 |
|
Hello,
Yesterday I finished coding the 4-in-a-row game in delphi and decided to make it online.
I already started with the Server/Client and have done the Login-Part and chat-part.
But I do have some questions
1. Let's say, there is a playerlist, and every player who is logged in is listed there. So if someone closes the client the socket will disconnect and the server will remove the player from the list. But what if the player Terminates the client (by killing process ..) ? Then he will always be on the playerlist because he is not disconnecting correctly.
2. When the client sends a packet to the server then the server has to identify the client to know if it's john or peter, you know. So yet the client does send the player id in every packet, but that's very unsafe because of packet-editors. How should I handle that?
The source of the server and client are attached (w/o game). (Some people of the another forum helped me a bit so far)
MySQL data:
| Code: | /*
MySQL Data Transfer
Source Host: localhost
Source Database: 4gewinnt
Target Host: localhost
Target Database: 4gewinnt
Date: 17.05.2008 15:42:20
*/
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`ID` int(20) NOT NULL default '0',
`username` varchar(50) default NULL,
`password` varchar(50) default NULL,
`wins` int(20) default '0',
`loses` int(20) default '0',
`all_games` int(20) default '0',
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
-- ----------------------------
-- Records
-- ----------------------------
INSERT INTO `user` VALUES ('1', 'reak', 'test', '0', '0', '0');

Create a new thread for each user? then handle each user's packets in diffrent threads, so the ID isn't important.

Yes, someone else already told me this, I think I should use the indy-components :/

1: Set a time-out on receive and drop the player if you don't receive a packet.
