Hi there! I want to steer a tire. .. Therefor I need to rotate the tire (along the y-axis) absolutely, not relatively as it is done with SetTransform() of the Movable of a MeshWrapper object.
By using SetTransform(x), the rotation "x" is just added to the current rotation of the object. In this case if I steer right, so that the steering intensity is 1.0 the tire's y-axis rotation will be increased by 1.0 every frame. To get rid of this effect I tried the following: // in order to revoce the rotation: take the rotation, invert it and apply it on the object -> should result a rotation of zero csReversibleTransform rot_OLD = meshObj->GetMovable()->GetTransform(); rot_OLD.RotateThis(csMatrix3(csYRotMatrix(-OLD_SteeringIntensity))); meshObj->GetMovable()->SetTransform(rot_OLD); // apply the new rotation on the object csReversibleTransform rot_NEW = meshObj->GetMovable()->GetTransform(); rot_NEW.RotateThis(csMatrix3(csYRotMatrix(NEW_SteeringIntensity))); meshObj->GetMovable()->SetTransform(rot_NEW); But this somehow doesn't work well .. Does anyone know an other way for absolutly rotating an object? Greetings, Thomas ------------------------------------------------------------------------- Using Tomcat but need to do more?
