SDK Question Animation not animating

[Hlynkacg]

Ok I need some more help.

I followed the all the steps in the API_Guide but my Animation is not animating.

Here's the animation component as curently defined, the "DefineAnimations" function is called in the constructor as per the pdf.

void Spider::DefineAnimations (void)
{
	// EVA Hatch
	static UINT HatchGroups[2] = {8};	// participating groups // {EvaHatch}
	static MGROUP_ROTATE Hatch (
		mesh_AS,						// mesh index
		HatchGroups, 2,					// group list and # of groups 
		_V(-0.394,-0.578, 1.661),		// rotation reference point 
		_V( 0, 1, 0),				// rotation axis 
		0.5*PI				// angular rotation range (pi/2 aka 90 DEG)
		);
	
	anim_Hatch = CreateAnimation(0);
	AddAnimationComponent ( anim_Hatch, 0, 1, &Hatch);
}

then in ClbkPost step I have the following which I adapted from the stock DG...

	// animate hatch *Copied from stock DG*
	if (HatchStatus > CLOSED) 
	{
		double da = simdt * HATCH_OPERATING_SPEED;
		if (HatchStatus == CLOSING) 
		{
			if (hatch_proc > 0.0) hatch_proc = max (0.0, hatch_proc - da);
			else HatchStatus = CLOSED;
		}
		else 
		{
			if (hatch_proc < 1.0) hatch_proc = min (1.0, hatch_proc + da);
			else HatchStatus = OPEN;
		}
		
		LEM::SetAnimation( anim_Hatch, hatch_proc);
	}
	sprintf(oapiDebugString(),"hatch_proc %f Hatch Status %i", hatch_proc, HatchStatus);

finally I have this simple function in clbkConsumebufferedkey

	// Open Hatch when [K] is pressed.
	if(key == OAPI_KEY_K  && down && !KEYMOD_SHIFT(kstate) && !KEYMOD_CONTROL (kstate) && !KEYMOD_ALT(kstate))
	{
		if (HatchStatus != OPEN) HatchStatus = OPENING;
		else if (HatchStatus != CLOSED) HatchStatus = CLOSING;
		return 1;
	}

now I've been able to confirm via my oapiDebugString that "hatch_proc" and the "HatchStatus" enumerator are both working properly. The question therefore is why isn't the hatch moving?

is it an issue with the "SetAnimation" function or the definition itself.

Ok I have it working and have highlighted the things I've changed...

	// EVA Hatch
	static UINT HatchGroups = 8;	// participating groups // {EvaHatch}
	static MGROUP_ROTATE Hatch (
		[COLOR="red"]3,[/COLOR]								// mesh index
		[COLOR="red"]&[/COLOR]HatchGroups, 1,				// group list and # of groups 
		_V( 0.394,-0.578, 1.661),		// rotation reference point 
		_V( 0.0, 1.0, 0.0),				// rotation axis 
		(float)-85*RAD					// angular rotation range (converted to radians)
		);
	
	anim_Hatch = CreateAnimation(0);
	AddAnimationComponent ( anim_Hatch, [COLOR="red"]0.0f, 1.0f,[/COLOR] &Hatch);

It seems that replacing the mesh index with the mesh index's number was the critical change yet the documentation does not explain why this may be.

It seems that replacing the mesh index with the mesh index's number was the critical change yet the documentation does not explain why this may be.

And did `mesh_AS` contain 3? Wasn't it working when you just changed `HatchGroups, 2` to `&HatchGroups, 1`? The mesh index argument is passed by value, so it shouldn't make any difference when it's a variable or a literal, if their value is the same.
