[SOLVED] foreach statement cannot operate on variables of type 'BoxCollider'

Hello,

I am trying to create a code that selects multiple object units in my scene whenever I drag my mouse across them. However, I am getting this error:

{
"resource": "/c:/Users/Zach/RTSTest/Assets/Scripts/PlayerManager.cs",
"owner": "csharp",
"code": "CS1579",
"severity": 8,
"message": "foreach statement cannot operate on variables of type 'BoxCollider' because 'BoxCollider' does not contain a public instance definition for 'GetEnumerator' [Assembly-CSharp]",
"source": "csharp",
"startLineNumber": 63,
"startColumn": 37,
"endLineNumber": 63,
"endColumn": 68
}


I am not sure what I've done wrong. I am very new to this. Here is the code itself, let me know if you need more to see.

Also, if you know a way to maybe make this work more efficiently I am open to hearing those suggestions. I doubt selecting units this way is good.

Code (CSharp):

1. if(Input.GetMouseButtonUp(0))
2.     {
3.             if (isDragging)
4.         {
5.                 DeselectUnits();
6.                 foreach(var selectableObject in FindObjectOfType<BoxCollider>())
7.             {
8.                 if(isWithinSelectionBounds(selectableObject.transform))
9.                 {
10.                     SelectUnit(selectableObject.transform, true);
11.                 }
12.             }
13.         }
14.          
15.             isDragging = false;
16.     }

 

You are calling

FindObjectOfType

, which returns only a single object, as the name implies.

What you are looking for is

FindObjectsOfType

Change "FindObjectOfType<BoxCollider>()" to "FindObjectsOfType<BoxCollider>()".

 

Ahh, jeez. I miss the tiniest things, thank you.

 

smallest problems and I miss it lol yikes. Thank you.
