Scratch

I've been playing around with panther a bit and searching through the forums, as well as looking at a few other multiplayer games' code, and with that knowledge I decided to make my own. Block Catch Online, a game based off of duck hunt where a block flies around the screen, and you must be the first one to catch it.

The system goes like this: (Created in panther)

I've made a client, and a registration project that will give you a username and password (if the username does not exist) and then you can use your username and password to log into the game with a client. The server is started and a blue block bounces off a server. The block records it's X and Y into variables, and another sprite in the client to represent the block goes to the same position as the server block, therefore everyone will have the same block velocity and position. Once somebody clicks their block, a broadcast is sent to the server. The server block receives the clicked broadcast and resets it's position and velocity likewise, and then it sends back a broadcast telling the clients they can click it again.

Problems:

(Hopefully WILL be solved.) Once I connect a second client with a different username, the entire game, all servers and clients, freeze. I think it's because I'm connecting more than one on one computer, mine. I can't necessarily release it because of the problems below.

(Hopefully Solved) Hackers. They can easily make it so the block follows their cursor and they can never miss. I've been thinking about a server-sided solution where it would check to see if the mouse was a certain distance from the block, but of course because of the slowness the judgements wouldn't be accurate. The only way to fix this is .exe compiling.

(Unsolved, but unimportant.) Spam. I've added a chat feature, and I have no way of preventing spam. I've tried to use the timer to check if there has been 1 second between messages, but then if two people entered in a chat message at once, only one would show up, and the conversation would be one-sided.

Until I can fix these problems, I'll have to put the release on hold.

...Too late. :3
