State

enum class engine::platform::Key::State

strong

The state of the key with regard to whether it is pressed or not.

Enumerator
Released	The key is up.
JustPressed	The key has just been pressed in the current frame. This state only lasts for the frame in which the key was first registered as pressed.
Pressed	The key is being held down. If the key was JustPressed in the previous frame, and it is still down in the current frame, its state transitions into Pressed.
JustReleased	Lasts only for the frame in which the key was released. In the next frame, if the key is not pressed again, it transitions into Released.
