Problem With Raycast Pickup Using Touch
So I have this script attached to my Character Controller to pickup objects with the "Pickupable" script attached to them.
using UnityEngine;
using System.Collections;
public class PickupObject : MonoBehaviour {
GameObject mainCamera;
bool carrying;
GameObject carriedObject;
public float distance;
public float smooth;
// Use this for initialization
void Start () {
mainCamera = GameObject.FindWithTag("MainCamera");
}
// Update is called once per frame
void Update () {
if(carrying) {
carry(carriedObject);
checkDrop();
//rotateObject();
} else {
pickup();
}
}
void rotateObject() {
carriedObject.transform.Rotate(5,10,15);
}
void carry(GameObject o) {
o.transform.position = Vector3.Lerp (o.transform.position, mainCamera.transform.position + mainCamera.transform.forward * distance, Time.deltaTime * smooth);
}
void pickup() {
if(Input.GetMouseButtonDown(0)) {
Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch(0).position);
RaycastHit hit;
if(Physics.Raycast(ray, out hit)) {
Pickupable p = hit.collider.GetComponent<Pickupable>();
if(p != null) {
carrying = true;
carriedObject = p.gameObject;
p.gameObject.rigidbody.isKinematic = true;
}
}
}
}
void checkDrop() {
if(Input.GetMouseButtonDown(0)) {
dropObject();
}
}
void dropObject() {
carrying = false;
carriedObject.gameObject.rigidbody.isKinematic = false;
carriedObject = null;
}
}
I'm using Unity's built-in first person touch controller to navigate.
I can pick up the object properly as intended as I just touch on the object in front and it immediately starts hovering in front of me just like how I want, but the problem comes when I try to touch any of the navigation pads as the cube just drops all of a sudden. I want to make it so that the cube only gets dropped when I specifically touch it. How do I do that?

Can you just add another collision detection to your checkDrop function , like you have in your pickup() function? Only drop if collision is detected.
