Member Function Documentation
|
Send the csevSystemClose command to all loaded plugins.
|
|
Create the commandline parser. This function will register the created commandline parser with the object registry as the default parser (using 0 tag). |
|
Create the config manager. This function will register the created config manager with the object registry as the default config manager (using 0 tag). |
|
Create everything needed to get a CS application operational. This function is completely equivalent to calling:
You may want to call all or some of those manually if you don't wish to use this function. It is suggested that CS_INITIALIZE_PLATFORM_APPLICATION, InitializeSCF(), and csPlatformStartup() are always invoked; the other calls can be replaced with manual creation of the respective objects. However, the order above should be retained when doing so.
|
|
This essential function creates the event queue which is the main driving force between the event-driven CS model. In addition this function will register the created event queue with the object registry as the default event queue (using 0 tag). |
|
This function will create the three common input drivers (csKeyboardDriver, csMouseDriver, and csJoystickDriver) and register them with the object registry. Note that this function must be called after creating the config manager (CreateConfigManager()). |
|
This function should be called second. It will create the object registry and return a pointer to it. If there is a problem it will return 0. |
|
You will almost certainly want to call this function. It will create the plugin manager which is essential for nearly everything. The created plugin manager will be registered with the object registry as the default plugin manager (using 0 tag). |
|
Create the global shared string set and register it with the registry. This can be used if multiple, distinct modules want to share string IDs. The set can be requested with: csRef<iStringSet> strings = CS_QUERY_REGISTRY_TAG_INTERFACE ( object_reg, "crystalspace.shared.stringset", iStringSet); |
|
Create and, if needed, register the verbosity manager. It is used by a lot of plugins to control diagnostoc output while running. |
|
Create the virtual clock. This clock is responsible for keeping track of virtual time in the game system. This function will register the created virtual clock with the object registry as the default virtual clock (using 0 tag). |
|
Destroy the application. Undo all of the initialization done by CreateEnvironment() or any of the other setup functions.
|
|
The default application string name; computed from the executable name as passed in argv[0] to CreateEnvironment(). If the latter was not called or argv[0] did not contain a sensible name, a default string is used. Referenced by csApplicationFramework::GetApplicationName(). |
|
This very important function initializes the SCF sub-system. Without this you can do almost nothing in CS. |
|
Send the csevSystemOpen command to all loaded plugins. This should be done after initializing them (Initialize()). Referenced by csApplicationFramework::Open(). |
|
Request a few widely used standard plugins and also read the standard configuration file and command line for potential other plugins. This routine must be called before Initialize(). Unlike the variable-argument RequestPlugins(...) method which expects you to know the list of requested plugins at compile-time, this overload allows you to construct an array of plugins at run-time. You do this by constructing a csArray<> of csPluginRequest records. For example: csArray<csPluginRequest> a; a.Push(csPluginRequest(CS_REQUEST_VFS)); a.Push(csPluginRequest(CS_REQUEST_ENGINE)); a.Push(csPluginRequest(CS_REQUEST_PLUGIN("myproj.foobar",iFoobar))); csInitializer::RequestPlugins(registry,a); |
|
Request a few widely used standard plugins and also read the standard configuration file and command line for potential other plugins. This routine must be called before Initialize(). The variable arguments should contain four entries for every plugin you want to load: SCF class name, SCF interface name, inteface ID, and interface version. To make this easier it is recommended you use one of the CS_REQUEST_xxx macros above. WARNING Make sure to end the list with CS_REQUEST_END! |
|
This is just like RequestPlugins(. ..), which accepts a variable list of arguments at compile-time, except that arguments are passed as a `va_list'. |
|
Setup the config manager. If you have no config file then you can still call this routine using a 0 parameter. If you don't call this then either RequestPlugins() or Initialize() will call this routine with 0 parameter. The 'ApplicationID' parameter is used to determine the correct user-specific domain; if 0, the return value of GetDefaultAppID() is used. It is possibly overriden by the application config file option "System.ApplicationID". This method will load the VFS plugin if not already present in the given object registry. Referenced by csApplicationFramework::SetupConfigManager(). |
|
Initialize an event handler function. This function will receive EVERY event that passes through the system. This is usually not what you want, since (1) it means you'll probably receive a lot of events you're not interested in, and (2) it's the most costly operation for the event subscription scheduler. |
|
Initialize an event handler function. This is an easier version of SetupEventHandler() that takes a function and will register an event handler to call that function for all stated events and their children, or (if the third argument is omitted) for all events. |
|
Initialize an event handler for the application. This is the most general routine. This event handler will receive all events that are sent through the event manager. Use this function to know about keyboard, mouse and other events. Note that you also have to use this function to be able to render something as rendering happens as a result of one event (csevProcess). |
|
Find or load the VFS plugin, add it to the given object registry, and return it. An alternate plugin ID for VFS may be given as well. Use this method if you need to make changes to VFS, or use an alternate VFS plugin, before calling SetupConfigManager. Otherwise, SetupConfigManager will load the default VFS plugin automatically. objectReg can be the object registry object returned by CreateEnvironment, or one that you have manually set up with plugin and config manager objects. |
