Hey all. I was struck by inspiration and have a neat game idea that I think I'll be able to make using the free version of C2 (I hope).
I've run into a bit of a snag though. At the start, the player needs to enter in their name. It is crucial that they enter a name of some kind, and not just leave the field blank.
How do I check to see the input of the textbox, and have the game give an error when the value is "null", or nothing?
