Setting up the MySql Database

You should have access to a database, I will refer to the database simply as database, and call the tables by their given names.

If we take a short moment to contemplate what we need, we will discover our data needs arent that big at all. A short analasys will point out we need the following tables with info:

players : Unique ID code, locations (x,y), angle, state (alive/dead) and lets keep track of kills/killed.

shotsfired : Who shot, who needs to know who shot, when was the shot made, what was the shot angle.

messages : Making game information available to everyone

Giving it a bit more definition:

(tablename)

(column name) - (column type)

Table players:

id - int(11) - primary index, auto increment

playercode - varchar (32)

locx - float

locy - float

playerangle - float

State - varchar(5)

kills - int (11)

killed - int(11)

Table shotsfired:

id - int(11) , primary index, auto increment

shootercode - varchar(32)

playercodes - varchar(32)

angle - float

stamped - Timestamp - default: CURRENT_TIMESTAMP

Table messages:

id - int(11) , primary index, auto increment

playercodes - varchar (32)

message - TEXT

stamped - Timestamp - default: CURRENT_TIMESTAMP

MySql for players table creation:

    CREATE TABLE IF NOT EXISTS `players` (  `id` int(11) NOT NULL AUTO_INCREMENT,  `playercode` varchar(32) NOT NULL,  `locx` float NOT NULL,  `locy` float NOT NULL,  `playerangle` float NOT NULL,  `state` varchar(5) NOT NULL,  `kills` int(11) NOT NULL,  `killed` int(11) NOT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

MySql for shotsfired table creation:

    
    CREATE TABLE IF NOT EXISTS `shotsfired` (  `id` int(11) NOT NULL AUTO_INCREMENT,   `shootercode` varchar(32) NOT NULL,  `playercodes` varchar(32) NOT NULL,  `angle` float NOT NULL,  `stamped` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
    

MySql for messages table creation:

    CREATE TABLE IF NOT EXISTS `messages` (  `id` int(11) NOT NULL AUTO_INCREMENT,  `playercodes` varchar(32) NOT NULL,  `message` text NOT NULL,  `stamped` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;    

Those are the tables, simple huh.

If you have added these tables, we are good to go to set up the php side of things.
