General Question simple vc help

gattispilot · Apr 5, 2017

Ok. This is got me confused.

A simple VC. 3 mesh groups (2mfds and 1 hud)

But for some reason the left mfd is drawn on the hud screen also.

tells which mesh group to assign for hud and mfd

Code:

mfds_left.ngroup = 0;
	mfds_right.ngroup = 2;

	huds.ngroup = 1;
	huds.size = 0.25;

tells the mesh #1 is the VC mesh

Code:

	SetMeshVisibilityMode(AddMesh(cmMesh, &ofs), MESHVIS_EXTERNAL | MESHVIS_VC); //mesh number 0
	SetMeshVisibilityMode(AddMesh(vcMesh, &ofs), MESHVIS_EXTERNAL | MESHVIS_VC); //mesh number 1




	mfds_left.nmesh = 1;
	mfds_right.nmesh = 1;


		huds.nmesh = 1;
	huds.hudcnt = ofs_hud;

turn on vc

Code:

bool TALON::clbkLoadVC(int id)
	{
		SetCameraDefaultDirection(_V(0, -0.25, 0.97)); // forward

		oapiVCRegisterHUD(&huds);
		oapiVCRegisterMFD(MFD_LEFT, &mfds_left);
		oapiVCRegisterMFD(MFD_RIGHT, &mfds_right);
		//	oapiVCRegisterMFD (MFD_LEFT, &mfds_co);  // was commented
		return true;
	}

Which groups did you assign?

HERE. Left Mfd is assigned group 0
right mfd is assigned group 2

and hud group 1

Only 3 groups in the VC mesh

GLS · Apr 5, 2017

Are you using the same texture on all 3 groups? (I don't think you need any in those groups)

Yes. It is the same as the Orion MPCV It is just a blank texture with a x on it.

All three are drawn. But the left mfd is also drawn on the HUd group

Thanks

Try TEXTURE 0 in the mesh.

gattispilot · Apr 5, 2017

Ok. So no texture? I can do that

Urwumpe · Apr 5, 2017

Some sort of a step between. No texture, but texture coordinates. For that you traditionally need to texture a group and then delete the texture line in the mesh.

gattispilot · Apr 5, 2017

Oh. Ok I will try it.
Thanks

Not sure what happens when groups don't have the TEXTURE and MATERIAL entries... anyway, I think the MFDs need to have a material with the last line at "1 1 1 1", or they won't be visible.

gattispilot · Apr 6, 2017

Well I did this:

Code:

0.878431 0.878431 0.878431 1.000000

0.800000 0.800000 0.800000 1.000000

I can see them. But the Left mfd is drawn on the center mesh group also

Well it is drawn correctly except the HUd is too bright?

GLS · Apr 6, 2017

You need a different material for the HUD then.

gattispilot · Apr 24, 2017

Well I got it work. Thanks

Now I am trying to get 3 working MFDs and a hud. I am using the code for the Endurance. But keep getting ctd when going to VC.

But I remember a guide to set but working buttons on mfd but can't seem to find it now

Small hint: A good way to prevent CTDs in C++ is to make sure you know which variable exists when and when the memory location of this variable is used for something else.

Variable scopes is a common problem in C and C++ because of the pointers. Sometimes its no problem, because you just do a call by reference. Sometimes it fails, because the called Orbiter API stored the pointer to the object and expects you to keep this object in memory until ovcExit.

That is for the new Panel2D interface ... with a "PanelMaker" class, this interface could be much more useful for developers I think, right now its a bit too low-level for easy changes.

I think he means the example about how to define a third MFD in Orbiter with custom buttons.

gattispilot · Apr 24, 2017

No but that might help. This was on the Hangar. I remember I got the buttons to work but not labels

How are you doing the labels?
