There are a lot of animation effects in the project, most of which are implemented using action. Of course, you can also implement it yourself at each frame. The principle is basically the same.

1. Fast jitter between left and right using ccmoveto.

CCPoint pointL=pointBg;CCPoint pointR=pointBg;pointL.x-=3;pointR.x+=3;CCMoveTo* moveLeft=CCMoveTo::actionWithDuration(0.08, pointL);CCMoveTo* moveRight=CCMoveTo::actionWithDuration(0.08, pointR);CCFiniteTimeAction* action= CCSequence::actions(moveLeft,moveRight,NULL);CCActionInterval* actionShake=CCRepeatForever::actionWithAction((CCActionInterval*)action);skillBg->stopAllActions();skillBg->runAction(reSkillAnim);

Pointbg is the Sprite you need to shake left and right.

Ccmoveto is where to move, the parameter is the moving time, And the destination coordinate point. (Ccmoveby is the distance between the current position, which is slightly different .)

As mentioned above, ccsequence can be used as a queue for executing an action. If it encounters null, it will end.

Because it is to implement different left and right movements, I wrap the left and right movements into a ccrepeatforever action, which repeatedly plays this action.

2. ccjumpto jumps from one place to another.

CCJumpTo* mJumpTo = CCJumpTo::actionWithDuration(0.2f, mToPosition, 30.0f, 1);

The first parameter is the long jump time, the second parameter is the jump target point, the third parameter is the maximum jump height, and the fourth parameter is the number of hops.

3. ccdelaytime can be used as the pause duration. ,

CCDelayTime *waiting=CCDelayTime::actionWithDuration(0.2f);

Pause for 0.2 seconds.

4. Zoom in/out ccscaleto. (Difference between ccscaleby and how much to zoom in/out)

CCScaleTo* scale=CCScaleTo::actionWithDuration(0.5, 0.2);

The time of the first parameter, the second parameter scaling multiple, = 1 normal size,> 1 zoom in, <1 zoom out

5. ccrotateto rotation angle. Same as above. Angle: 0-360.

6. ccwaves and ccshaky3d

CCActionInterval* waves = CCWaves::actionWithWaves(5, 20, true, false, ccg(15,10), 5);CCActionInterval* shaky = CCShaky3D::actionWithRange(4, false, ccg(15,10), 5);

Ccwaves Wave Effect and ccshaky3d vibration effect. It is executed in full screen mode. You can see the specific effect when you run it.
