1.3.3 and above, the order that you apply filters to regions affects their behavior.
Here's an example.
Let's start out with a basic filter that denies everything except TNT.
Now let's apply this filter to
Region A, and also apply a filter to
Region B that denies all blocks.
However, there is one slight complication.
Region B is inside of
So which filter will override the other? This is where the apply order comes in handy.
The order that you put the
<apply>'s can change the outcome when something gets filtered.
In the previous example, the
only-tnt filter would always override the
never filter since it is above it.
The apply for
region B won't get checked since it overlaps completely with
region A and
region A never returns abstain.
If we changed the order of the filters:
Now you cannot place blocks in
Region B, but outside of it in
Region A you can only place TNT blocks.
Although this may not be an issue for many maps such as a Blitz map or a TDM,
this is a crucial concept for many DTC/DTM/CTW maps that use the
Usually it's best to have the
<void/> filter at the lowest priority (at the bottom of the list).
