CoD2 D3DBSP

Tech: LuaJIT + FFI for C-structs

Toujane example


Movement:

WASD for Position
Arrow Keys for Camera
Q/E for Camera Down/Up (like in CoD2)

		typedef struct
{
    float position[3];
    float normal[3];
    int bla[11];
} aDrawVert;

typedef struct
{
    int length;
    int offset;
} aLump;

typedef struct
{
    char ident[4];
    int version;
    aLump lumps[100];
} aHeader;

typedef struct
{
    short index[3];
} aTriangle; // depricated

typedef struct
{
    unsigned short offset;
    //unsigned short b;
    //unsigned short c;
} aDrawIndex;

/*typedef struct
{
    unsigned short a;
    unsigned short b;
    unsigned short c;
} aDrawIndex;*/


// is empty in mp_analyse1
typedef struct
{
    float position[3];
} aCollisionVert;

typedef struct
{
    int planeIndex;
    int children[2];
    int mins[3];
    int maxs[3];
} aNode;

typedef struct
{
    //int cluster; // ???
    //int area; // ???

    //int maxs[3]; // ???

    //int faceCount;
    //int brushFirst;
    //int brushCount;
    int someA[4];
    int firstLeafBrush; // lookup in leafbrushes
    int numLeafBrushes;
    int someB[3];
} aLeaf;

typedef struct

    unsigned short bla;
    unsigned short foo;
    unsigned int vertexFirst;
    unsigned short nVertex;

    unsigned short nTriangles;
    unsigned int triangleFirst;
} aTriangleSoup; 
	

Draw all triangle faces:

		
function bspdraw()

    colors = {
        {0, 0, 0},
        {0, 0, 1},
        {0, 1, 0},
        {0, 1, 1},
        {1, 0, 0},
        {1, 0, 1},
        {1, 1, 0},
        {1, 1, 1}
    }

    for i = 0,nTriangleSoups-1 do
        soup = triangleSoups + i
        
        gl.glBegin(gl.GL_TRIANGLES)
        for nTriangles = 0, soup.nTriangles-1 do
            drawIndex = drawIndexes + (soup.triangleFirst + nTriangles)
            
            co = colors[(nTriangles%8) + 1]
            gl.glColor3f(co[1], co[2], co[3])
            
            a  = vertices + (drawIndex.offset + soup.vertexFirst)
            gl.glVertex3fv(a.position)
        end
        gl.glEnd()
    end
end 
	

Serthy, could you post your full solution of how to use your structs? That would help alot
