Allows trees to be chopped down by repeatedly breaking a single block. The whole tree will only break after a certain number of chops, and bigger trees require more chops. Inspired by mods like Treecapitator.

Versions available (Requires Forge):

1.16.5/1.16.4/1.16.3
1.16.1
1.15.2
1.12.2 (currently missing some of the fancier graphical features)

Things to consider when lumberjacking:

Chopping trees doesn't require an axe, but will take a while without one
Chopping different blocks of the same tree will all contribute to bringing down the tree
Players can work together to chop down those big trees
Bigger trees require more total chops, but fewer chops per block*
Hold "sneak" when breaking a log block to break it normally

*By default, the number of chops required to fell a tree is computed logarithmically. Some example numbers are below. The number of chops can also be configured to scale linearly with the number of blocks to, for example, require one chop per block, or one chop per tree. More information can be found here.

Tree blocks	Chops required
1	1
3	3
5	4
10	7
20	12
50	19
100	25

Cool features:

Doesn't get too loud when breaking big trees
Works on mushrooms and fungi
Intelligently breaks leaves
Compatible with most modded trees

FAQ:

1. How do I turn off chopping?
Press n to open TreeChop's in-game settings, then toggle off the "chopping" setting. A key can also be bound to toggle chopping without opening the settings screen; go to Options > Controls and find the section labeled "HT's TreeChop".

2. How do I keep chopping off and only turn it on while sneaking?
By default, sneaking inverts your current chop setting, so just toggle chopping off (press n to access the settings screen) so that chopping will be enabled by sneaking.

3. How do I keep chopping even when sneaking?
Press n) to open TreeChop's in-game settings, then toggle off the "Sneaking inverts chopping" setting.

4. How do I keep from chopping my house down?
There's a setting to disable chopping if the "tree" is not connected to leaves. Press n) to open TreeChop's in-game settings, then toggle "trees must have leaves".

5. I started chopping my house down. How do I stop?
If you find yourself chopping a block when you just wanted to break it normally, try breaking the block while sneaking, or toggle off chopping (press n to access the settings screen).

6. I was chopping something and the game crashed! What's up with that?
Probably the item you used to chop the tree doesn't play nice with TreeChop. Go to [your minecraft folder]/config/treechop-common.toml and add the item's registry name to choppingToolsBlacklist, or ask the server owner to, and then maybe let me know about the conflict and I'll try to fix it.

7. Why can't I chop anymore?
Maybe chopping is turned off; press n to open TreeChop's in-game settings, then toggle on the "chopping" setting. If chopping is enabled and changing tools doesn't help, then there might be a conflict with another mod. If you send me a recent log, I'll try to fix it.

8. Why do some trees leave behind floating leaves when felled?
Either
a) it's a modded tree and its leaves are not set up properly. Let me know what type of tree is misbehaving, and I'll politely inform the mod owners.
b) there are too many leaves! You can increase the max number of leaves by going to [your minecraft folder]/config/treechop-common.toml and increasing maxLeavesBlocks.

9. Why do some trees leave behind floating logs when felled?
Either
a) it's a modded tree and is weirdly shaped. Let me know, and I'll try to make TreeChop do a better job of detecting that type of tree.
b) the tree is too big! You can increase the max tree size by going to [your minecraft folder]/config/treechop-common.toml and increasing maxTreeBlocks.

10. How do I disable mushroom and fungus chopping?
Go to [your minecraft folder]/config/treechop-common.toml and change
blockTagForDetectingLogs = "treechop:choppables"
to
blockTagForDetectingLogs = "treechop:choppables_except_mushrooms"
If you want more control over which blocks can be chopped, you have to make your own datapack and fiddle with the block tags (see https://minecraft.gamepedia.com/Tag for more info).

12. Why am I not seeing the [fill in the blank] feature?
Only the newest version of Minecraft 1.16 is fully supported. Some older versions, especially 1.12.2, lack some of the fancier features.

11. Can I include this in a modpack?
Yes!

Known bugs in 0.14.4:

Compatibility issues:
- Some modded trees leave behind leaves when felled; this is usually either because some mods don't set up their leaves correctly, or because they mark their leaves as non-decayable to allow for weird shapes. See https://github.com/hammertater/treechop/issues/44
- Some modded items have conflicting behavior with treechop. See https://github.com/hammertater/treechop/blob/main/docs/compatibility.md#compatibility
