Make a block with a lightlevel >15

[Jacky2611]

Guess the title says everything.

I want to have a sunlight generator with a range of around 80 blocks.

Is something like this possible? And where can i find the sun/sky class?

Not without being a coremod. Light value is limited to 16 values by the save format, so you'd have to change a lot of stuff.

But you can do something else, somewhat like the Thaumcraft Arcane Lamp. That lamp places invisible block that act like air blocks, but they emit light.

Sounds like a good idea. Isn't it possible to make something like the sky/sun does? what i basically want to create is a sun-block...

Sun light doesnt exceed 15. It just all cells with direct view of the sky get this 15 value if i recsll correctly. If this is what you want you could find where in the lighting code this happens you can maybe make your block count as the sky. Pretty sure will need to be a core mod todo that.

The problem is that i can't find the sky...

Is this 1.7 lightlevel can be any float it seems in 1.7

That function exists in 1.6 as well.  It's just another way to specify 0-15.

A very quick look in my IDE showed my World.computeLightValue, which when computing for sky lighting immediately checks canBlockSeeTheSky...

 

So if you actually want your block to behave like sky (so essentially light an infinite distance downwards through air) id mod that function to call a custom canBlockSeeTheSky type function that also returns true if when searching upwards it finds your block.

[Draco18s]

canBlockSeeTheSky just does a loop check looking for not-air blocks* until it hits the world ceiling.

If it finds one, it returns false.  If it doesn't, it returns true.

 

*Pretty sure it doesn't do fancy things like looking for entirely transparent blocks.  Been a while since I looked at it.
