Get data from Multi Object/Value ArrayList [SOLVED]

by Aaron Scovel · in Torque X 2D · 09/13/2010 (10:26 am) · 5 replies

Hey everyone! I am stuck on a little problem with Arrays, I have added a debug screen shot so you guys can see what I'm talking about.

Now that I have setup the Array, I am trying to get the vector2 value from it.

Something like this? Vector2 _position = _options[0][1]; ? (1'st row, 2nd column).

Sorry for the noob question :-) Its a little over my 1st month in C#

    Retrieving an index from an array will return the object that you added to it. In your case:
    _options[0] // This would return an object of type 'OptionRow'
    From the looks of your screenshot, if you wanted the position that you added, you would do this:
    Vector2 _position = _options[0].newPosition;

    I get a build error if I try doing this.
    Quote:'object' does not contain a definition for 'newPosition' and no extension method 'newPosition' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)
    Obviously it looks like I need to define newPosition, but I don't know how to do this since its part of the array.

    I can do the following and it seems to define newPosition as a vector2
    Vector2 _position = ((OptionRow)_options[0]).newPosition;
    Now I get a new Build Error
    Quote:'StarterGame2D.OptionRow.newPosition' is inaccessible due to its protection level

    class OptionRow 
    { 
        int newOption; 
        Vector2 newPosition;

        public OptionRow(int o, Vector2 p) 
        { 
            newOption = o; 
            newPosition = p; 
        } 
    }
    Do I need to change something in the OptionRow class?

    yeah, make the value's in the class public. That should allow you to access things from outside the class. That would go for any class which you are using only as a "data structure", any variables you want to access need to be made public, and the default is that they are set to private.
