Could I use the source code for a fruit/nut mod I might start working on?

Heh. You can do what the fuck you want to with the code.

[VanessaE]

As Jordach implied, go right ahead and use whatever you want from it.

I tried to un pick the code but I cant find how to spawn the trees. I have a rough idea of how to define the tree shape but it needs clarification. are there and on-line tutorials you recommend I look at?

[VanessaE]

The Minetest API explains it for the most part, starting at line 1734: https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L1734

This site will help a little at making a model, but it renders strictly in isometric view, which might throw you off a little: http://www.kevs3d.co.uk/dev/lsystems/

Basically, trees are spawned by calling the API spawn_tree() function, you need only supply a position where the base of the tree will sit, and an L-Systems definition, both in the form of a normal Lua table. See moretrees/tree_models.lua for further examples of the latter. The Minetest engine will build the tree and place it according to the position and model you supplied.

[GreenGerm]

thanks! ;)

[GreenGerm]

I was going to ask you how to to make a node have an inventory but the API explains it all, thanks again.

[GreenGerm]

sorry to keep on bothering you but i would like some help with why the init.lua script wont work.

also would you recommend any graphic program? I'm currently using Gimp 2.6.

[Dan Duncombe]

Well, without looking at the code much, I would say it is generally a good idea to give mod node/entity names a lower case name. i.e. 'morefruit:kiwi' not 'morefruit:Kiwi'
Also, I think this may be an error (not sure if it makes a difference).
Try replacing 'tiles = {"Morefruit_Kiwi.png"},'
with 'tiles = { "Morefruit_Kiwi.png" },'

As for graphic programs I often use GreenFish Icon Editor for things like textures up to around 512x512 before it starts to be a laggy program. For awesome built-in textures I would say Serif Drawplus, but it costs ~£200 I think.

First, thank you VanessaE for this mod. The landscape is much more full of life (literally!) with it! :-)

In fact the problem that I am having here is because it works a way too good. :-) Much of the time, the trees grow together, with side-by-side trunks. I tried to alter "rarity" and "avoid_radius" on biome_defs.lua, with no results (screenshot below was taken after alter all avoid_radius to, at minimum, 10).



I'm using Minetest 0.4.7 stable with "moreblocks", "moretrees", "plantlife" and "vines" mods (downloaded last week). All trees, except beech are set to "true" on default_settings.txt.

Is there anything I can do to alter this? Or is this a normal behavior?

[VanessaE]

Minor update: moreblocks is now optional and can be disabled by changing a moretrees config setting.

If you've used moretrees stairs/slabs/etc. on an existing world, you need to update your moretrees_settings.txt file in that world's folder and add:

moretrees.enable_stairsplus = true

...somewhere in that file (say, at the bottom), to enable moreblocks explicitly. It's enabled by default on new maps, as usual though.

[VanessaE]

aracnus, I'm not sure why it's doing that. One or two others have mentioned similar issues, but it always seems to work perfectly for me. It must be some obscure bug in plants_lib since that is what handles actually placing the trees, but I'll be damned if I know what the issue is. Anyone got any ideas?

[Dan Duncombe]

I never get that, although sometimes with jungles, every single node up to around 20 nodes up is solid leaves or wood, making traversing the jungle difficult.

[Inocudom]

Would voxel_manip be useful for this mod?

[VanessaE]

L-system is used via a single API call to generate the trees, which the engine then passes internally to the vmanip code, actually. The slow part is the lighting updates - the trees code still uses "the slow way". This is already a known issue to the dev team, not sure what the plan is for fixing it.

Its very unlikely that the lighting of the engine is what makes this mod so slow.

[VanessaE]

PilzAdam: hmmmm has already confirmed that the main bottleneck is the lighting code.

The bottleneck of the L-System, but there is the whole Lua thing too, its not like that takes no time at all.

[VanessaE]

Well of course my mod takes some time, but I've benchmarked it in detail - something like 90% of the time is spent waiting for the engine to finish executing all of the spawn_tree() calls.

Item "moretrees:apple_tree_trunk_sideways" not defined.

crafts a box with "unknown texture" on it LMAO

[Neuromancer]

I'm trying to think of ways to easily improve performance until something can be done in the engine.
Is there an easy variable that can be set that just makes all of these trees spawn less frequently? Would that serve as a quick performance improvement? The trees tend to get a little too densely packed in some areas anyway.

[VanessaE]

Just edit biome_defs.lua and turn "rarity" up and "max_count" down on each of the trees you want to edit. You can turn the different types of trees off entirely by editing <minetestfolder>/worlds/<yourworld>/moretrees_settings.txt .

[VanessaE]

Update: New sapling textures contributed by Tim "Mitroman" Huppertz. License of all textures has been changed to CC-By-SA 3.0 (code remains WTFPL).

[VanessaE]

Update:

Added an option to spawn saplings instead of fully-grown trees at mapgen time. Such saplings will grow very quickly into a tree, compared to a planted sapling. Defaults to spawning saplings, which will sharply cut down the mapgen lag precipitated by this mod. This comes at the cost of not having the land be fully populated when you first get there, but since you can see where the saplings are, you can plan around them. You can always change it back if the lag doesn't bother you. :-)

Added a custom jungle tree sapling and aliased the default one to that, so that Moretrees will be able to grow its own jungle trees.

Fixed that damn tree density bug.

Be sure you update your copy of plants_lib also. Probably not necessary as it was just a readability update, but do it anyway. :P

[VanessaE]

Oops, dropped an obsolete alias, but that caused jungle trees to spawn without trunks! :D Fixed by altering the tree model to use the original node instead of the alias. Also fixed a forgotten spawn interval/chance for some of the new "_ongen" saplings.

[Neuromancer]

I took the sequoia leaves texture and used it in my bushes mod because it looks perfect on the bushes. I see that the textures are cc-by-sa 3.0. I believe that means I need to give credit to who created the sequoia leaf texture. Do you know who did, or better yet, can you just give me the blurb I need to put in my license file? I just improved the bushes mod and want to make it available.

Thanks much!

[VanessaE]

Most likely I got it from RealBadAngel since he and I worked on this mod together, but damned if I can remember for sure! :D

I think just mentioning it came from moretrees is sufficient.

[Ol]

This mod is just beautiful, thank you !

I crafted a coconut + drinking glass + old used bronze axe. And I get : coconut pieces, a glass of coconut milk and my old axe replaced by a was brand one !

I haven't tried with another axe. But the result is surprising, is it a bug ?

Using official 0.4.7 stable + latest Moretrees.

Ol

[VanessaE]

It's not so much a bug as my not knowing how to restore the axe to its former status. I don't think there's a way to do this from a craft recipe.

Anyone know how to fix this?

You could skip the crafting idea and just hit it with the axe and let it drop the mats.
