OnMouseDown()

[jakub_kriva]

I have a problem with the OnMouseDown() function
unfortunately it doesn’t work for me and I have no idea, could someone please send me the code to make it work for me instead of this one

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class Waypoint : MonoBehaviour

{

[SerializeField] GameObject towerPrefab;

[SerializeField] bool isPlaceable;

void OnMouseDown()

{

    if(isPlaceable)

    {

        Instantiate(towerPrefab,transform.position,Quaternion.identity);

    }

}

}

Hi,

In the Lecture Project Changes, which can be found in the Resources of most videos, you can find the instructor’s code.

And if OnMouseDown() still does not work, please check the description in the API.

Unity - Scripting API: MonoBehaviour.OnMouseDown()

I hope this helped.

    }

}

Good job!

Yes, the new input system might need a different solution. At least, people in this thread stated that OnMouseDown does not work with the new input system anymore.
