Creates a new ParticleSystem.
| This function can be slow if it is called repeatedly, such as from love.update or love.draw. If you need to use a specific resource often, create it once and store it somewhere it can be reused! |

Creation and usage of a particle system
You can use the löve logo as an example image.
function love.load()
local img = love.graphics.newImage('logo.png');
psystem = love.graphics.newParticleSystem(img, 32);
psystem:setParticleLifetime(2, 5); -- Particles live at least 2s and at most 5s.
psystem:setEmissionRate(5);
psystem:setSizeVariation(1);
psystem:setLinearAcceleration(-20, -20, 20, 20); -- Random movement in all directions.
psystem:setColors(255, 255, 255, 255, 255, 255, 255, 0); -- Fade to black.
end
function love.draw()
-- Draw the particle system at the center of the game window.
love.graphics.draw(psystem, love.graphics.getWidth() * 0.5, love.graphics.getHeight() * 0.5);
end
function love.update(dt)
psystem:update(dt);
end
local img = love.graphics.newImage('logo.png');
psystem = love.graphics.newParticleSystem(img, 32);
psystem:setParticleLifetime(2, 5); -- Particles live at least 2s and at most 5s.
psystem:setEmissionRate(5);
psystem:setSizeVariation(1);
psystem:setLinearAcceleration(-20, -20, 20, 20); -- Random movement in all directions.
psystem:setColors(255, 255, 255, 255, 255, 255, 255, 0); -- Fade to black.
end
function love.draw()
-- Draw the particle system at the center of the game window.
love.graphics.draw(psystem, love.graphics.getWidth() * 0.5, love.graphics.getHeight() * 0.5);
end
function love.update(dt)
