Attempting to implement a wait function in love.update

[icekiller8002]

Hi there, see title.

I want to make something that prints "asd" every second. I am using love.update to do this, below is my code.

Code: Select all

local dt = 0

function love.update(...)
  wait(1)
  print("asd")
end

function wait(i)
  dt = dt + 1
  
  if dt >= love.timer.getFPS() * i then
    -- what do i do from here?
  end
end

I feel like this is a good start; however, I don't know if it's possible to pause the code in order to wait on a function. How would I do this? Thanks in advance.

There are several ways of doing it. Here's a rudimentary one:

Code: Select all

function love.load()
  wait = 0
end

-- You update has a dt parameter
function love.update(dt)
  wait = wait + dt
  if wait >= 1 then
     wait = wait - 1
    print('asd')
  end
end

Like Sphyrth said that's the way to do it. Note that there is no guarantee that this will run EXACTLY every second because dt varies a little bit between frames. That's why I recommend using a "fixed" timestep.

Thank you sphyrth, I am aware of how that's one way to do it. I was wondering if there was a way to make a wait() function that pauses the update function. Is this even possible in Love2D?

"Pausing a function" is not a thing. You can either sleep, which will prevent execution of the rest of the game while sleeping.

Code: Select all

love.timer.sleep(1)

Or you can implement custom logic to make sure the parts you want to pause are not being updated while paused, as shown in the previous comments.

And chances are high that you do not want to sleep the main thread.
