[mod] Tree Cutter [woodcutting]

I know there are already some tree-cutter mods, but I decided to write my own from scratch that does match my needs.

Woodcutting

Mine the first tree node from a tree while the sneak key is pressed, then wait till the whole tree is breaked down and in your inventory. The process can be stopped by pressing sneak key again. This is useful in jungle because no tree shape determination is implemented so all touching tree nodes are a single tree (could be half of the jungle :-().

Highlights / Features
  • Lag-free because the work is not done at once. You can observe the woodcutting.
  • You can stop the woodcutting by press sneak key second time
  • You can add additional trees to process by digging other tree nodes manually
  • The distance to the player is used to prefer next node so the player can partially influence the work direction on big areas
  • The auto-mining speed is dependent on wielded tool, so the diamond axe is still advantageously than empty hand
  • All checks and functionalities are processed (like hunger damage and tool wear) as if the player did the mining manually
  • Really nice effect in combination with item_drop mod
  • Does work with all trees in Item group "tree" and "leafdecay" leaves and fruits
  • Simple HUD message about woodcutting process status if active
  • For developers - an enhancement API (See README.md on github)

This is already one of my favorite mods. However, I recommend adding options for a few sanity checks.

(1) An option to stop cutting after the player's axe wears out. You might let it keep cutting for a while, just to avoid uncut treetops, but it should stop eventually, otherwise someone could conceivably defoliate an entire region with a wooden axe.

(2) An option to stop cutting when the player's inventory fills up. Once you're full, all the cut nodes drop individually, making a terrible mess and taking forever to clean up if you just forgot to hit sneak again.

(3) An option to stop cutting after a large number of nodes or after so many nodes are cut in a period of time.

I thought of these while testing woodcutting on a giant tree.

Image

At about the above point, my wooden axe disintegrated and my inventory was full. Nodes started raining down on me, along with the occasional angry treeman. (My game gives you a tiny chance of summoning one when you cut any wood.)

Image

Still humming along. My log is filling with digging messages and deleting too many nodes messages. As you can see below, it chops down the roots for quite a way. It can't get the whole tree because the top and bottom haven't even been built by the mapgen yet.

Image

I may have to move a bit, but I think it's going to get most of the tree.

Thanks for the feedback.
I noticed the disabling by sneak key works only if the key is pressed during a node is digged. So I added a hud message as "Woodcutting active. Hold sneak key to disable it" as indicator for active process.

I like the option to swich the axe during the cutting process is working, because of hunger damage I like to eat apples to not to starve. :-/

Feel free to create PR's for restrictions as you need it: optional. I like the way the player decides if the cutting process is done. I added one restriction: Stop the work if the player dies

wooo, duane what have you done?

Ok, second restriction: Maximum distance to the player is set to 100 so the woodcutting is stopped if you run away.

Site-note: I plan to rewrite the core functionality next days to reusable class so different tools could use it with different parameters

As usual I did a rewrite after the first version was working ;-) Now with new bugs and features in objects style.
Some hooks are implemented to be able to customize the mod for subgames

Code: Select all

woodcutting.settings = {
	tree_distance = 1,   -- Apply tree nodes with this distance to the queue. 1 means touching tree nodes only
	leaves_distance = 2, -- do not touch leaves around the not removed trees with this distance
	player_distance = 80, -- Allow cutting tree nodes with this maximum distance away from player
	on_new_process_hook = function(process) return true end, -- do not start the process if set to nil or return false
	on_step_hook = function(process) return true end,        -- if false is returned finish the process
	on_before_dig_hook = function(process, pos) return true end, -- if false is returned the node is not digged
	on_after_dig_hook = function(process, pos, oldnode) return true end, -- if false is returned do nothing after digging node
}
Please note: in on_new_process_hook(process) it is possible to redefine the woodcutting process methods like

Code: Select all

process:get_delay_time(pos)
process:check_processing_allowed(pos)
process:select_next_tree_node()
process:show_hud(pos)
and other process methods

Anything missed before release?

