Require Component

Sometimes in script you require the object to have a certain component. This may be a rigidbody, text, box collider. Anything at all.
 
Sometimes when you try and use a component which isnt there a lot of errors/bugs and crashes can occur, which we all know is very frustrating.
 
Using the “RequireComponent” means you cant delete the component while this script is attached. Its awesome!
 
For example; Say we are manipulating the Text element of the UI.
 
At the top of the script. After the using and before the class we type
 
“ [RequireComponent(typeof(Text))] “
 
Like this.

 

This will now mean we cant remove the component in the inspector.
