[Solved] Set custom variable

[Datnes]

Hi, please help, I am new in W3 Scripting.

I wanna: set (variable of name(Content of Variable1)) = Variable2

 

[KILLCIDE]

Use the GUI "Set Variable" function?

Hi, please help, I am new in W3 Scripting...

A long journey awaits you...

For example if I write "Goldperscale 4" in chat, then Variable1 = "Goldperscale" and Variable2 = 4

Then: set Goldperscale = 4

 

[KILLCIDE]

Oh you need to make use of the Substring function then.

• Set EnteredChatString = (Entered chat string)
• Set GoldPerScale = (Substring(EnteredChatString, 14, (Length of EnteredChatString)))

I chose 14 because there are 13 characters in "Goldperscale "

How to explain this...

If I write in chat: "lumber 10" then it sets variable with name lumber to 10
If I write in chat: "gold 200" then it sets variable with name gold to 200
If there is no variable with name gold or lumber and still I write gold 200 or lumber 10, the variable cant be set.

^ exactly what KILLCIDE wrote,

You need a player chat event ( entered as substring ) for lumber and for gold.

I'm not sure converting a string to a variable reference is possible. A general purpose trigger than converts any "string number" chat message to "variable with name of string = number" probably isn't possible; this isn't python, unfortunately.

You'll have to write up a case for each variable you're using.

It is not possible to set a dynamic variable. All variable names, except some trigger events, require being declared at compile time.

One can simulate the mechanic using a switch of sorts. For example say you want to set the integer variables GoldIncome, WaveNumber or LivesLeft. The following function could be used to set the integer variable specified by a string to a specified value.

function SetIntegerVariable takes string varname, integer value returns nothing
    if varname = "GoldIncome" then
        set GoldIncome = value
    elseif varname = "WaveNumber"
        set WaveNumber = value
    elseif varname = "LivesLeft"
        set LivesLeft = value
    else
        // Cannot resolve variable.
        call BJDebugMsg("Invalid variable name!")
    endif
endfunction

Since this is a linear search, the more variables added to it the longer it will take to run. It could easily support hundreds of variables as long as it is called very infrequently. Different such functions would be needed for each type of variable, such as one for strings, one for reals etc. Through use of StringHash it should be possible to use a binary search instead of a linear search for better scaling, however for productive use some form of third party script would need to be created which generates the necessary code.
