Detailed Description

Class for managing Quake3 custom shaders.

Quake3 uses .shader files to define custom shaders, or Materials in Ogre-speak. When a surface texture is mentioned in a level file, it includes no file extension meaning that it can either be a standard texture image (+lightmap) if there is only a .jpg or .tga file, or it may refer to a custom shader if a shader with that name is included in one of the .shader files in the scripts/ folder. Because there are multiple shaders per file you have to parse all the .shader files available to know if there is a custom shader available. This class is designed to parse all the .shader files available and save their settings for future use. I choose not to set up Material instances for shaders found since they may or may not be used by a level, so it would be very wasteful to set up Materials since they load texture images for each layer (apart from the lightmap). Once the usage of a shader is confirmed, a full Material instance can be set up from it. Because this is a subclass of ScriptLoader, any files mentioned will be searched for in any path or archive added to the ResourceGroupManager::WORLD_GROUP_NAME group. See ResourceGroupManager for details.

Member Function Documentation

clear()

void Ogre::Quake3ShaderManager::clear

(

void

)

Clear all the current shaders.

create()

Quake3Shader * Ogre::Quake3ShaderManager::create

(

const String &

name

)

Create implementation.

getByName()

Quake3Shader * Ogre::Quake3ShaderManager::getByName

(

const String &

name

)

Retrieve a Quake3Shader by name.

getLoadingOrder()

Real Ogre::Quake3ShaderManager::getLoadingOrder ( void  ) const

virtual

Gets the relative loading order of scripts of this type.

Remarks

There are dependencies between some kinds of scripts, and to enforce this all implementors of this interface must define a loading order.

Returns

A value representing the relative loading order of these scripts compared to other script users, where higher values load later.

Implements Ogre::ScriptLoader.

getScriptPatterns()

const StringVector & Ogre::Quake3ShaderManager::getScriptPatterns ( void  ) const

virtual

Gets the file patterns which should be used to find scripts for this class.

Remarks

This method is called when a resource group is loaded if you use ResourceGroupManager::_registerScriptLoader.

Returns

A list of file patterns, in the order they should be searched in.

Implements Ogre::ScriptLoader.

getSingleton()

static Quake3ShaderManager & Ogre::Quake3ShaderManager::getSingleton ( void  )

static

Override standard Singleton retrieval.

Remarks

Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

getSingletonPtr()

static Quake3ShaderManager * Ogre::Quake3ShaderManager::getSingletonPtr ( void  )

static

Override standard Singleton retrieval.
