Making an entity as a light source

I know for fact it works since i just tested and made sure. I dont know why i was thinking max light level was 16. Lol

Good to know. Be sure to let me know when you release your mod so I can check it out

Ok I found a bug. When I apply it to the player, when the player jumps/sprint jumps, it will leave a trail of lighted blocks behind the player. Any way to fix this?

You should remove the light for player, because they can be faster than 1block/tick.

Though it is possible, it is unlikely, and even so, they will not be moving much faster than 1 block/tick.

 

There are a couple ways to combat this, but first I am going to explain the reason behind why it is doing this.

 

Light source blocks do not update themselves when block lights around them update. couple this with the sprint jumping where you can create light blocks in a diagonal fashion, you are creating light blocks that simply aren't getting updated by the code again.

 

the ways you can combat this is to update the players last position, the problem here is that the players last position can change by 0.1 blocks, so if they go through 1054.05, 80.34, 164.56 the block that get lit will be 1054, 80, 164 then they go to 1055.01, 79, 164 just before the tick update so that is their last position according to Minecraft, and it ends up trying to update 1055, 79, 164 instead of 1054, 80, 164.

 

The other way would be to update all 26 blocks around the players location. This would probably by your best option when using light on a player.

 

I would also suggest possibly setting a "last_block_lit" variable and updating the last lit block before creating the new source, this would help with updating stray block create due to teleportation.
