I'm one of those people that will spend hours trying to learn by myself (and I have) while trying to wrap my head around why adding more than two "Tele" methods cause all of the Tele methods to not work (the mouse gets stuck in a teleport loop). I hate asking for help. On top of that I'm also one of those people that will want to know WHY something doesn't work and not just, "That doesn't work, try something else." Which is another reason I hate asking for help. I know a lot of people that respond negatively to the question, "Why?" The first two methods (hitTeleOne & hitTeleTwo) work exactly as I would expect them to when they are the only two methods that are active. However, the moment I un-comment out TeleThree through TeleSix it all goes crazy, and the poor mouse gets stuck in space-time continuum.
The rest of the code (classes and subclasses) are all set up in a very basic "I'm learning" style and I fully understand that there is a better way to go about it.
credit to Danpost for the Tele code I found while Googling my heart out trying to figure this out.
Setup:
World
--MyWorld
Actor
--Cheese(pizza bc Greenfoot doesn't have a cheese image lol)
--Mouse
--Teleporter
...........^-- TeleOne
...........^--TeleTwo
...........^--TeleThree
...........^--TeleFour
...........^--TeleFive
...........^--TeleSix
--Walls
..........^-- *a bunch of WallHeightSmall/XLarge and WallWidthSmall/XLarge
There is no out of the ordinary code in any other area other than the Mouse class (which is posted below). Everything else is your basic Scaling images down and obviously all the addObject code in the MyWorld class.
