i want to export the camera target...
with cinema 7 it works fine, with 8 i get a NIL object ?!
here the snippet:
// CAM TARGET
var objTag = pObject->GetFirstTag();
while(objTag != NULL)
{
var objClass = getclass(objTag);
if (objClass == TargetExpressionTag)
{
// TARGET NAME
var targetContainer = objTag->GetContainer();
var strTargetName = targetContainer->GetData(TARGETEXPRESSIONTAG_NAME);
println("camtargetame: ", strTargetName);
WriteChunk(CHUNK_CAMERA_TARGET_NAME);
WriteZeroString(strTargetName);
var tmpObject = g_pDoc->GetFirstObject();
while(tmpObject != NULL)
{
var strTmpName = tmpObject->GetName();
if ( 0 == strcmp(strTargetName, strTmpName) )
{
// TARGET POSITION
var vecTargetPos = tmpObject->GetPosition();
println("camtargetpos: ", vecTargetPos);
WriteChunk(CHUNK_CAMERA_TARGET_POSITION);
g_pFile->WriteReal(vecTargetPos.x);
g_pFile->WriteReal(vecTargetPos.y);
g_pFile->WriteReal(vecTargetPos.z);
}
tmpObject = tmpObject->GetNext();
}
}
objTag = objTag->GetNext();
}

Hi,
in R8 the target object is not a string anymore but a BaseLink. And baselinks are unfortunately not accessible anymore in R8 via COFFEE.
Either you switch to C++ or you will need to wait for an updated COFFEE SDK (or somebody writes a plugin that allows to pass the baselink to COFFEE - I even remember somebody actually is working on such a plugin).
There is no workaround for this afaik.

what do you mean by "up" vector? The rotations of the camera can be accessed just as any other object rotations with GetRotation or u use the local/global matrix of the object for the rotation values.
See the COFFEE docs for more information. (And maybe a good book about OOP ;)

i am coding an exporter for my d3d9 engine...
and there, the camera has an "eye" (cam-pos), "lookat" (cam-targetpos) and
"up" (?) vector... opengl also has those 3 vectors...
so my question is how to get that "up" vector out of cinema.

Get the matrix of the camera object. It sounds like:
var mat = cam->GetMg(); eye = mat->GetV0(); lookat = mat->GetV3(); // Z axis up = mat->GetV2(); // Y axisI assume that D3D doesn't store the X axis vector since it's always Y x Z.
