I'm hoping someone can help me out with this;

I need to get the light level cast upon a tile entity, as I'm trying to simulate the heat used to hatch an egg.

Is this possible? I've looked around, but haven't found anything useful.

 

getLightBrightness and getBlockLightValue both return a constant 0.0.

 

If it's not possible, what other methods could I use to simulate the heat required to hatch an egg?

Try getLight(). This is what is used in the mod spawning code so I know it returns an actual value and it uses the same parameters at getLightBrightness().

Note:

Getting the light value for the current block's location and the block is opaque will return 0 because the block is opaque.  You will need to get the light levels for the six surrounding blocks instead.

and the block is opaque will return 0 because the block is opaque.

 

That was my problem! I'll get the surrounding light values and average them out, not taking into account any 0s.

 

Thanks so much! Going to mark this as solved.
