AnimationPlayer (3d) : play only part of animation track ?

siska

I'm porting a point&click game, and I'm kind of scratching my head over something that should be simple ...

I'm trying to create an animation for the lock circled in blue. When you click the ball, it should move to the center, when you click it again, it should move right, and finally, when you click again, it should move all the way to the left again.

My idea was to create 3 key frames for the 3 ball positions, and whenever the ball is clicked, play the animation to the next keyframe (with 'loop' set to true). Unfortunately, I can't seem to find a way to do that ... ?

There's an animation play_backwards. So you could have left to center and right to center. I don't know it well enough to stop at a keyframe. Maybe. or just move it with code or tween, or just add tracks moving left to right with two keyframes.

Yeah ... Looked at it some more and there really doesn't seem like there is an easy way to do it. Shame ...

It's possible to use the animationtree node of course, but that's a bit of a hassle for what I'm trying to do. You could also use several tween nodes instead of an animationplayer ... but also not convenient. So ...

my hacks : 1) animationplayer.seek(time_in_sec, true) 2) animationplayer.advance(time_in_sec)

=> 'scrub' the animation to the frame at time_in_sec ; this is NOT the same as play() !

3) add a method track to the animation ; call animationplayer.stop(false) on the key frames

Have a separate animation for each phase.

Yes, I know that's another way of doing it, but again, in my use cases, a bit of a hassle to have to correct animations play next ... =)

I would use a tween and a "next_position" variable. Why would you need several tweens?

@7892 : It just seems easier to set up with multiple tweens ... Every button press needs to play 'the next' animation/tween. So, I need a var to keep track of the press 'count' to play the correct tween + loop back to the first one. And 1 tween contains 2 vars : pos_from and pos_to ...

I might be missing something though. I hardly ever use tweens. =)
