I'm trying to make a simple radar for a HL2MP mod.
I'm trying to get an idea of what vars are being passed around by using the Msg() function. However, when I call it on int drawX & Y I get the value of 0.000. Is there something wrong with my code that could be doing this?
if(pOtherPlayer == C_BasePlayer::GetLocalPlayer( ))
continue; // Don't draw self
Vector offset = pOtherPlayer->GetAbsOrigin() - pLocalPlayer->GetAbsOrigin();
offset /= scale;
offset.x += panelWidth/2;
offset.y += panelHeight/2;
//int drawX = offset.x + panelWidth/2;
//int drawY = offset.x + panelHeight/2;
const Vector fixed = Vector(offset.x,offset.y,0);
QAngle angles;
VectorAngles(fixed, angles);
angles.y += pLocalPlayer->EyeAngles().y; // not sure whether you want to add to x, y or z here
const QAngle angleRef = angles;
Vector rotated;
AngleVectors(angleRef, &rotated);
int drawX = rotated.x;
int drawY = rotated.y;
Msg("DrawX = %f \nDrawY = %f", drawX, drawY);
if ( drawX > 0 && drawY > 0
&& drawX < panelWidth && drawY < panelHeight )
{// this clips to a square, which is less pretty but easier
surface()->DrawFilledRect( drawX-1, drawY-1, drawX+1, drawY+1 );
Msg( "surface()->DrawFilledRect( drawX-1 %f, drawY-1 %f, drawX+1 %f, drawY+1 %f );",
drawX-1, drawY-1, drawX+1, drawY+1 );
}
} // end for loop
}
void CRadarHud::togglePrint()
{
if (!show_radar.GetBool())
this->SetVisible(false);
else
this->SetVisible(true);
}
void CRadarHud::OnThink()
{
togglePrint();
BaseClass::OnThink();
}
Thanks for your help
This is the kind of situation where the debugger will be your best friend. You should start at the beginning of your paint method and follow the variables' values line-by-line. More than likely, you are either using an uninitialized variable or perhaps one of your functions is returning the wrong variable.
Also, since drawX and drawY are integers, your Msg call should use %i instead of %f:
I don't think this would give you the error you are getting, though.
