Cocos2dx：3.10+cocostudio多屏幕分辨率适配解决方案

1.设计分辨率

配资源使用的分辨率大小,是1334*750。

2.屏幕分辨率

实际上用户屏幕的分辨率大小，不确定。

这里是实现代码：

}

//1、先适配layout层到屏幕大小

    node->setScaleX(nodeX);
    node->setScaleY(nodeY);
}

//屏幕宽、高分别和设计分辨率宽、高计算缩放因子，取较(大)者作为宽、高的缩放因子。
//适用于控件的缩放
void FixUIUtils::setScaleMax(Node *node){
    auto nodeX = node->getScaleX();

    log("setScaleMax nodeX = %f * nodeX = %f \n",nodeX, nodeY);

    nodeX = nodeX * maxScale;
    nodeY = nodeY * maxScale;
    log("setScaleMax nodeX = %f * nodeX = %f \n",nodeX, nodeY);

    node->setScaleX(nodeX);
    node->setScaleY(nodeY);
}

//屏幕宽、高分别和设计分辨率宽、高计算缩放因子，取较(小)者作为宽、高的缩放因子。
//适用于背景的缩放
void FixUIUtils::setScaleMin(Node *node){
    auto nodeX = node->getScaleX();

    log("setScaleMin nodeX = %f * nodeX = %f \n",nodeX, nodeY);

    node->setScaleX(nodeX);
    node->setScaleY(nodeY);
}


void FixUIUtils::setRootNodewithFIXED(Node* node){
    auto moveX = (designSize.width - screenSize.width);
    auto moveY = (designSize.height - screenSize.height);
    node->setPosition(Point(-moveX ,-moveY));
}

void FixUIUtils::fixScene(Node* node){
    fixUI(node);
    FixUIUtils::setRootNodewithFIXED(node);
}


void FixUIUtils::fixUI(Node* node){
    Vector ChildrenList = node->getChildren();

    for (Node* child: ChildrenList) {
        log("fixUI nodeX = %d \n",child->getTag());
        FixUIUtils::setScaleMin(child);
    }
    
}

调用：

//加载Cocos Studio编辑好的资源
    auto rootNode = CSLoader::createNode("test.csb");
    FixUIUtils::init();
    FixUIUtils::setFixScale(rootNode);
    FixUIUtils::fixScene(rootNode);
    this->addChild(rootNode);
