Draw Vectors Lines Using Engine - d0h! - 01-31-2011

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;

Just made 3D box as well

edit:

easy reverence to find it in any cod

PHP Code:
bool __cdecl sub_7FCA20() { return (dword_33F0E34 || (dword_33F0E2C = 2048, dword_33F0E4C = 4096, dword_33F0E3C = 4096, sub_711FD0((int)&dword_33F0E34, 0x16000u, (int)"Client Debug Lines"), sub_711FD0((int)&dword_33F0E38, 0x2000u, (int)"Client Debug Lines"), dword_33F0E30 = 0, sub_711FD0((int)&dword_33F0E54, 0x2C000u, (int)"Client Debug Lines"), sub_711FD0((int)&dword_33F0E58, 0x4000u, (int)"Client Debug Lines"), dword_33F0E50 = 0, sub_711FD0((int)&dword_33F0E44, 0x2C000u, (int)"Client Debug Lines"), dword_33F0E40 = 0, dword_33F0E34)) && dword_33F0E38 && dword_33F0E54 && dword_33F0E58 && dword_33F0E44; }

Client Debug Lines calls in the functions above
