Advice on combining animations

msm

Hi,

I was hoping to get some advice on the best way to combine animations. Please excuse my ignorance regarding animations in general, I'll admit that upfront (I hope that is more of a testament to Spine that it has allowed me to actually produce something easily).

I am looking to implement something like what is described in the documentation here:
http://esotericsoftware.com/spine-using ... animations

I have a character with various animations, walk, crouched walking, crawling, etc. I also have a shooting animation where I'd like to have his right arm extended out in front of him.

I currently have it implemented fine for the walking/shooting scenario. But when it comes to the others, crouched walking for example, my setup doesn't look right. The issue is that the crouch animation has the torso rotated as the character is hunched forward. My shooting animation only rotates the arms in relation to the vertical torso as in the walk animation, which means the arms point straight down at the ground when he is hunched over in the crouch.

Same goes for the crawling animation where he is lying on his belly, I'd like the shooting arm extended inline with the torso alongside his head.

Can I achieve this with one shooting animation combined with the others, or should I create separate walk-shoot, crouch-shoot, crawl-shoot animations ?

Thanks for the help

You can do it with a single shooting animation. You can tweak the setup pose programmaticly, so what you want to do is rotate the upper arm bone.
For example.

Bone upperArm = skeleton.findBone("upperArm");
upperArm.data.rotation = 90;
skeleton.updateWorldTransform();

You can 1) adjust the setup pose, or 2) the keys in the animation, or 3) the bone rotation after the shoot animation is applied but before updateWorldTransform. For 1 and 3 if you just rotate the bone eg 90 degrees when applying the shoot animation, it will jump those 90 degrees instead of being animated. You could programmatically adjust the bone rotation for shooting without using an animation, or by using a shooting animation for everything except for a single bone (eg the shoulder) which you then rotate to point the arm in the right direction.

Thanks guys. I am going to go with your last suggestion, animate the lower arm and hand, but programmatically rotate the shoulder since I am going to need to aim at other various angles anyways. Thanks for the help
