Communicating distance over time for walks.

anna

I'm wondering if anyone has any helpful tips for how to communicate the desired distance over time speed for walk cycles/moving animations to Devs who are using Unity. The Devs I'm working with are overseas, there is a language barrier, and I have no access to the build (this is not ideal, obviously, but unfortunately I have no power to change that aspect of the situation). I asked them if they have some kind of unit they are using that I could use to base my numbers off of, they said "So the problem right now is that the game is actually in 3d...there's no way to give you an actual distance that is translatable." They would like me to just make them a visual guide, but we've tried that and it's really not a very reliable method, it hasn't worked very well so far. Any tips would be really appreciated, thanks!

You can use ghosting offset:

Adjust the X offset until the feet hit in the same spot, as shown there. The resulting X offset is the "pixels per frame" that the character needs to move in the X direction so the feet don't slide. The duration of a frame in the Spine editor using the default 30 FPS is 33.33ms (1000ms / 30 frames).

They should be able to map the X offset number you give them to their own movement, but only when the character is moving at a constant speed. If you mix to a running/walking animation or use an intermediate animation, the speed in-game will vary and the animation needs to match. That can be tricky to get right, depending on how complex your movement is. It can be done though, and is satisfying when you nail it!
