As the title suggest, I have a body that I want to rotate manual depending on the direction of the sprite. I set fixedRotation to true so I don't have my sprite spinning around when it hits an object. But I am having trouble finding how to rotating a body manually? Any help is appreciated

You can move and rotate a b2Body using "SetTransform"

float angle = 90.0 //or whatever you angle is
b2Vec2 pos = body->GetPosition();
body->SetTransform(pos, angle);

Also, you can use ApplyTorque and perhaps setAngularVelocity methods.

But please note, that neither of these methods will have any impact if the FixedRotation is set to true.

b2Body eagleBody;
....
//Bank Left
eagleBody->ApplyAngularImpulse(1500);

//Bank Right
eagleBody->ApplyAngularImpulse(-1500);
