Unable to spawn and drag via button click
I want to make a system where on the button click i am able to spawn the prefab and drag it to the place i want without taking my finger off the screen. For that i have made a drag script which is attached to my prefab :-
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Script_PC_drag : MonoBehaviour {
Vector3 dist;
float posX;
float posY;
void OnMouseDown()
{
dist = Camera.main.WorldToScreenPoint (transform.position);
posX = Input.mousePosition.x - dist.x;
posY = Input.mousePosition.y - dist.y;
}
void OnMouseDrag()
{
Vector3 curPos = new Vector3 (Input.mousePosition.x - posX, Input.mousePosition.y - posY, dist.z);
Vector3 worldPos = Camera.main.ScreenToWorldPoint (curPos);
transform.position = worldPos;
}
}
Right now i have a button and upon clicking the button, i am able to instantiate a prefab at a location and then drag it from there. Can anyone please direct me as to how to make the system??

Hey,
I strongly recommend to use the dedicated event offer by Unity PointerEventData .
It's simpler and very quick to use, you can find some example on the web.
here mine :
public class PanelMouse : MonoBehaviour, IPointerClickHandler{
public GameObject toSpawn;
public void OnPointerClick(PointerEventData eventData)
{
GameObject spawned = Instantiate (toSpawn);
spawned.transform.position = Camera.main.ScreenToWorldPoint(eventData.position) + new Vector3(0,0,10);
Destroy (spawned,3f);
}
}
this script has to be used on the button or the collider of the gameobject??
