[1.10.2] Event not working at all.


Bloopers
 Share

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

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()));
