[1.18.1] Connecting machines with Generator

[1HA]

Hi

(I'm trying to build my first, tech mod. I looked up several tutorial videos and their code, and tried not to use any deprecated things.)🙂

I finished making generators a few days ago, and I'm wondering how it should work(cables, etc.)

In my case, I thought that cables like IC2 cables would be better than Immersive Engineering's.

I'm not sure about how it should send&receive energy with it. I couldn't find any examples.

One way I'm thinking :

the machine(which receives the energy and consumes) tracks the connected cable. If it's connected to the generator which has energy stored, this machine works.

for a basic logic you can use BlockState Properties similar to Redstone. If you need so advanced logic you can use the EnergyCapability from Forge in combination with BlockEntities

Thx I'm working on it now

How do you plan on determining whether or not the bolded statement is true?
(by the way, the way IC2 works is that generators "push" power into cables and cables push that power into all connected adjacent blocks that accept power).

Well, I'm working on it.

First of all, thank you for your information about IC2. I had no idea about "pushing" the power from the generator. It helped me a lot.

I made cables with BlockEntity. Because I thought that the cables should check their connection in every tick. And I did almost the same as what you said.

 

During this, I got some weird error, so I just committed and pushed it to GitHub.

Error: Cannot resolve method 'of(<method reference>, net.hawon.spacesim.common.block.CopperCableBlock)'

-> from "BlockEntityInit.java" : 27

Maybe I think this error is triggered because something's missing. I think I can fix this.

*CopperCableBlockEntity.java is not a final code. It's just a test code. 

===============

By the way, what do you mean "bolded" statement?

I bolded a section in the quote of your previous post.

Your CopperCableBlockEntity doesn't have a constructor that matches the parameters being passed.

Compare:

• https://github.com/hawon10617/SpaceSim/blob/master/src/main/java/net/hawon/spacesim/common/block/entity/ExampleChestBlockEntity.java#L15
• https://github.com/hawon10617/SpaceSim/blob/master/src/main/java/net/hawon/spacesim/common/block/entity/GeneratorBlockEntity.java#L46

With:

• https://github.com/hawon10617/SpaceSim/blob/master/src/main/java/net/hawon/spacesim/common/block/entity/CopperCableBlockEntity.java#L12

I'm a bit less familiar with 1.17 and newer and how the various lambda stuff is defined, but I can compare the other block entities you have that do work with the one that doesn't: Your other two subclass and only have 2 parameters in their constructor, and generate the third for super.

Yeah, I also checked what caused the error last night(Now it's 1 pm in Seoul, Korea) quoting after you

 

I made both GeneratorBlockEntity and ExampleChestEntity with InventoryBlockEntity because they both need item handlers and they share basic logic. But in the case of CopperCableEntity, it was a kinda experiment and never needed for inv or containers. Maybe I should make a new "CableEntity" class. Then CoppperCableEntity will extend it as a super.

I'm not sure about making it with BlockEntity is right. In my case, each cable is made with BlockEntity, and as you know BlockEntity takes a lot of computing tasks, so I'm worried about whether it's not too "heavy". I know that in some parts, we have to let it go, but I'm just worried.

And... Your bolded statement. So, the cable works the same as IC2 one. It automatically attaches to the generator or any other machines if they're neighbored. Tell me if I need extra conditions for this.

Do this (top down):

G┬┐
 └┴M

where G is the generator and the M is the machine and the four others are cables.

Will your code crash, infinite loop, or transmit power?

Well, still almost nothing, 'cause I think I have to start from the scratch "again".

I think I should think more about the logic. heww...

Now I'm testing a few things with IC2 cable. 

 

About the Code Difficulty >

1. It is hard to know how to use CapabilityEnergy.
2. Especially, sendOutPower() (GeneratorBlockEntity:93).

And there are some serious logical problems... I'll do it tomorrow.

I really appreciate your help

Glad to tell u that I found a solution.

Now I'm trying to add a new custom blockstateproperty.

I hope this will work
