Command Module notes

From the The Orx Bounce Demo, or any of your own games, you can bring up the Orx Console with tilde (~).

Command.ListCommands lists all commands Command.ListCommands <prefix> filters list by prefix.

e.g. Command.ListCommands Config only shows commands for the config module

Command.Help <command> shows how to use a command.

- Executing a command directly from code:

orxCOMMAND_VAR stResult; 
orxCommand_Evaluate("Object.Create RedCar", &stResult);

stResult.u64Value will contain the GUID of the created object.

Of course the string can be loaded from config for something more data-driven.

Core Commands

These commands are registered by the Orx system automatically. See below for the macro orxCOMMAND_REGISTER_CORE_COMMAND that registers these commands.

To register your own commands, write a similar macro or register your command with orxCommand_Register.

extern orxDLLAPI orxSTATUS orxFASTCALL orxCommand_Register(const orxSTRING _zCommand,
                                                           const orxCOMMAND_FUNCTION _pfnFunction,
                                                           orxU32 _u32RequiredParamNumber,

                                                           const orxCOMMAND_VAR_DEF *_astParamList,
                                                           const orxCOMMAND_VAR_DEF *_pstResult);

Timeline

Timelines allow for executing commands from the command module in config.

You can ask to push the result of a function as many time as you want but make sure to have the same numbers of push and pop, as usual for a stack.

Here are the current special characters:

" is used as a block delimiter, exactly in the same way as in config
> is used for pushing the result of a command and has to be typed before the command
< is used for poping an element from the stack
^ is used to replace an argument by the GUID of the timeline's owner object

Now, if you want to use commands + timelines, let's say for creating a Timer object that will play the beep sounds before a race starts.

In config:

; Object template
[Timer] 
TrackList = BeepTrack 
 
; TimeLineTrack template
[BeepTrack] 
0 = Object.AddSound ^ RegularBeep 
1 = Object.AddSound ^ RegularBeep 
2 = Object.AddSound ^ HighPitchBeep 
3 = Object.Delete ^ 

In code, create the “Timer” object and the timeline is added to it immediately on creation.

Currently, this is the timeline track template (from CreationSettings.ini):

[TimeLineTrackTemplate]
[Float] = "Your timeline event text here" | "Your command"; NB: Float is a time in second (>= 0) after which this timeline event is going to be triggered; If the event is a valid command it'll get executed by the command module;
Loop = true|false;
KeepInCache = true|false; NB: If true, the timeline track will always stay in cache, even if no track of this type is currently in use. Can save time but costs memory. Defaults to false;
