Strange probably silly error with arrays.

Here are some notes on IndexOutOfRangeException and ArgumentOutOfRangeException:

Steps to success:

• find which collection it is (critical first step!)
• find out why it has fewer items than you expect
• fix whatever logic is making the indexing value exceed the collection
• remember you might have more than one instance of this script in your scene/prefab

Regardless, what @MaskedMouse says is likely an issue:

Field initializers versus using Reset() function and Unity serialization:

Sensitivity in my MouseLook script.

Whatever value you set and save in your scene or prefab will wipe out the field initializer value you change in the code above. This is a common source of confusion: the object is created, so at that instant in time it has the value you set in code, but before the object is put into use, if Unity has a saved scene or saved prefab that this is already in, then the value saved is overwritten. It’s best to remove the initialization value above and instead provide it in a Reset function: public f…

If something is public: The instant you add that to your scene / prefab it is 10f … AND THEN IT GETS SERIALIZED. Now go change the value in code. Note that it has no effect: the serialized value writes over the code value. This is how Unity serialization works. If you want to define it in code, make the variable private. If you want to define it in the editor, make it public and DO NOT INITIALIZE IT. Instead, make a Reset function, which ONLY runs at the instant it is added: void Reset(…

Serialized properties in Unity are initialized as a cascade of possible values:

• what the class constructor makes (field initializers)

• what is saved with the prefab

• what is saved with the prefab override(s)/variant(s)

• what is saved in the scene and not applied to the prefab

• what is changed in Awake(), Start(), or even later etc.

So you want to make sure you only initialize things at ONE of the above levels, or if necessary, at levels that you specifically understand in your use case. Otherwise errors will seem very mysterious.
