IndexOutOfRangeException Obstruction Cells

Jan 30, 2013 at 2:56 AM

I am attempting to create a path for the creeps to travel by using Obstruction cells 

When I do this I run into the below error

At the time of this error the following values were
IndexY = 11
Columns = 19
indexX = 4


namespace Coding4Fun.ScriptTD.Engine.Logic
    public class Grid
        public Cell this[int indexX, int indexY]
            get { return CellArray[(indexY * Columns) + indexX]; }

Currently, It is a fixed 11x19 grid.  Since we're zero-based indexed, that means valid values are 0-10 for Y, by 0-18 for x.

Oh man I feel like a moron I can't believe I missed that.
I figure I will share with everyone an easy Obstruction Cell Builder When you go to that link click on the cells you want to be blocked by an obstruction and it will generate the XML code for you.
Work smarter not harder.

Thank you again
