[1.10.2] Event not working at all.


Bloopers

Recommended Posts

Hello. I've created a custom event with a tutorial from jabelar, that extends MouseEvent, and I've managed to get rid of all error(as the tutorial was for 1.8, there were plenty of errors) - but when I load the game it just doesn't do anything. I think it has to do with the actual registering of the event.

 

In my CommonProxy's init method, I put in

MouseEventHandler handler = new MouseEventHandler();
    	MinecraftForge.EVENT_BUS.register(handler); 

 

Is there a different way to register events in 1.10? I'm a complete noob when it comes to events, only done very basic things with them.

Hello. I've created a custom event with a tutorial from jabelar, that extends MouseEvent

 

Welp, there's your problem.  You're not supposed to extend the event classes.  You're supposed to create a single function that takes a single parameter (of any

Event

subtype) and mark it with an

@EventHandler

annotation.

 

Can you please link the tutorial you were using?

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.

Aha! Jabelar was extending the reach of a sword, not extending the mouse event class. Go back and take a closer look at the tutorial and then start over.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

I removed the part that makes it extend MouseEvent, and then tried launching again and it's the same result. Is there a reason that I should start over?

Do you have this anywhere:

 

@SubscribeEvent
public void onEvent(MouseEvent event) {
    //...
}

Yes.

And inside it is everything the event should do.

Do you know Java or was that a retorical question?

Post updated code. Are you sure you are subscribing to right MouseEvent?

Are there multiple MouseEvents?

I will post all of the code that was changed from jabelar's tutorial to fit 1.10 in a bit. I'm not on the same computer that has it right now.

MouseEvent should be donenin client proxy because the server doesnt need to know what do you have inside that method? Are you importing the correct MouseEvent?

net.minecraftforge.client.event.MouseEvent is being imported. I moved it from CommonProxy to ClientProxy, still no difference.

IExtendedReach:

package bloopers.spearmod.reach;

public interface IExtendedReach {

    public float getReach(); // default is 1.0D

}

 

And then in item classes to set the reach:

@Override
    public float getReach() 
    {
        return 15.0F;
    }

 

At 15 for testing.

Post updated code. Are you sure you are subscribing to right MouseEvent?

Are there multiple MouseEvents?

I will post all of the code that was changed from jabelar's tutorial to fit 1.10 in a bit. I'm not on the same computer that has it right now.

MouseEvent should be donenin client proxy because the server doesnt need to know what do you have inside that method? Are you importing the correct MouseEvent?

net.minecraftforge.client.event.MouseEvent is being imported. I moved it from CommonProxy to ClientProxy, still no difference.

What is button 0?

Jabelar's tutorial says it means left click, so I assume button 1 would also mean right click.

Why do you have both @SubscribeEvent and @EventHandler?

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.

Question:

Is your event not working or is your code not working?

Put a print at start of event.

2nd: Did you register event?

There are no errors in eclipse, but when I start up the game and test it out, it's as if it doesn't exist.

What is a print?

Yes, I am registering it in the FMLInitizializationEvent method in my CommonProxy. Anime fan suggested client proxy instead but that didn't change anything so I went back to CommonProxy

Registering this way:

MouseEventHandler handler = new MouseEventHandler();
    	MinecraftForge.EVENT_BUS.register(handler);

Ohh, you mean print to console? I just tested it now, apparently the init method on my CommonProxy doesn't load at all. How can I fix this?

Obviously you need to call it from your main init method in your main mod class.

Okay. Now it's in my main mod class init method. Launched the game, tried to hit a mob from far away, and the game crashed. The console tells me that it's line 65 in MouseEventHandler, which is:

SpearMod.network.sendToServer(new MessageExtendedReachAttack(mov.entityHit.getEntityId()));

    • I tried to play a mod for forge 1.20.2 and the mod didn't work, fix this please.
    • EntityRenders requires an EntityRenderProvider. This is what I have: @Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void clientSetup(FMLClientSetupEvent event) { EntityRenderers.register(HOSE.get(), new HoseEntityRenderFactory()); } private static class HoseEntityRenderFactory implements EntityRendererProvider<HoseEntity> { @Override public EntityRenderer<HoseEntity> create(Context context) { return new HoseEntityRenderer<>(context); } } } Replace HoseEntity with your own entity. If you're doing multiple try doing generics (though untested).
    • First off, I know should probably be able to debug this on my own, but this is my first mod, and I couldn't figure it out for multiple days now. What I'm trying to do, is to modify the default minecart by replacing it with a slightly different version, but I'm stuck 1 step before that, that being "cloning" the minecart as a separate Entity/Item. Here you can see a GitHub gist of all relevant files: https://gist.github.com/Kipama/cd39127e8891715a3006fa990ca7ff14 If there are files missing or access isn't working as intended, please let me know! In the Gist you can find the following files: -CustomMinecartEntity.java:        This file extends AbstractMinecart and is a clone of the vanilla minecart entity. I know I should override the minecart entity directly, but as this should work rn, I didn't change it yet. -CustomMinecartRenderer.java:  Basically vanilla MinecartRenderer with a Custom slapped on it, extends MinecraftRenderer. -ModEntities.java:                         This is where the new Entity gets added to the deferred register ENTITY_TYPES. -ModernMinecarts.java:               The main mod file. Relevant part is at the bottom, where I try to use onClientSetup to register the new Entity using EntityRenderers.register(). That last part is where my problem begins. When I try to register the new entity using EntityRenderers.register(ModEntities.CUSTOM_MINECART_ENTITY.get(), CustomMinecartRenderer::new); I get a syntax Error saying the provided and required types don't match. These are the required and provided types: ModEntities.CUSTOM_MINECART_ENTITY.get(): Required: EntityType<? extends T> Provided:EntityType<CustomMinecartEntity> CustomMinecartRenderer::new: Required: EntityRendererProvider<T> Provided:<method reference   So far I looked at 2 different Git repositories implementing custom entities, but haven't been able to figure out what I'm doing wrong. Any answers, suggestions and ridicules appreciated.
    • Yes, it is. I found out how to do it. (for Forge 1.20.1) Add this to main class constructor: // ... MinecraftForge.EVENT_BUS.<PlayerInteractEvent.EntityInteract>addListener(e -> { Player playerWhoUsed = e.getEntity(); ItemStack usedItemStack = e.getItemStack(); Entity entityThatWasClicked = e.getTarget(); if (usedItemStack.getItem() instanceof YourItem item) { // your code... e.setCancelled(true); // you can remove this if you want to continue interaction } } // ...
    • Hi there, I'm hoping to create a block that renders a fake skybox, blocking anything behind it. There are a couple of mods that already do this, but they are very outdated. One example: https://github.com/Elix-x/Skyblocks/ https://www.curseforge.com/minecraft/mc-mods/skyblocks I'm not familiar enough with rendering to be able to port it. Is there anyone who can point me in the right direction? Any help would be appreciated.
