JavaANAppSurfaceView.surfaceCreated 不移除所有纹理的话, 会有问题吗? #38
Description
问题: JavaANAppSurfaceView.surfaceCreated 不移除所有纹理的话, 会有问题吗?
代码版本: 148d54077b1de819cf0958cc198b69ab97d67411
引擎代码: Java/Loon-Lite(PureJava)/LoonLiteCore, Java/Loon-Lite(PureJava)/LoonLiteJavaAN
例子项目: 使用这些目录里面的资源和代码Java/examples/assets, Java/examples/org, Java/Loon-Neo/src/assets, 创建了一个纯Java的Android Studio工程. 项目可以运行(拍拍手👏)!
但是, app 退到后台, 再返回前台, 图片不见了
但是, 文字还在, 按钮也在
打断点调试发现 JavaANAppSurfaceView.surfaceCreated 里面会清掉所有纹理.
public class JavaANAppSurfaceView ... {
@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
updatePpi();
start();
if (_game != null) {
// LSystem.resetTextureRes(_game); // 注释这行
if (_game.display() != null) {
_game.display().GL().update();
}
LSystem.d("Created Renderer View");
}
}
}注释以后, app 返回前台图片还在!!!
原例子代码的改动:
原例子有些代码在 LoonLiteCore 引擎里没有. 所以移除一些例子代码.
MultiScreenTest 里面移除了一些:
public class MultiScreenTest extends Screen {
// ...
@Override
public void onLoad() {
// ...

addScreen(page0[index++], new LMessageBoxTest());
