Maybe I'm nuts... when I try to use CallCommand within an expression, Cinema4D freezes.For example:
main(doc,op)
{
CallCommand(13957); // Clear all console entries
}Doesn't work
Regardless of which command I try to call, it freezes.Is this a bug?
Thanks,

I have that CallCommand working in a settup of mine.
Try add a Println() : either static or another variable, after the Command so cinema has something to delete for each Event.Cheers

Hi Lennart
Thanks for the reply. But the println doesn't stop C4D from freezing
It seems as if CallCommand doesn't work with expresions.Umpf

It's dangerous to use CallCommand() within an expression, since the command you call may well trigger the scene to be redrawn in which case the expressions are evaluated again. Then you will have an infinite loop, freezing CINEMA 4D.

Jup. That's why I called a command which shouldn't force the editor to be redrawn: 13957 - clear all console entries.
But also if I write some code which don't let CallCommand() be executed multiple times (only the first time, then a bool variable is set which avoids executing CallComand the next time) I get the freeze.
Thanks,

Hm, it could be because the expression is executed in a thread. So GUI functions, such as dialogs, are not allowed for that reason. And "Clear All Console Entries" seemingly belongs to the same category, as I suspect many callable commands do. So using CallCommand() from an expression is not safe.
A workaround is to put the code in a menu plugin instead.
