Synopsis
love.graphics.setBlendMode( mode, alphamode )
Arguments
BlendMode mode
- The blend mode to use.
BlendAlphaMode alphamode ("alphamultiply")
- What to do with the alpha of drawn objects when blending.
Returns
Nothing.
Notes
The default "alphamultiply" alpha mode should normally be preferred except when drawing content with pre-multiplied alpha. If content is drawn to a Canvas using the "alphamultiply" mode, the Canvas texture will have pre-multiplied alpha afterwards, so the "premultiplied" alpha mode should generally be used when drawing a Canvas to the screen.
Example
function love.load()
love.graphics.setBackgroundColor(54/255, 172/255, 248/255)
end
function love.draw()
love.graphics.setBlendMode("alpha") --Default blend mode
love.graphics.setColor(230/255, 44/255, 123/255)
love.graphics.rectangle("fill", 50, 50, 100, 100)
love.graphics.setColor(12/255, 100/255, 230/255)
love.graphics.setBlendMode("multiply", "premultiplied")
love.graphics.rectangle("fill", 75, 75, 125, 125)
end
