Notify this manager that a resource which it manages has been loaded.

Notify this manager that a resource which it manages has been 'touched', i.e.
used.
|
virtual |
Notify this manager that a resource which it manages has been unloaded.
|
virtual |
Create a new resource, or retrieve an existing one with the same name if it already exists.
|
virtual |
Creates a new blank resource, but does not immediately load it.
name | The unique name of the resource |
group | The name of the resource group to attach this new resource to |
isManual | Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required. |
loader | Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended. |
createParams | If any parameters are required to create an instance, they should be supplied here as name / value pairs |
void Ogre::ResourceManager::destroyAllResourcePools | ( | ) |

Generic load method, used to create a Resource specific to this ResourceManager without using one of the specialised 'load' methods (containing per-Resource-type parameters).
name | The name of the Resource |
group | The resource group to which this resource will belong |
isManual | Is the resource to be manually loaded? If so, you should provide a value for the loader parameter |
loader | The manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter |
loadParams | Optional pointer to a list of name/value pairs containing loading parameters for this type of resource. |
backgroundThread | Optional boolean which lets the load routine know if it is being run on the background resource loading thread |
|
inlineoverridevirtual |
Parse the definition of a set of resources from a script file.
stream | Weak reference to a data stream which is the source of the script |
groupName | The name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it. |

inline |
Caused all currently loaded resources to be reloaded.
reloadableOnly | If true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later. |
