Setting light level doesn't work properly

[MikeMacho]

Hello everybody!

 

I have a problem setting the light level of a block. I'm trying to create a custom lamp. When I turn it on or off the lighting is changing, but not as it's supposed to. There seem to be 2 different types of lighting. One of those is directly affected by calling

setLightLevel(float value)

(which currently is the only thing I do to change the lighting). The other one changes when I restart the game and sometimes in game, but I can't figure out what it's triggered by. For better understanding of what I'm talking about I have some screenshots:

How it's supposed to look when it's turned off:

 

And this is how it is not supposed to look when turned off but sometimes does:

 

 

How it's supposed to look when turned on:

 

 

And finally how it's not supposed to look when turned on but sometimes does:

 

 

Sorry for the long post but I think the screenshots help to make my point.

 

Thanks in advance for any help you can give me!

Thanks for your help.

I couldn't find a setState-Method (or any method to change the state) in the Block-class.

How would I trigger a state change if had set it up like you proposed?

World#setBlockState

sets the block state at the specified position in the world.

This works but it leads me to another problem. To call setBlockState I need the BlockPos-object for the block. I tried to save it into an attribute in the onBlockPlaced-Method of the Block-class but then the BlockPos-attribute is null after restarting the game.

So my question is: Is there some kind of livecycle-method in the Block-class that is called when the game starts and has the BlockPos as a parameter or is there another way to get the BlockPos-object of my block from inside the Block-class?

[Choonster]

Block

is a singleton, there is a single instance per block type shared between all blocks of that type. This means that you can't store per-position data in fields of your

Block

(or the position itself).

 

Most methods of

Block

include the

BlockPos

of the block that's currently being affected/queried (or whatever it is that the particular method does).

Would onBlockActivated suit your needs?
