Performance questions

Here´s my project. The .love file didn´t run so i simply zip the project folder. Please draw the project folde on your love.exe

You really need to add some formatting to that.

You´re right. My code is just uncleaned^^.

You probably zipped the project folder, am I right?

The way to make a .love file is not creating a .zip file from the project folder, but the from the contents of the project folder (main.lua and the gfx directory in this case).

[Wombat]

Yes, i already know.

But it didn´t worked when i do the main.lua in the top-level.

I think its because you have some case inconsistencies. If a folder has a capital letter in it, the code has to also have a capital letter (myBlaster vs myblaster)

I have another question: How can i generate a constant framerate in my programs?

Somenone said it´s good to use love.timer.step() others say that it´s better multiplie all counters with dt.
And i think there are a lot of other possibilities...

Do you know a good and testet way to make a constante framrate in .love programs?

Simply put, you can't.

There are certain tricks you can use, but they are all imperfect. Instead it is a good idea to anticipate the variability of the world. This means using dt, among other things.

The easiest way is like :

Code: Select all

local Timer0 = 0
local SOMENUMBER = 1

function love.update(dt)
Timer0 = Timer0+dt
if Timer0 > SOMENUMBER then
--do things here
Timer0 = 0
end
end

this way you have a somewhat constant update every 1(SOMENUMBER) second

The easiest way is like :

Code: Select all

    local Timer0 = 0
    local SOMENUMBER = 1

    function love.load(dt)
    Timer0 = Timer0+dt
    if Timer0 > SOMENUMBER then
    --do things here
    Timer0 = 0
    end
    end

this way you have a somewhat constant update every 1(SOMENUMBER) second

Unfortunately this doesn´t work for me. But thanks for your help

I found a solution that works for me:

Code: Select all

function load()
fps_buffer = 0
factor = 0.01
max_frame = 60
end


function update(dt)

fps = love.timer.getFPS( )
love.timer.sleep(fps_buffer)
if fps < max_frame then
fps_buffer = fps_buffer - factor
elseif fps > max_frame then
fps_buffer = fps_buffer + factor
end

end

At first you have to wait some seconds until the framerate has the value you want. I think i have to optimize it, so you don´t have to wait until the value max_frame is like you wish.

He should have said love.update(dt) when he said love.load(dt).

I found a solution that works for me:

Are you using LÖVE 0.5.0?

thanks for clearing out my horrible mistake
