Hi all,

I'm probably doing something very obviously wrong here but I'm not sure how to modify my code to correct it. Just wondering if anyone has any advice:

I create the variable:

C#

Array[,] myLevel = { { Green, Brown, positions1 }, { Green2, Brown2, positions2 } };

where each of the elements Green, Brown, positions1, etc. are of the type int[,].

I then want to create an instance of my method Game:

C#

public Game(int[,] Grass, int[,] Rocks, int[,] positions, int level)

I have used the following line to try to call the method:

C#

Game game1 = new Game(myLevel[thislevel, 0], myLevel[thislevel, 1], myLevel[thislevel, 2], thislevel);

I get the error message "Cannot convert from System.Array to int[*,*].

Thanks very much for any advice.

Stephen.

Solution 1

You need to declare myLevel as

C#

int[,][,] myLevel

That's what I would do.
If he can't change that type then cast the Array parameters;
<pre>
new Game((int[,])myLevel[thislevel, 0], (int[,])myLevel[thislevel, 1], (int[,])myLevel[thislevel, 2], thislevel); </pre>

Solution 2

myLevel is a multidimensional array of multidimensional int arrays, that is:

C#

int[,] [,] myLevel ={ { Green, Brown, positions1 }, { Green2, Brown2, positions2 } };
