how to make creepers charged on spawn

[Crazy_sheep]

hello I am very new to minecraft forge modding a day ago when this post was made I started modding

but I have a problem I making a mod that makes the game really hard and i want to make it so every creeper that spawns will become charged

but there is no command that can make then charged

so here is my code

package ultrahardcore.ultrahardcore.events;


import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.event.entity.living.LivingSpawnEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import ultrahardcore.ultrahardcore.UltraHardCore;

@Mod.EventBusSubscriber(modid = UltraHardCore.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)

public class Events {

    @SubscribeEvent
    public void autoChargeCreeper(LivingSpawnEvent event)
    {
        // help me make the creepers charged
    }
}

@diesieben07 can you send me a basic code of a entity spawn event with the code that charges the creeper?

[Crazy_sheep]

@diesieben07 why not?

[Crazy_sheep]

@diesieben07 normaly when i see code i dont copy it and if i do copy it i will look at the code and work out how to works so plz give me some basic code on how to do that

You will copy the code, not understand it and end up here tomorrow with the next basic problem.

I don't mean to sound rude, but I disagree with that. Many times when learning something new, I'd find some example code, or code that achieves a similar effect to what i need, I'd read through it, attempt to understand and learn from it, then maybe tweak it if needed. I'm sure I'm not the only one! I understand that not everybody does that, but if they are serious about learning whatever it is, then they would.

 

That's just my opinion though.

@BlockyPenguin ok thats good to know that you dont learn of copying code or typing it manually i will note that in my brain to try to copy as less code as i can

@diesieben07 ok but what do i need to do here then 

@Mod.EventBusSubscriber()

do i need to do dist.client or dist.deticatedserver or dist.class or dist.new?

and i need to do a if statement to detect the creeper how do i do that?

and there is not setpowered or setcharged command on the CreeperEntity command

 So, you have this:

package ultrahardcore.ultrahardcore.events;


import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.event.entity.living.LivingSpawnEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import ultrahardcore.ultrahardcore.UltraHardCore;

@Mod.EventBusSubscriber(modid = UltraHardCore.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)

public class Events {

    @SubscribeEvent
    public void autoChargeCreeper(LivingSpawnEvent event)
    {
        // help me make the creepers charged
    }
}

 

First, this is not necessary, but I would suggest changing your package declaration to be something like "crazy_sheep.ultrahardcore.events".

However, as I said, this is not necessary and is just a good code practice. There are various other ways to style your package, I suggest you look into them 😄

 

Second, "value = Dist.CLIENT" is only going to be bad news. You want your events firing on both the server and client, so leave it blank. this way, forge will assume that you want your events to run on both sides.

There are other ways to register an event handler, but I won't go over those here.
 

However, to @diesieben07 I have now been looking through CreeperEntity for a while, and haven't found how to set it's powered state... 

 

EDIT: I guess nbt is a viable route

[Crazy_sheep]

@BlockyPenguin but how do i use ntb in forge?

[BlockyPenguin]

It would be something on the lines of

CompoundNBT nbt = creeper.serializeNBT();
//edit nbt here, example:
nbt.putBoolean("powered", true);
creeper.deserializeNBT(nbt);

I should imagine that would work, but I haven't tested it.

 

By the sounds of it, you don't know much about modding for forge. That's ok, we've all been there at the beginning! I suggest you read the documentation (mcforge.readthedocs.io), watch/read tutorials (Cadiboo has some great ones), and go from there. Good luck!

[Crazy_sheep]

@BlockyPenguin ok i will try i will edit this post if something is wrong else i will edit the post saying that it is working

 

EDIT:nope it does not work the 

serializeNBT();

part does not work its not a command

and where did you get the creeper command?

should it not be CreeperEntity?

Don't serialize/deserialize entities to change their field values. That's disgusting.

Oh? How would you do it then?
 

@Crazy_sheep event.getEntity will give you the Entity, which I called creeper

[Crazy_sheep]

@Draco18s it would have been helpful if you show me then how to do it

 

Edit ignore my comment

Edited October 14, 2020 by Crazy_sheep

[Crazy_sheep]

@BlockyPenguin but how would i do that in a if state ment

 

EDIT: oh i was not for a if statement sorry 😅

Edited October 14, 2020 by Crazy_sheep

[Crazy_sheep]

there is a setCreeperState() command can i do something with this to make it powered?

Let me pop my IDE open here and...

 

Well, the POWERED value and the dataManager are both private, so....

Reflection.

 

[Crazy_sheep]

@Draco18s but how do i make a reflection or how do i make the creeper powered because i still dont have the awnser

[Draco18s]

ReflectionObfuscationHelper if I remember the class's name correctly.

You call getPrivateValue and pass in the SRG name of the field you want.

 

[Crazy_sheep]

@Draco18s but what is the charged ntb called is it called powered

and if i make a Reflection do i need to do this ReflectionObfuscationHelper("powered", true)?

and when i try to do this

CreeperEntity creeper = (CreeperEntity) event.getEntity();
          if (event.getEntity() instanceof CreeperEntity) {
            creeper.ReflectionObfuscationHelper
        }

 

ReflectionObfuscationHelper is not a command

It is a class, and that's not how it works.

getPrivateValue

Store the field you got in a static final variable, then access it when needed.

[Crazy_sheep]

@poopoodice but how do I do that because I don't get it?

[Crazy_sheep]

can someone just plz send me a example code for the if statement?

[loordgek]

you need to learn java first

[Crazy_sheep]

@loordgekif I learn java I then still don't know how to do stuff in forge

and its a lot more fun to learn java with forge

Trying to explore and understand forge/minecraft concepts and code without knowing java is pure madness...trying to learn java by doing stuff that, at the beginning, makes almost no sense even to experienced Java programmers is even more madness
