I tried to learn the APGB tutorial, but I found that one problem is that my jumping performance is not ideal. Is there any way to teach me

Well, jumping isn't really part of the action RPG tutorials.
If you're using root motion (like the tutorial), the available jump feature of the Button player controls will not really work well - you can instead set it up as a separate action like the roll action.

Alternatively, you can use custom controls to add better control options. ORK's built-in controls are only there to get you started, since ORK is an RPG framework and not a player/camera controller :)
