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

◆ 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.

◆ parseScript()

void Ogre::Quake3ShaderManager::parseScript ( DataStreamPtr stream,
const String groupName 
)
virtual

Parse a script file.

Parameters
streamWeak reference to a data stream which is the source of the script
groupNameThe name of a resource group which should be used if any resources are created during the parse of this script.

Implements Ogre::ScriptLoader.

◆ 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.

◆ create()

Quake3Shader* Ogre::Quake3ShaderManager::create ( const String name)

Create implementation.

◆ clear()

void Ogre::Quake3ShaderManager::clear ( void  )

Clear all the current shaders.

◆ getByName()

Quake3Shader* Ogre::Quake3ShaderManager::getByName ( const String name)

Retrieve a Quake3Shader by name.

◆ getSingleton()

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

Get the singleton instance.

◆ getSingletonPtr()

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

Get the singleton instance.
