Meshing Question Basic mesh crashes :(

[innovine]

I've just started working with the SDK and meshes. I've got ShuttlePB.dll compiled and running. If I use the shuttlePB.dll it works ok. But as soon as I switch the mesh to my own custom mesh (a sphere with a material) then Orbiter crashes after loading. Below is the mesh I am using (exported from anim8or using urwumpes exporter):

Nevermind, I seem to have fixed it. I deleted all the aerodynamics code and the problem went away. Perhaps thre is code which references an animation or a control surface or something not found in my mesh.

Perhaps thre is code which references an animation or a control surface or something not found in my mesh.

There are animations of 2nd and 3rd mesh groups, which don't exist in your mesh:

static UINT [highlight]GRP_LWING = 2[/highlight];
static UINT [highlight]GRP_RWING = 3[/highlight];

{...}

MGROUP_ROTATE ShuttlePB::[highlight]trans_Laileron[/highlight] (0, &[highlight]GRP_LWING[/highlight], 1, LWING_REF, LWING_AXIS, AILERON_RANGE);
MGROUP_ROTATE ShuttlePB::[highlight]trans_Raileron[/highlight] (0, &[highlight]GRP_RWING[/highlight], 1, RWING_REF, RWING_AXIS, AILERON_RANGE);
MGROUP_ROTATE ShuttlePB::[highlight]trans_Lelevator[/highlight] (0, &[highlight]GRP_LWING[/highlight], 1, LWING_REF, LWING_AXIS, -ELEVATOR_RANGE);
MGROUP_ROTATE ShuttlePB::[highlight]trans_Relevator[/highlight] (0, &[highlight]GRP_RWING[/highlight], 1, RWING_REF, RWING_AXIS, ELEVATOR_RANGE);

{...}

AddAnimationComponent ([highlight]anim_Laileron[/highlight], 0, 1, &[highlight]trans_Laileron[/highlight]);
AddAnimationComponent ([highlight]anim_Raileron[/highlight], 0, 1, &[highlight]trans_Raileron[/highlight]);
AddAnimationComponent ([highlight]anim_elevator[/highlight], 0, 1, &[highlight]trans_Lelevator[/highlight]);
AddAnimationComponent ([highlight]anim_elevator[/highlight], 0, 1, &[highlight]trans_Relevator[/highlight]);

They are referenced by control surfaces:

// aerodynamic control surface defintions
CreateControlSurface (AIRCTRL_ELEVATOR, 1.5, 0.7, _V( 0,0,-2.5), AIRCTRL_AXIS_XPOS, [highlight]anim_elevator[/highlight]);
CreateControlSurface (AIRCTRL_AILERON, 1.5, 0.25, _V( 1,0,-2.5), AIRCTRL_AXIS_XPOS, [highlight]anim_Laileron[/highlight]);
CreateControlSurface (AIRCTRL_AILERON, 1.5, 0.25, _V(-1,0,-2.5), AIRCTRL_AXIS_XNEG, [highlight]anim_Raileron[/highlight]);

You don't need to delete all the aerodynamics code. You can just not define those animations, and call CreateControlSurface without animation index (or with -1 index).

Thanks for pointing that out!

It is not at all obvious from looking through the code that the 2 and 3 refer to mesh groups, they just look like magic numbers. A comment above it would probably help. In this case, deleting the code is fine as I am not intending to enter any atmospheres if I can help it !
