Source:setRelative

Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Sets whether the Source's position, velocity, direction, and cone angles are relative to the listener, or absolute.

By default, all sources are absolute and therefore relative to the origin of love's coordinate system [0, 0, 0]. Only absolute sources are affected by the position of the listener.

Function

Synopsis

Source:setRelative( enable )

Arguments

boolean enable ("false")
True to make the position, velocity, direction and cone angles relative to the listener, false to make them absolute.

Returns

Nothing.

Absolute Source Demonstration

This example demonstrates how an absolute source is affected by the position of the listener.

-- The position of the listener.
local x, y, z;

-- The sound to play.
local snd;

function love.load()
    snd = love.audio.newSource('example.ogg', 'static')
    snd:setLooping(true);
    snd:play();

    -- Set the position of the listener and the source to the middle of the screen.
    x = love.graphics.getWidth() * 0.5;
    y = love.graphics.getHeight() * 0.5;
    z = 0;
    love.audio.setPosition(x, y, z);
    snd:setPosition(x, y, z);
end

-- Move the listener to the left ('a') or to the right ('d').
function love.keypressed(key)
    if key == 'a' then
        x = x - 1;
        love.audio.setPosition(x, y, z);
    elseif key == 'd' then
        x = x + 1;
        love.audio.setPosition(x, y, z);
    end
end
