I've looked at all the classes... I'm not just being lazy
I can't find anything to do what I want. There are motorDownPressed,message1Pressed etc. but no unpressedMethods. I've looked at the opcodes and there are none to indicate unpressed, at least that I can find.
The only thing I can think of is the NONE opcode from the RemoteControlMessenger class, which still isn't ideal since it will be called when any button is unpressed... to try implement that I'd have to override the lejos built in remote control sensor class.
Please if anyone knows how to this easier let me know, it's important that I find out in the next day. I'll try to avoid implmenting it the way I think I might have to at the moment, but if nessacary I will try it.
