6.数据-枚举

枚举

枚举基本上是常量的简写，如果您想为某个常量分配连续整数，那么枚举非常有用。

如果向枚举传递一个名称，那么它也会将所有值放入该名称的常量字典中。

enum {TILE_BRICK, TILE_FLOOR, TILE_SPIKE, TILE_TELEPORT} # Is the same as: const TILE_BRICK = 0 const TILE_FLOOR = 1 const TILE_SPIKE = 2 const TILE_TELEPORT = 3 enum State {STATE_IDLE, STATE_JUMP = 5, STATE_SHOOT} # Is the same as: const STATE_IDLE = 0 const STATE_JUMP = 5 const STATE_SHOOT = 6 const State = {STATE_IDLE = 0, STATE_JUMP = 5, STATE_SHOOT = 6}
