attleshipAI.cs(65,90): error CS0176: Static member `battleshipSide.Underattack' cannot be accessed with an instance reference, qualify it with a type name instead

I don't understand why i can't accesses the script on the game object, using get component of the game object i want to change a bool to true on that game object sop my other ships cannot target the same ship.

some reason I'm getting this: BattleshipAI.cs(65,90): error CS0176: Static member `battleshipSide.Underattack' cannot be accessed with an instance reference, qualify it with a type name instead
