[Cocos2d-x game engine development notes (17)] Achieve the tail effect of Sports

Original article, reproduced please indicate the source: http://blog.csdn.net/zhy_cheng/article/details/8434598

To make the moving object have a tail effect, you can use ccmotionstreak.

Here I use [Cocos2d-x game engine development Note (12)] particle system to achieve user interaction with the example of special effects, making the effect more cool.

Add the following to the header file:

Ccmotionstreak * strike;

Then add the following code to the init function:

Strike = ccmotionstreak: streakwithfade (1.0f, // The duration of the tail: 16366f, // the size of the tail: 16366f, // the size of the image: ccc3 (255,255, 0 ), // color "sprite.png" // used image); addchild (Strike, 1); strike-> setposition (CCP (240,160 ));

Then change the position in the cctouchmoved function.

Strike-> setposition (ptouch-> getlocation ());

Set the position in the cctouchbegan Function

Strike-> setposition (ptouch-> getlocation ());

Okay, I'm done. The following figure shows the running effect on the G2 mobile phone of my Jiayu.
