Restrict Input Characters

['LinKin]

Hello,

I want to know how can I restrict the characters that a player can type inside an editBox

ABCDEFGHIJKLMNOPQRSTUVWXYZ

and

0123456789

How can I do that?

Thanks

There are many ways to do this, and one way is to use pregReplace in combination with guiGetText and guiSetText. You can trigger the function with the onClientGUIChanged event.

Still not clear for me

I want just to allow users to type Alphanumeric characters [A-Z] [0-9] not characters like: #¬€|@ etc..

You can use string functions.

string.find

If you don't want them to type letters or numbers use onClientKey and cancelEvent. Not sure now, if cancelEvent will cancel the event if you are typing, give it a try.

I extracted this from an old script i made. You might find it helpful.

  
if string.find(guiGetText(source),"%W") then 
    guiSetEnabled(NextStepchoosenameTXT,false) 
    guiStaticImageLoadImage(NextStepchoosename,"pictures/button_disabled.png") 
    guiSetText(errorOutput,"Your first name must not contain non-alphanumeric characters!") 
end
