Subject: [PATCH] Fire BlockPistonRetractEvent for all empty pistons
|
|
|
|
There is an explicit check in the handling code for empty pistons that
|
|
prevents sticky pistons from firing the event. However when we look back
|
|
at the history we see that this check was originally added so that ONLY
|
|
sticky pistons would fire the retract event. I'm not sure why.

|

|
|
|
Over the course of several updates, the meaning of that field appears to
|
|
have changed from "is NOT sticky" to "is sticky". So now its having the
|
|
opposite effect. Only normal pistons fire the retraction event. And like
|
|
all things in CB, it's just been carried around since.
|
|
|
|
If we are to believe the history, the correct fix for this issue is to
|
|
flip it so it only fires for sticky pistons, but that puts us in a
|
|
bind. It's already firing for non-sticky pistons, changing it now would
|
|
likely result in breakage. Furthermore, there is little documentation as
|
|
to WHY that was ever intended to be the case.
|
|
|
|
Instead we opt to remove the check entirely so that the event fires for
|
|
all piston types.
