[1.11] Get a list of all tile entities registered

Recommended Posts

I have two questions that I am stuck on. Question one: How do I get a list of all the tile entities that have been registered? Question two: Would I do this in post init to ensure all of the tiles have been registered, or would I use a different event? Any help on this is appreciated.

 

Edit: I found GameData::getTileEntityRegistry, but it's deprecated.

To address your first answer, if I'm not supposed to use the GameData method, is there an event I could subscribe to that is called when a tile entity is registered? I don't see one, but I'll look some more into it.

 

For answer 2, I have an api that can be used by other mods that containes a capability that can be attached to a tile entity. I would like to get all the tile entities to check if their classes have the capability.

 

However, on second thought, I will have to rethink that. The method I would use to check (hasCapability) isn't static. Meaning it is a per instance deal.

I haven't done much with making my own APIs for my mods, but here are some random ideas:

- You could make an empty interface that you would require mods using your API to use. In the attach capabilities event, you could check if a mod's TileEntity implements said interface and attach your capability accordingly.

- Make a custom annotation that you would require other mods' tile entities to have if they want your capability. In your mod's preinit, you can scan for all classes with said annotation via the ASMDataTable (you can see how Forge does it with @ICapabilityInject in CapabilityManager#injectCapabilities). You could populate a list with all those classes and then use it to apply your capability in the capabilities event.

- You could require all mods who want your capability to send you a IMC message with their TileEntity class name, which you would add to a list. Then in the event you can check if the TE is in the list and attach the capability if it is.

 

The first one is definitely the easiest to do (although it might not be the best), the second and third are just ramblings but might be helpful if you want to do anything more complicated in the future. I'm not really an expert, so there might be a much better way to do this.

Apart from the fact that this won't work (as you have discovered yourself)... Why? What do you need this for? If you tell us what you want to achieve, we can probably tell you how (i.e. describe what you want to do, not how).

I am creating a temperature system where some blocks give off heat. I have an api that contains a capability that mod developers can attach to their tile entities. This allows the tile entities to dynamically change their temperature. The amount of heat that reaches the player depends on how far the player is away from the tile entity.

 

Yesterday, I asked how I should get blocks within a cube around the player, and now I need to know how far I should look for tile entities. To do this, I put a maximum temperature value in the capability that is set in the constructor of the capability. Now I need to get the tile entity with the highest maximum value, if that makes any sense.

 

Long story short, getting all the tile entity classes was a stupid idea. I'm not sure how to go about this at this point. Sorry about the long post.

Heat falloff by distance, btw, is not linear. Its inverse square. 

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
