Limit where I can Instantiate on mousedown?

Questions & Answers
1

My script puts an object at the position of the mouse, regardless of the position.

I’d like to limit where I can place the object to a small area around the player sprite.

Say if mouse X if greater than (X position + a little) of the players X than the object wont Instantiate. I’ve tried if statements along these lines but haven’t been able to get it to work.

Here is the placement script.

public GameObject seedlings;
public GameObject player;
Vector3 mousePOS = Input.mousePosition;


// Use this for initialization
void Start(){}

// Update is called once per frame
void Update()
{
    PlantInGround();
}

void PlantInGround()
{
    Vector3 mousePOS = Input.mousePosition;
  

        if (Input.GetMouseButtonDown(0))
        {
            mousePOS.z = +12;
            mousePOS = Camera.main.ScreenToWorldPoint(mousePOS);
            Instantiate(seedlings, (mousePOS), Quaternion.identity);
            Debug.Log(mousePOS);
        }
}

}

This should do the job. Limit if X and Z distances between player and mousePOS are smaller than 2.

I moved your input check to Update, so you don’t call “PlantInGround” at all if you did not click.

I also commented a line in your code that I don’t understand, where you “mousePOS .z += 12”. Why is this before the following line? Your setting mousePOS.z then change completely mousePOS on the next line…

public GameObject seedlings;
public GameObject player;
Vector3 mousePOS = Input.mousePosition;

void Update()
{
	if (Input.GetMouseButtonDown(0))
	{
		PlantInGround();
	}
}

void PlantInGround()
{
	Vector3 mousePOS = Input.mousePosition;
	
	//mousePOS.z = +12;
	mousePOS = Camera.main.ScreenToWorldPoint(mousePOS);
	if ((Mathf.Abs(player.transform.position.x - mousePOS.x) < 2f) && (Mathf.Abs(player.transform.position.z - mousePOS.z) < 2f))
	{
		Instantiate(seedlings, mousePOS, Quaternion.identity);
	}
	Debug.Log(mousePOS);
}

Okay so for whatever reason GrKls code did not work for me. So I took it and changed the if statement and it worked exactly how I wanted it to. Thanks for the help man. Leaving this hear for others.

public class PlantItem : MonoBehaviour
{

public GameObject seedlings;
public GameObject player;
Vector3 mousePOS = Input.mousePosition;

void Update()
{
    if (!Input.GetMouseButtonDown(0))
    {
        PlantInGround();
    }
}

void PlantInGround()
{
    Vector3 mousePOS = Input.mousePosition;

    mousePOS.z = +12;
    mousePOS = Camera.main.ScreenToWorldPoint(mousePOS);
    if (((player.transform.position.y < mousePOS.y + 0.5) && (player.transform.position.y > mousePOS.y - 1.5)) && ((player.transform.position.x < mousePOS.x + 1) && (player.transform.position.x > mousePOS.x - 1)))
    {
        Instantiate(seedlings, mousePOS, Quaternion.identity);
     
    }
}

}
