an exploit, but a positive one untill someone spams it, as you said. If the person is building something and this happens, that's not fair :/

So you're saying it's not possible? Or you have to add something to everyones game?

[Resonance_Cascade]

You'd have to add something client side, which everyone would need to download.

[Game master pro]

Well they'd have to download the GUI in the first place, so couldn't i add it there?

[-=>RR<=-MasterCE]

yes, you never said it was it's own gui everyone would need too.....

[Game master pro]

Yes, it's a custom GUI. So how would i go about making said callback?

[-=>RR<=-MasterCE]

newcallback(GUI,'openmy****inggui');

[Resonance_Cascade]

addMessageCallback('Name of Callback', functionToCall);

[-=>RR<=-MasterCE]

then like
messageclient(%client,'Name of Callback','stuff to send');
