Sets the blending mode.
Contents
Function
Synopsis
love.graphics.setBlendMode( mode, alphamode )
Arguments
BlendMode mode- The blend mode to use.
Available since LÖVE 0.10.0
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.
Examples
function love.load()
love.graphics.setBackgroundColor(.21, .67, .97)
end
function love.draw()
love.graphics.setBlendMode("alpha") -- Default blend mode.
love.graphics.setColor(.90, .17, .48)
love.graphics.rectangle("fill", 50,50, 100,100)
love.graphics.setColor(.04, .39, .90)
love.graphics.setBlendMode("multiply", "premultiplied")
love.graphics.rectangle("fill", 75,75, 125,125)
end
