Hello, complete noob here.

Currently, I'm working on a platformer game and I need a bit of help with one of the extensions. So, what I want to happen, is for the game to load levels in the same frame instead of seperate frames. I was able to discover Tiled Map Loader and the Tiled Program. I made a level (with setpieces and stuff) and exported it as a .xml, when I made a "Start of Frame" event to load the map, nothing happened and it just played the test level I had already built into the frame. So, I'm kinda confused right now, and I have no idea what to do. If anyone has any tutorials I can look at or any tips or anything helpful, that would be most appreciated, Thank you.
