unity3d - Unity - Walk around a cube -

i have issue trying 'object(character)' walk around cube (all sides) within unity. ive attached image , video showing trying achieve. im trying show visually rather trying explain. character drops on edge rotates 90 degrees , stands gravity has switched. character can jump walk etc.

this example of else posted video showing im trying achieve

i have looked through forums , cant find im after. have tried attach diagram site wont let me. advice appreciated!

regards

you have couple of options can think of.

one trigger gravity change when character exits 1 face of cube go another. achieve have trigger zones on each edge , face , use [bob went face edge anorth -> switch gravity go in x direction].

this work situations gravity switch must affect other objects advantageous player (walking off side makes enemy fall off , die - example.)

however, if want entities stick relative sides need make custom gravity! easier might think gravity downward accelleration of 9.8. turn off engines native gravity , create "personal gravity" component:

private vector3 surfacenormal; private vector3 personalnormal; private float personalgravity = 9.8f; private float normalswitchrange = 5.0f;  public void start() {         personalnormal = transform.up; // start "normal" normal     rigidbody.freezerotation = true; // turn off physics rotation     }  public void fixedupdate() {     // apply force taking account character normal personal gravity:     rigidbody.addforce(-personalgravity * rigidbody.mass * personalnormal); }  

rotating character , changing normal suit situation or game mechanic, whether raycasting if you're standing on surface detect when change or want gravity change when hit powerup or similar - experiment , see works. comment more if have questions!

edit:

as addition video linked. can keep state variable on jump state , raycast in each axis direction check face nearest in case of rolling off.

public void update() {     // don't update personal normals in case of jumping     if(!jumping)     {         updatepersonalnormal();     }  }  public void updatepersonalnormal() {     raycasthit hit; //hit register     // list of valid normals check (all 6 axis)     ray[] rays =          {         vector3.up, vector3.down,          vector3.left, vector3.right,          vector3.forward, vector3.backward         };      //for each valid normal...     foreach(ray raydirection in rays)     {         //check if near cube face...         if(physics.raycast(raydirection , hit, normalswitchrange)         {              personalnormal = hit.normal; //set personal normal ...              return; // , return done         }     } } 

please keep in mind above hand written , not tested play , pseudo start should give idea of do.
