What (in your opinion) do you think is the hardest part of coding a game? I think its the AI but i havent made mine in Lite-C quite yet, but with basic and C# its not too easy.

You cannot say part X is the hardest part of a programming a game. It totally depends on the type of game you want to create. For a first person shooter the scene and object managment are quite hard to do as well as the A.I. For a puzzle game maybe the content loading system and level generation might be the hardest things.

However, how does this refer to Lite-C?

Im just wandering what you think is the toughest part of coding with lite-c is

There's no hardest part at all. The difficulty is to connect all parts and to keep track of them.

well everyone knows in their project there is one part they are dreading to code.

The hardest part to code, is the very last line of code.
Finishing a game is always the hardest part. Everything in between is just the struggle to get there.

My biggest battle was getting all events right. There was such a lot misbehaviour which was complicated to find out, so I have highest respect of events.

Especially when thinking of multiplayer just the plain thought of it makes me run away...
