Mewtwo Strikes Back
Even if this work somehow, it's way unprofessional IMHO. You can clearly see the player in the modified truck before it gets warped in the new map.
That, and the fact you need to edit the map/tiles/scripts doesn't really fancy me. Here's a video so you can see the way I made it and compare it with yours.
BTW, why calling it a script when it's actually pure ASM?
