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

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 withobjt[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??
switch (dcu->id[0].id)
{
case DPT_BASE_FOUND:
dragged = (BaseObject* )dcu->element;
return TRUE;
}
}
return TRUE;

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,
