Hi,
how can I rotate the tangents of a bezier spline? I don´t know how to handle the tangent[x].vl and .vr vectors. In cinema it´s definetly easier ;)
Thanks
Samir

Just treat them as ordinary vectors in object space. How exactly do you want to rotate them?

well, I am calculating a rotationvector from a splinetangent with:
Vector rot = obj->GetSplineTangent(obj->UniformTonatural(x*(lenght/4)/length),0);
Now I want to rotate the tangents with this rotationvector.
I tried this with
objt[0].vl *= rot;
objt[0].vr *= rot;
but that doesn´t work.

Use ^= since vl and vr are vectors not points. And I see no rotation matrix, just a rotation vector. (vector * vector = dot product) Use RotAxisToMatrix() before multiplying.

thanks I will try that. And another question without the need to open a new thread.
I have a LINK Description for my plugintag, but how to retrieve the dropped object?
Thanks

or of a string field from a STRING description.
String str = data->GetString(ID); or
String str; data->GetString(ID,str);
do both not work.

I tried this but it doesn´t seem to work either. In the doc example there is a t_data instead of my data, but I have no clue what it is good for. Help please...
Bool DPTransfer::Message(GeListNode *node,LONG type,void *data)
{
if (type == MSG_DESCRIPTION_CHECKDRAGANDDROP)

DescriptionCheckDragAndDrop *dcu = static_cast<DescriptionCheckDragAndDrop*>( data ); //t_data??

ok sorted it. It works exactly like that. Only my fault. :)
Thanks anyway for looking. g*

Hi All,
Works for me to sofar, but here you check for a object hoovering above the Link. It can be used to accept or refuse the hoovering object.
Now, how do i find out when the object is finally dropped.
There seem to be no message for that.
Thanks

Wouldn't that be an ordinary SetDParameter() call?

Hi Mikael,
Thanks for your answer but a GePrint("Bingo") does not appear in my console with the SetDParameter() call.
A lot of Bingo's in the tags Message function, listening to MSG_DESCRIPTION_CHECKDRAGANDDROP on hoovering.
(i have a Description res Linkbox, its for the AM)
What am i doing wrong?
Thanks,
