The simple command console provides an easy to use dos-style command parser featuring commands, helps, and aliases.
The simple command console is ready to go right out of the box. Simply import the entity into your project, and add it to your screen. Then use the described public methods to add new commands, helps or aliases.
Registering Commands
This method is used to register a command. This defines the command and indicates what method should be called when the command is entered.
name is a string that represents the command to be typed. This can not contain any white space characters, as the command parser stops at the first white space when looking for a command to parse.
helpText is a string to be displayed to the screen if the user types "help name". This should describe how to use the command.
target is a delegate provided by the entity and is defined as:
The CommandTarget is the function to be called when this command is typed. If the user types anything after the command, the entirety of the line after the command is passed to the function as a single string. For instance, if the the command is "list" and the user types "list all my houses" then when the function is called it will be passed "all my houses" in the args variable.
Registering Command Aliases
This method allows you to register an alias for a previously registered command. An alias is another keyword that can be used instead of the commands name.
alias is a string that represents the new name of the command.
commandName is the name of the command to create an alias for.
Registering Helps
This method allows you to register help text that is not associated with a command. This should not be used to register helps for commands, as that help should be registered with the command itself.
name is a string that the user will type after the help command to retrieve this help entry.
helpText is a string that will be displayed to the screen when the user requests this help entry.
Registering Help Aliases
This method allows you to register an alias for a previously registered help entry. An alias is another keyword that can be used instead of the help entry's name.
alias is a string that represents the new name of the help entry.
helpName is the name of the original help entry to create an alias for.
Customization
The console window display can be customized using the various variables that have been exposed.
X,Y : sets the bottom left corner of the console window
Z : sets the z-buffer of the display so it can show up over other sprites
NumOutputLines : The number of output lines visible in full display mode
NumCharOnLine : The number of characters allowed on each line
CursorBlinkRate : How fast the cursor should blink, smaller number is faster blink
FullDisplay : if the console is currently in full display mode
NumLinesInPartialDisplay : how many lines should be shown while in partial display mode
InputHistoryLength : how many different inputs should it remember at once
BackBufferHistoryLength : the total number of lines to be stored in the backbuffer
In Game Usage
To issue a command in the game, type the command preceeded by a forward slash. For instance "/reset me" will call the function registered with the "reset" command, passing the argument of "me".
If you type your command without a forward slash like "reset me" the console will look to see if there is a "say" command registered, if so it will call the function registered with the "say" command and pass it the entirety of the typed input. This is the equivalent as if you typed "/say reset me". If no say command is registered, the console will tell the user that it did not recognize the command or keyword.
To get help on a topic or a command you can type "/help" followed by the topic or command that you want help on. For instance, if you wanted help on the "reset" command, you would type "/help reset", this same is true for non-command help.
If the command entered does not exist, the console will display a simple message saying that the command does not exist.
When in full mode, the console reads all input from the pc keyboard, and aside from certain special keys, all input is fed to the console display.
Special Keys
When in full display mode, the console watches for certain special keys that perform certain operations.
Additional Notes
If the output display is too wide for the console's settings, it will auto-wrap the output to the last available space between characters.
The console currently only accepts input from InputManager.Keyboard
The console is currently only built for Windows PC, inputs from other devices may or may not be recognized.
Internally, there is no difference between a command help or a non-command help. Once registered all help topics are stored by keyword and display text only.
