Leap Attacks, Jumping, etc

Majicpanda

I've noticed some animations in the showcase have animations where the anim moves the character on the Y when jumping and X for leap forward attacks. This is the opposite of what we did where everything is animated in place and all movement is done in unity. Just trying to see what everyone else does because animating the X/Y results in colliders not moving with them and interesting challenges like updating the ground collider at the new position of the character.

Most of the time, you want to keep your character in place. However, there may be situations where you want to apply something called root motion, essentially drive your character attributes by the animation itself. Here's a good article on the topic: https://docs.unrealengine.com/latest/INT/Engine/Animation/RootMotion/

The animations that don't stay at the center position are mostly that way for demo purposes. But like badlogic says you can also look into root motion.
To illustrate the benefits of root motion, imagine a zombie who doesn't move at a constant speed (slow staggering steps). With root motion you can get that behavior. Without the zombie will most likely movery at a constant speed.

We've got a really weird behavior monster that swoops down and through the player and its hitbox needs to go with for attacking it, but this still might be better accomplished with some sort of AI movement behavior custom to it instead.

You can attach and animate bounding boxes in the edito and use that for collision detection. They don't necessarily have to align with the visual parts of the character.

I had really bad issues with bounding boxes not properly disabling when mixing and had to give up on them completely. There were way too many animations and situations where the frame to disable or enable was missed because an animation changed before the key was reached. I tried to code in some full disable all colliders on anim changed but there are too many cases to cover.

This shouldn't be a problem in Spine 3.5.
A number of AnimationState improvements predictably handles attachments in general during mixing, and attachment keys relative to setup pose.
