Errors: Cocos2d-x v4.0 在xCode 里出现Reference to non-static member function must be called

this->schedule(schedule_selector(GamePlaying::updateGame),0.01f);

auto staticUpdatePtr = static_cast(&GamePlaying::updateGame);

this->schedule(staticUpdatePtr,0.01f);

Game Codes: Cocos2d-x 贝塞尔曲线在游戏应用

Examples:

ccBezierConfig tr0;
tr0.endPosition=ccp(280, 240);
tr0.controlPoint_1=ccp(40, 400);
tr0.controlPoint_2=ccp(280, 80);
CCActionInterval* bezierForward = CCBezierBy::create(1.f, tr0);

Game Codes: Cocos2d-x 计算两点之间的夹角

实现一个发射子弹的方法 子弹的朝向的角度会根据发射的终点和起点变化。
auto sp = Sprite::create("bullet.png");
Vec2 endPos = Vec2(200, 500);
Vec2 startPos = Vec2(100, 50);
auto move = MoveTo::create(5, endVec2);
sp->runAction(move);
//计算角度
Vec2 dis = endPos - startPos;
sp->setRotation(Vec2(dis.y, dis.x).getAngle() / 3.14f * 180);//一定注意x和y参数是倒过来的
//这样发射出去的子弹就会朝向终点了

COCOS2DX3.0的3种触摸响应机制

第一种是采用函数回调，主要是用于MenuItem

1. // a selector callback
2. void menuCloseCallback(Object* pSender);
4. auto closeItem = MenuItemImage::create("CloseNormal.png","CloseSelected.png",
5. CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
7. void HelloWorld::menuCloseCallback(Object* pSender)
8. {
9. Director::getInstance()->end();
11. #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
12. exit(0);
13. #endif
14. }

 

第二种方法TouchEvent响应

1. //声明
2. void touchButton(Object* object,TouchEventType type);
3. //挂接到控件上
4. uiButton->addTouchEventListener(this,toucheventselector(HelloWorld::touchButton));
5. //实现
6. void HelloWorld::touchButton(Object* object,TouchEventType type)
7. {
8. LabelTTF* label;
9. switch (type)
10. {
11. case TouchEventType::TOUCH_EVENT_BEGAN:
12. label = static_cast<LabelTTF*>(getChildByTag(11));
13. label->setString("按下按钮");
14. break;
15. case TouchEventType::TOUCH_EVENT_MOVED:
16. label = static_cast<LabelTTF*>(getChildByTag(11));
17. label->setString("按下按钮移动");
18. break;
19. case TouchEventType::TOUCH_EVENT_ENDED:
20. label = static_cast<LabelTTF*>(getChildByTag(11));
21. label->setString("放开按钮");
22. break;
23. case TouchEventType::TOUCH_EVENT_CANCELED:
24. label = static_cast<LabelTTF*>(getChildByTag(11));
25. label->setString("取消点击");
26. break;
27. default:
28. break;
29. }
30. }

 

