Script: Simple Addition Calculator

Code (put in Create event of an object)

firstno=0
secondno=0

firstno=get_string("Insert the first of the values.","5")
secondno=get_string("Insert the value you want to be added to "+string(firstno)+".","10")

show_message("The result of "+string(firstno)+" + "+string(secondno)+" is "+string(firstno+secondno))

How it works

This is a very simple script. It basically asks the user to input two values, then adds them together and outputs the result.
