2d - 360 degree gravity game mechanic like “They Need To Be Fed” game -


i fan of "they need fed" game , want understand game mechanic @ deeper level. resources basic box2d (or similar) physics behind 360 degree gravity game mechanic ?

first of all, understand how make character orbit circle or box without falling down using box2d or similar physics

from understanding, need set world's gravity 0 , apply centripetal force character.

i have searched around web tutorials ideally answer above questions , perhaps provide additional resources regarding efficiency, camera motion , on haven't found anything.

try using changing gravity

-(void) changegravitybyxvariant:(float) xvariant andyvariant:(float)yvariant{     world->setgravity(b2vec2(xvariant, yvariant)); } 

i have tested , works..... can't find easier
