My goal is to write all subanim values of an object to a file. So far I can get values from the controller assigned to a subanim like this:
void SaveSubAnims(Animatable* subAnim)
{
for (size_t i = 0; i < subAnim->NumSubs(); i++)
{
Animatable* childSubAnim = subAnim->SubAnim(i);
if (childSubAnim)
{
TimeValue time = GetCOREInterface()->GetTime();
Control* controller = (Control*)subAnim->GetInterface(I_CONTROL);
if (controller)
{
switch (controller->SuperClassID())
{
case CTRL_FLOAT_CLASS_ID:
{
float val;
controller->GetValue(time, &val, CTRL_ABSOLUTE);
// Writing val to the text file ...
break;
}
// Checking other Cases ...
}
}
}
SaveSubAnims(childSubAnim);
}
}
But, How we can get value from a parameter which doesn’t have any controller assigned? for example Radius?

you need the paramblock(s) –> GetParamBlockByID(…)
and then you need the paramid of the radius
following will dump infos about every param in a pblock, no need for controllers
//-----------------------------------------------
void dumpParamBlocks(Animatable* anim, TimeValue t, const std::wstring& fileName)
{
if(nullptr != anim)
{
FILE* f= _tfopen(fileName.c_str(), _M("w"));
int i, nBlocks = anim->NumParamBlocks();
for(i=0; i<nBlocks; ++i)
{
IParamBlock2* pBlock = anim->GetParamBlock(i);
if(nullptr != pBlock)
{
int id, nParams = pBlock->NumParams();
for(id=0; id<nParams; ++id)
{
ParamID pid = pBlock->IndextoID(id);
ParamDef pDef = pBlock->GetParamDef(pid);
if(pDef.size > 0)
{
std::wstring type = _M("<unknown>");
std::wstring value = _M("<unknown>");
switch(pDef.type)
{
case TYPE_FLOAT: type = _M("TYPE_FLOAT"); value = std::to_wstring(pBlock->GetFloat(pid, t)); break;
case TYPE_INT: type = _M("TYPE_INT"); value = std::to_wstring(pBlock->GetInt(pid, t)); break;
case TYPE_BOOL: type = _M("TYPE_BOOL"); value = (pBlock->GetInt(pid, t) != 0) ? _M("true") : _T("false"); break;
// more param-types....
default:
break;
}
MSTR animatable = (pDef.flags & P_ANIMATABLE) ? _M("true") : _M("false");
if(nullptr != pDef.int_name)
_ftprintf(f, _M("pblock: %d, id=%d, name: %s, type: %s, Anim: %s, value: %s\n"), i, pid, pDef.int_name, type.c_str(), animatable.data(), value.c_str());
}
}
}
}
fclose(f);
}

Thank you for your reply, this is my test result:
pblock: 0, id=0, name: radius, type: <unknown>, Anim: true, value: <unknown>
pblock: 0, id=1, name: segs, type: TYPE_INT, Anim: true, value: 8
pblock: 0, id=2, name: smooth, type: TYPE_BOOL, Anim: true, value: true
pblock: 0, id=3, name: , type: TYPE_INT, Anim: false, value: -1
pblock: 0, id=4, name: body, type: TYPE_BOOL, Anim: true, value: true
pblock: 0, id=5, name: handle, type: TYPE_BOOL, Anim: true, value: true
pblock: 0, id=6, name: spout, type: TYPE_BOOL, Anim: true, value: true
pblock: 0, id=7, name: lid, type: TYPE_BOOL, Anim: true, value: true
pblock: 0, id=8, name: mapCoords, type: TYPE_BOOL, Anim: false, value: true
Radius should be float right?

What about custom attributes? Can we save them as well?
Apr 05, 2022 5:42 pm
radius could be TYPE_WORLD
win32 ui is using TYPE_WORLD, qt it will be TYPE_FLOAT, but need to check
paramID=3 has a blank name, that’s a retired param in teapot
custom attribs should be possible, but never used them

My question is what part of the animation graph we should save?
SubAnims?
Controllers?
ParameterBlocks?
Custom Attributes?
How many of this classes we have?
Apr 05, 2022 5:42 pm
this should handle the CA’s
ICustAttribContainer* cc = anim->GetCustAttribContainer();
if(cc)
{
int num_attribs = cc->GetNumCustAttribs();
for (int i = 0; i < num_attribs; ++i )
{
CustAttrib *ca = cc->GetCustAttrib(i);
if(ca)
{
IParamBlock2* pb = ca->GetParamBlock(0);
if(pb)
{
//repeat as above
}
}
}
}
though something is nagging at the back of my mind about an odd quirk of scripted CA’s and scripted plugins parameter blocks, It will probably come back to me.

Do you think it will cover all situations?

Qt shouldn’t be a problem
its also about paramblocks
only the controltype in paramDef is win32 only
