Big loop cycle

VictorFR

Hello comunity! Anybody try create game with very much objects? if i create cycle like 100 objects it work good but if i create cycle with 2000 objevts its work slowly/ I try use coroutines but i still don't understand it is possible create much object in game? like 20000 for example/
PS
sorry for my english

Hi @VictorFR - We like to help, but we need to see some code (so we know what objects you are using, and how you are drawing them)

PS there is no need to apologise for your English (I'm sure I can't speak your language at all!). Just do your best and we will try to understand.

i have very symple code function now: Ok i will send code today, now i can't (

@VictorFR You can draw 20,000 objects (mesh items), but depending on what size they are and what they're doing will affect the FPS. For instance, drawing 20,000 mesh items at different sizes runs at these FPS on an iPad Air.

EDIT: The positions of these items were calculated only once. If the positions don't change, an image can be created and drawn at near 60 FPS. But a lot is going to depend on what you want to do with the objects you draw.

FPS 59.7   size 2x2
    59.6        5x5
    59.4       10x10
    30         20x20
    11.5       50x50

Here's an example of drawing 20,000 (size 5x5) objects at random screen positions at 19.1 FPS on my iPad Air.

displayMode(FULLSCREEN)

function setup()
    fill(255)
    fps=60
end

function draw()
    background(40, 40, 50)
    m=nil
    collectgarbage()
    m=mesh()
    for z=1,20000 do
        m:addRect(math.random(WIDTH),math.random(HEIGHT),5,5)
        m:setRectColor(z,0,100,100,255)
    end
    m:draw()
    fps=.9*fps+.1/DeltaTime
    text(fps,WIDTH/2,HEIGHT-50)
end

@VictorFR Here's the above code, but instead of creating a mesh each draw cycle, this creates a mesh 1 time and updates only the screen positions each draw cycle. The result is almost a 2x increase in FPS. The below code runs at approx 37 FPS instead of the original 19 FPS. This just shows that there are different ways to do the same thing, some slow and some fast.

displayMode(FULLSCREEN)

function setup()
    fill(255)
    fps=60
    m=mesh()
    for z=1,20000 do
        m:addRect(math.random(WIDTH),math.random(HEIGHT),5,5)
        m:setRectColor(z,0,100,100,255)
    end
end

function draw()
    background(40, 40, 50)
    m:draw()
    fps=.9*fps+.1/DeltaTime
    text(fps,WIDTH/2,HEIGHT-50)
    for z=1,20000 do
        m:setRect(z,math.random(WIDTH),math.random(HEIGHT),5,5)
    end
end
