Changing the brightness of a graphics.draw object?

[Calahagus]

Just as the title says. Is there a function that I can use to change how bright an image I draw is, or do I have to do that outside of LOVE?

To do that within love you'd need a shader i think.

Well, you could make a function that convert HSL into RGB.

If you just want to darken it, you can use setColor with a gray color.

You can use the 'combine' color mode. See love.graphics.setColorMode and ColorMode. If I remember correctly, it does something like this.

Code: Select all

resulting color = color of texture + (color set with setColor - 128)

So setting a color of (128, 128, 128) means no change. Values above that get added, values below get subtracted.

Sadly, this function will be removed in the next version of LÖVE as we move on the the wondrous world of shaders.

This worked perfectly, should have thought of it myself. Thanks!
