If I have a map in my platformer game and I want my character be able to jump on some platform, for example. Is there an easy way to tell the game where the platforms are and where the player can jump to and start jumping from?
Also, for games like Super Mario Bros and such, are the maps made in .txt files ? I watched a tutorial for maps and he said all professional game developers make a .txt file for the map and write numbers for example using...
111111111111111111111 111111111111111111111 111111111111111111111 111111111111111111111 222222222222222222222
...to create a map. Is this correct or how did the developers do the maps in the Super Mario Bros or MegaMan games?
What I am wondering is, if I want my player to be able to jump up on some platform or something, how do I do it?
