Howdy,

OK, I understand how to browse through the descriptions, but I'm not sure how to get to the sub levels of the descriptions.

Can you provide simple example?

Adios,
Cactus Dan

Hello,

if you want to access the ID used to identify sub-structures of custom GUIs and datatypes you could simply load the description. Something like this:

  
AutoAlloc<Description> desc;  
if (!desc)  
 return false;  
  
desc->LoadDescription(DTYPE_VECTOR);  
  
void *browse = desc->BrowseInit();  
const BaseContainer *bc = nullptr;  
DescID tid, groupid;  
while (desc->GetNext(browse, &bc, tid, groupid))  
{  
 if(bc != nullptr)  
 {  
     GePrint("ID: " + String::IntToString(tid[0].id));  
     GePrint("Type: " + String::IntToString(tid[0].dtype));  
     GePrint("Name: " + bc->GetString(DESC_NAME));  
 }  
}  
  
desc->BrowseFree(browse);  

best wishes,

Howdy,

Well, to be more specific, I want to browse through the descriptions and get the Pose Morph tag's sliders. The sliders seem to all have 2 levels with the first level being 4000.

Here is my browse loop code:

while(desc->GetNext(h, &bc, id, groupid))
{
	if(id[0].id == 4000 && id.GetDepth() > 1)
	{
		LONG dID = id[1].id;
		GeData d;
		if(tag->GetParameter(DescLevel(dID), d, DESCFLAGS_GET_0))
		{
			if(d.GetType() != DA_REAL) GePrint("Not a DA_REAL");
		}
	}
}

But it prints "Not a DA_REAL" every time.

What am I doing wrong?

Adios,
Cactus Dan

Hello,

the pose morph tag is represented by a special class in the API: CAPoseMorphTag. This class allows you to loop through the sliders and to get their description ID:

  
CAPoseMorphTag* poseMorphTag = static_cast<CAPoseMorphTag*>(tag);  
  
const Int32 count = poseMorphTag->GetMorphCount();  
  
for (Int32 i = 0; i < count; ++i)  
{  
 DescID sliderId = poseMorphTag->GetMorphID(i);  
  
 GeData data;  
 poseMorphTag->GetParameter(sliderId, data, DESCFLAGS_GET_0);  
  
 GePrint("Slider Value: " + String::FloatToString(data.GetFloat()));  
}  

best wishes,

Howdy,

OK, but that's not available in R12. It's only there in R13+. To do it in R12, I have to go the browse route.

EDIT:
AHA! That is available in R12. It's just not listed in the R12 documentation. 

Adios,

Howdy,

OK, I have your code working where I can set the Pose Morph sliders, but I'm having a problem in my test code.

What I'm trying to do is create a clone of the object, then set each Pose Morph slider on the clone to 100%, compare the points of the morphed clone with the original object, and select the points that have moved, but it's not working.

Here is my code:

bool SelectMorphedPoints(BaseDocument *doc)
{
	BaseObject *op = doc->GetActiveObject(); if(!op) return false;
	BaseTag *tag = op->GetTag(1024237); if(!tag) return false;
	
	CAPoseMorphTag* pmTag = static_cast<CAPoseMorphTag*>(tag);
	
	LONG i, mCnt = pmTag->GetMorphCount();
	GeData sSet;
	
	// set all sliders to 0.0
	for(i=0; i<mCnt; ++i)
	{
		DescID sliderId = pmTag->GetMorphID(i);
		sSet = Real(0.0);
		pmTag->SetParameter(sliderId, sSet, DESCFLAGS_SET_0);
	}
	
	// clone the object
	BaseObject *clone = (BaseObject* )op->GetClone(COPYFLAGS_0, NULL);
	if(clone)
	{
		Vector *padr = GetPointArray(op);
		Vector *cpadr = GetPointArray(clone);
  
		BaseTag *clTag = clone->GetTag(1024237);
		if(clTag)
		{
			CAPoseMorphTag* cpmTag = static_cast<CAPoseMorphTag*>(clTag);
			if(cpmTag)
			{
				for(i=0; i<mCnt; ++i)
				{
					DescID sliderId = pmTag->GetMorphID(i);
					sSet = Real(1.0);
					pmTag->SetParameter(sliderId, sSet, DESCFLAGS_SET_0);
					
					clone->Message(MSG_UPDATE);
					
					BaseSelect *bs = ToPoint(op)->GetPointS();
					if(bs) bs->DeselectAll();
					
					LONG p, pCnt = LMin(ToPoint(op)->GetPointCount(),ToPoint(clone)->GetPointCount());
					for (p=0; p<pCnt; p++)
					{
						if(!VectorEqual(padr[p], cpadr[p], 0.001)) bs->Select(p);
					}
					
					if(bs->GetCount() < 1) GePrint(" no points selected");
					
					sSet = Real(0.0);
					pmTag->SetParameter(sliderId, sSet, DESCFLAGS_SET_0);
				}
			}
		}
		BaseObject::Free(clone);
	}
	
	return true;
}

It prints "no points selected" every time. Why is it not working?

Adios,
