Softlock from Spawning a Star Too High Up & The 12k Limit
I show a softlock that occurs from spawning a star too high up (i.e. above y=12000), and then explain the 12k limit. To summarize, there's a function in the game (obj_move_using_vel_and_gravity) that manages how certain objects move. However, it will only move the object if the coordinates of the object's position have absolute value less than or equal to 12000. When spawning a 100 coin star, the star goes through certain actions before telling the cutscene to end. The first of these actions (action 0, or the star's first bounce) won't end if the star's position is prevented from updating due to being outside the 12k limit, and so a softlock occurs. Also, thanks to JoshDuMan ( / joshduman ) for showing me the code responsible for the 12k limit.
