[MECH] LightSensor v0.9 - Light dependant levers [1185]

I know this sounds exactly like iLDR, but because iLDR never worked for me i wrote my own.

The basic idea is to turn redstone circuits on and off dependant on the surrounding light.
For example to close doors at night or something like that. Or what i want to do in combination with ControllerBlock fade out my torches at day and fade them in aga in at night.

How to:
Just hit a lever with a redstone torch to turn it into a LightSensor. From now on it will automatically turn on if the lightlevel of the lever is equal or less to the configured value (default: 7) and turn off again as soon as the light level increases above the configured value.
Each LightSensor can be configured with a separate value.
If you right click a LightSensor it shows you the configured value and the current lightlevel. If you right click the lever again within 2 seconds the configured value is increased by one (if 16 would be reached it steps down to 1)

Currently i check all 2 seconds the lightlevel of all registered LightSensors

LightSensor v0.9 Download

Features:
- automatically downloads sqlite.jar if needed
- each lever can get his own configuration
- lever turns on when light level is equal or less the configured value
- lever turns off when light level is above the configured value
- configurable check interval (default 2seconds)
- configurable default light sensitivity (default 7)

TODO:

Known Issues:
- Sensor attached to sand or gravel are not deleted when the block falls down and so unattaches the lever

Changelog:
Version 0.9
-Only interact with a LightSensor when the chunk is loaded

@Chris Lewis
Version 0.7 should fix both problems

 

Great thanks, testing now. If it does I will be frapsing or having on of my players fraps and upload the video of our power system using Craftbook and this plugin.

 

Thanks so much, here is a vid of our town with this plugin and craftbook... enjoy

nice one

i put that video in the top post if it's ok for you

 

Thats fine. Its nice to see the city light up, keeps the mobs at bay

 

well... it worked for me, for like 10 minutes. after that the switch started spazzing out, turned itself on and off every second and now it wont even work after reinstalling the mod. i dont even get any error messages, the only lightsensor related message in the server log is the following:
2011-04-10 12:22:39 [INFO] [LIGHTSENSOR] 0 sensors loaded
2011-04-10 12:22:39 [INFO] LightSensor version 0.7 is enabled!

to give some more information: i've connected the switch with about 20 to 30 redstone repeaters which open and close the city's gates (plugin: http://forums.bukkit.org/threads/me...easy-and-realistic-portcullises-556-670.7346/)
wanted to automate that at night so no mobs can get in.

 

i have a really annoying problem. i have it all wired up to a iron door. when it turns daytime the door opens which is how i want it but when it becomes night the door refuses to close. the redstone is off but the door wont close unless i break the circuit. any ideas?

 

I am having the same problems as some others with the switch just going back and forth repeatedly. It seems to happen when I go into the nether and back out again. Also when I hit the torch it gives me no messages like it normally does.

 

For those having issues, make sure you have craftbukkit build 670+ (current recommended build is 684). Then delete the entire LightSensor folder in your plugins folder, and delete the .jar file. Download the latest .7 version of this and then reinstall. Its possible the .db was corrupt causing this issue.
Although i have noticed that it no longer uses redstone torches to activate or give you the message? Whats up with that?

 

Hope you come back to update this.... i really want to use it for the new builds!!

this is on CB 709

 

I agree... I'm getting the same error on 711

Oh please come back developer... we love you
Recommended build 733

 

Oh no! my whole night-protection system activated by light is broken! please update quickly!! Thanks again for your great work!

 

Sorry was a bit busy the last days.
Also i won't have any time at the upcoming weekend, but i will see what i can do.

Just installing my testserver with the new recommended

 

Hoping a release soon

Thanks !

 

I love the concept, it is however not working for me. Currently running craftbukkit 740.

The lightsensor levers do not respond to a change in lightning level (using torches or daylight levels).

Something I might be doing wrong?

 

it has not been updated for a while, we are anxiously awaiting the update but he said it will be a couple of days since he is busy with life

 

I am definitely keeping tabs on this one :3

 

Hi Tiramon !

Your plugin sounds good. I have placed a request for something similar here. Do you think that you can adapt your plugin to fit the weather part ? Or I will have to look for someone else ?

 

VERY NICE plugin only please update it for the new build its a really popular thing in my server as i have made bunkers everwhere and they close at night for protection of traveling players, i really like this plugin but please update it fast : )

 

This plugin really needs to be updated. This is so useful, but it isnt working.

 

Confirmed - not working on CraftBukkit 760 - 779 and perhaps also ealier builds

 

CB 670 - inactive

 

Inactive? NOOOOOooooo

 

For anyone who still cares about this plugin I've managed to get it updated to 857 bukkit. I believe it should work with 818.

Link is here

For anyone who wants to fix it themselves later on the source is on my GitHub

This is totally unofficial until Tiramon comes back... I just was tired of all my broken light sensors hanging around so I fixed it... Figured I'd share with the community.

Enjoy.

 

Too late, I'm using Falsebook now...

 

you sir, are awesome

 

Since the latest CraftBucket commit (#937) is mentioning a bunch of renaming... I figured I should update this from using the b method to the interact method... ahead of the breakage that will probably occur next recommended. Hopefully that keeps things working... I'll be keeping an eye on it though
