正确

var tmpShip3 = cc.Sprite.createWithSpriteFrameName("w1_1.png");            tmpShip3.setPosition(250,180);            this.addChild(tmpShip3);            var animFrames3 = []; //      将所有帧存入一个数组            for (var i=1;i<=4;i++) {                //采用循环添加动画的每一帧                var strPngName3 = "w1_" + i + ".png";                var frame3 =cc.SpriteFrameCache.getInstance().getSpriteFrame(strPngName3);                if (frame3) {                    animFrames3.push(frame3);                }            }            var animation3 = cc.Animation.create(animFrames3, 0.01);            tmpShip3.runAction(cc.RepeatForever.create(cc.Animate.create(animation3)));            tmpShip3.runAction(cc.MoveTo.create(3, cc.p(250 ,winSize.height)));

 

 

无效

tmpShip3.runAction(                cc.Spawn.create(                    cc.RepeatForever(cc.Animate.create(animation3)),                    cc.MoveTo.create(3, cc.p(250 ,winSize.height))                )            );

有效，只动一次

tmpShip3.runAction(                cc.Spawn.create(                    cc.Animate.create(animation3),                    cc.MoveTo.create(3, cc.p(250 ,winSize.height))                )            );
