Implementing two default MFDs in VC on Lua

[johnnymanly]

Yes. This is the code I used. It is based on the Atlantis source code. I called everything directly from clbk_VCredrawevent() though I should have made a separate function.

local left_selection = {
    [AID_MFD1_LBUTTONS] = true,
    [AID_MFD1_RBUTTONS] = true
  }

  if left_selection[id] then
    local bt, side
    local mfd = id - AID_MFD1_LBUTTONS and MFDID.LEFT
    side = (id == AID_MFD1_LBUTTONS and 0 or 1)
    local skp = oapi.get_sketchpad(surf)
    skp:set_font(gfont)
    skp:set_textcolor(_RGB(97,160,80))
    skp:set_textalign(SKP.CENTER, SKP.BASELINE)
    skp:set_backgroundmode(SKP.TRANSPARENT)

  local y = 24

  for bt = 0,5 do
    local label = oapi.mfd_buttonlabel(MFDID.LEFT, bt + side * 6)
    if label then
      skp:text(15, y, label, #label)
    end
    y = y + 36.5
  end
  oapi.release_sketchpad(skp)
  return true
  end

Thanks. Could you tell me which add-on you used this in? Is it released? I just wanted to try it out.

 

[johnnymanly]

It's not released. It's not finished.

Thanks! It looks like just what I need. I'll try to understand the code you showed above and let you know if I don't understand something.

 

[johnnymanly]

That code is a bit sketchy so read it along side "orbiter_lua.chm" and you'll get the idea.

Did you apply the tex to the buttons?

Did you apply the tex to the buttons?

If it's to me, then not yet. I just only started learning this subject.

 

[gattispilot]

Oh I can help with your mfd

Thanks. I'm experimenting with Sketchpad for the first time. I created test mesh that contains two squares. I'm trying to draw dynamic labels for MFD side buttons. For now I'm noticing an interesting thing I don't understand, namely the upper left corner of the left square is slanted:



Red rectangles are areas defined here:

local tex1 = oapi.get_texturehandle(testMESH, 1)
oapi.VC_register_area(AID_CDR1_BUTTONS, _R(0,1,255,14), PANEL_REDRAW.USER, bit.bor(PANEL_MOUSE.LBDOWN, PANEL_MOUSE.LBUP, PANEL_MOUSE.LBPRESSED, PANEL_MOUSE.ONREPLAY), PANEL_MAP.BACKGROUND, tex1)
oapi.VC_register_area(AID_CDR2_BUTTONS, _R(0,15,255,28), PANEL_REDRAW.USER, bit.bor(PANEL_MOUSE.LBDOWN, PANEL_MOUSE.LBUP, PANEL_MOUSE.LBPRESSED, PANEL_MOUSE.ONREPLAY), PANEL_MAP.BACKGROUND, tex1)

Sorry, it looks it was cut off by the windshield. I reduced the squares and now everything seems to be good:

I can't believe it works :

Button labels dissapear when zoom out:



Draw distance depends on the texture that is used for the button labels. For a 256x256 texture the button labels don't disappear, but the labels are quite pixelated. On the screenshots the texture of resolutoin 512x512 is used.

Any suggestion are welcome.

 

[johnnymanly]

I don't know why that's happening but you could try a "bare minimum" texture.
this one is 64 X 256 for all the MFD buttons.

 

[misha.physics]

Well, I did it:



White labels look more contrasting. Thank you all for help!
