Available since LÖVE 0.8.0 and removed in LÖVE 0.9.0
It has been renamed to love.graphics.setShader.


Sets or resets a PixelEffect as the current pixel effect. All drawing operations until the next love.graphics.setPixelEffect will be drawn using the PixelEffect object specified.

Function

Synopsis

love.graphics.setPixelEffect( pixeleffect )

Arguments

PixelEffect pixeleffect
The new pixel effect.

Returns

Nothing.

Notes

Sets the current pixel shader to a specified PixelEffect. All drawing operations until the next love.graphics.setPixelEffect will be drawn using the PixelEffect object specified.

Function

Synopsis

love.graphics.setPixelEffect( )

Arguments

None.

Returns

Nothing.

Notes

Disables pixel effects, allowing unfiltered drawing operations.

Examples

Drawing a rectangle using a pixel effect

function love.load()
    effect = love.graphics.newPixelEffect [[
        extern number time;
        vec4 effect(vec4 color, Image texture, vec2 texture_coords, vec2 pixel_coords)
        {
            return vec4((1.0+sin(time))/2.0, abs(cos(time)), abs(sin(time)), 1.0);
        }
    ]]
end

function love.draw()
    -- boring white
    love.graphics.setPixelEffect()
    love.graphics.rectangle('fill', 10,10,790,285)

    -- LOOK AT THE PRETTY COLORS!
    love.graphics.setPixelEffect(effect)
    love.graphics.rectangle('fill', 10,305,790,285)
end

local t = 0
function love.update(dt)
    t = t + dt
    effect:send("time", t)
end
