Types

type AnimClipMode 

type AnimClipMode byte

AnimClipMode determines how time is treated outside of the keyframed range of an animation clip. 

const (
	// AnimOnce - When time reaches the end of the animation clip, the clip will automatically
	// stop playing and time will be reset to beginning of the clip.
	AnimOnce AnimClipMode = 0
	// AnimLoop - When time reaches the end of the animation clip, time will continue at the beginning.
	AnimLoop AnimClipMode = 1
	// AnimPingPong - When time reaches the end of the animation clip, time will ping pong back between beginning
	// and end.
	AnimPingPong AnimClipMode = 2
	// AnimClampForever - Plays back the animation. When it reaches the end, it will keep playing the last frame
	// and never stop playing.
	//
	// When playing backwards it will reach the first frame and will keep playing that. This is useful for code
	// that uses the Playing bool to avoid activating said trigger.
