You could use an black sprite that covers the screen that you fade in and out the get an night effect.
Simply so do you set that sprite completely transparent during daytime and fade it in to get an night effect.

I know the way which you said.but canvas is advanced.because it can use unregular image to perform night effect.

canvas : combine two image into one image with some calculation .
for example, I can dig a hole from a image. then I can use the image to cover something. it's very useful.

is it difficult to come out for agk?

If i remember it right so is canvas a part of open gls true 2d functions that is pretty slow?
And dosent work that well together with open gls 3d functions, that the agk use with an fixed camera to get the illusion of 2d.
I think they skipped the open gl native 2d functions as they are obselete today?

Most users use its 3d functions to get an 2d look and feel.

Having the option of combining 2 images to make sfx, like an empty hole inside an image would be great.

However I don't know if such functions will come in AppGameKit any soon.

Would be great if there's an OGL-comptable sdk with such advanced features, and someone wraps up the functions to use with AppGameKit sprites & images.
