About this project
What does Timber Physics add?
This pack adds Timber Physics!
If you chop a naturally spawned Tree with an Axe, it will fall over!
Compatible with Custom Trees from other Datapacks
If you want to chopp Nether Trees download this addon.
Customisation Options:
- To get into the options do /trigger physicstimber.help
- Choose whether sneaking should not trigger the Timber or if it should only trigger when sneaking. (Player specific)
- Choose the max Size a Tree can have for Timber to be triggered. (Admin only option, global)
If you are wielding an Axe with Silk Touch, Timber will not trigger.
Technical info:
This pack can be very taxing for Servers and Clients when big trees are chopped! Keep that in mind.
Max Tree size options explained:
Small: [up to 15 Logs and 100 Leaves]
all Vanilla Trees that are not large Trees
Medium: [up to 150 Logs and 400 Leaves]
all Vanilla Trees
Large: [up to 200 Logs and 800 Leaves] <- Default Option!
most Custom Trees
Absurd: [up to 600 Logs and 2500 Leaves]
basically anything that´s not really ridiculous
If a Tree is larger than the selected Max size, Timber wont trigger for it. (It will not fall over)
How a Tree is defined:
- Having 3+ Logs and at least 1 Leaf that is non persistent ([persistent=false]) connected to one of the Logs
- Each Log looks for connected Logs (also diagonal) so if there are Logs in your Tree that have a one Block distance to other Logs they are not considered to be part of the Tree!
