示例1: reverse

CCActionInterval* CCCardinalSplineBy::reverse()
{
    CCPointArray *copyConfig = (CCPointArray*)m_pPoints->copy();
	
	//
	// convert "absolutes" to "diffs"
	//
    CCPoint p = copyConfig->getControlPointAtIndex(0);
    for (unsigned int i = 1; i < copyConfig->count(); ++i)
    {
        CCPoint current = copyConfig->getControlPointAtIndex(i);
        CCPoint diff = ccpSub(current, p);
        copyConfig->replaceControlPoint(diff, i);
        
        p = current;
    }
	
	
	// convert to "diffs" to "reverse absolute"
	
    CCPointArray *pReverse = copyConfig->reverse();
    copyConfig->release();
	
	// 1st element (which should be 0,0) should be here too
    
    p = pReverse->getControlPointAtIndex(pReverse->count()-1);
    pReverse->removeControlPointAtIndex(pReverse->count()-1);
    
    p = ccpNeg(p);
    pReverse->insertControlPoint(p, 0);
    
    for (unsigned int i = 1; i < pReverse->count(); ++i)
    {
        CCPoint current = pReverse->getControlPointAtIndex(i);
        current = ccpNeg(current);
        CCPoint abs = ccpAdd(current, p);
        pReverse->replaceControlPoint(abs, i);
