How do I get each GameObject to mind its own business?
Hi Guys,
Pretty new to programming here.. I have created a script to generate things that stack. Such as Trees or Towers. My plan is to put 1 base item down, it will stack X amt of mid sections on top of it, and place a topper on it when its done.
So far this works, but only if I have GameObject using the script at a time. If I try to add more GameObjects using the same script, they all just build off of 1 starting point on top of each other!!
How do I get these GameObjects to do their own thing? Have a look at my script. Thanks!
public GameObject[] basePiece;
public GameObject[] midPiece;
public GameObject[] topPiece;
public int _height = 1;
public int maxHeight = 20;
public int minHeight = 1;
public bool isTree = false;
public bool isTower = false;
public float treeTilt = 0.0f;
public GameObject curSpawnPoint;
public GameObject curObject;
void Awake () {
curObject = this.gameObject;
if(isTower)
SpawnTower();
if(isTree)
SpawnTree();
}
public void SpawnTower(){
if ( minHeight < 1 ){
minHeight = 1;
}
if ( maxHeight > 20 ){
maxHeight = 20;
}
_height = Random.Range(minHeight, maxHeight + 1);
curSpawnPoint = GameObject.Find("spawnPoint");
for (int cnt = 0; cnt < _height; cnt++){
GameObject go = Instantiate(midPiece[Random.Range(0, midPiece.Length)],
curSpawnPoint.transform.position,
curSpawnPoint.transform.localRotation
) as GameObject;
go.transform.parent = curSpawnPoint.transform;
curObject = go;
curSpawnPoint = curObject.transform.Find("spawnPoint").gameObject;
}
GameObject goTop = Instantiate(topPiece[Random.Range(0, topPiece.Length)],
curSpawnPoint.transform.position,
curSpawnPoint.transform.localRotation
) as GameObject;
goTop.transform.parent = curSpawnPoint.transform;
}
Gave you a upvote for a hilarious question title that grabs my attention.
haha thanks Chronos. gotta draw attention to my plea somehow.
How sure are you that different gameObject are building on the same tower?
From your code (which I did not run and test yet), you are spawning the tower in one spawn point. (`curSpawnPoint = GameObject.Find("spawnPoint");`)
Is it possible that your code is working, but all the tower are built in the same spot, hence creating the illusion of "gameObject sticking into another gameObject's business"?
I might not have been clear enough, but they are in fact all starting from the same Vector 3. Not that they are building on top of each other in the Y direction. They do all share the same X and Z coordinate starting point.
For example, I found out about my problem when I started using the script to build trees from sectional pieces I made in Blender. I put down 3 base tree pieces at 3 separate locations. Added my script to each of em and hit play. 2 of the stumps have nothing growing on em, 1 of em has 3 trees of random height growing from the same spot.
I had a suspicion this had something to do with static variables? I don't quite understand them but after reading documentation on them, I don't think its what I want. I always use private/public.
I should add that each of the trees are children of 1 stump. That's good info to know.

I think I get what you mean clear enough. It is exactly because your tower starts from the same Vector3, then you get this problem. I did not say they build on top of each other, they are building themselves using the same space.
You want to get towers with random height I draw these horizontally, this is what you are expecting:
[ ] tower 1
( ) tower 2
O tower 3
//------ this direction is y-axis -------------->
[ ][ ][ ][ ]
( ) ( ) ( ) ( ) ( ) ( ) ( )
O O O
However, since they start on the same location, what you will get is:
//------ this direction is y-axis -------------->
[(O)][(O)][(O)][( )] ( ) ( ) ( )
Your tower is doing the impossible: sharing the same physical space. I think this is what happens to your code.
You need to fix this part curSpawnPoint = gameObject.Find("spawnPoint"); . You should do some calculation to offset the position of your spawnPoint gameObject everytime you spawn a new tower.
Fix this one and your code should be okay, I see no other problem with your code.
You know what, since I have some spare time right now, I will set up the scene and run this code to check my hypothesis. Be back soon.
I ran the code. It works fine when there is one towerBuilder object. However, when there's more than one towerBuilder object. Here's what happen:
The script do create 3 tower, but they are all in the same location. (Please note the hierarchy view, the spawnPoint has 3 children)
When I move the towers around,
So, all the towers are correctly built. Just that they are all built in the same location.
