Convert C# to JS

Questions & Answers

Hi good night

I was looking for an algorithm to make a grid on the ground, found in C # but I need to be in JS. I started the conversion but did not get a part, I would like somebody’s help.
Original algorithm:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Grid : MonoBehaviour {
	
	public Terrain terrain; //terrain grid is attached to
	public bool ShowGrid = false;
	public int CellSize = 10;
	
	private Vector3 terrainSize;
	private Vector3 origin;
	
	private int width;
	private int height;
	
	private List<GameObject> objects;
	
	void Start ()
	{
		terrainSize = terrain.terrainData.size;
		origin = terrain.transform.position;
		
		width = (int)terrainSize.z / CellSize;
		height = (int)terrainSize.x / CellSize;
		
		objects = new List<GameObject>();
		
		BuildGrid();  
	}
	
	void Update ()
	{
		foreach(GameObject obj in objects)
			obj.SetActive(ShowGrid);
	}
	
	void BuildGrid()
	{  
		for(int x = 0; x < width; x++)
		{
			for(int y = 0; y < height; y++)
			{
				GameObject go = GameObject.CreatePrimitive(PrimitiveType.Cube);
				Vector3 pos = GetWorldPosition(new Vector2(x,y));
				pos += new Vector3(CellSize / 2, terrain.SampleHeight(GetWorldPosition(new Vector2(x,y))), CellSize /2);
				go.transform.position = pos;
				if(x==0)
				{
					go.renderer.material.color = Color.red;
				}
				if(y==0)
					go.renderer.material.color = Color.green;
				
				go.transform.localScale = new Vector3(CellSize /2, CellSize /2, CellSize/2);
				go.transform.parent = transform;
				go.SetActive(false);
				
				objects.Add(go);
			}
		} 
	}
	
	public Vector3 GetWorldPosition(Vector2 gridPosition)
	{
		return new Vector3(origin.z + (gridPosition.x * CellSize), origin.y, origin.x + (gridPosition.y * CellSize));
	}
	
	public Vector2 GetGridPosition(Vector3 worldPosition)
	{
		return new Vector2(worldPosition.z / CellSize, worldPosition.x / CellSize);
	}
}

Part I was unable to convert:

            public Vector3 GetWorldPosition(Vector2 gridPosition)
    	{
    		return new Vector3(origin.z + (gridPosition.x * CellSize), origin.y, origin.x + (gridPosition.y * CellSize));
    	}
    	
    	public Vector2 GetGridPosition(Vector3 worldPosition)
    	{
    		return new Vector2(worldPosition.z / CellSize, worldPosition.x / CellSize);
    	}

Thanks for the help already.

Looking just at the lines you had trouble with:

   function GetWorldPosition(gridPosition : Vector2 ) : Vector3 
    {
       return Vector3(origin.z + (gridPosition.x * CellSize), origin.y, origin.x + (gridPosition.y * CellSize));
    }

    function GetGridPosition(worldPosition : Vector3) : Vector2 
    {
       return Vector2(worldPosition.z / CellSize, worldPosition.x / CellSize);
    }
