using UnityEngine;
using System.Collections;
public class MakeTwoPoints3D : MonoBehaviour {
public GameObject cylinderPrefab;
// Use this for initialization
void Start () {
CreateCylinderBetweenPoints(Vector3.zero, new Vector3(10, 10, 10), 0.5f);
}
void CreateCylinderBetweenPoints(Vector3 start, Vector3 end, float width)
{
var offset = end - start;
var scale = new Vector3(width, offset.magnitude / 2.0f, width);
var position = start + (offset / 2.0f);
Object cylinder = Instantiate(cylinderPrefab, position, Quaternion.identity);
cylinder.transform.up = offset;
cylinder.transform.localScale = scale;
}
// Update is called once per frame
void Update () {
}
}
On both lines same error:
cylinder.transform.up = offset;
cylinder.transform.localScale = scale;
Severity Code Description Project File Line Suppression State Error CS1061 'Object' does not contain a definition for 'transform' and no extension method 'transform' accepting a first argument of type 'Object' could be found (are you missing a using directive or an assembly reference?) MakeTwoPoints3D.cs 23 Active
Object
is parent class of GameObject
and GameObject
as member of type Transform
. If you try to access transform
from an instance of Object
class, it will show you following error:
Object' does not contain a definition for 'transform'
So accurate way of instantiating and using the resulted object as a GameObject is as Quantic said in comment :
GameObject cylinder = Instantiate(cylinderPrefab, position, Quaternion.identity) as GameObject;
OR
GameObject cylinder = (GameObject) Instantiate(cylinderPrefab, position, Quaternion.identity);
It is always to use null-check for safety before using the component in case of other types than GameObject. For example:
Rigidbody rb = Instantiate(somePrefab) as Rigidbody;
if(rb != null)
// use it here
hope this helps.
