Clock( ) in a loop

LinkCraft

For some reason having Clock( ) in a loop will crash fuze after like a min.

Please can you provide example code? I've just tried this and it works fine for me;

elapsed = time()

loop
  clear()

  printAt( 0, 0, clock() )
  printAt( 0, 2, "Elapsed = ", int( time() - elapsed), " seconds" )

  update()
repeat

5 minutes and counting! It may be unrelated to clock() more likely from not having a clear() or update() in your loop?

This code crashes Fuze after 2 minutes.
Maybe Clock() and Controls() are not compatible.
It's OK if you comment one of these functions (inside the loop).

cl = Clock()
ctrl = Controls(0)
Loop
    Clear()
    cl = Clock()
    ctrl = Controls(0)
    PrintAt( 10, 10, "wait 2 minutes" )
    Update()
Repeat

@doumdoum I have confirmed this one and raised an issue. Interestingly if you remove the first two lines (which will make the variables local to the loop and not global) the problem does not occur.

@pianofire said in Clock( ) in a loop:

That info's pure gold. I would have instantly assumed this of a function but not necessarily considered the scope inside of a loop. That might help elsewhere too.

If your are using this sort of code to debounce your button presses:

oldc = controls(0)
loop
  clear()
  c = controls(0)
  if c.a and !oldc.a then
    print("hello")
  endif
  update()
  oldc = c
repeat

You will have this problem. here is a work around until it is patched:

oldc = [ .a = 0, .b = 0 ]
loop
  clear()
  c = controls(0)
  if c.a and !oldc.a then
    print("hello")
  endif
  update()
  oldc = [ .a = c.a, .b = c.b ]
repeat

Thank you so much, this has caused me to rip my hair out today, I never would have guessed the solution at all.

So my latest finding on this problem is that this seems to work fine:

oldc = controls(0)
loop
  play()
repeat

function play()
  clear()
  c = controls(0)
  if c.a and !oldc.a then
    print("hello")
  endif
  update()
  oldc = c
return void
