[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
-deleting the lightsensor from db when the block where the sensor should be is not a lever
-Hopefully fixed the classcast of post #77

older Changelog (open) older Changelog (close)

Version 0.8
- making it working again with b1000

Version 0.7
- catching ConcurrentModificationException in LightSensorThread
- closing database connection in onDisable

Version 0.6
- removed spaming debug output
- fallback method for byId return value is null
- NullPointer Check in LightSensorPlayerListener:19

Version 0.5
- sensor check is disabled while no player is online, this fixes the reported bug on disconnect of last player
- adapted to event changes in b561

Version 0.4
- configurable check interval (default 2sec)
- configurable default value (default 7)
- fix for the not working redstone

Version 0.3
-fixed Bug with new implemented Physics
-fixed lever switching and this way attaching the lever to another wall
-sensors attached to a broken block are now deleted correctly

Version 0.2
-removed unsed command and so removed PLAYER_COMMAND

Version 0.1
First Release

Forgot to add bukkit build in the title, if someone who can change the title could please add the [440]

Sorry for the long break but i was busy with having a baby and so on
And a little desinterest in minecraft for a while

But now it is working again

 

Congratulations on the baby, and thanks for updating. I held the fort down for ya

Now, I can move along. TTFN...

 

these are not saved when the server restarts?

 

they should be i haven't changed anything at the persistence part

just tested definitly saved, even on server restart

This should normally only happen if the block at the sensor location is not a lever ...

 

Nice plugin! But could you add a motion sensor? That's what I was looking for when I found this.

 

Any change you could update this for 1060? It would be greatly appreciated.

 

i will update it this evening

What du you mean with motion sensor?
presure plates activate when you are moving over them ... should be almost the same with the correct redstone circuit

Seams to work for me on 1060 ...

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I have the exact same problem after restarting. I deleted the db and started over, and things are working fine now. However, this problem has me curious - is this plugin storing the world as well as the coordinates of the light sensor? Does this plugin support multiple worlds?

 

Hi I just started getting this error:

i'm using spout and spout essentials. I have tried deleting my db.. This error came on creating a new lightsensor

 

Yes it does

In my version i added a more comprehensable output ... but i still have no idea why this happens

 

On the latest build 1060 my lightsensors seem to turn around and you basicly see the back of the lever with the lever stuck in the wall it them completely stops working out of 3 sensors used 2 turned around and the 3rd stayed corrected but all 3 just stopped working all of them could still be adjusted for light sensitivity. Then you have to break them down and rebuild them again not sure whats causing this have loads of plugin

The bukkit Plugins then also running Mo-Creatures, ICK Slopes, FancyPack and Industrial Craft 8.55 as mods

If it's incompatibility it will take me forever to find the culprit is there anyone else experiencing same problem

 

@Conraad I have various bugs with this plugin, from it stopping working altogether to it only working when placed on certain blocks or in certain areas. I'm keeping it on my server because some of my users like it even if it is buggy, but I don't personally use it.

 

Yeah I just switch to falsebook did the same thing without bugs

 

I have no idea why they turn around and disconnect from the wall ...

Got a Version on my server which i'm currently testing
Only interacting with the lever when the chunk is loaded
deleting lever when the block where the lever should be is not a lever on init
Hopefully fixed the classcast Thrain reported in post #77
I will upload the version tomorrow

 

Version 0.9 uploaded hope it fixes some of the problems

 

Any chance you could make a side option for Time sensor? Sorta based on light but turns levers on and off depending on time of day?

 

why not will have a look for the next version

 

I love this plugin but randomly I will get the error:

2011-10-26 07:15:14 [SEVERE] Unexpected exception

As far as I can tell it's a conflict between Spout and this plugin. I am also getting the error where the levers will randomly turn around. I think that they turn around and then this happens.

 

Any chance you can make permission nodes and a option to disable this on some worlds? I've got a main world and a Vanilla world where i want to disable plugins on.

 

I also would like to see atleast 1 permission node
Just one for allow a group of users to create them

 

So the new R5 is coming out soon... Are we going to see an update? or is this already running the new code?

 

No it's not working with R5 :/
And also it seems that the jar also doesn't contain the source :/
and the author wasn't online here since the 30th sep

 

Firehunter23
It took me a literal 20 seconds to get my hand on the source.
Try a decompiler next time...

 

Hey I'm new to java ^^ so I just tried to open the file in eclipse
Thanks though

 

No problem. Remember, if source isn't available a decompiler is your next best bet.

 

Hm... I think i got it working

 

Any plan on updating?
With the new lamps, this could be epic...

 

Update to 1.2.4?
