Grid System – Unity3D (C#)

Grid system is used mostly in RTS games. Your characters or buildings move on grids. You need a matrix to create a grid system.

public float cell_size = 2.0f;
	
	private float x, y, z;

	void Start() {
		x = 0f;
		y = 0f;
		z = 0f;
		
	}
	
	void Update () {
		x = Mathf.Round(transform.position.x / cell_size) * cell_size;
		y = Mathf.Round(transform.position.y / cell_size) * cell_size;
		z = transform.position.z;
		transform.position = new Vector3(x, y, z);
	}
