Why is there sleep(0.001) in default love.run()?

Post by fuxoft »

Why is there the following line in the default love.run() function?

Code: Select all

if love.timer then love.timer.sleep(0.001) end
Is it just a failsafe to prevent the 100% CPU load when someone pumps new frames without vsync, as fast as possible? Or does it have more complex purpose?

Do you recognise when the world won't stop for you? Or when the days don't care what you've got to do? When the weight's too tough to lift up, what do you? Don't let them choose for you, that's on you.

Yes, that's it. A very simple way to prevent LÖVE from wasting all the CPU cycles and it's in love.run so lovers can easily remove it, if they want to.
Shallow indentations.
