The particle system I am using seems to freeze up momentarily every few seconds - I don't know whether it freezes the whole game or not, but I'm assuming that to be the case. EDIT: It seems to stop rendering, and the particle emitter stops emitting, but when it unfreezes, the particles that have already been emitted had continued moving - which seems to suggest that it's updating particles that have been emitted, but not emitting any new ones. The window still shows the last rendered frame, not blankness.
If people could please see if they get the same problem, and whether they know what could cause it, it would be very useful.
The code from my main.lua file:
Code: Select all
function love.load() drp = love.graphics.newImage("droplet.png") sys = love.graphics.newParticleSystem(drp,1000) sys:setPosition(400,300) sys:setGravity(100,150) sys:setSpread(math.rad(30)) sys:setEmissionRate(100) --this may be causing problems, try increasing it if you don't get the wierd freezing sys:setLifetime(-1) sys:setParticleLife(4,5) --this too sys:setSpeed(200,300) sys:start() end function love.update(dt) sys:setSize(math.random()) sys:setRotation(math.random()) sys:setDirection(math.atan2(love.mouse.getY()-300,love.mouse.getX()-400)) sys:update(dt) end function love.draw() love.graphics.draw(sys) end
