Ununennium
Cache selectors in commands to let Minecraft go brr
Ununennium caches selectors (predicates) you can use when executing Minecraft brigadier commands. The mod may greatly improve the performance of function datapacks that execute many commands in one tick because the selectors are cached and don't have to be evaluated a bajillion times in a tick.
FAQ
Q: Will anything break?
- A: It depends. In rare cases, caching may cause unexpected behavior if you rely on selector results changing within the same tick. For example:
This only affects commands run within the same tick. On the next tick, the cache refreshes and the command will work as expected.# This will now load it into the cache execute as @e[tag=nice_tag] run say hello # We'll add a tag here tag @p add nice_tag # We'll try to execute this here and it will just not do it because of the cache. # If it was executed next tick it would've worked because of the refreshed cache! execute as @e[tag=nice_tag] run say THIS WILL ONLY BE VISIBLE AT THE NEXT EXECUTION
- A: It depends. In rare cases, caching may cause unexpected behavior if you rely on selector results changing within the same tick. For example:
Q: Will this change my datapacks or world?
- A: No, the mod does not touch any files nor does it modify your datapacks/world.
Q: Datapack XY doesn't work, what to do?
- A: Please create an issue so it is easier to track and fix!
