Priority Curing System - Trying to Match Values in a Table

[Jules]

Hey everyone, it's me again...

So, after scouring the Forums, I couldn't quite find what I'm looking for. Here's my problem. I'm building a Priority Curing System for Lusternia, and the way I'm going to go about it is simple. When the affliction line pops up on the MUD screen, I have triggers set up to capture the line, add the appropriate affliction to a Lua table, then running an alias that searches the table for the appropriate affliction, and cures it. Here's how it should look:

Code: Select all

Trigger
Name: Prone
Matches: You sit down. 
Script:

listAdd( affs, "prone" )
send(cureAffs)

Now, how would I set up the alias to search for the appropriate value (in this case, "prone"), and fire off the correct cure for there? I already have alias' set up that will cure every affliction in the game (in the case of "prone", all I'd have to do is "stand"), so that's not a problem.

Also, related, how would I search for the appropriate value to find within the Table if I had more than one affliction in the list ("prone", "asleep", "bleeding", etc...)?

So you basically want a key-value pair table, I'm guessing. Key would be the affliction name, value is if you have it or no. This page would be useful to you, in the "Tables as dictionaries" section. Along with this one: http://lua-users.org/wiki/TableLibraryTutorial

Though really, as someone who has built a successful system already, you'd get much more flexibility and simplicity if you use a series of if statements when doing the priority curing. You can still store the stuff in a table, but when curing, don't do a for loop on it.

Thank you for the links! I'll look over them and see how that helps!

And could you go into your last statement a bit more? What do you mean by using a series of statements?

[Vadi]

Code: Select all

if affs.paralys == 1 then
    eat ("bloodroot")
else if affs.stupidity == 1 and not eating == 1 then
    eat ("goldenseal")
....

Like that. So not a for loop, but a series of if statements.

The flexibility comes from being able to use multiple conditions on one if.

[Jules]

But will it still be fast?

[Vadi]

Yeah.

[Verthar]

if affs.paralys == 1 then
eat ("bloodroot")
else if affs.stupidity == 1 and not eating == 1 then
eat ("goldenseal")

Now with something like this, would it just be a further series of else if statements following, giving priority in that order? Or can they be bunched in some other way?

Sorry, I have a tough time understanding coding/scripting.

[naftali]

you could. There are more elegant ways to do it though. For instance, if you wanted to you could do something like this:

Code: [show] | [select all] lua

priorities = { "paralysis", "stupidity", "weakness" }
cures = {
	paralysis = "bloodroot",
	stupidity = "goldenseal",
	weakness = "kelp"
}

for _,thisaff in ipairs(priorities) do
	if affs[thisaff] == 1 then
		eat(cures[thisaff])
		break
	end
end

There are lots of ways to improve this, but this is already much easier to deal with than a list of 50 if/then statements.

I for one don't keep a list of variables, I keep a table that adds elements when I get them, and deletes them afterwards. This makes the parsing process faster, because it's easy to push through one or two elements, but much costlier to parse through... say.... 200 like in Lusternia.

[Vadi]

There are more than 200. More like 250+, and depends on how you set it up as well. I'm nearing 280ish and aren't done yet
