Beginner problems with C# (bool variable)

Hello,
I need to create an easy unity game and therefore code scripts with c#. Unfortunately I have absolutely no idea about programming.
So my task is to create a public bool variable on which is saved whether a created door is closed or open.
Additionally I have to code an if else statement to enable or disable the MeshRenderer and BoxCollider.
So I started doing something which is of course not working..
That's my code:


using UnityEngine;
using System.Collections;

public class Opendoor : MonoBehaviour
{
public bool offen;

void start()
{
offen = false;
}
void Update ()
{
if (offen == true)
{
this.GetComponent<BoxCollider>.enabled = true;
this.GetComponent<MeshRenderer>.enabled = true;
}
else
{
this.GetComponent<BoxCollider>.enabled = false;
this.GetComponent<MeshRenderer>.enabled = false;
}
}

I'd be very thankful if you could help me..

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Opendoor : MonoBehaviour
5. {
6.  
7. public bool offen;
8.  
9. private BoxCollider _boxcollider;
10. private MeshRenderer _meshRenderer;
11.  
12. void Awake()
13. {
14.     _boxCollider = GetComponent<BoxCollider>();
15.     _meshRenderer = GetComponent<MeshRenderer>();
16. }
17.  
18. void Update ()
19. {
20.     _boxCollider.enabled = offen;
21.     _meshRenderer.enabled = offen;
22. }
23.  

You can cache your components in private variables to make sure you don't have to call GetComponent every update and you can get rid of the "if" statement by setting "enabled" to whatever the current value of offen is.

 

Thank you very much!
Yours is working pretty well, but we have to use the "if" statement! It's for college purposes and our version isn't working..

 

Your if statement is correct, I think you're just missing your parenthesis after GetComponent<>()

 

thanksthanksthanks!

 

Btw please use this for your code.
