Retain screen without love.draw and canvas

Post by utunnels »

It seems even if I copy love.run from source code and remove love.graphics.clear from code, the screen still loses after I minimize the window.

Yes, GPUs and drivers and window managers are not designed to be used like that.

OK.
I just thought it sometimes has thousands of print call since it a text and grid based interface.

Roguelike, eh? Create a spritesheet with letters in it, and use spritebatch to render the map.

Besides spritebatches, canvas is a natural and efficient solution to the problem. The main downside is, that canvases are not supported by all types of graphics cards. If you want to be sure that everyone can run your game, try to avoid canvases or make it optional.
