I used Windows task manager. I hope I did things correctlyNixola wrote:How did you measure RAM usage?
Well the algorithm is pretty simple. The issue might be that it's repeated 10000 times for each frame.slime wrote:It sounds like the low framerate is probably due to unoptimized usage of love.graphics functions rather than a RAM-related thing. If you post a .love or further describe what you're doing (graphics-wise) and what you want it to look like, we can hopefully provide some good performance-improving advice.
Code: Select all
function love.load()
line = 10000 -- number of lines
rd = math.pi / (line / 2)
n = 1
speed = 0.5
alpha = 5
dir = 0
end
function love.update(dt)
if love.keyboard.isDown("up") then
dir = 1
elseif love.keyboard.isDown("down") then
dir = -1
elseif love.keyboard.isDown(" ") then
dir = 0
end
if speed >= 0 then
if love.keyboard.isDown("w") then
speed = speed + dt
elseif love.keyboard.isDown("s") then
speed = speed - dt
end
else
speed = 0
end
n = n + speed * dir * dt
end
function love.draw()
love.graphics.setColor(255, 255, 255, 255)
love.graphics.print(n)
love.graphics.print(speed, 0, 15)
for k = 1, line do
if k % 3 == 1 then
love.graphics.setColor(255, 0, 0, alpha)
elseif k % 3 == 2 then
love.graphics.setColor(0, 255, 0, alpha)
elseif k % 3 == 0 then
love.graphics.setColor(0, 0, 255, alpha)
end
love.graphics.line(400 + 300 * math.sin(k * rd), 300 + 300 * math.cos(k * rd), 400 + 300 * math.sin(k * n * rd), 300 + 300 * math.cos(k * n * rd))
end
endNah, the "up" and "down" keys control whether n is increased or decreased by the speed. I should really move that to love.keypressed function.kikito wrote:Yes, those 10k draw calls certainly will slow things down.
It seems that you are changing the lines only when a key is pressed (the code handling this is a bit messy and I might be mistaken). If that's the case, I'd suggest drawing into a canvas - only updating it when a key is pressed (when speed is > 0). That way you would "pay the price" of drawing all those lines only when the speed is changed, not on every frame.
