Hi, I have a question about threads.What is a thread? Yes, I should know it before developing a plugin ;).
Today my plugin begins to freeze cause C4D waits for the result of a calculation from an external application. In which case is it useful to create a thread?
It's correct that a thread get a seperat stream for storage and the processor? Should a new thread solve my problem?
Thx4help

Hi!
I red a lot of things about thrads and I think a thread could solve my problem. Does someone now where in the SDK or documentation I am able to find an example?
I have 3-4 commands that I have to put in a seperat SingleThread. The synchronisation is required when the commands are finished, like a return value.
But I don't know how.
I found the MPthread in the SDK, but it's not the right thing I am looking for.
Bye

Hi,
I would recommend looking on the example source files which comes with the SDK, e. g. gui/menutest.cpp.
Cheers.

Hi! MnuTest is for Multiprocessing Threads.
I thought I have to look for the Thread class, and not for the MPThread!?Thanks

For Multiprocessing threads (which are parallel on multi-processor systems), use MPThread. This would be mainly useful for rendering and won't be of any use on a single-processor system (you can't do multiprocessing threads here).
For single-process threading in Cinema 4D, use a class derived from Thread. These can be used regardless of number of actual processors/cores.
There are no examples (as far as I know) in the cinema4dsdk plugins folder. There is, though, much information here (a Search of "Thread" by Message Body yields 27 pages). I realize that wouldn't be as good as an example but there are probably some of these messages with code one would hope.

Hi!
Yes, thanks, that's the problem I found with the difference between MPThreads and SingleThreads. I have to use it for calculations in Xpressonodes, so MPThreads aren't the code-lines I need.
Thanks for help. I try a search.
P.S: If somebody has some code examples, I would be pleased to get some code-snippets... Thanks

Hi!
I found some code lines, could they be correct? I create a new class at first with constructor thread

Where do I have to create this class now? I tried to call it when the code is needed.
CacheThread ct;
ct.Start(TRUE,THREADPRIORITY_NORMAL);
ct.End();
ct.Wait(false);But C4D crashes ever and anon...
