How To Get A String In A Concentated Argument

11-01-2006, 01:01 AM

I am trying to make a system for Wc3 and so far I have only one problem, ill give a quick example of what my problem is

lets say there is a function that when you call you have a string as an argument that has multiple options, something like this

JASS:

call RandomFunction("Group A = Jack+Jill, Group B = Susan + Sally")

When the actual function is being called how would you detect the seperate string. Lets suppose we have 2 string arrays, one that will hold all the values in Group A and one that will hold all the values in Group B

i.e.

JASS:

function RandomFunction takes string s returns nothing
local array string GroupA
local array string GroupB

What would you do after this so in the array Group A you would get in index 1, Jack and Index 2 Jill and in Group B in index 1 you would get Susan and Index 2 you would get Sally. The order isn't important but there isnt going to be a set number of options you can enter. I want the system so you can enter as many options as you want and the function will detect when to reach the end

Anopob	Sorry if I don't understand what you're talking about. So what you want is that say you have Group A containing Jack + Jill, and Group A has 2 indexes; Index 1 shows Jack + Jill and Index 2 shows Jack/Jill? Then why not just create another variable to show Jack/Jill?

No No No
When you called the function with a string, i want to be able to detect all the options that was entered into the string in the argument for the function that was called

So basically I want to be able to get:
GroupA[1] = Jack
GroupA[2] = Jill
GroupB[1] = Susan
GroupB[2] = Sally

in the RandomFunction. Obviously you would use a loop for the indexes and to be able to detect when you reach the last option

call RandomFunction("Group A = Jack+Jill, Group B = Susan + Sally")
And why wouldn't you simply use multiple arguments?

Also, if you really need to, you can regulate the length of each individual series of characters.
So if you knew you'd have 8 characters for each 'series' in the concatenated string --

JASS:

function RandomFunction takes string s returns nothing
    local string array series
    local integer index = 0
    local integer ends = StringLength(s)
    
    loop
        exitwhen index >= ends
        set series[(index/8)] = SubString(s, index, index+8)
        set index = index + 8
    endloop
    
    //Do stuff to your string array.
endfunction

You could also expand it so you can add an argument for size of string series if you want.
So yeah.

PandaMine	Well i dont want to use multiple arguments because I want no limit to the number of values that the function can take, which is why it is in the form of the string. i.e. I want a person to be able to enter lets say 2 options, or maybe 7 options in the same function, i need the amount of arguments to be varied

Vexorian	If you set a limit like 21 strings you could use things like dynamic arrays. Else just use tokenizing, I don't really get the sense of the Group A and Group B thing you need to parse it, so just do it.

PipeDream	Is the data part of the script or is it input ingame? If it's in game, use a single character token to delimit values, like "a,b,c". If it's part of the script and you really need a function to take multiple arguments, use a stack or array NOT STRINGS!
