Hi,Happy new year!
I have a dialog plugin with 2 buttons. One decreases the texture projection length, the second increases it (in steps of 10).
This works, but it I cannot see the changes on the object immediately. I have to deselect my texture tag and select it again. Then the viewport is refreshed.
I'm sure that I've added the EventAdd() method at the end and that this method is executed.

Try calling op->Message(MSG_UPDATE) for the object after changing the texture projection length and see if that helps activate the changes automatically.
I assume that you are doing COFFEE in an XPresso node?

Hmm, the simple Message method on the object didn't work. Only the first time the object really was refreshed.
I changed the line to
> doc- >MultiMessage(MSG_UPDATE);
and now it works. Strange... -

Howdy,
I was advised by Paul Everett to never send a MultiMessage() to the entire document because it can cause some serious overhead. :o(
Have you tried using EventAdd(EVENT_FORCEREDRAW)? I'm not sure if that works in coffee like it does in C++, but that's what I've used.
Adios,

Hey, thank you Cactus Dan for the hint. EVENT_FORCEREDRAW does work in COFFEE but it is not a solution to my problem.

Now, if I add the MultiMessage(MSG_UPDATE) methode before the EventAdd(), it works. But if I remove EventAdd(), it won't work at all.
AND, this method only works in C4D 10.5. I can add as many MultiMessages as I want in 9.1, the view will not be refreshed.
Any ideas?

Howdy,
Well, I'm not sure about coffee, but in C++ while a dialog is open, to get the view to refresh, you can also call:
> _
> DrawViews(DA_ONLY_ACTIVE_VIEW|DA_NO_THREAD|DA_NO_ANIMATION);
> _... but this may not be available in coffee. :o(
Will coffee create a SceneHook plugin? I've also used a SceneHook plugin with C++ for drawing in the view while a dialog is open.
Adios,

DrawViews() is definitely not available in COFFEE.
Have you tried to get the Texture tag and/or Material and send Message(MSG_UPDATE)'s to them? It really isn't the object that is changing, it's the material. This might explain why MultiMessage() works - it broadcasts the message to everything in the document including materials. Keep the EventAdd() as well.
Can't help with differences between R9 and R10.

Ok, I'm going to try sending a message to tag and material right now.
BTW, what is the difference between EventAdd() and the message(msg_update)? They both do the same thing, no? Notifying cinema that something changed and that the viewport needs no be refreshed?

Howdy,
Well, I think Message() just sends a message, by calling the Message() function of each node and EventAdd() adds a global event.

The only thing that really works is sending an update to the document every time.

Have you considered C++?
Although the MultiMessage() is not recommended, if it works continue using it. Though it's not good that it doesn't work in R9 at all.
Another possibility is to do what you said you needed to do manually - deselect and reselect the tag. This can done in COFFEE by setting the BIT_ATAG with SetBit(), DelBit(), ToggleBit(). The problem is that I don't think that these work in R10 - because R10 has made these deprecated for a new set of flags and COFFEE isn't up-to-date to use them.

I heard people say that we have to push Maxon into putting more time into the C.O.F.F.E. developpment, and now I know why. Thought that it could handle such easy things like changing the projection of a material with a button.
On the other hand this might be a good occasion for taking a look into C++ (which I once learned in school, but that was a loong time ago)
I tried to use the
> doc- >SetActiveTag(obj, tag);
method to select a tag, but it seams that COFFEE doesn't provide a way to select NO tag. -

As already menshioned, this works only for the first time. After that I have to select and deselect the texture tag to make the changes happen. Selection/deselection another object doesn't refresh the scene, only selecting/deselection the texture tag.I tried several way of doing the refresh in C++.

I even tried to do the select/deselect mannually as stated by Robert, but none of these work. Only the first time they work.And since C++ has no MultiMessage() Method I don't know how to make the changes except deleting the texture tag and creating a new one with the new projection.

To change the projection here, you need to use something like this:
tag- >SetParameter(DescLevel(TEXTURETAG_PROJECTION), GeData(TEXTURETAG_PROJECTION_UVW), 0L);
You'll find that some parameters can be set using its BaseContainer while others require using SetParameter(). The latter case mainly for parameters displayed in the Attributes Manager which are stored in Description resources.
A better way to work with BaseContainers in C++ is this:
BaseContainer* bc = tag- >GetDataInstance();
bc->SetX(id, value);Hope that helps!
