Question C++ to Lua conversion

[johnnymanly]

I'm just learning Lua and I tried to convert this C++ code

int i;
        
        for (i = 0; i < 6; i++) {
            oapiVCRegisterArea (MFD1_LBUTTON1+i, PANEL_REDRAW_NEVER, PANEL_MOUSE_LBDOWN);
            oapiVCSetAreaClickmode_Spherical(MFD1_LBUTTON1+i, _V(-0.31, 0.0547 - (i * 0.0245), 0.649), 0.0123);
            
            oapiVCRegisterArea (MFD1_RBUTTON1+i, PANEL_REDRAW_NEVER, PANEL_MOUSE_LBDOWN);
            oapiVCSetAreaClickmode_Spherical(MFD1_RBUTTON1+i, _V(-0.107, 0.0547-(i * 0.0245), 0.649), 0.0123);
        }

All I could come up with is

local i

  for i=0, i<6, i=i+1 do
    oapi.VC_register_area (MFD1_LBUTTON1+i, PANEL_REDRAW_NEVER, PANEL_MOUSE_LBDOWN)
    oapi.VC_set_areaclickmode_spherical(MFD1_LBUTTON1+i, _V(-0.31, 0.0547 - (i * 0.0245), 0.649), 0.0123)

    oapi.VC_register_area (MFD1_RBUTTON1+i, PANEL_REDRAW_NEVER, PANEL_MOUSE_LBDOWN)
    oapi.VC_set_areaclickmode_spherical(MFD1_RBUTTON1+i, _V(-0.107, 0.0547-(i * 0.0245), 0.649), 0.0123)
  end

which is incorrect.
Can anyone point me in the right direction?

It should be

for i=0,5 do
  ...
end

Thanks Gondos, that's it.

Thanks Gondos, that's it.

No problem, also if you haven't noticed it yet, the constants are not defined in the same way so you need to adjust you code for it :
PANEL_REDRAW_NEVER -> PANEL_REDRAW.NEVER
PANEL_MOUSE_LBDOWN -> PANEL_MOUSE.LBDOWN

Yes, I saw them once I got going.
Thanks again for having a look and all your work on Lua for Orbiter.
