How do make it so that you can only type in numbers with a text box and you also can’t use shift to like write something else.

#2

Maybe use the .Changed function and then check if the property is the text, if it is then run a function which removes all numbers or illegal characters from your textbox

There is a already a topic similar to this, hope this helps! I have tested it and it works. How would I create a number only TextBox?

end)

  • The variable named “Last” holds the last valid input (which can only contain numbers).

  • Every time the player types something in, the GetPropertyChangedSignal(“Text”) event fires, which runs the function.

  • The function checks if the current bit of text the player has put into the text box can be converted to a number.

  • If it can, it sets the Last variable to the bit of text.

  • If it can’t, then it reverts the text back to the last valid bit of text by setting it to whatever is the value of the Last variable.
