You're really putting KS+ to the test Willxinc. Thank you. I never considered what would happen if you opened two instances of the editor with the script panels open. It uses a temp.ini to write temporary script changes to. All instance of the editor will use the same file. I better change that. Each world should have it's own temporary script. *gives star*
The KS+ Instructions.txt is mainly for new script instructions and graphical guidelines, but I suppose I should describe every new object as well, especially if an object isn't covered by any of the example levels.
Objects 0:248-255, simulate key presses when Juni collides with them. I didn't have a clear reason for adding them, but I thought creative people could find good uses for them. The arrow objects, 0:252-255, are not one-way objects, though they can be used to that effect.
For your other issue, there's a good reason the delete object doesn't work on those invisible blocks. They aren't there. The object is created when the screen is, but then it draws itself into the collision mask and destroys itself. If you use object 16:13, your gate will work correctly. This object only stops Juni, but you can layer on bird and creature blockers as well. By the way, that example is really neat.
