2. CCJoystick class (the latest version already supports rubbing, download link http://code.google.com/p/ccjoystick/downloads/list)

CCJoyStick is a Cocos2d-based joystick class, a few lines of code can add a powerful analog joystick to your game. And the latest version already supports rocking tricks to meet the needs of combat game developers.

Based on this class, many rocker effects can be expanded independently, such as 360-degree mode and 8-direction mode. The method of use is as follows:

/ / create a rocker

Myjoystick= [CCJoyStick initWithBallRadius:25 MoveAreaRadius:65 isFollowTouch:NO isCanVisible:YES isAutoHide:NO hasAnimation:YES]; / / BallRadius is to simulate the radius of the rocker ball, and MoveAreaRadius is the radius of the range in which the rocker ball can move. IsFollowTouch means whether to follow the reference position of the rocker to touch coordinates, whether isCanVisible is visible, whether isAutoHide is automatically hidden (touchend is hidden), and whether hasAnimation shows rocker reset animation.

/ / add skin

[myjoystick setBallTexture:@ "Ball.png"]; / / optional. If not set, the joystick ball cannot be seen.

[myjoystick setDockTexture:@ "Dock.png"]; / / optional. If not set, the base cannot be seen.

[myjoystick setStickTexture:@ "Stick.jpg"]; / / optional. If not set, the connecting rod cannot be seen.

[myjoystick setHitAreaWithRadius:100]; / / the joystick activation area is the reference coordinate radius, which defaults to another method. Set the screen rectangle area to the activation area setHitAreaWithRect.

Myjoystick.position=ccp (100100)

Myjoystick.delegate=self

[self addChild:myjoystick]

The joystick class contains three events:

1.-(void) onCCJoyStickUpdate: (CCNode*) sender Angle: (float) angle Direction: (CGPoint) direction Power: (float) power;//angle is used to control character orientation, direction is used to set moving coordinates, and power is used to control speed.

2.-(void) onCCJoyStickActivated: (CCNode*) sender

3.-(void) onCCJoyStickDeactivated: (CCNode*) sender

The implementation code is as follows:

[glView setMultipleTouchEnabled:YES]; whether it is set to YES. When I first started, I didn't set it up and checked it for a long time. Hey, there's a la carte.
