SneakyJoystick

SneakyJoystick is a library that provides a ‘joystick-like’ features to a layer in Cocos2d-x. The library support:

  • Joystick Thumb
  • Joystick D-Pad
  • Regular Buttons
  • Holdable Buttons
  • Toggleable Buttons

The project was originally created CJ Hanson (https://github.com/cjhanson). This is a port for Cocos2d-x version 2.2.1 and 3.0rc0, and now 3.9 cocos studio projects

How to Use the Library

The best way to use the library is to create a JoystickLayer, and then add that layer to your Game Scene.

This is an example on how to create a Joystick Thumb

How to implement on my game:

In case the HelloWorld i.e

On HelloWorld.h

Add

#include "SneakyButton.h"
#include "SneakyButtonSkinnedBase.h"
#include "SneakyJoystickSkinnedBase.h"

Below
public:

SneakyJoystick *leftJoystick;
SneakyButton *jumpBtn;

HelloWorld.cpp
Add

Rect joystickBaseDimensions;
joystickBaseDimensions = Rect(0, 0, 160.0f, 160.0f);

Point joystickBasePosition;
joystickBasePosition = Vec2(visibleSize.width * 0.2f, visibleSize.height*0.2f);

SneakyJoystickSkinnedBase *joystickBase = new SneakyJoystickSkinnedBase();
joystickBase->init();
joystickBase->setPosition(joystickBasePosition);
joystickBase->setBackgroundSprite(Sprite::create("res/joystick-back.png"));
joystickBase->setThumbSprite(Sprite::create("res/stick.png"));

SneakyJoystick *aJoystick = new SneakyJoystick();
aJoystick->initWithRect(joystickBaseDimensions);

aJoystick->autorelease();
joystickBase->setJoystick(aJoystick);
joystickBase->setPosition(joystickBasePosition);

leftJoystick = joystickBase->getJoystick();
leftJoystick->retain();
this->addChild(joystickBase);

And for button

Rect jumpButtonDimensions = Rect(0, 0, 64.0f, 64.0f);
Point jumpButtonPosition;
jumpButtonPosition = Vec2(visibleSize.width * 0.9f, visibleSize.height * 0.2f);

SneakyButtonSkinnedBase *jumpButtonBase = new SneakyButtonSkinnedBase();
jumpButtonBase->init();
jumpButtonBase->setPosition(jumpButtonPosition);

jumpButtonBase->setDefaultSprite(Sprite::create("res/btn-attack.png"));
jumpButtonBase->setActivatedSprite(Sprite::create("res/btn-attack-pressed.png"));
jumpButtonBase->setDisabledSprite(Sprite::create("res/btn-attack-pressed.png"));
jumpButtonBase->setPressSprite(Sprite::create("res/btn-attack-pressed.png"));

SneakyButton *ajumpButton = new SneakyButton();
ajumpButton->initWithRect(jumpButtonDimensions);
ajumpButton->autorelease();

jumpButtonBase->setButton(ajumpButton);
jumpButtonBase->setPosition(jumpButtonPosition);

jumpBtn = jumpButtonBase->getSbutton();
jumpBtn->retain();
this->addChild(jumpButtonBase);

And finally on update example:

void HelloWorldScene::update(float dt){

    this->setViewPointCenter(_everboy->getPosition());

    if(leftJoystick->getVelocity().x > 0){
        everboyBody->setVelocity( Vect( 200, 0 ) );
    }
    if(leftJoystick->getVelocity().x < 0){
        everboyBody->setVelocity( Vect( -200, 0 ) );
    }
    if(leftJoystick->getVelocity().x == 0 ){
        everboyBody->setVelocity( Vect( 0, everboyBody->getWorld()->getGravity().y ) );
    }
    if(jumpBtn->getValue()){
        everboyBody->applyImpulse(Vec2(0, 200));
        everboyBody->setVelocity(Vec2(0,100));
    }
}

Done now you have your dPad or Joystick and your buttons.
