Warps

I have decided to create this page because many people have been asking me how to make warps recently.

This document by GmdDoesDMG does a great explanation of the process:

If you want to make warps that are NOT success and failure warps, the process is mostly the same. Simply treat the level that you want to end up in as the "overworld" in the tutorial, and the other level as the actual level.
You also need to take the following differences into account:

• You will be using different kinds of objects, such as warp hole / warp pipe and Warp (Mario Start 1).

• You'll have to give the warp in the first area its own source warp ID, which works the same way as step 3 in the  shown document.

It is also recommended that you NEVER use warp ID 0 for any of your warps unless you know what you're doing, as you may accidentally create a wrong warp to a star.
