Tutorial Draw Vectors Lines Using Engine
#1
PHP Code:
void (*Get_Draw_Vector_Line)(const vec3_t start, const vec3_t end, const vec3_t Minsint noIdea  ) = (void (__cdecl *)(const vec3_t , const vec3_t , const vec3_t int     ))0x402A50

PHP Code:
void (*Set_Draw_Vector_Line)(const vec3_t start, const vec3_t Mins, const vec3_t Maxsint noIdea, const vec3_t VecTorSizeint Unknow2int unknow3  ) = (void (__cdecl *)( const vec3_t , const vec3_t , const vec3_t int , const vec3_t int int   ))0x6B19F0

exemplar how to use

PHP Code:
TraceSettings->Mask get_bullet_penetration_table)->Mask;
        
                
vec3_t Start;
                
vec3_t Maxs;
                
                
Get_Draw_Vector_LineStartEndvec3_origin0  );
                
Set_Draw_Vector_LineStartvec3_originMaxs0vec3_origin00   );
                
Set_Draw_Vector_LineEndvec3_originMaxs0vec3_origin00   );
                
                
Set_Weapon_CL_Trace(CTraceStartvec3_originMaxsEndcent->ClientNum0x800000 1024TraceSettings ); 

but also check the isVisible Code

corrected

PHP Code:
void (*Draw2D_Debug_Line)(const vec3_t start, const vec3_t end,  vec4_t Colorbool dontDrawTruhWalls  ) = (void (__cdecl *)(const vec3_t  , const vec3_t ,  vec4_t bool ))0x402A50;
void (*Draw3D_Debug_Line)(const vec3_t start, const vec3_t BoxSize,   const vec3_t VecTorSize int noIdea,  vec4_t colorbool  dontDrawTruhWallsint PredictEffect  ) = (void (__cdecl *)( const  vec3_t , const vec3_t ,  const vec3_t int ,  vec4_t bool int    ))0x6B19F0

Just made 3D box as well
