Just been trying out Mother (www.onar3d.com/mother/) today and it seems very nice, although I miss more documentation and a way to debug.

I have been running some simple exported sketches that have worked nicely, but I seem to be doing something wrong with this one. This code runs fine in Processing but makes Mother crash. Anyone got any idea?

cheers!

Well, Mother is not a library but a standanlone program to VJ .jar files made in Processing. It has a library called Foetus when used in Processing - but I agree, its probably more correct to place it here. Thanks.

no, thats the problem. The code runs fine in Processing, but not in Mother. And there are no error messages to be seen from Mother. I dont believe Mother has any error reporting system. postln() messages does not get through to the client (MaxMSP / PureData) used to control Mother either.

I thought that there maybe was something simple I was overlooking that someone with sharp eyes could point out....

ok, so now my code doesn't crash Mother but it only shows as a black layer. Running it in processing in the same size gives no error and runs smooth.

Im very happy for any input!

cheers,
