love.graphics.setBlendMode

Sets the blending mode.

Function

Synopsis

love.graphics.setBlendMode( mode )

Arguments

BlendMode mode
The blend mode to use.

Returns

Nothing.

Function

Available since LÖVE 0.10.0
This variant is not supported in earlier versions.

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, 172, 248)
end
 
function love.draw()
	love.graphics.setBlendMode("alpha") --Default blend mode
	love.graphics.setColor(230, 44, 123)
	love.graphics.rectangle("fill", 50, 50, 100, 100)
 
	love.graphics.setColor(12, 100, 230)
	love.graphics.setBlendMode("multiply")
	love.graphics.rectangle("fill", 75, 75, 125, 125)
end
