    User Information:
    Cinema 4D Version:   10.5 
    Platform:      Mac OSX  ; 
    Language(s) :   C.O.F.F.E.E  ;

    ---------
    I am trying to write a little script which checks on the disk for a file to be written, then read the values and uses in a xpresso network.
    I am starting now.
    First task is check that the file is there or not.
    First trouble, the code I am writing does not work.
    this is it:

    > main() \> { \> \> var filename = ("test.txt"); \> \> var a = FALSE; \> while ( a == FALSE){ \> println("the file is not there"); \> //something is wrong here: \> a = GeFileExist(filename, FALSE); \> //what is it? \> } \> \> println("Now the file IS there"); \> } \>

    I am sure it's a simple thing but I am not yet familiar with coffee.
    Could you help me?
    Thanks

    If this is in an expression, it won't work as COFFEE Expressions cannot do any form of file system access (for security reasons). The way to go then is to create a COFFEE plugin (say, a CommandData plugin).

    Also, realize that the Filename 'filename' should be a full path. Relative paths don't work ... or may only refer to the current working directory set up by Cinema 4D - that is, the Cinema 4D install folder (you'll have to check this).

    thanks, would be the plugin accessible through the xpresso interface?
    what ultimately I am looking for is:
    and external applications generates a string of values in a file.
    Cinema is open and checks for the file to be written.
    As soon as the file changes the file is read and values fired in a xpresso network, which is used to simplify parametric modelling...
    is this possible at all?

    If I write a COFEE plugin, would this be a module in the xpresso network or something else?

    Thanks again
    G.

    I don't think this is possible in COFFEE.

    so shall I use C++?
    or is it not possible at all?

    rui_mac wrote an expresso block which reads and writes texts... it was on a magazine in 2005... unfortunately the code is encrypt...

    would it be possible, by having such an xpresso block, to say something like:
    if the frame is [0], look for this file, if the file exist read and if not keep looking for it,   take values and do something, start again.

    please help :-)

    thanks
    G.
