Constructor & Destructor Documentation

◆ HitRecord() [1/3]

HitRecord ( )
inline

Default Constructor.

Initializes all members to NULL.

5920 : nodeRef(NULL) { next = NULL; modContext = NULL; distance = 0; hitInfo = 0; hitData = NULL;}
#define NULL
Definition: autoptr.h:18
HitData * hitData
In case 4 bytes in hitInfo is not enough space to identity the sub-object element,...
Definition: object.h:5918
INode * nodeRef
Points to the node that was hit.
Definition: object.h:5904
ModContext * modContext
Points to the ModContext of the modifier.
Definition: object.h:5906
DWORD distance
The 'distance' of the hit. An implementation defined value that is lower for hits that are closer.
Definition: object.h:5908
ulong hitInfo
A general unsigned long value.
Definition: object.h:5912

◆ HitRecord() [2/3]

HitRecord ( INode nr,
ModContext mc,
DWORD  d,
ulong  inf,
HitData hitdat 
)
inline

Constructor.

The data members are initialized to the data passed.

5922  {
5923  next = NULL;
5924  nodeRef = nr; modContext = mc; distance = d; hitInfo = inf; hitData = hitdat;
5925  }

◆ HitRecord() [3/3]

HitRecord ( HitRecord n,
INode nr,
ModContext mc,
DWORD  d,
ulong  inf,
HitData hitdat 
)
inline

Constructor.

The data members are initialized to the data passed.

5927  {
5928  next = n;
5929  nodeRef = nr; modContext = mc; distance = d; hitInfo = inf; hitData = hitdat;
5930  }

◆ ~HitRecord()

Destructor.

If HitData has been allocated, it is deleted as well.

Member Function Documentation

◆ Next()

HitRecord* Next ( )
inline

Each HitRecord maintains a pointer to another HitRecord.

This method returns the next hit record.

5933 { return next; }

Member Data Documentation

◆ nodeRef

INode* nodeRef

Points to the node that was hit.

◆ modContext

ModContext* modContext

Points to the ModContext of the modifier.

◆ distance

DWORD distance

The 'distance' of the hit. An implementation defined value that is lower for hits that are closer.

◆ hitInfo

ulong hitInfo

A general unsigned long value.

Most modifiers will just need this to identity the sub-object element. The edit mesh modifier uses the value to store the index of the vertex or face that was hit for example.

◆ hitData

HitData* hitData

In case 4 bytes in hitInfo is not enough space to identity the sub-object element, this pointer is available.

To use this, a developer would define a class derived from HitData that would contain the necessary data. The HitData class has one member function, a virtual destructor, so the derived class can be properly deleted when the HitRecord instance is deleted by the system.
