C++ Question Drawing MFD button labels in a 3D cockpit

[Mr Martian]

Hi All,

Firstly, I hope you have all been safe and well during these times, I've busy and away from the Orbiter community for a long while now.

I am working on an new project, and am trying to figure out a problem I have always struggled with; drawing the labels on MFD buttons in a VC. I am currently just working on a very simple ShuttlePB testbed vessel (to overcome this) so what I have in clbkLoadVC is minimal, and adapted from the ShuttleA source code:

bool ShuttlePB::clbkLoadVC (int id) { static VCMFDSPEC mfds_left = {1, 1}; SetCameraDefaultDirection (_V(0,0,1)); // forward switch (id) { case 0: // pilot SetCameraOffset (_V(0,0.3638965,1.717594)); SetCameraShiftRange (_V(0,0,0.1), _V(-0.2,0,0), _V(0.2,0,0)); oapiVCRegisterMFD (MFD_LEFT, &mfds_left); SURFHANDLE tex1 = oapiGetTextureHandle (mh_vc,1); //engine thrust tex // MFD1 buttons tex1 = oapiGetTextureHandle (mh_vc,1); //mfd buttons tex oapiVCRegisterArea (AID_MFD1_LBUTTONS, _R( 8 ,9, 32,218), PANEL_REDRAW_MOUSE|PANEL_REDRAW_USER,PANEL_MOUSE_LBDOWN|PANEL_MOUSE_LBUP|PANEL_MOUSE_LBPRESSED|PANEL_MOUSE_ONREPLAY, PANEL_MAP_BACKGROUND, tex1); oapiVCSetAreaClickmode_Quadrilateral(AID_MFD1_LBUTTONS, _V(-0.2762892, -8.237985E-02, -2.788238E-02+2.7), _V(-0.3193802, -8.237985E-02, -2.788238E-02+2.7), _V(-0.2762892, -0.122936, -2.788238E-02+2.7), _V(-0.3193802, -0.122936, -2.788238E-02+2.7)); break; } return true; }

Again, it is extremely simple, as I just want to overcome and understand this issue (anyone who played with my earlier ISV Pegasus addon may remember the lack of MFD button labels).

I thought it may have something to do with flagging the meshgroup as D (dynamic), but alas this seems to make no difference.

If anyone could offer any advice I would greatly appreciate it.

Thank you in advance,

MrMartian

So what happens? I have done them. BUt willing to help

Hi Gattispilot, Thanks for your reply!

So just nothing is displayed, the buttons work, but there are no visible labels.



The above image shows what I have. I just placed a group over one of the buttons (circled in red). This group I have set the geometry for the entire left button array to fit into this small box (silly I know, but just wanted to see if any buttons appear). It is a square shape with a texture that fits perfectly into said shape, if this makes sense. I would have expected to see very small labels in this box, but instead nothing. Do you think it may have something to do with my texture positioning?

Thank you again.

Not sure if this will help, do you know of this?

Developer masterclass: Creating 2-D panels the new way

Orbiter 2010 introduces a new way to define 2-D panels. Documentation for this is still thin on the ground (but under development), and currently only the stock DG provides an example for it. I thought that maybe a small tutorial series may be the way to nudge developers towards adopting the...

Its quite old, so I'm not sure if its still relevant.

Hi both,

Thank you for your replies. Notebook thank you for the link that was worth a read. Realised I never loaded any fonts... Feel a bit stupid

I have button text working now, but one issue I can't seem to work around, is whenever I check any of the left mfd buttons, the labels for the right buttons dissapear, and don't reappear until I click on some of the right buttons. Anyone have any ideas as to what may be causing this? I thought it may have something to do with clbkVCRedrawEvent, but I'm really scratching my head here.

In clbkLoadVC it doesn't matter if I register the area for the left buttons or right buttons first, it will always be the right buttons that present this issue, left buttons work perfectly...

Many thanks in advance.

Actually, I think I may have sorted it.

In clbkLoadVC, in the line where the area to print buttons on is registered, I have changed the line (below) to PANEL_REDRAW_ALWAYS. this line was just taken from Martins' ShuttleA source code, and was previously PANEL_REDRAW_USER.

oapiVCRegisterArea (AID_MFD1_RBUTTONS, _R( 30 ,100, 512,512), PANEL_REDRAW_MOUSE|[COLOR=rgb(250, 197, 28)]PANEL_REDRAW_ALWAYS[/COLOR],PANEL_MOUSE_LBDOWN|PANEL_MOUSE_LBUP|PANEL_MOUSE_LBPRESSED|PANEL_MOUSE_ONREPLAY, PANEL_MAP_BACKGROUND, tex1);

This works for now, and I don't see any issue that may arise from this, however if anyone knows a reason why it should be PANEL_REDRAW_USER I would be interested to understand this.

Thank you all!
