In cocos2d-x, I move a sprite with ccbezierTo like this:

// use for ccbezierTo
bezier.controlPoint_1 = ccp(m_fish->getPositionX() + 200, visibleSize.height/2 + 300);
bezier.controlPoint_2 = ccp(m_fish->getPositionX() + 400, visibleSize.height/2 - 300);
bezier.endPosition = ccp(m_fish->getPositionX() + 600,visibleSize.height/2);

bezier1.controlPoint_1 = ccp(m_fish->getPositionX() + 800, visibleSize.height/2 + 300);
bezier1.controlPoint_2 = ccp(m_fish->getPositionX() + 1000, visibleSize.height/2 - 300);
bezier1.endPosition = ccp(m_fish->getPositionX() + 1200,visibleSize.height/2);


bezierForward = CCBezierTo::create(6, bezier);
nextBezier = CCBezierTo::create (6,bezier1);

m_fish->runAction(CCSequence::create( bezierForward, nextBezier, NULL));

How can I make my sprite rotate while moving it with CCBezierTo?

  • \$\begingroup\$ Thanks i solved, i use this code: CGPoint oldpos = [[self target] position]; [super update:time]; CGPoint newpos = [[self target] position]; float angle = atan2(-newpos.y + oldpos.y, newpos.x - oldpos.x) * 180 / M_PI; angle += 90; // my sprites start pointing up [[self target] setRotation:angle]; \$\endgroup\$

i found a solution on this site. Use this very useful code: 

 CGPoint oldpos = [[self target] position];
    [super update:time];
    CGPoint newpos = [[self target] position];
    float angle = atan2(-newpos.y + oldpos.y, newpos.x - oldpos.x) * 180 / M_PI;
    angle += 90; // my sprites start pointing up
    [[self target] setRotation:angle];

and sprite can rotate when move with ccbezierTo.
