Scripting a time-difference event?

I've made a script for a fireplace where the fire grows when firewood is added, but gets smaller as time passes, eventually becoming just a pile of ashes:

but there's a problem:

As you can see in the code, the fire goes from stage 5 to stage 0 incrementally every hour. So if you press the wait button and wait one hour a few times, or just don't do anything and literally wait, you'll see it happen.

However, if I wait and select a chunk of time, e.g. 8 hours when I go to bed, when I get up, the fire will only have gone down 1 stage, presumably because the script only works once per wait.

How can I get round this?

 

I was thinking I'd need to create a timer where the "Current Time" is compared to a "Start Time" value which was set upon adding the firewood.

So because 5 is the maximum and I can't add more wood at that level,  sleeping for 6 hours would mean the hour different between the StartTime and CurrentTime is greater than 5 so the fire will be at Stage 0 upon waking up.

Is that possible? If so how would I go about writing the code?

 

EDIT: Just realized the Survival Mode has similar time-based stuff (I think), I'll check it out

When you register for the update, store the current time in a script wide local variable. Say ST for start time.

Then in the update event after assigning the pGlobal variable insert the following (needs tested). 

Float StagesPassed = Math.Floor(((Utility.GetCurrentGameTime() - ST) * 24) / pHourstoWait)
If (pGlobal - StagesPassed) > 0
  pGlobal = CurrentStage - StagesPassed
Else
  pGlobal = 0
EndIf

The above should take the difference between the current time and the start, break it down to hours, and divide it by the number of hours to wait.  Then round that down to the nearest whole number (this should be the number of stages that should have passed).  If the current stage value less the result, is greater than zero assign the new value otherwise assign zero and proceed with the rest of the update event.

I guess I've stored the CurrentTime as a local variable with this:

float GetCurrentTime = ST

 

However, the next part is giving me some error messages:

variable CurrentStage is undefined
cannot subtract a none from a float (cast missing or types unrelated)
type mismatch while assigning to a int (cast missing or types unrelated)

float ST ; somewhere in the preamble of your script

ST = Game.getCurrentGameTime() ; when you start your timed delay

The trick is to do it at the point where you start your timed delay... "when you register for update" in Ishara's reply.

Yeah that's what I've done, at least I think I have.

Is this corrrect?

A local script variable is one that is defined in the empty state but whose value can be changed as needed throughout the script.

A local event / function variable is one that is defined inside of an event or function and used exclusively within that event or function.

Your empty state should have:  Float ST

And at each update registration you should have:  ST = Utility.GetCurrentGameTime()

As far as the CurrentStage thing, that was a mistake.  I had tried a couple different approaches before realizing I was making things too complicated.  It was a forgotten leftover.  Replace it with pGlobal and it should work as intended.

Oh I see. Thanks very much for taking the time to help out with this.

You mentioned "empty state" but my script doesn't have any states set. I figured I didn't need them.

 

If you wouldn't mind, could you take a look at how I have the current script and tell me what needs to be changed?

I'm having the following error: "type mismatch while assigning to a int (cast missing or types unrelated)", perhaps because I don't have any states set up?

Here's the script:

Change 

pGlobal = pGlobal - StagesPassed

to 

pGlobal = (pGlobal - StagesPassed) as Int

The reason for this is that pGlobal is defined as an integer.  But up until this point we have been working with floats.  The end result being assigned to the pGlobal variable needs to be cast into an integer.  A simple oversight.

As far as the empty state, that is what any area outside of defined states would be called.  So if a script does not have any defined states, that script is completely in the empty state.  Should someone state that a variable declaration needs to be in the empty state, it means that it belongs outside of any state definitions, events or functions. Typically where properties reside.

You can also change  

float property ST Auto

into 

Float ST

Only two reasons to make a variable a property:

  1. The variable cannot be defined within the script itself and instead must be assigned something with the Creation Kit.
  2. The variable needs to be accessed by another script.
