A garage/dealership engine of my own creation for my game Race Demo 1. So far, you can buy sprites, select them in the garage and move said sprite (only up and down, but it is a test, so who cares) Basically, along with the show/hide functions, there is a list for the garage, any item on that list can be selected, otherwise a message will show up saying you can't select it. Clicking a sprite in the dealer or garage is run along broadcasts and if-then-else statements to select the correct function (the garage/dealer background code is in the backdrop so it can be used universally)
All code by me. Yeah, that's right. No using others code, no tutorials, I made it all by myself. You can use this engine if you feel fit, just make sure to credit me.
