For a jump animation, we want move the character up in program, not in animation.
Here is my suggesition:
Add a position offset tool(for example like the circle presented in this image 图像因不支持 HTTPS 被隐藏。 | 仍然显示
)
If spine program minus the offset position value in each keyframe, we can get an animation at a fixed position.
You could animate your character in Spine, including the upward movement. Then, before export, remove the upward movement. At runtime you can move the character upward as needed. This is similar to what is done for walk cycles, where you want to move the character in the game, not the animation. There is also an offset feature in ghosting that can help.
