matrix pattern

hi,

i’ve got a matrix grid that changes size, currently its 10 x 10 but it can be 20 x20, or 5 x 5 so changable

i was wondering how to get a pattern like this. Using some sort of a formula

lets say that we have an

int gridColour =0;

if it’s purple gridColour = 1; and if its cyan/blue gridColour = 0;

int pattern1 = new int
{
0,0,0,0,0,0,0,0,0,0,
0,1,1,1,1,1,1,1,1,0,
0,1,0,0,0,0,0,0,1,0,
0,1,0,1,1,1,1,0,1,0,
0,1,0,1,0,0,1,0,1,0,
0,1,0,1,0,0,1,0,1,0,
0,1,0,1,1,1,1,0,1,0,
0,1,0,0,0,0,0,0,1,0,
0,1,1,1,1,1,1,1,1,0,
0,0,0,0,0,0,0,0,0,0,
};

matrixArr[ix,iy] = pattern1[iy*rand + ix];

This should work, but it’s untested.
Basically if you wanna pass a stored pattern you have to be able to parse it somehow, this is only one of many examples.

right so i have found a solution (this works in my script, may have been some errors as i had to change some variable names)

private int[,] matrixArr;
	int rand =0;
	string displayResult="";
	void Start ()
	{
 
		rand = (int)(Random.Range (5, 20));
		matrixArr = new int[rand, rand ];
 
 
		for (int ix = 0; ix < rand; ix++) {
			for (int iy = 0; iy < rand; iy++) {
				setColour (ix, iy);
 				displayResult+=matrixArr [ix, iy];
			}
			displayResult+="

";
}

		Debug.Log(displayResult);
	}
 
	void setColour (int ix, int iy)
	{
		for (int i=0; i < rand; i++) {
			if (ix == i && iy >= i && iy < rand - 1 - i || iy == i && ix >= i && ix < rand - 1 - i
                    || ix == rand - 1 - i && iy >= i && iy <= rand - 1 - i || iy == rand - 1 - i && ix >= i && ix <= rand - 1 - i) {
				matrixArr [ix, iy] = i % 2;
				
				break;
			}   
		}
	}
