public fixed size array in inspector

I recently did this by using OnValidate() to check for size modifications and resetting the size to what I want it to be, while keeping the array contents:

 private const int SIZE = 5;
 public int[] ints = new int[SIZE];
 
 void OnValidate()
 {
     if (ints.Length != SIZE)
     {
         Debug.LogWarning("Don't change the 'ints' field's array size!");
         Array.Resize(ref ints, SIZE);
     }
 }

Only downside is, that when you have a second variable referencing the same array for whatever reason (like private int[] myInts = ints), the second variable still keeps the old array. But that's not something one usually does I guess.

I think you'd need to use a custom inspector. In DrawInspectorGUI, you'd have something like:

void OnInspectorGUI() { MyComponent myComp = target as MyComponent;

if you mean to rofbid possibility for users to change the size, I'd say use regular variables. But if you just want your array to appear in the inspector, you need built-in array :

var ColorAnimation : Color[] = new Color[5];

Then, in the inspector, you'll have :

ColorAnimation :
Size 5
Element 0 = Color
Element 1 = Color
Element 2 = Color
Element 3 = Color
Element 4 = Color

Hey everyone i know this is a very old Q/A but can someone help me in how can we set the array size by using script? i mean i know we can set it manually in inspector but i am working on something and it's size must be changed by script, any one help me?
