Iv tried a number of things, returning anything for extractEnergy dosen't change anything.
As for the javadoc, unless this is what you are speaking of.
/**
* Remove energy from an IEnergyHandler, internal distribution is left entirely to the IEnergyHandler.
*
* @param from
* Orientation the energy is extracted from.
* @param maxExtract
* Maximum amount of energy to extract.
* @param simulate
* If TRUE, the extraction will only be simulated.
* @return Amount of energy that was (or would have been, if simulated) extracted.
*/
That doesn't help much at all, sure I understand what each one does but I can't get anything to output.
