How to access elements in a vector? How to return a variable? [SOLVED]
by RJAG Entertainment · in Torque 2D Beginner · 03/17/2013 (7:09 pm) · 4 replies
I browsed through the entire syntax and wiki, but was unable to find this information.
Under the section "VECTORS", it says it automatically creates a Vector2D if given two numbers, like so:
%position = "25 32";
^becomes a 2 element vector when created.
How do you access the different elements though?
Something like,
%ptX = %position.1stElement;
%ptY = %position.2ndElement;
In C++ it would look something like:
Point ptPOS;
int iX = ptPOS.X;
int iY = ptPOS.Y;
Also, how do you return a variable?

Searching through the syntax wiki it says
[return var;]but this crashes T2D for me. However, a normal
return var;doesn't crash.

(%ptMap is a Vector2 already, like "5 5" or "10 10")
I guess I had an older version that didn't allow you to do .x, .y.
I found out the problem accidentally, when I went to the most recent news on T2D.

Nevermind, I wasn't running the updated version of T2D MIT and also forgot to create the variable as a Vector2D as well.(%ptMap is a Vector2 already, like "5 5" or "10 10")
%ptPlot = "0 0"; //this is important, as it wouldn't work without first making %ptPlot a Vector2D. %ptPlot.x = %ptMap.x + %FancyEquation; %ptPlot.y = %ptMap.y + %FancyEquation;

String Accessors
You can now access a string using:
.x .y .z .w (index 0 to 3)
.r .g .b .a (index 0 to 3)
.width .height (index 0 and 1)
._n (index n)
.count (get a count of words equivalent to "getWordCount(...)")

Oh, thank you Doc308. Didn't know that would work as well. That is extremely useful to know getWord.

Ex:
returns of variables are the same as C++, not sure what the brackets would be in the wiki syntax, as it isn't the way it works.
So your second example is correct. Though usually it would have a % or $ in front of the variable for the type (local vs global)
