Is this GML or drag and drop?

And did you say this is for a contest at your programming school, and you want the forum to help you win the contest so you can win a prize? I don't know about that...

Why don't you learn the difference between object_exists and instance_exists before competing with others?

This function returns whether an object with the specified index exists or not. Note that this checks to see if an object is present in the resource tree, and not actually in the game room. For that you should use the function instance_exists.

Only people who understand the difference between objects and instances deserve to win at GML.

Does everyone in this programming contest use GMS, or is using GMS for this contest a shortcut in order to avoid a lot of work?
