 |
|
| When calling TA::CollisionObjectCachedPolyData::GetNewPolygon in CachedLocalPolygons it returns Polygon object whos fields are uninitialized and subsequent call to Polygon::GetVertex result in assertion. Am i doing something wrong? |

This funciton is used internally in TrueAxis in a couple of places for complex collision meshes. This means the function should work.
Ok, actually, there is a bug in the function where the number of vericies is not set, causing the assert.
to work around, in the file "CollisionObjectCachedPolyData.h", you change the struct:
| Code: | struct Polygon
{
const Vec3& GetNormal();
void SetNormal(const Vec3& v3Normal);
int GetAttribute() const;
void SetAttribute(int nAttribute);
int GetNumVertices() const;
void SetCollisionID(u32 nCollisionID);
u32 GetCollisionID() const;
Vertex& GetVertex(int nIndex);
const Vertex& GetVertex(int nIndex) const;
void GenerateEdgeNormals();
#ifndef lOllOllOOlO
private:
#endif
Vec3 lOOOlOOOOO;
int llOlllOlOOO;
int lOllOlllOl;
u32 llOlllOlllO;
u32 lllOlOOlOOO;
Vertex llOllllOlO[lOlllOOlOll];
}; |
by adding the fuction:
| Code: | | void SetNumVertices(int nVertices) { lOllOlllOl = nVertices; } |
inside the body of the class.
Then you must set the number of vertices to the same number give ot the function GetNewPolygon |

| one more question. it turns out that TA::CollisionObjectCachedPolyData can allocate 64 polygons max, is there any way to increase it? thanks in advance |
