How do i wait until a certain condiction is given?

[arthurgps2]

I've tried

timer=require'hump.timer'

timer.script(function(wait)
repeat
wait(0)
until condiction
end)

but it didn't worked. Please help me!

You shouldn’t wait in a "while" loop, because it hangs the program until condition is met. Rather, you should check every update for your condition and if it's not there, don't take action (don't advance animation, don't move pieces, etc.)

A very stupid (and not-that-precise) but working example.

Code: Select all

__POSTPONED = {}

function update_timers(dt)
   for k,v in pairs(__POSTPONED) do
       v.ttl = v.ttl-dt
	   if v.ttl<0 then
	      v.func(v.args)
		  __POSTPONED[k] = nil
	   end
   end
end

function after(dt, func, ...)
   __POSTPONED[#__POSTPONED+1] = {ttl = dt, func = func, args = ...}
end

Easy way:

Code: Select all

timeWaited = 0
timeToWait = 10

function love.update(dt)
    timeWaited = timeWaited + 1
    if timeWaited >= timeToWait then
        --do something here
    end
end

love.update will loop endlessly,
that way you can get to know when a certain event happens.
In that case you wanna do something after 10 seconds

Easy way:

That will do something after 10 frames, and then once every frame.

To make it go after 10 seconds, add dt instead of 1. To stop it from activating every frame after that, have a boolean flag that stops that from happening:

Code: Select all

timeWaited = 0
timeToWait = 10
timerActive = true

function love.update(dt)
    timeWaited = timeWaited + dt
    if timerActive and timeWaited >= timeToWait then
        timerActive = false
        --do something here
    end
end
