Disable Lightning Fire

[Caffeinated Pinkie]

So, for a mod that I am making, I've been trying to find the simplest and cleanest way to prevent fire from spawning where lightning bolts strike. I have a few solutions already that work, the simplest of which is that I register a custom FireBlock over the vanilla one. It has a boolean in it that is set to true when EntityConstructing is called with lightning and false when it enters the world. While this value is true, fire cannot be spawned.

 

The reason why this is difficult is that the constructor for LightningBoltEntity actually spawns fire before it even enters the world. Basically, I can intercept the lightning object when it calls the Entity constructor at the start of its constructor and after it is finished constructing, by which it is already too late.

 

Do any of you have suggestions for a better method of doing this? I'm concerned about compatibility issues that may arise from overriding FireBlock.

You can create a custom implementation of LightningBoltEntity, which does not spawn fire in its constructor, and spawn that instead.

Well, the problem is that I'm trying to prevent all lightning from spawning fire, including vanilla lightning.

Hmm.

Since the fire is created before the bolt is added to the world, you could try subscribing to EntityJoinWorldEvent, check if the entity is lightning bolt, and check for fire blocks around the position of the bolt and set them to air.

This will extinguish fire in the proximity (3-5 blocks in diameter) that are not created by the lightning, but that is the closest I can think of.

Actually, that's definitely cleaner than overriding FireBlock. I already catch the lightning when it is added, so that shouldn't be hard. Thanks.
