I dont know why this happens all the time but when Im programming in FlowStone-Ruby it happens that I get this error:

NoMethodError: (in method 'event') undefined method '/' for nil:NilClass

And yes the var is a Number: lty = @ins[16] / 2 - Input 16 is a float. If I reconnect the ruby-comp and paste the EXACTLY same code I dont get the error again


Hope my english is not too bad greetings, Marvin

It happens probably because the array @ins is not fully initialized, when the event comes in.

BTW: you don't need all the "xyz = @ins[n]"... when your connectors are named, you can directly access them with their name, eg. @ltx, @lty, @rtx,... also you should think about the triggers that call the event procedure. Right now you execute all the code in event, when any of the input changes. Since you've got a high frequency trigger connected to this, you probably don't want this, and only execute that code, when the trigger comes in. So you can wrap everything in event like this:

Ok Ill change some things but I need all the stuff in the event... (XBox360 Controller).
But how can I initial @ins correctly?

PS: thanks for the fast answer but wasnt at home
