[Mod] More Commands! [1.0.11] [morecommands]

[bigfoot547]

Hello! This is my first mod that I have made for minetest that I have posted!
This mod adds 22 new commands to minetest.
A full list of these commands can be seen here.
It is suggested that you use minetest 0.4.14 because I wrote the mod in that version.

BUGS:
You can use github or the comments to submit a bug report.
Pre 0.1.2: The game will crash when you use the /vanish command incorrectly.

Suggestions:
If you have an idea for a command, or any other development idea, feel free to post them in the comments!

+ Features

• Command feedback via the "enable_command_feedback" setting.
  Command feedback looks like this: [<name>: Set target's hp to 10.]
• 22 new commands to use in minetest, obviously
• Support for colored chat
• Forced command feedback via the "enable_forced_command_feedback" setting
  Forced command feedback looks like this: [<name>: Forced <target> to run command "<command> <arguments>".]
• Corresponding privileges for each command except /list
• /spawnpoint and /spawn commands now use bed spawns
• Easter Eggs!
• Many command aliases
• Use register_on_prejoinplayer for whitelist so the people off the whitelist get kicked earlier

+ Planned Features

• Relative Coordinates
• Target Selectors (@p, @r, @a)
• Target Selector Arguments
• Ideas anyone?

Mod created by: bigfoot547
With contributions made by: orwell and red-001
Contributions tweaked by: bigfoot547
With special thanks to Wuzzy for suggestions
And Jacob for play testing my mod

/back API:

• Add morecommands to depends.txt
• Before your mod teleports the player, set back_pos[name] to the player's rounded position, replacing name with the player's name.

Nice!
+1000!
Those commands look very useful for admins.

EDIT: I really like the "command_feedback"... Great work!

[D00Med]

Nice mod!

[bigfoot547]

Thank you for your support!

EDIT: I really like the "command_feedback"... Great work!

I also have "enable_forced_command_feedback" for the /sudo command that looks like this: [<name>: Forced target to run command "<command> <arguments>".]

EDIT: Added to 1st topic.

Updated to 0.1.2. Crash bug fixed.

[Wuzzy]

There are some redundant commands:

Tell a player something privately using the /tell command

We already have /msg.

Say something to the whole server using the /say command

This is called “chat”. Its when you write something without a leading slash. :P

List the players on the server using the /list command

Overlaps with /status, although /status is a bit cryptic to read. Maybe Minetest's output should be improved here.

And many of the player commands like /kill have probably implemented 1000 times in other mods, so there is potential overlap (example: playertools).

It is likely there will be more “double commands” when using this mod with another chat command registering mod. Can you somehow try to avoid this situation?

But I still think this mod can be useful for testing and on servers. Not really useful fore me however, as I will simply use /lua from luacmd and I don't moderate any server.

Thank you for the input. I am planning on replacing the /tell and /say commands with the /drop and /fnode command to spawn dropped items and falling nodes.

Here some suggestions on what to do.
These come from my private mod in which I just hack everything I need.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

--an easy way to try if and after what time the server is answering

maybe you'll find it useful.

Thank you very much for the suggestions!
I would love to feature these!

I have a question: May I use these verbatim under the LGPL v2.1+ while giving you credits?

[orwell]

yes, you may.

Enjoy!

[bigfoot547]

Does anybody use this any more?
It doesn't seem like an imperitave mod, and no one talkes about it.
Should I continue working on it?

[bigfoot547]

Does anybody have any suggestions?
*bump*

[bigfoot547]

Updated to version 1.0.11.

[hajo]

Does anybody have any suggestions?

When I want a worldmap, almost everytime I find some unexplored gaps,
or an 'uneven' border. So, I have to fly/teleport there, then make a new map.

How about some commands, like
* mapgap 0,0 - find nearest unexplored mapchunk (spiraling outward from given coordinate)
* gapfill - call mapgenerator to fill in that chunk
* mapfill 500,500 - call mapgenerator to fill in the whole map to the specified size

This probably only needs to work for a layer of +/-128 to get a nice surface-map.

Also, some commands to find map-features:
* mapfind 0,0, flat50x50 - starting at center, spiral outward to find 'flat' spots
of at least size 50x50, eg. to place a village

Possible features of interest:
* flat - terrain with max. difference in height less then 5
* cliff - terrain with height-difference > 10 on a horizontal distance of 3
* mountain - terrain-height > 60
* mountainXL - terrain-height > 100
* hill - terrain higher than 20, but lower then 60
* float - floating island
* floatland - floating island at y>1280
* water, desert, sandstone, snow, ice ... - looking for types of stones, or biomes
* waterfall
* river - with river-water
* valley
* beach - water bordered by sand
* lake - enclosed water / max. depth 10
* ocean - depth > 10
* cave - space underground
* hole - opening at the surface to a cave
* dungeon - space with mossy cobble underground
* lava
* pinetree, jungletree, acadiatree, papyrus, etc. - to find biomes by plant-type
* flowers - where is the nearest red flower?
* chest, door, torch, bed - find players place

Perhaps with an extra option to call the mapgenerator
to make more terrain until such a spot is found (or some limit is reached).

Also:
* orecount 0,0,0 coal - count number of nodes with coal-ore around position,
to get an idea how suitable a spot is for starting players
* orestat - same, but look at all types of ore
Maybe name it 'nodestat', to also look at trees, clay, etc.

Great!!!!

I think this would be a great idea, but I have a very limited knowledge when it comes to map generation and things of the sort.

Great!!!!

Thank you! I am glad you like it.
