problem with creating a lua timer and with playing a sound

[hummie]

I have 2 problem as the topic title suggests.

One of them being the problem that I dont know how to create a timer in lua.

On a other project I was used to a sleep(float) function.

The other thing that I tried was with os.time but that didn't work out as well.(crashed upon using it)

 

The second problem is that I can't find a method to let me play a sound and set the radius for it.(like a weapon that was fired)

I have found the playsound() method but I dont think it will be the same as a used gun, but more as a sound effect.

 

local function soundtest()local player = getSpecificPlayer(0)local weapon = player:getPrimaryHandItem():getName()print(weapon)if weapon == "Axe" thenprint(" :D") -- testingposworld = player:getCurrentSquare()print(posworld) --again testing--timer--end--play a soundendendEvents.OnWeaponSwing.Add(soundtest)

 

sorry for the code in the spoilers it doesnt seem to like me  .

Fixed your formatting.

IIRC I used the GameTime class to produce a counter some time ago. Not sure though.

 

For playing a sound check out my lockpicking mod. It creates a sound + a sound world object to attract zombies.

Ok thanks for the help with the formatting RoboMat.

I will check your suggestions tomorrow(or later today) since it is half past 12 here(AM).

But thanks for the help so far.

So I am back with the results from testing:

Got the sound working, the only thing that I need to do is tweak some values.

The bad news is, is that I dindn't got my timer/delay to work.

I tried to used getMinutes() to make a delay but got a error that reads out:"Object tried to call nil in soundtest"(on line 29)

 

Here is the code on pastebin.(since it looks a little bit cleaner there)

Object tried to call nil is referring to the method getMinutes() which is doesn't exist in your code. The way you are calling it, you would need your own lua function called getMinutes(), wheras what I think you want to do is call:

 

GameTime:getMinutes()

 

or

 

GameTime.getMinutes()

 

I'm not sure which off the top of my head. Essentially you need to specify that you want to call the getMinutes() function on the GameTime object.

 

In short replace line 29 with 

 

mins = GameTime:getMinutes()

 

You may need to change the colon to a period... I've not used lua in ages.

[hummie]

I tried wat you suggested but the error doesnt change at all.

The line is still line 29 with the same error.

 

Edit:

After giving the error some more thought and what you said.

Is it a possibillity that I need to do something with require'something'.

I looked at a example in this tutorial: http://theindiestone.com/forums/index.php/topic/61-robomats-modding-tutorials-updated-12112013/

But when searched for such a name in the javadocs I couldn't find any classes that matched.

[Stormy]

Try:

 

GameTime:getInstance():getMinutes()

[hummie]

ok thanks for the getInstance() part that made it work.

The only problem is that it crashes ones it excutes the script.

I think it spams to much since it crashes at the "print("not equal")" part.

When I remove that it still doesnt work.

 

Edit:
At this point I think it is more of a problem that I have not a work-around for wait/delay function.

On a other project I would use sleep() function inside a for or while loop, to prevent spamming the client/server.

Or to prevent some tasks from being executed to quikly in a row.

[Stormy]

Sorry. I guess I should have read the problem properly....

 

When writing lua scripts loops can not be used to wait for something to happen. Nor can you tell the thread to sleep for a little bit. Essentially doing so will cause the entire game to wait for the loop to finish and since the game never changes state, the game time is never increased and your while loop will always return false, waiting for eternity.

 

What I think people tend to do is add functions into the onTick event of the game. Something like, 

local startTime = GameTime:getInstance():GetMinutes()local myFunction = function()   local currentTime = GameTime:getInstance():GetMinutes()     if(currentTime == startTime+5)     print('5 minutes has passed')   endendEvents.OnTick.Add(myFunction)

Essentially you should think of tha game as being one massive loop. Everything in the Events.OnTick collection is executed once every cycle of that loop.

 

There is a more complex solution in this thread:

Thanks for the reply stormy it works.

Going to recap the solutions in a new reply to make it easier for the people with the same problems.

[hummie]

First of all thanks to RoboMat and Stormy for helping me out.

 

On the second post RoboMat solved my problems on how to play a sound.

On ninth post Stormy posted a solution to my timer problem.
