[INACTIVE][MECH] Cow Paths v2 - Pave the paths where players walk [670]

Cow Paths - Pave the paths where players walk
Version: v2

Cow Paths is a bukkit plugin for simulating the natural erosion caused by player walking. The name of the plugin comes from the phrase "to pave the cow paths." As players walk around the server, Cow Paths keeps track of the number of times each block has been stepped on and erodes the world accordingly. By default, the world erosion patterns are (with step thresholds in parentheses):

Grass -(10)-> Dirt -(50)-> Gravel -(200)-> Cobblestone -(800)-> Smooth Stone
Sand -(100)-> Sandstone

Configuration
The erosion patters and step thresholds used by Cow Paths are completely configurable. All wear patterns are stored in the config.yml file under the wearPatterns key. A wear pattern is made up of a three part string containing the fromMaterial, toMaterial, and stepThreshold. A line looks like this:

Code:

- Grass Dirt 10

When defining the fromMaterial and toMaterial, you can use either a material's canonical name or ID number. Malformed wear patterns will be ignored. If two wear patterns share the same fromMaterial, only the first one will be used.

API
To access Cow Paths data in your plugins, use the following code

Code:

CowPaths cpPlugin = (CowPaths)this.getServer().getPluginManager().getPlugin("CowPaths");
CowPathsApi cpApi = cpPlugin.api;

Don't forget to add appropriate null protection.

Changelog:
Version 2

• Fixed console spamming bug
• Added API
• Added total steps metric

Version 1

• Initial Release

 

No idea how to fix it, but I can explain it.
The "snow" block is technically a block like air that you walk through not on top of, therefore you aren't standing on the snow but just walking through it so it wont register a change. When you fall on the snow you stand on it for a moment, so it registers a change there.
Never thought of that really

 

i would like to add this, but i would require multiworld support before i do.....

 

multiworld works fine, just its one configuration across all worlds. Cowpaths creates separate folder to store paths for each world.

Something has to be done about the way cowpaths stores it's data, it's now taking up more space than my world folder =(.

world folder:
649 files, 1.7GB

cowpaths:
380014 files, 1.8GB

If I compress the cowpaths folder it takes up 91MB, this tells me there is a LOT of wasted space here. Of those 380k files 296k of them are 203 bytes.

I am thinking that this doesn't have to be so precise to get the same effect, consider a chance, each time a player steps on a block there is a chance it will turn into another block. You wouldn't even need persistent storage with this method.

 

I agree with this... a percent chance would be highly preferable for me.

 

Yeah... reducing the space requirement is on my todo list. One of the reasons it takes so much space is that files can't be smaller than about 4kb on a disk, even if they take up less than 4kb of data. This is caused by minimum block sizes in the filesystem. When you compress, you are able to get rid of all the empty data.

 

I to like the chance method!

 

Hey guys, i'm getting this error:

I'm using Craftbukkit version git-Bukkit-0.0.0-706-gf53e007-b740jnks (MC: 1.5_02).

Any idea please?

 

I'll look into it tonight.

 

What I mean is on for some, off for others, or with different configurations for different worlds. I have small city worlds (limited size) with portals spaced apart in the infinite world that is my main map. I'd like to not have the city worlds degrade this way.

 

670 - inactive

 

I would love to see this maintained.

 

it isnt technically 'NOT' maintained :/

 

I'm sorry, I must have my terminology mixed up. I'd love to see it updated to the latest craftbukkit build.

 

hehe

 

Any chance of this being after 1.6 drops?

 

Maybe....after bukkit's dust settles.

 

860 seems to be a fan favorite. Any chance of updating now?

outstanding can't wait to see the release. This would go amazing my server.

 

don't expect anything till mid-july, I'm going to be quite busy

 

:-/ meh, that's a shame, but I'll still wait patiently.
