//NOTE (KGP): I've laid the groundwork for AvHTechNode to potentially become an abstract
|
||
|
|
// interface so that it can be subclassed separately for Client and Server instead of having
|
||
|
|
// #defines on the client side. The AvHMessageID is now a static field meant to uniquely
|
||
|
|
// identify the node within the tree; this greatly simplifies the AvHTechTree class. This
|
||
|
|
// has a side effect--assignment from another AvHTechNode doesn't change the AvHMessageID.
|
||
|
|
// When you want to create a copy of an AvHTechNode, use clone() instead of equality--this
|
||
|
|
// also eliminates the problem of slicing from the copy.
|
||
|
|
//
|
||
|
|
// The ability to subclass AvHTechNode also allows for a playtest configuration subclass
|
||
|
|
// that automatically self-updates when the relevant fields are updated; this is something
|
||
|
|
// I think is defintely worth doing for a couple days' work; it would completely replace
|
||
|
|
// the BalanceChangeListener functions of AvHTechTree below with a system that only changes
|
||
|
|
// components as necessary, which is much less CPU intensive.
