Grid list Clicks

[Waileer]

Hello, I would like to know what should I use to get my script working. If player selects vehicle from grid list and then presses "Buy" it would spawn a vehicle he selected in x,y,z. I think i should use guiGridListGetSelectedItem and createVehicle for server sided script. But I don't know what next, I've folowed Scripting the GUI tutorial on wiki but somehow I don't get it at all, or my script is different. Thanks for answers, regards Waileer.

You could post the code here for us to find the problem in your code.

There's no problem in my code, I just don't know how I could make thing I written in main post.

Yes, you must use guiGridListGetSelectedItem and guiGridListGetItemText, then to trigger a server side event to create the vehicle, you must use triggerServerEvent.

Alright, I will try it

Hey again, well theres problem. When I select vehicle, and click button it doesn't spawn. Any thoughts?

There is no function for createVehicleHandler.

There is no function for createVehicleHandler.

What should I use then?

Try this

It's a bit different. All is good only the problem is it won't spawn vehicle after selecting it from gridlist and pressing button.
