Hey all,

I'm trying to write a script that watches a folder and looks for new C4D files. Once it finds a new file it should add the file to the render que. The code works fine in an external editor, however in C4D it doesn't work. When I run the script and add a new file to the watch folder, C4D hangs and I have to restart it.

Does anyone have a clue why? See the code below.

Greets,
Hans Willem

import c4d
import os
import time

def watchFolder() :
    before = os.listdir('/Users/blabla/watch folder')
    while 1:
        global newFiles
        time.sleep(3)
        after = os.listdir('/Users/blabla/watch folder')
        newFiles = list(set(after)-set(before))
        if len(newFiles) > 0:
            renderFile()
            break
            before = after

def renderFile() :
    for i in newFiles:
        if i[-3:] =='c4d':
            # then some code here to add the file to the renderque and start rendering
    watchFolder()

watchFolder()

Of course it hangs, because you block the main thread. Put your code into a threaded environment.
For R13+, see the c4d.threading module which works afaik fine in the Script Manager. For R12, you'd need to write a plugin that uses the built-in threading module.
