Optimizations for OPPO devices

Note: This document applies to Cocos2d-x 3.17.2 and later only. Cocos2d-x has a few optimizations for OPPO devices. These optimizations will only work on OPPO devices (specially Reno devices).

What's optimized

There are two places that are optimized:

• loading a scene
• engine's internal shaders compiling

Loading scene optimizations start when Scene is created, and ended in Scene::onEnter() and therefore you should create resources between them.

Invoke optimization codes manually

The application knows where more power is needed, better than the engine knows. You can invoke this API to get more power when needed. You can invoke this API in both C++ or Java.

Example usage in C++

// Notify device that an event happends, such as start loading a scene.
// It is available after v3.17.2.
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    DataManager::setOptimise(const string&, const string&);
#end if

// Scene loading starts, need more power.
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    DataManager::onSceneLoaderBegin();
#end if

// Scene loading ends.
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    DataManager::onSceneLoaderEnd();
#end if

// Shader compiling begin, need more power.
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    DataManager::onShaderLoaderBegin();
#end if

// Shader compiling ends.
#if CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID
    DataManager::onShaderLoaderEnd();
#end if

Example usage in Java:

Cocos2dxDataManager::setOptimise(String thing, float value);

Table Of Values

After v3.17.2, the type of value changed from float to string to make it more usable.
