This sprite is 4 cross-platforms that rotate and move when Mario stands on the left or right side. The platforms sprite will stop moving when it reaches a specific Map16 tile number, customizable in the asm file.
Works as intended with no issues found, so, accepted. However, the description for this sprite was quite misleading. These platforms don't use any tracks; it will only move in a straight horizontal line and doesn't follow any type of track you place for it (it will move just fine in midair). Extending from this, the sprite doesn't need to reach a "track end" to stop. Instead, it will stop when the sprite center overlaps with a specific Map16 tile number specified in the asm file (default is 4E0 for left end and 4E1 for right end).
The rotating platform is a 4 cross platform that rotates and moves when Mario stands on the left or right side. This only works on tracks. The platform will stop moving when it gets to the end of the track.
