We have a standard 2D humanoid character that needs to be able to aim/shoot in 360 degrees. I'm not exactly sure how to approach this with Spine/Unity.
I've seen solutions for this which manually rotate a bone (in this case arm) the desired degrees. This isn't a great solution for us because we also want to tilt the head and torso as they aim in different directions.
Currently we have animation states for 5 directions: down (-90°), angle-down (-45°), forward (0°), angle-up (45°) and up (90°). My hope is that we if the player wants to aim at say 20° we can set the aim animation track to an animation that is a 44% mix of the forward and angle-up animations. Or something similar that can achieve the same result.
