If you look at my projects in my profile, or the newest project in showcase, you’ll see I have a basic tile engine. I spent most of my time trying to debug its’ problems. I have a way of making the tiles load according to their size. The problem is, whenever I call the sizechanger method, it changes the size of all boxes.
Mainly I am asking if you can edit my code so that each rectangle is different when It is called or resized. I just couldn’t think of a good way. Hope you can help on my first project.
Notice
Keep in mind the copyright comment is because I used his set up and basics. I implemented the resizing and location, and how it is arranged.
