Is it possible to put a black opaque rectangle over my game screen and then change transparency on some pixels?
For example I have black rectangle on screen represented by 1
1111111111111111111111
1111111111111111111111
1111111111111111111111
1111111111111111111111
1111111111111111111111
1111111111111111111111
1111111111111111111111
and then I would like to make several pixels transparent represented by 0
1111111111111111111111
1111100000000000011111
1111111100000011111111
1111111111001111111111
1111111100000011111111
1111100000000000011111
1111111111111111111111
Would that be possible using blend modes?
P.S. I'm using version 0.8.0. of Love2D
