How do you move an object in Arkit with script?

sexypreneur opened this issue · 1 comments

changing transform doesn't work. Do you have any idea?

Move my gameObject up from existing position in AR world but none of it works.

I'm trying to do transform.DOMove(....) to move the gameObject up AR World. I also tried changing the localposition

But none of that works. Object ie. prefab stays at same position.

How do we move the object that's instantiated in AR World?

I have commented the code in which I'm also directly modifying the transform but doesn't work either.

DOTween is free Tweening package to Tween an Object

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.iOS;
using DG.Tweening;
using UnityEngine.UI;

public class TestHitControl : MonoBehaviour {

	public GameObject obj;
	private UnityARSessionNativeInterface m_session;

	// Use this for initialization
	void Start () {
		DOTween.Init(false, true, LogBehaviour.ErrorsOnly);
		m_session = UnityARSessionNativeInterface.GetARSessionNativeInterface ();
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.touchCount > 0) {
			if (Input.GetTouch (0).phase == TouchPhase.Began) {
				createGameObject ();
			}
		}
	}

	void createGameObject(){
		Vector3 screenPos = Camera.main.ScreenToViewportPoint (Input.GetTouch (0).position);
		ARPoint point = new ARPoint{ x= screenPos.x,y=screenPos.y };

		ARHitTestResultType[] resultTypes = {
			ARHitTestResultType.ARHitTestResultTypeExistingPlaneUsingExtent, 
			// if you want to use infinite planes use this:
			//ARHitTestResultType.ARHitTestResultTypeExistingPlane,
			ARHitTestResultType.ARHitTestResultTypeHorizontalPlane, 
			ARHitTestResultType.ARHitTestResultTypeFeaturePoint
		}; 

		foreach (ARHitTestResultType resultType in resultTypes)
		{
			List<ARHitTestResult> hitResults = m_session.HitTest (point, resultType);
			if (hitResults.Count > 0) {
				GameObject currentObj = GameObject.Instantiate (obj);
				
				currentObj.transform.position = UnityARMatrixOps.GetPosition (hitResults [0].worldTransform);
				currentObj.transform.rotation = UnityARMatrixOps.GetRotation (hitResults [0].worldTransform);
				currentObj.transform.LookAt (new Vector3(Camera.main.transform.position.x, currentObj.transform.position.y, Camera.main.transform.position.z));
				
				myText.text = currentObj.transform.position.ToString(); 

				StartCoroutine(SlideUp(currentObj)); 

				//new WaitForSeconds(10f);
				//obj.transform.DOMove(currentObj.transform.position + (Vector3.up * 100), 10); 
			}
		}
	}

	IEnumerator SlideUp(GameObject currentObj) {
		yield return new WaitForSeconds(1f);
		obj.transform.DOMove(currentObj.transform.position + (Vector3.up * 100), 10);
	}
}

Hi, I haven't commit some core source files in the previous version, that's could cause the project doesn't work. I'm really sorry about that.

I have just fixed the problem and add the missing file, and you could download the updated version to try the new feature.

Thank you very much.
