added dung to project (133 grams)
added meat to project (150 grams)

meat (300 grams used of 150 grams needed)
dried dung (133 grams used of 133 grams needed)

ERROR: You need to use -150 grams of meat first.=

and I can't start to cook

Cancel the project and start it again?

Projects cannot be canceled when materials have been added.

Oh, yeah, sorry. Completely didn't even think of that.

LOL, you didn't work for your nick this time, did you...

Um... yeah... that is to... keep people from being... jealous of me...?





And actually, the story behind the nick...

I originally meant to be Solutious Maximus, which I wanted for hidden comical reasons. But, of course, when I mis-typed (don't understand how I mis-typed so horribly, the different keys are on completely different rows) I decided to keep the nick because my dad says I have the solution to everything.

of course, he was being a jerk.

When talking about your account details:

Location: 172.0.0.1

Didn't you mean 192.0.0.1?

no... actually I meant 127.0.0.1

But, this also has a comedic history.

Marol , any ideas?

I'm surprised that more meat can be added than the project calls for..... ....... would have thought there would be a restricting code or check for amount used not allowing more than the project requires to be added, something like:
(Pseudo Code)
If addedmeat > projectmeatgramsrequired then
"project only needs 150 grams"
else if addedmeat < projectmeatgramsrequired then
<add>
elseif addedmeat <1 then
"need to add minimum of 1 gram "
and so on.....

Perhaps there is a check like this and there is another reason for the glitch? First time I've seen more meat added than required.

Sky, it seems simple for single user system. But in paralel systems two players can simultaneously use meat on project. So imagine such situation:

1. Player A - script checks if there's room for meat in project - yes, there is - continue.
2. Player B - script checks if there's room for meat in project - yes, there is - continue.
3. Player A - script adds 150 meat to the project.
4. Player B - scrpit adds 150 meat to the project.

I realize it can be complex.... the 'connection' was slower too so this also may be a factor. I did message Chris the details, should I message you my account details and character?

You could have sent the details to me as well... Anyway - I fixed your project.

Thanks Marol

Something like this happened to me once. I was grilling meat with dung, and I added the dung fine, and then added the meat, but when I went to work on it, it said I still needed to add the meat. I checked the project and it said that no meat was used on the project yet, even though in the events page it logged that I had added the meat. There weren't even any other meat grilling projects at that time. I didn't really care, I just added the meat again, since I had a ton, but it was kind of wierd.

Can't you lock the project before step 1? so the flow would become something like

1. Player A script acquires lock on project
2. Player A script checks if there's room for 150 meat in the project
3. Player B script waits on lock
4. Player A script adds 150 meat
5. Player A script releases lock
6. Player B script acquires lock
7. Player B script checks to see whether there's room for 150 meat - there isn't.
8. Player B script releases lock.

Or does the database not support transactions?
