How to disable the event trigger method programmatically ??

Questions & Answers
1

I am working on game in which user can drag objects to desire position. After dropping at desired position
I want to disable the onDrag method. But I am unable to achieve this functionality. Kindly help me!

Thanks in Advance.

public void OnDrag() 
{
	Vector3 pos = Camera.main.ScreenToWorldPoint (Input.mousePosition);
	pos.z = 0;
	gameObject.transform.position = pos;

	if(isNearToDesiredPos())
		enabled = false;
}

Note: “isNearToDesiredPos” is returning true on desired position.

You can’t unregister it as it is done internally. you can prevent running the code.

public void OnDrag() 
 {
    if(isDropped) return;
     Vector3 pos = Camera.main.ScreenToWorldPoint (Input.mousePosition);
     pos.z = 0;
     gameObject.transform.position = pos;
 
     if(isNearToDesiredPos())
         enabled = false;
 }

isDropped is set when you drop the object. I would guess it might go with enabled = false;

I know maybe is too late. But it would be the best solution.
If the Button or Gameobject has an image component you can use:

.GetComponent<Image>().raycastTarget = boolValue

as you want like button.interactable = boolValue.

Using This
GetComponent().enabled=true;
