SetActive False Multiple GameObjects

Hello,
Similar setup as Unity's Roll-A-Ball project where you destroy cubes when you roll the ball.
The next time when you start a game how do you SetActive=False the cubes that are already collected?
Without creating 100-200 "if" statements like below?

Note: I already setup enum on another script where it sets cube1=true.

Code (CSharp):

1. public List<GameObject> myObjects = new List<GameObject>();
2. void Start()
3.     {
4. if (cube1 == true)
5.         {
6.             myObjects[0].SetActive(false);
7.         }
8. if (cube2 == true)
9.         {
10.             myObjects[1].SetActive(false);
11.         }
12. ...............................
13. }

 

Instead of having separate variables like cube1, cube2, etc., create a List to hold all of those values. Then you can use a loop to iterate over the whole list, and modify

myObjects[i]

based on the value of

cube[i]

Any time you find yourself creating variables whose names end in 1, 2, etc. that almost always means you should be using a List instead.

 

Thank you. I can’t wrap my head around using for loop to filter out the specific objects.

I have 550 cubes and I want to filter out only the cubeOrange, cubeBlue, cubeGreen etc and set them as SetActive false

for (int i = 0; i = 550; i++) {
//Stuff
}

and without using game Tags. Is it possible?

 

Add some other identifier to the objects then. Check for that identifier, and act on it. For example, it could be a public variable on a script attached to the objects.

 

The closest thing to the code in your OP would be something like

Code (CSharp):

1. for (i = 0; i < myObjects.Count; ++i)
2. {
3.     if (cube[i] == true) myObjects[i].SetActive(false);
4. }

Though notice that that loop never calls SetActive(true) on anything. If you want to make it so that the cubes with 'true' bools become inactive and all the rest become active, you could change that to

Code (CSharp):

1. for (i = 0; i < myObjects.Count; ++i)
2. {
3.     myObjects[i].SetActive(!cube[i]);
4. }

Both of those assume that you've already got a bool variable for every single cube, and the values are controlled by some other code somewhere. That's one possible way of doing things.

Another approach would be to have a list of just the cubes you want to remove; e.g.

List<GameObject> cubesToRemove;

And then your loop might look more like

Code (CSharp):

1. for (i = 0; i < myObjects.Count; ++i)
2. {
3.     myObjects[i].SetActive(!cubesToRemove.Contains(myObjects[i]));
4. }

The best way to organize your data will depend on how that data is being generated or updated.

 

Thank you for the answers. I was also looking into using Enums and it allowed me to get results I wanted. Something like this.

Code (CSharp):

1. public enum ItemsBricks
2.                      {
3.                          cube1, cube2.........................etc
4.                      }
5.  
6.    void checkForDestroyedBricks(ItemsBricks state)
7.    {
8.        if (state == ItemsBricks.cube1)
9.         {
10.             this.gameObject.SetActive(false);
11.         }
12.    }
