Title: Set a clip region to clip out screen tilemap
Post by: stevexu on December 06, 2013, 02:48:57 am

I have a long long tilemap,  the character walk along with it . The camera bind to the character so we can fellow the character. But i found the fps is low on some device. So I want to set a clip region to disable drawing things which out of screen.  So Is it possible? I found tk2dcamera have a "viewport clipping", but I don't known how to use it!

The tile map is partitioned and culled outside the viewport. You should try to work out what the bottleneck is before optimising - Its far more likely that you are overdrawing too much or script bound than limited by culled triangles.
