const plDynamicArray< plSurfaceResourceHandle > & GetSurfaces () const
 Returns the array of default surfaces to be used with this mesh.
 
bool HasTriangleMesh () const

 Creates a new instance (shape) of the triangle mesh.
 
plUInt32 GetNumConvexParts () const
 Returns the number of convex meshes. Triangle meshes and convex meshes are mutually exclusive.
 
JPH::Shape * InstantiateConvexPart (plUInt32 uiPartIdx, plUInt64 uiUserData, const plJoltMaterial *pMaterial, float fDensity) const
 Creates a new instance (shape) of the triangle mesh.
 
plCpuMeshResourceHandle ConvertToCpuMesh () const
 Converts the geometry of the triangle or convex mesh to a CPU mesh resource.
 
plUInt32 GetNumTriangles () const
 
plUInt32 GetNumVertices () const
 
- Public Member Functions inherited from plResource
PL_ALWAYS_INLINE const plString & GetResourceID () const
 Returns the unique ID that identifies this resource. On a file resource this might be a path. Can also be a GUID or any other scheme that uniquely identifies the resource.
 
PL_ALWAYS_INLINE plUInt64 GetResourceIDHash () const
 Returns the hash of the unique ID.
 
void SetResourceDescription (plStringView sDescription)
 The resource description allows to store an additional string that might be more descriptive during debugging, than the unique ID.
 
const plString & GetResourceDescription () const
 The resource description allows to store an additional string that might be more descriptive during debugging, than the unique ID.
 
const plString & GetResourceIdOrDescription () const
 The returns the resource description, if available, otherwise the resource ID.
 
PL_ALWAYS_INLINE plResourceState GetLoadingState () const
 Returns the current state in which this resource is in.
 
PL_ALWAYS_INLINE plUInt8 GetNumQualityLevelsDiscardable () const
 Returns the current maximum quality level that the resource could have.
 
PL_ALWAYS_INLINE plUInt8 GetNumQualityLevelsLoadable () const
 Returns how many quality levels the resource may additionally load.
 
float GetLoadingPriority (plTime now) const
 Returns the priority that is used by the resource manager to determine which resource to load next.
 
plResourcePriority GetPriority () const
 Returns the current resource priority.
 
void SetPriority (plResourcePriority priority)
 Changes the current resource priority.
 
PL_ALWAYS_INLINE const plBitflags< plResourceFlags > & GetBaseResourceFlags () const
 Returns the basic flags for the resource type. Mostly used the resource manager.
 
PL_ALWAYS_INLINE const MemoryUsage & GetMemoryUsage () const
 Returns the information about the current memory usage of the resource.
 
PL_ALWAYS_INLINE plTime GetLastAcquireTime () const
 Returns the time at which the resource was (tried to be) acquired last. If a resource is acquired using plResourceAcquireMode::PointerOnly, this does not update the last acquired time, since the resource is not acquired for full use.
 
PL_ALWAYS_INLINE plInt32 GetReferenceCount () const
 Returns the reference count of this resource.
 
PL_ALWAYS_INLINE const plTimestamp & GetLoadedFileModificationTime () const
 Returns the modification date of the file from which this resource was loaded.
 
PL_ALWAYS_INLINE plUInt32 GetCurrentResourceChangeCounter () const
 Returns the current value of the resource change counter. Can be used to detect whether the resource has changed since using it last time.
 
PL_ALWAYS_INLINE void IncResourceChangeCounter ()
 Allows to manually increase the resource change counter to signal that dependent code might need to update.
 
virtual void ResetResource ()
 If the resource has modifications from the original state, it should reset itself to that state now (or force a reload on itself).
 
void PrintHandleStackTraces ()
 Prints the stack-traces for all handles that currently reference this resource.
 
- Public Member Functions inherited from plReflectedClass
virtual const plRTTI * GetDynamicRTTI () const
 
bool IsInstanceOf (const plRTTI *pType) const
 Returns whether the type of this instance is of the given type or derived from it.
 
template<typename T >
PL_ALWAYS_INLINE bool IsInstanceOf () const
 Returns whether the type of this instance is of the given type or derived from it.
 

Private Member Functions

virtual plResourceLoadDesc UnloadData (Unload WhatToUnload) override
 Requests the resource to unload another quality level. If bFullUnload is true, the resource should unload all data, because it is going to be deleted afterwards.
 
virtual plResourceLoadDesc UpdateContent (plStreamReader *Stream) override
 Called whenever more data for the resource is available. The resource must read the stream to update it's data.
 
virtual void UpdateMemoryUsage (MemoryUsage &out_NewMemoryUsage) override
 This function must be overridden by all resource types.

Member Function Documentation

◆ GetSurfaces()

const plDynamicArray< plSurfaceResourceHandle > & plJoltMeshResource::GetSurfaces ( ) const
inline

Returns the array of default surfaces to be used with this mesh.

Note the array may contain less surfaces than the mesh does. It may also contain invalid surface handles. Use the default physics material as a fallback.

◆ UnloadData()

plResourceLoadDesc plJoltMeshResource::UnloadData ( Unload WhatToUnload)
overrideprivatevirtual

Requests the resource to unload another quality level. If bFullUnload is true, the resource should unload all data, because it is going to be deleted afterwards.

Todo
Compute memory usage

Implements plResource.

◆ UpdateContent()

plResourceLoadDesc plJoltMeshResource::UpdateContent ( plStreamReader * pStream)
overrideprivatevirtual

Called whenever more data for the resource is available. The resource must read the stream to update it's data.

pStream may be nullptr in case the resource data could not be found.

Implements plResource.

◆ UpdateMemoryUsage()

void plJoltMeshResource::UpdateMemoryUsage ( MemoryUsage & out_NewMemoryUsage)
overrideprivatevirtual

This function must be overridden by all resource types.

It has to compute the memory used by this resource. It is called by the resource manager whenever the resource's data has been loaded or unloaded.

Implements plResource.
