Question

我使用分辨率1000x1000初始化引擎并希望将整个场景保存在文件中。如果我使用ScreenCapture类截图，图片的最大分辨率是800x480（因为我的设备（htc欲望）是800x480，并且不可能有更多像素来自屏幕）。但场景更大，也许有办法迭代场景中的所有像素并保存1000x1000图片？

我尝试了以下代码来保存RenderTexture中的图片：

@Override
public Engine onCreateEngine(EngineOptions pEngineOptions)
{
        return new Engine(pEngineOptions) {

            private boolean mRenderTextureInitialized;

            int r[];

            private  RenderTexture mRenderTextures;

            @Override
            public void onDrawFrame(final GLState pGLState) throws InterruptedException {
                final boolean firstFrame = !this.mRenderTextureInitialized;

                if(firstFrame) {
                    this.initRenderTextures(pGLState);
                    this.mRenderTextureInitialized = true;
                }
                this.mRenderTextures.begin(pGLState);

                super.onDrawFrame(pGLState);

                this.mRenderTextures.end(pGLState);

                if (needToSave)
                {
                    needToSave = false;
                    final String location = SAVED_PATH + "/Screen_" + System.currentTimeMillis() + ".png";
                    FSHelper.saveBitmapToFile(mRenderTextures.getBitmap(pGLState), location);
                }


            }

            private void initRenderTextures(final GLState pGLState) {
                final int surfaceWidth = this.mCamera.getSurfaceWidth();
                final int surfaceHeight = this.mCamera.getSurfaceHeight();


                    this.mRenderTextures = new RenderTexture(EnchantActivity.this.getTextureManager(), surfaceWidth, surfaceHeight);
                    this.mRenderTextures.init(pGLState);

                }

        };
}

您无法截取未呈现的内容！

但是当使用GLES2分支时，您可以将场景渲染为RenderTexture，它可以是任意大小的。此示例应该有所帮助：https://github.com/nicolasgramlich/AndEngineExamples/blob/GLES2/src/org/andengine/examples/MotionStreakExample.java
