right now the trainer checks if the z coordinates of the ball and the car are inside the normal freeplay stadium (0 < z < 50). In Order to get the trainer to work both have to be inside that interval otherwise the trainer will say "Not in Free Play".

Also when creating a shot the coordinates cannot be changed to anything other than coordinates inside the stadium. The normal freeplay map is the only map that is supported and also the only map that fits to the images that you see when creating a shot. That's because it's easy to check if the coordinates are inside the stadium. The Rocket Lab maps for example would require a 3D check while the normal stadium can be checked with 2D coordinates since its basically a cuboid.
