Use this method to finish batch drawing to this Render Texture.
Never call this method without first calling
It is faster than calling
draw, but you must be very careful to manage the
flow of code and remember to call
endDraw(). If you don't need to draw large
numbers of objects it's much safer and easier to use the
draw method instead.
The flow should be:
// Call once: RenderTexture.beginDraw(); // repeat n times: RenderTexture.batchDraw(); // or RenderTexture.batchDrawFrame(); // Call once: RenderTexture.endDraw();
Do not call any methods other than
endDraw once you
have started a batch. Also, be very careful not to destroy this Render Texture while the
batch is still open, or call
Draws all objects in this batch using a blend mode of ERASE. This has the effect of erasing any filled pixels in the objects being drawn.
