What am I doing wrong here?

Hi,
Why would the first for set up record the positions I want, however the second for enemy, does not record any positions?

Code (csharp):

1.  
2. #pragma strict
3. var heroObjectArray : Array;
4. var heroObject : GameObject[];
5. var enemyObjectArray : Array;
6. var enemyObject : GameObject[];
7. var heroObjectPos : Vector3[];
8. var enemyObjectPos : Vector3[];
9.  
10. function Start () {
11.    
12.     heroObjectArray  = new Array(heroObject);  
13.     enemyObjectArray  = new Array(enemyObject);    
14.    
15.     for(var b : int = 0; b <= heroObjectArray.length; b++)
16.     {
17.         ///record all positions of b objects.
18.         heroObjectPos[b] = heroObject[b].transform.position;
19.     }
20.     for(var d : int = 0; d <= enemyObjectArray.length; d++)
21.     {
22.         ///record all positions of d objects.
23.         enemyObjectPos[d] = enemyObject[d].transform.position;
24.     }  
25. }
26.  

 

Are you sure that enemyObject[] has any entries at all? It wouldn't make sense for the code not to work, since it is identical to the one that works. Something must be wrong with the second array.

 

Yes. It has 8 members all assigned.

When i check the inspector, after start, the heroObjectPos array is filled. The enemyObjectPos array has all vector0 values.

Not sure.

 

Ok, I am finding this very frustrating.

I have a question tho which hopefully can provide some insight.

Code (csharp):

1.  
2. var heroObjectArray : Array;
3. var heroObject : GameObject[];
4. var enemyObjectArray : Array;
5. var enemyObject : GameObject[];
6. var heroObjectPos : Vector3[];
7. var enemyObjectPos : Vector3[];
8. var heroObjectManager : GameObject;
9. var heroObjectManagerData : heroManagerScript;
10.  
11. function Start () {
12.    
13.     heroObjectManagerData = heroObjectManager.GetComponent(heroManagerScript);
14.     while (heroObjectManagerData.settingScene == true)
15.     yield;
16.    
17.     heroObjectArray  = new Array(heroObject);  
18.     enemyObjectArray  = new Array(enemyObject);    
19.    
20.     for(var b : int = 0; b <= heroObjectArray.length; b++)
21.     {
22.         print("b " + b);
23.         ///record all positions of b objects.
24.         heroObjectPos[b] = heroObject[b].transform.position;
25.     }
26.     for(var d : int = 0; d <= enemyObjectArray.length; d++)
27.     {
28.         print("d " + d);
29.         ///record all positions of d objects.
30.         enemyObjectPos[d] = enemyObject[d].transform.position;
31.     }  
32. }
33.  

my print outs for "b" always go one value over the size.

I get the error that the array for b is out of range.



Why would that be?

 

Never use <= in conjunction with lenght. The lenght of an array is always higher -- in an n element array, the elements are indexed from 0 to n-1

 

You need to learn basic scripting. Once you learn this, then you will know about zero-based arrays and what will happen when accessing the [length] element.

 

Thanks.