First post updated, screenshot added. On github README.md is now a full API documentation for possible enhancements

EDIT: Added hook examples https://github.com/bell07/minetest-wood ... amples.lua
- Change the hud message trough method redefinition in on_new_process_hook
- Count the cutted tree nodes and stop after 99 in on_after_dig_hook

After actually using this mod I can say for certain that it is really well done. I'm so glad that I won't have to have tree tops dotting the landscape that I can't reach any more.
In fact I liked this mod so much that I went ahead and recorded a video for it. http://nathansalapat.com/minetest/woodcutting

Many thanks for your review! It is an honor for me to be on your review list.
For your question: The counter in the HUD message is the current todo-list size. The mod does not capture the whole tree/region for cutting at once but checks for related neighbors nodes each digged node. So in case of pine wood it is mostly 1 per tree if only the nodes above are not cutted, or it is 2 if node above and under the digged is still in the world. The counter becomes interesting in jungle region because of many connected trees and tree nodes with more then 2 neighbors.

I like this mod very well done. One setting I would like is to ignore collecting of leaves. After a while you have leaves scattered all over the landscape. So a setting to stop leaf collecting would be ideal.

One of my intentions was to collect leaves for compost and homedecor's oil and plastic ;-)

But now I added the requested setting defaulted to true:
minetest.conf:

Code: Select all

# If enabled the woodcutting dig not connected leaves
# after tree nodes removed
woodcutting_dig_leaves (Dig leaves) bool true
For developers: accessible from other mods:

Code: Select all

woodcutting.settings.dig_leaves = true
or dynamic/per process:

Code: Select all

process.dig_leaves = true
(README with Hooks/API updated also)

This is great! Now I can cut down all the jungles... I hates them :D
Could you do a mod which spreads a disease to all jungle trees next? (j/k).... kinda

Such a mod exists already, it is called "fire" ;-)
If you like to do it with woodcutting, just change the setting

Code: Select all

	tree_distance = 1,    -- Apply tree nodes with this distance to the queue. 1 means touching tree nodes only
to a higher value (to 2 or 3?) in the line 4 in init.lua.

Great mod! Tested it out on my Testing Survival (Not very creative name, I know.) world and came to find that it's decently fast with a steel axe.

I had just upgraded both woodcutting and hbhunger on the same day. Here's what I posted in the hbhunger forum. Sorry for crossposting, but it seems as either of these mods, or the combination of them is the cause.

In the short time after that post and this one, I have isolated that cutting 1 redwood tree triggers it. Clean start of minetest 5.0.1 client, fresh join, cut one tree with no other actions prior, and the lag starts. Client side only.

And here's another issue. Client side lag -- massive. I haven't been able to track the action that triggers it, but in most cases, it seems related to either hbhunger and woodcutting. Both mods were updated on the same day, and the lag issue with the next player to join after restarting the server.

Server 5.0.1 via ppa.
Clients 5.0.1 (most of my players run the Windows 64 version)

Redwood?

We have no problems, but don't have the mod (moretrees?) installed that gives redwood. As I recall, one of the tree mods gave us massive lag, and I don't think we ever isolated what the problem was.

For what its worth, redwood trees are in the ethereal mod. :)

I had also said that it was a 'client side lag issue'. Server status max_lag was always less than 0.6. But the client could not open doors, chests, move, or even chat, without a 2 to 5 minute delay. When this happened, only the player that cut a tree experienced that lag problem. Clearly not a server issue, except for the possibility of conflicts with other mods.

However, further tests seem to be pointing to the hbhunger mod. Both woodcutting and hbhunger were updated on the same day. Disabling woodcutting did not stop the issue, but reverting to my older version of hbhunger seemed to bring things back to normal.

I should have made this suggestion a year ago. Changing the activation key from 'sneak' to 'aux1', allows for players to use the shift/ladder trick to climb trees, without cutting down the tree.

Only requires the change in 2 lines. One for the activation key (line 321), and one for the description text (line 272).

Drawbacks: Mobile app players may not be able to use the aux1 key.
