Hello everybody!

I am beginning to develop games and decided to start with "Pong", since it is one of the simplest games out there. After reading some topics in this forum I decided it would be a good idea to create a topic for me to expose my source and discuss the decisions I made and the doubts I have.

I'll post the source sometime this week, but I'll already raise a question I have:

1) Components and Enums/Constants

In my current implementation, I have a component called AI that mark that a paddle is controlled by the computer. This component also have a field called difficulty indicating the algoritm the AI should use. For example, passive means the paddle should not move at all, while invincible means the AI never miss the ball (I have some "normal" AIs too, like "easy" and "hard", but those others are only for test/example).

So I was thinking about a system called AISystem that take all entities with the AI component, read the difficulty field and decides which algoritm to use. But then I had a doubt: it is a good design to declare an enum inside my AI component (and therefore declare the difficulty field with this type) to ensure it would be set with a valid value, or I am overloading the responsabilities the component should have? Should I place some constants somewhere else (like a Constants class) and don't suppose the component should know every possible value of his difficulty field?

I don't see a problem with declaring an enum in a component. I would probably have chosen the same solution myself. That way you have the declaration where it's used.
