Obtain the grid's coordinates

I am seeking assistance with creating a javascript function that can retrieve coordinates within the specified range of a start and endpoint on a grid. Below is a representation of the grid structure:

 _______________________
|       |       |       |
| -1,-1 |  0,-1 |  1,-1 |
|_______|_______|_______|
|       |       |       |
| -1,0  |  0,0  |  1,0  |
|_______|_______|_______|
|       |       |       |
| -1,1  |  0,1  |  1,1  |
|_______|_______|_______|

For example, if I specify the range from coordinates (-1,-1) to (0,0), I would expect to receive the following values: (-1,-1), (0,-1), (-1,0), (0,0).

Although these are basic mathematics principles, I am struggling to find an optimal solution for this problem.

Answer №1

If you need to generate a list of coordinates within a specified range, you can use the following function:

function GenerateCoordinatesInRange(xStart, xEnd, yStart, yEnd) {
    var currentX = xStart;
    var currentY = yStart;
    var result = []; // Placeholder for storing coordinates    

    while (currentX <= xEnd) {
        while (currentY <= yEnd) {
            result.push({ x: currentX, y: currentY });
            currentY++;
        }
        currentX++;
        currentY = yStart;
    }

    return result;
}

This function will provide you with an array of coordinates in the format shown below:

[
    0: { x: -1, y: -1},
    1: { x: -1, y: 0},
    ...
]
