activating game objects with a tag

Question

I have this code

if (turretBaseID==true)
    {
        tb1.active=true;
        tb2.active=true;
        tb3.active=true;
        tb4.active=true;
        tb5.active=true;
        tb6.active=true;
        }

but instead of the the many lines of .active=true, is it possible to have a line writing any gameobject with the tag tb.active=true?

Yes. Use a for loop like this:

In C#:

public GameObject[] tbObjects;

for (int i = 0;i<tbObjects.Length;i++) {
    tbObjects[i].active = true;
}

In JS:

var tbObjects : GameObject[];

for(var i = 0;i<tbObjects.length;i++) {
    tbObjects[i].active = true;
}

This is assuming that your tb objects are references to GameObjects. If they're not, you can replace the array variable type with whatever object you are using. Populate the array with references to your tb objects in the Inspector. If that's not an option, let me know and I'll try to come up with an alternate solution if I have time.

Please note that above script examples are untested and report any errors accordingly.

I don't a lot of experience with arrays so bare with me. In the inspector of the objec the script is attached to it shows Tb Objects with a drop down showing size = 0. how do I reference this to the tb objects?

You need to set the size to the amount of objects you have (in your case, set 0 to 6), then drag each object into a slot that matches its number-1. Because arrays are zero-based (start counting on 0), you'll want to match up tb1 with position 0, tb2 with position 1, tb3 with position 2, etc.

Thanks that has got it working and showing it as active, but when I try to get in as active = false it keeps showing as active.

Replace the tbObjects[i].active = true; line with tbObjects[i].active = false; and it should work. :)
