How do i make my entity emmit light?

[Drachenbauer]

Hello

My new Entity has got an antenna with a glowing tip on it´s head (like an angler-fish).

How can i make it emmit it´s own light, that moves with it?

Light only comes from blocks.

So you can either use a library mod that enables you to do this (DynamicLights/OptiFine) or write your own implementation. The common way to do this without a library is to place and destroy invisible blocks that emit light. This doesn’t work underwater though and is pretty bad for performance and has other issues like how to remove the block.

That’s up to you. As I said, I suggest using OptiFine/DynamicLights as a dependency.
