cc.RepeatForever和cc.Spawn冲突

正确

            var tmpShip3 = cc.Sprite.createWithSpriteFrameName("w1_1.png");
            tmpShip3.setPosition(,);
            this.addChild(tmpShip3);
 
            var animFrames3 = []; //      将所有帧存入一个数组
            for (var i=;i<=;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(, cc.p( ,winSize.height)));

无效

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

有效，只动一次

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