Draw circle on ground

[Metin2 Dev 12260]

Currently im trying to draw a circle with my player as center point and if he moves, the circle should also move with him. But my problem is, that I dont know how to do it. So far this is the code:

void CPythonCharacterManager::DrawCircle()
{
	CInstanceBase* pMainInstance = CPythonPlayer::Instance().NEW_GetMainActorPtr();
	if (!pMainInstance)
		return;

	TPixelPosition pixelPos;
	pMainInstance->NEW_GetPixelPosition(&pixelPos);

	static CScreen screen;
	STATEMANAGER.SetRenderState(D3DRS_TEXTUREFACTOR, D3DCOLOR_XRGB(50, 50, 255));

	const int iSteps = 60;
  	const float fRadius = 200;
	screen.RenderCircle2d(pixelPos.x, pixelPos.y, pixelPos.z, fRadius, iSteps);
}

When I call the code, nothing happens. Tried also with other D3DRender state type, but either strange visual bugs appear or nothing happens

You must use screen position, not the position of the instance. Since the main instance is located always at the center of the screen you can use:

RenderCircle2d(0, 0, 0, 200);

I changed the code like that 

void CPythonCharacterManager::DrawCircle()
{
	CInstanceBase* pMainInstance = CPythonPlayer::Instance().NEW_GetMainActorPtr();
	if (!pMainInstance)
		return;

	static CScreen screen;
  	STATEMANAGER.SetRenderState(D3DRS_TEXTUREFACTOR, D3DCOLOR_XRGB(50, 50, 255));
  
	screen.RenderCircle2d(0.0f, 0.0f, 0.0f, 100.0f);
}

But still same problem, when I call the function nothing happens. I debuged it already and set a breakpoint at the function and he call it fully.

//STATEMANAGER.SaveRenderState(D3DRS_ZENABLE, FALSE); // This would make the circle render on top of everything.
STATEMANAGER.SetRenderState(D3DRS_FOGENABLE, FALSE);
STATEMANAGER.SetRenderState(D3DRS_LIGHTING, FALSE);

static CScreen s_kScreen;
s_kScreen.SetDiffuseColor(0.0f, 1.0f, 1.0f);
s_kScreen.RenderCircle2d(0, 0, 0, 300, 50);

//STATEMANAGER.RestoreRenderState(D3DRS_ZENABLE);
STATEMANAGER.SetRenderState(D3DRS_FOGENABLE, TRUE);
STATEMANAGER.SetRenderState(D3DRS_LIGHTING, TRUE);

Still same problem

Thank you very much, now it works well.

One question more. Is it easy to edit the code, so the circle follow the terrain height or depth?
