  • New Spine user.. stuck, question on animation

    anglais

Hello all, and thanks for taking the time to assist a new user.
I just picked up my license for ESS yesterday, and have gone through much of the docs and video tuts.
In the Video for Key Frames (part 1) around the 5 minute mark there is a demo showing a simple bone, being animated / rotating.

So for my first test, I made a simple square block, created a new bone, and connected it to the default bone, and attached my block graphic. in my this test around frame 15 I rotate the block 45 degrees and key frame it. But when I play the animation back or scrub through it.. I am seeing no 'tweening' my block simply stands still, then jumps to the 45 degree mark. I even exported it to .gif files for each frame and can clearly see no tweening, just a static block then the final image it's rotated? My expectation was to see a smoothly rotating block similar to the bone example in the video. Below is my frame by frame output, note static placement, until the final frame where it jumps to the 45 degree position.

So obviously I am doing something wrong.. but can't seem to determine where.
I realize this is the fundamental concept of what Spine does... but sadly I am not figuring it out on my own.. although the tutorial seems straight forward enough... I must be missing a step along the way.

Thanks for any replies.. I am anxious to start animating my artwork... but if i can't even make a block rotate I am screwing something up, or just not familiar enough with the software yet to determine what I am doing, and am stuck scratching my head at the moment.

Welcome to Spine! 🙂

It sounds like you didn't create a key at frame 0, so Spine doesn't know which value you want to "tween" from.
If you create a key at frame 0 with rotation = 0, and then a key at frame 15 with rotation = 45, you should get what you're after. You should also see a line between your two keys, once the value between the two differs.

It helps you know what the lines between keys mean, here's a snippet from our documentation Dopesheet - Spine User Guide: Keys:

Straight lines between keys indicate a linear transition. Slightly curved lines between keys indicate a Bézier curve transition. Dotted lines between keys indicates a stepped transition. No lines between keys indicates either that both keys have the same value, or that the type of key does not have a transition (such as event keys). Note that overview rows never display lines between keys.

I hope this helps.

It helps. That is what I missed. Thanks
