Its value can be overwritten by another system before transitions run; it is not an event queue preserving every request. Only the pending value at the transition schedule matters. [2]\n\nBy default, `StateTransition` runs before `PreStartup` and then after `PreUpdate` each frame. A request made later in the frame therefore waits for a subsequent transition point unless the project explicitly runs the schedule elsewhere. Code should not assume that requesting a destination immediately changes the current state or runs its entry systems.
