[1.15.2] Detecting unloading of chunks that contains certain entity


Recommended Posts


I am creating a walking chest entity that has an inventory.

This entity is meant to be summoned temporarily, and should disappear (die) when the chunk it is in unloads, during which it should place down a vanilla chest block at its location.

My current idea is to subscribe to the chunk unloading event and check if my entity is in there; however, I am wondering if there are better ways (i.e. methods in LivingEntity that are triggered during unloading of the chunk it is in). There is LivingEntity#remove, but that is also fired when the entity dies, and as far as I can tell there is no way to distinguish between the two causes. 

What would be the best way to achieve this?

Some tips:


Modder Support:


1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.



Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.



The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:


1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

As far as I am aware an Entity is never told that it is being unloaded. Therefore your first approach seems to be the only way.
