AI Fleeing Behavior

How do I script player objects so that if a sphere at a curtain distance like 10 etc. from a cube, depending where the cube is around the sphere (like behind, towards etc.) it's Z axis will face the opposite ways of those and move away from the sphere, and if the cube comes across anything with collision that will block its path, it will head to the maximum possible point that is good enough to get away from the sphere or if it has any required components such as jumping and can jump high enough to get to the top etc.

It will do that or even if there's anything such as like things that are through out the scene that will destroy the cube, it will do the maximum possible best things to avoid them will getting away from the sphere?
