两个精灵调用同一个动作

两个精灵调用同一个动作需要注意：

-(void) onEnter
{
    [super onEnter];
    
    [self centerSprites:3];
        
    id actionTo = [CCRotateTo actionWithDuration: 2 angle:45];
    id actionTo0 = [CCRotateTo actionWithDuration:2  angle:0];
    [tamara runAction: [CCSequence actions:actionTo, actionTo0, nil]];

    id actionBy = [CCRotateBy actionWithDuration:2  angle: 360];
    id actionByBack = [actionBy reverse];
    [grossini runAction: [CCSequence actions:actionBy, actionByBack, nil]];

    [kathia runAction: [CCSequence actions:[[actionBy copy]autorelease], [[actionByBack copy]autorelease], nil]];
    
}

需要注意复制动作

 

但是对于贝塞尔曲线动作则不需要复制

 

-(void) onEnter
{
    [super onEnter];
    
    CGSize s = [[CCDirector sharedDirector] winSize];
    
    //
    // startPosition can be any coordinate, but since the movement
    // is relative to the Bezier curve, make it (0,0)
    //
    
    // sprite 1
    ccBezierConfig bezier;
    bezier.controlPoint_1 = ccp(0, s.height/2);
    bezier.controlPoint_2 = ccp(300, -s.height/2);
    bezier.endPosition = ccp(300,100);
    
    id bezierForward = [CCBezierBy actionWithDuration:3 bezier:bezier];
    id bezierBack = [bezierForward reverse];    
    id seq = [CCSequence actions: bezierForward, bezierBack, nil];
    id rep = [CCRepeatForever actionWithAction:seq];
    
    // sprite 2
    //[tamara setPosition:ccp(80,160)];
    ccBezierConfig bezier2;
    bezier2.controlPoint_1 = ccp(100, s.height/2);
    bezier2.controlPoint_2 = ccp(200, -s.height/2);
    bezier2.endPosition = ccp(240,160);
    
    id place1 = [CCPlace actionWithPosition:ccp(80,160)];
    id bezierTo1 = [CCBezierTo actionWithDuration:2 bezier:bezier2];    
    [tamara runAction:[CCSequence actions: place1, bezierTo1, nil]];
    
    // sprite 3
    //[kathia setPosition:ccp(400,160)];
    id place2 = [CCPlace actionWithPosition:ccp(400,160)];
    id bezierTo2 = [CCBezierTo actionWithDuration:2 bezier:bezier2];
    [kathia runAction:[CCSequence actions: place2, bezierTo2, nil]];
    
    [grossini runAction: rep];
    //[tamara runAction:bezierTo1];
    //[kathia runAction:bezierTo2];
    
}