第三种 触摸监听绑定

1. auto listener1 = EventListenerTouchOneByOne::create();//创建一个触摸监听
2. listener1->setSwallowTouches(true);//设置是否想下传递触摸
4. Rect rect = Rect(qipanPoint.x,qipanPoint.y
5. ,qipanSize.width,qipanSize.height);
6. //3.0 后可以直接在touchBegan后添加它的实现代码，而不用特意去写一个touchBegan的函数
7. listener1->onTouchBegan = [rect,this](Touch* touch, Event* event){ //[]中间的是传入的参数
8. auto target = static_cast<Sprite*>(event->getCurrentTarget());//获取的当前触摸的目标
10. Point locationInNode = target->convertToNodeSpace(touch->getLocation());
11. Size s = target->getContentSize();
13. if (rect.containsPoint(locationInNode))//判断触摸点是否在目标的范围内
14. { //以下是我自定义的一些操作
15. //创建锁定精灵
16. auto lockSprite = Sprite::create("lock.png");
17. lockSprite->setPosition(GetQiziPoint(locationInNode,rect));
18. lockSprite->setTag(99);
19. this->addChild(lockSprite);
20. return true;
21. }else
22. return false;
23. };
24. //拖动精灵移动
25. listener1->onTouchMoved = [rect,this](Touch* touch, Event* event){
26. auto target = static_cast<Sprite*>(event->getCurrentTarget());//获取的当前触摸的目标
27. Point locationInNode = target->convertToNodeSpace(touch->getLocation());
28. Size s = target->getContentSize();
30. if (rect.containsPoint(locationInNode))//判断触摸点是否在目标的范围内
31. {
32. //锁定精灵移动
33. Sprite *lockSprite = (Sprite*)this->getChildByTag(99);
34. lockSprite->setPosition(GetQiziPoint(locationInNode,rect));
35. }
36. };
38. listener1->onTouchEnded = [=](Touch* touch, Event* event){ // =在c++11里面代表这个lambda表达式中能使用外面的变量
39. this->removeChildByTag(99);//移除锁定精灵
40. };
41. //将触摸监听添加到eventDispacher中去
42. _eventDispatcher->addEventListenerWithSceneGraphPriority(listener1 ,layer);

搭建开发环境 - Android 平台

https://docs.cocos.com/cocos2d-x/manual/zh/installation/Android-Studio.html

 

Android Studio更新gradle等软件

导入项目

app/jni/application.mk 修改为 APP_STL := c++_static

gradle.properties

PROP_COMPILE_SDK_VERSION=28

PROP_MIN_SDK_VERSION=14

PROP_TARGET_SDK_VERSION=24

PROP_APP_PLATFORM=14

PROP_APP_ABI=armeabi-v7a

app/build.gradle

注释掉 //arguments 'NDK_TOOLCHAIN_VERSION=4.9'

修改buildToolsVersion "28.0.3"

proj.android-studio/build.gradle修改

allprojects {

repositories {

jcenter()

+ google()

}

}

SDKBOX

安装时需要连接VPN，否则可能报SSL CERTIFICATE_VERIFY_FAILED相关的错误

安装sdk时提示路径错误，先在proj.android-studio目录下创建临时文件/夹，安装完成后再移到proj.android-studio/app目录下

[app/*.iml文件将app/sdkbox等3个目录改为app/jni/sdkbox]

修改AppActivity.java

+ import android.content.Intent;

+ import com.sdkbox.plugin.SDKBox;

protected void onCreate(Bundle savedInstanceState) {

...

+ SDKBox.init(this);

}

添加

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if(!SDKBox.onActivityResult(requestCode, resultCode, data)) {

super.onActivityResult(requestCode, resultCode, data);

}

}

@Override

protected void onStart() {

super.onStart();

SDKBox.onStart();

}

@Override

protected void onStop() {

super.onStop();

SDKBox.onStop();

}

@Override

protected void onResume() {

super.onResume();

SDKBox.onResume();

}

@Override

protected void onPause() {

super.onPause();

SDKBox.onPause();

}

@Override

public void onBackPressed() {

if(!SDKBox.onBackPressed()) {

super.onBackPressed();

}

}

 

Android.mk添加

LOCAL_WHOLE_STATIC_LIBRARIES += PluginAdMob

sdkbox \

PluginSdkboxAds

文件末尾添加（必须末尾、全路径，原因待查）

include absolute_root_path\proj.android-studio\app\jni\CocosAndroid.mk

 

CocosAndroid.mk中包含的重要部分

LOCAL_PATH := $(call my-dir)

$(call import-add-path, $(LOCAL_PATH))

$(call import-module, sdkbox)

$(call import-module, PluginSdkboxAds)

$(call import-module, PluginAdMob)

 

TroubleShooting

Admob: proxy is null可能是sdkbox_config.json格式错误，多检查日志里的error，如果json格式错误会提示
