Mix walk-animation and run-animation to jog

Camilla

Hi,

I am using unity-runtimes. How do I mix a run-animation and a walk-animation to create a jog-animation. Is it possible to do it without using Mechanim and blend trees?

Camilla

I have found out that I can use the Apply method in the Animation class. It worked when I added the UpdateWorldTransform() on the skeleton.

You can use the AnimationState API (higher level) or the Timeline API (lower level):
Applying Animations - Spine Runtimes Guide

Eg:

state.setAnimation(0, "walk", true);
TrackEntry run = state.setAnimation(1, "run", true);
run.alpha = 0.5f

See TrackEntry alpha. You can adjust alpha between 0 (all walk) and 1 (all run). Between 0 and 1 is a mix of the two. You can easily experiment with this using Preview in the editor:

Thanks for your answer. That works fine for jogging. But when I use this on a pick-up-animation it seems like the shoulder joint isn't properly cleaned. For instance if you have a pick-up animation that mixes two pick-up-animations It works fine. But if the next pick-up-animation only play on one track with alpha=1 I would expect it to overwrite all the tracks. But it doesn't it is affected by the previous animation. It works fine if I clean all tracks between the animations.

Animations on higher tracks only affect what they have keyed, This allows you to do things like play a running (or walking, swimming, etc) animation on track 0 and a shooting animation on track 1.

Thanks for you answer. But I had the problem when I mixed two or more pickup animations that uses the same joints. But if I make sure to clean all the tracks from the previous animation before starting a new one it works fine. So I don't have the problem anymore.
