As you may already know JME’s new animation system has a BlendAction feature that is used to blend multiple animations together (like walk and run animations). But it requires the animations to have the same length otherwise it will internally stretch any animation that does not have the same length. Stretching animation might introduce a slow-motion side effect.
For example, here I am blending “walk” and “run” animations. The walk animation is 1.5 seconds, and the run animation is 0.5 seconds. BlendAction will internally stretch the run animation length to be equal to the walk animation. So the run animation will also be 1.5 seconds.
Here is the blending result:
Here you need to increase the speed as it blends toward run animation and vice versa.
I have made a PR to automate this, so BlendAction will automatically adjust the speed for you. It will calculate a factor to be applied to speed based on the current blend weight taken from blend space.
