i've just installed the public beta and wanted to try out that new feature. with C-Script i get:
Parameter unknown NOSEND_Z Parameter
but it looks like i can use it in lite-c (though i have no network script to test it right now). The manual doesn't say that it's lite-c only, so could you please add it to c-script?
Yes, I forgot a [LC] in the manual - it's fixed now.
You can not test NOSEND_Z with C-Script, and I do not recommend C-Script for an online game anyway. But you can easily test NOSEND_Z with the multiplayer tutorial.
