Hi,

 

How can I get a Blocks render-brightness by xyz coordinates? (e.g. The light level that is shown in the dev / F3 menu after "rl: ")

It can be any type of number format for instance: float 0.0 - 1.0, int 0-15, int 0-255. But it would be much better to have a float / int 0-255 value

 

Thanks

EDIT: A Method to get a light value at a specific double xyz coord (entity light) would be great!

In what class should I search for that method?

Found it...

I think you misunderstood me. I am not searching for the light value a Block emits, I am searching for the Light value a Block should be rendered with.

The Entitys Render Light value is computed by world.getBlockBrightness(x,y,z) (or similar name) but that method returns pretty wired values ranging from 0 to a very high number. They are later computed into the actual light values but I cant get anything to work there. I think the value represents coordinates on the light texture (skylight x blocklight y) but it does not seem like the coordinates are just bit shifted into one integer.

I'm not entirely sure either, but perhaps this could have some of the code you need...

https://github.com/BrainStone/brainstone/blob/master/main/java/brainstonemod/common/block/BlockBrainLightSensor.java

Where does an Entity get the light value to be rendeted with and how can it be calculated into a 0 - 255 value.
