[Tutorial] Draw Vectors Lines Using Engine

[d0h!]

PHP Code:

void (*Get_Draw_Vector_Line)(const vec3_t start, const vec3_t end, const vec3_t Mins, int 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 Maxs, int noIdea, const vec3_t VecTorSize, int Unknow2, int 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( 0 )->Mask;
        
                vec3_t Start;
                vec3_t Maxs;
                
                Get_Draw_Vector_Line( Start, End, vec3_origin, 0  );
                Set_Draw_Vector_Line( Start, vec3_origin, Maxs, 0, vec3_origin, 0, 0   );
                Set_Draw_Vector_Line( End, vec3_origin, Maxs, 0, vec3_origin, 0, 0   );
                
                Set_Weapon_CL_Trace(CTrace, Start, vec3_origin, Maxs, End, cent->ClientNum, 0x800000 + 1024, TraceSettings ); 


but also check the isVisible Code

corrected

PHP Code:

void (*Draw2D_Debug_Line)(const vec3_t start, const vec3_t end,  vec4_t Color, bool 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 color, bool  dontDrawTruhWalls, int PredictEffect  ) = (void (__cdecl *)( const  vec3_t , const vec3_t ,  const vec3_t , int ,  vec4_t , bool , int    ))0x6B19F0;
