[1.14.4] Modifying Vanilla Content

[MineModder2000]

Instead of adding in things, I want to know how to remove them.

 

Examples : default mobs and the ability to punch blocks to acquire them.

This depends on what you want to do.

 

You can cancel EntityJoinWorldEvent.

 

You mean you want to disable block drops? Please elaborate.

Okay thanks I will try that. I mean the punch shouldn't even break blocks.

Use the PlayerEvent.BreakSpeed event and if the player isn't holding an item set the break speed to 0.

BreakSpeed isn't a method...

I was just reading that before you posted. Thanks, I'll study it and then post any more questions here.

I figured out events and what not, but I am having trouble doing an if statement check for whether the player is holding an item, 

 

   @SubscribeEvent
    public void breakSpeed(BreakSpeed event) {
        
        event.setNewSpeed(0);
    }

 

I don't how to check for that exactly.

event.getEntityPlayer().getHeldItem(Hand.MAIN_HAND).getItem() == SOME_ITEM_FIELD

It warns me :

 The method getEntityPlayer() from the type PlayerEvent is deprecated

1.14.4. Also getItem() method looks like this :

 

return this.isEmpty || this.delegate == null ? Items.AIR : this.delegate.get();

 

isEmpty would be useful of course, but's its a private boolean variable....

Instead use ItemStack.isEmpty(event.getEntityPlayer.getHeldItem(Hand.MAIN_HAND))

Quote

The method isEmpty() in the type ItemStack is not applicable for the arguments (ItemStack)

 

That method is empty and doesn't accept parameters. Also it says not to make a reference to it since its not static....

Oops my bad. Use ItemStack#isEmpty so

event.getEntityPlayer().getHeldItem(Hand.MAIN_HAND).isEmpty()

Works like a charm. But with this I can still break blocks if I have a flower or anything else in the player's hand. What I intend is to only be able to break blocks with the correct tool (shovel for dirt, axe for wood, etc.)

Then you'll want to check if they have a tool that can break the block.

Exactly how are you supposed to get tools if you can't punch trees? Please explain.

Does it really matter? Why would they make a mod where you can't progress?

Haha, I have ideas. Such as gather-able sticks and stone generating through the world that will make your first set of tools.

Of course, but I'm not sure how to do that.

Well you know how to get the Item and the ItemStack the player is holding. You can check. Look at the tool Items in Items.class. They have methods you might be able to use. Or you can use instanceof checks.

Right but how about checking against the block that is aimed at?

event.getState() will give you the BlockState

Thanks making some progress. I'll see how far I can get, I should be able to figure this out.

For future reference, an instance of Event will have all the relevant information stored in it. You can use your IDE to look at all the information stored in it.
