Var value from var name

PHP Code:


		
			
//#CLIENTSIDE

public function getVarFromName(varname) {

  if (varname.pos(".") == -1) return -1;

  temp.tokens = varname.tokenize(".");

  temp.objvar = new TStaticVar();

  temp.objvar.copyfrom((@temp.tokens[0]));

  return getSubObj(temp.objvar, temp.tokens.subarray(1, temp.tokens.size() - 2)).(@temp.tokens[temp.tokens.size() - 1]);

}



public function getSubObj(obj,subobjstrarray) {

  if (subobjstrarray.size()) return getSubObj(obj.(@subobjstrarray[0]), subobjstrarray.subarray(1, subobjstrarray.size() - 1));

  else return obj;

}

In 'getVarFromName', the function returns -1 if the input string does not have an object prefix. I would like to return a variable that does not have an object prefix but I am having trouble figuring out how to do so.

this.(@"name"), since there is an object prefix, gives me the correct result. (The name of the weapon)

(@"mousescreenx") gives me 'mousescreenx' as a string.

Is there a solution this problem?

Try makevar:

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

  echo(makevar("mousescreenx")); // echos pixel position of mouse on screen

}

Other makevar example..

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

  temp.really.long.var.something = "HA";

  temp.start = "temp.really.long.";

  temp.value = makevar(temp.start @ "var.something");

  echo(temp.value); // echos "HA"

}

What are you doing that requires that functionality though?

Off the top of my head I can only see myself using it in dynamic commands (I.e: /echovar varname).

Nothing in particular. I see no documentation on makevar, and I did not know it existed. So I recreated it for scripting practice and any possible future use.

i've never used makevar myself, may i ask what's the difference?

PHP Code:


		
			
makevar("this.foo_bar") = "var";

PHP Code:


		
			
this.(@"foo_bar") = "var";

just for the sake of future reference'

There is essentially no difference except that sometimes you can't use the second example and have to use makevar (I think variables that don't have a prefix/object?). Avoid makevar if possible.
