For my external radar i totally reversed the fullmap radar, so im sharing it because
it might be usefull for some of you.

CRadarVecs * GetRadarInfo(CRadarHud * radarhud, CRadarSize radarSize)
{	
	float v15, v19;
	CRadarVecs * radarvecs;

	float v14 = radarhud->w / radarhud->h;
	float v25 = *(float *)(0x8FF100 + (DWORD)487708) / *(float *)(0x8FF100 + (DWORD)487712);
	float v22 = radarSize.VecA + radarhud->x;
	float v23 = radarSize.Vecb + radarhud->y;

	float v13 = v25;
	float v12 = v14;

	if ( v14 >= v25 )
        {    
		float v27 = (v13 / v12) * radarhud->w;
		float v17 = (radarhud->w * 0.5) + v22;

		radarvecs->w = v17 - (0.5 * v27);
		radarvecs->h = v23;
		radarvecs->x = v27;
		v15 = radarhud->h;		
        }
        else
        {
		float v16 = (radarhud->h * 0.5) + v23;
		float v26 = (v12 / v13) * radarhud->h;

		radarvecs->w = v22;		
		radarvecs->h = v16 - (0.5 * v26);
		radarvecs->x = radarhud->w;
		v15 = v26;
        }

	radarvecs->y = v15;
	float v28 = *(float *)(*(DWORD*)(0x8F16D0) + 0xC);
	float v18 = radarvecs->x * 0.25;

        if ( v28 <= v18 )
        {
		v19 = v28;
        }
        else
        {
		v19 = v18;
        }

        float v20 = 0.25 * radarvecs->y;
        if ( v20 < v19 )
        {		
		v19 = v20;
        }

	radarvecs->w = radarvecs->w + v19;
	radarvecs->h = radarvecs->h + v19;

	float v21 = v19 + v19;

	radarvecs->x = radarvecs->x - v21;
	radarvecs->y = radarvecs->y - v21;

	return radarvecs;
}

float * GetRadarPos(CRadarVecs * radarvecs, Vec3 vTarget)
{
	Vec3 vOrigin;
	float pos[2];

        vOrigin[0] = vTarget[0] - *(float *)(0x8FF100 + (DWORD)487700);
        vOrigin[1] = vTarget[1] - *(float *)(0x8FF100 + (DWORD)487704);
    
        float v18 = (*(float *)(0x8FF100 + (DWORD)487692) * vOrigin[0]) - (*(float *)(0x8FF100 + (DWORD)487688) * vOrigin[1]);
        float v19 = (vOrigin[1] * -*(float *)(0x8FF100 + (DWORD)487692)) - (vOrigin[0] * *(float *)(0x8FF100 + (DWORD)487688));
    
	float v20 = (v18 / *(float *)(0x8FF100 + (DWORD)487708)) - 0.5;
        float v21 = (v19 / *(float *)(0x8FF100 + (DWORD)487712)) - 0.5;
  
	pos[0] = radarvecs->x * v20;	
	pos[1] = radarvecs->y * v21;	

	return pos;
}

void ShowRadarPos(CRadarHud * radarhud, CRadarSize radarSize, Vec3 vTarget, int Shader)
{
	float * fPos;
	CRadarVecs * radarvecs = GetRadarInfo(radarhud, radarSize);

	fPos = GetRadarPos(radarvecs, vTarget);	
    
	float v20 = radarhud->x + (radarhud->w * 0.5f) + fPos[0];
	float v10 = radarhud->y + (radarhud->h * 0.5f) + fPos[1];

	DrawPic(v20, v10, 20, 20, cWhite, Shader);
}

example code on how to use it

DrawStretchPic(radarhud.x, radarhud.y, radarhud.w, radarhud.h, 0.0f, 0.0f, 1.0f, 1.0f, cWhite, *(DWORD*)0x976210);
	
for(int i=0; i<1024; i++)
{
	CEntity * pEnt = GetEntityByIndex(i);
	if(!(pEnt->isAlive & 1))
		continue;

	if(pEnt->eType == ET_MISSILE)
	{
		char * szShader = GetWeaponShader(pEnt->WeaponNum);
		if(szShader)
			ShowRadarPos(&radarhud, radarsize, pEnt->vOrigin, RegisterShader(szShader, 7));
	}
}

seems nice !

Don't post if you don't understand what to do with the code.

I hate being new to C++ xD

Still have to learn a crap tonne before I could do something like this. Would be a lot easier if one of the more experienced hackers created a video tutorial.

Oh well, goodjob ;D
