Is it possible to parse the ifused field into a variable?

So basically if i have a variable let's just say "bob" and set it to bob = 0 in the init, then if i put a number in the ifused field of the entity, can i take that number from the ifused field and change the bob variable to that number?

no but you can use the strength or name field instead.

Ah great, i'm working on a set of scripts for basic quests and i want to make it as easy as possible for anyone to just use, so i thought to have it read the name field into a variable and have them number the entities to add them to the quest chains, but then i thought what if i wanted to prompt the name of the item, but if i can use the strength for the number variable, i can still use the name for the name prompt, that shouls work perfectly.

The only issue is obviously the strength part is how many hit points it has so if it's shot it will be destroyed, is it right you can make it unkillable by changing explodable to no? or is there another option needed to be set for that?

I can't check at the moment because i am not at a pc with gameguru on, but i think this is right, can you proof read for me?

Basically the actual quest script will have each quest associated to g_qid and with this script on an object i'm hoping when you are close to the object it will prompt "Press E to collect the itemname" IF the number in the strength field is the same g_qid on the quest script, and when you press E it will progress g_qid on the quest script by one triggering the next quest and destroy the item.

Does it look right to you?

Looks reasonable.

After the line g_qnum[e] = g_Entity[e].health put SetEntityHealth( e, 999999 ) or similar to make sure the entity can't be killed (or at least without an awful lot of hits ).

What I tend to do is use the name field and separate the values using '_' then split them out in the script, i.e. if you have a health collectable and you wanted it to give 20 health, have the name as 'health_20'.

The code to parse the string would look something like this:

Right been playing with it, had to make a few changes, nil fields and such, but i got it working, and also wrote a few more scripts.

So far there are two types of quest; a single item collection quest, and a multi item collection quest.

There is also a journal/tracker which is viewed and hidden by pressing the J key.

I'm trying to make the user setup of this system as easy as possible, all the user needs to do is:

1. Change the title and text info for each quest in "simplequest.lua" (5 quest slots by default, but more can be added by copy/pasting a slot and changing it's ID number).
2. Place a dynamic object in the map and in its properties panel change its strength field to the ID number of the quest it's to be associated with, and apply one of the two collect scripts to it.

For the collect script place only one item per number in the strength field.
For the multi collect script, place three objects with the same number in their strength field.

That's as easy as i can get it.

I'm also working on a quest trigger zone, and a use animated object (lever, button etc.) script.

Here's how it looks in game at the moment:



Once i have them sorted i will submit it to Lee and see if he will add it to GameGuru so we have at least a basic easy to use quest system by default. I've actually been meaning to do this for ages, but i couldn't work out how to avoid massive editing of scripts by users, then it hit me that i could use the name field to control the variables, and again it hit me after you guys helped me that i could use the strength field, thus cutting down the user edits drastically and making it more feasible as an easy quest system.

Just had a thought, apparently you can write scripts so that you can have more than one piece of information in the name field, for example you could have the name as "a box,1" and read the part before the comma as the name and the part after the comma parsed as a variable, the code below works for converting a number in the name field as a variable, but how would i change it if i wanted to call it "box,1" and have the "box" part show as the name on the prompt, and the "1" part put into the g_qnum variable? I'd rather do it that way so as not to use up the strength field, or if i wanted to use it in a zone which doesn't have a strength field.

Yeah i saw that, i have no idea how that would fit in my script though.

Replace lines 7 an 8 with your 3 lines?

yes basically, just change the _ to , in what you're looking for.
string.sub basically has 3 inputs;
1. the text to edit
2. the starting point
3. the end point
we're using string.find to find the start points and end points (i.e. the comma's), & +/- 1 because we don't want to display the comma

Great, thanks guys ive learned a lot, i always apreciate your input.

I'll stick both your names in the credits when it's done

I'm not actually doing this for myself, theres a chap on the steam discussions complaining that fundamental basics like quest systems are missing from gsmeguru that should be default systems, and to be honest to a point i understand his view (i don't entirely agree but i understand) so im trying to write a series of scripts for a quest system that are as easy as possible for the user to set up, so i can send it to Lee for possible inclusion to gameguru so we at least have something basic by default for people who expect that sort of thing. Its about time i contributed something worthwhile.

Now that i know how to parse the name field with multiple info I will be able to actually give it a lot more options than originally planned.

If this sort of feature is something you think you can make use of I can add a function to utillib to parse a string and return a list of the sub strings based on separator, sort of like how args are handled in C programs.

Here is the generic function


Simply call it like this:


Then you can access the values directly:


To make it even simpler I've defaulted the separator to a comma so if your string uses a comma separator simply call the function like so:
args[ e ] = GetArgs( name )

I have been away from the PC for a while so haven't had a chance to do anything with it, but I've been reading through it, i'm not entirely certain how to add it to my script though, would the below work?



So if i for example called the objects barrel,1 this would set then g-name[e] to barrel, and g_num[e] to 1 right?

Looking at this, with this function i could have as many args as i like, so i could effectively add a third arg to the chain and have that define a variable that controls how many steps the quest has, so i wouldn't need a separate single or multi quest script?

Yes but put the GetArgs function at the top before the _init function.

Yes you can have as many arguments as you like as long as they are all separated by the same separator character.

If they are numeric remember to use tonumber() to convert them:

g_qnum[e] = tonumber( myArgs[ 2 ] )


for example.

OK, managed to work out what was wrong with smallg's one, it was just a couple of the variables named wrong, checked Amen one but still can't get it working.

If i was to add a third variable (g_steps[E]) to smallg's method, what would i need to add/change?

You are specifying the separator as "_" when you are using ","!

Take out the separator part (as it defaults to "," in the function), i.e. just have:

args[ e ] = GetArgs( name )

Been trying to get this to work all day, no joy. It just doesn't seem to parse the names into the tables, i place a barrel, i change it's name to Barrel,1,1 and add the attached script, and nothing happens, it doesn't even prompt.



Just a thought, my scripting laptop i use when at work (which i've been texting this on) only uses 1.14 because it's only a DX9 laptop, is this too early a version for the function you created?

If that is so, i would really like it to remain compatible with as many versions of GG as possible, so what and how would i change the method in the script smallg posted to include three parameters in the name?

Part of the problem is that if an error occurs in the _init function it doesn't get reported on screen.

What I do nowadays is do my initialisation in the _main function the first time it runs. Only when it is all debugged and working fine do I move initialisation code into the _init function.
