How do I use a text string for locate()?

Ok, I have a var, called Locations="100,200,3", now, I have an obj, called A, and I need to somehow place A at 100,200,3 using only the info in the Locations var, something like A.loc=locate(Locations), although that example doesnt work for some reason, is there any way you know of to do this? And yes it -has- to be done with a text string.

Why does it have to be done with a text string? :/

You could either make three seperate vars, or use a locate() in the var.

The locate() procedure can only get x,y,z values as numerical arguments. What this means is you need to find a way to convert your string of coordinates into numerical values. But before you do that you need to separate the values in the string.

http://developer.byond.com/hub/Deadron/TextHandling is a good resource for this job. Right after you include the lib into your project, you use the dd_text2list(text, separator) function in the lib.

var/Coord = "100,200,3"
var/L[] = dd_text2list(Coord, ",")
// Now L contains 3 text strings each containing are x,y, and z values.
var/numlist[] = stringList2numList(L)
// Converts string list into a number list.
A.loc = locate(numlist[1],numlist[2],numlist[3])

proc/stringList2numList(list/stringlist)
    var/numlist[stringlist.len]
    // Creates a numlist same size as string list
    var/i
    for(i=1;i<=numlist.len;i++)
        numlist[i] = text2num(stringlist[i])
    return numlist

I'm pretty sure this is not the best code to use in your own code. It's just an example of how it could be done. I hope it provides some insight.

Actually no I cant, because the reason I need it is so I can save every thing on the map as text then restore it later from the text. But that other guys response probably solved it.

The map IS text.
