[1.8.9] BreakEvent.block cannot be resolved or is not a field


Recommended Posts

Posted

Hi all,

 

I just started learning to mod minecraft with the help of a book (Minecraft modding with Forge). In that book there is an example which should make Diamond ore blocks explode. I have the following code:

 

package org.devoxx4kids.forge.mods;

import net.minecraft.init.Blocks;
import net.minecraftforge.event.world.BlockEvent.BreakEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class DiamondOreTrap {
@SubscribeEvent
public void explode(BreakEvent event)
{
	if(event.block != Blocks.diamond_ore)
	{
		return;
	}

	event.world.createExplosion(null, event.x, event.y, event.z, 10, true);
}
}

 

At event.block I get an error stating "block cannot be resolved or is not a field." The same goes for event.x, event.y and event.z. Am I doing something wrong here? Any help is appreciated.

In 1.8+ this was replaced with an

IBlockState

field named

state

. You must also use the getter (

getState()

) instead of accessing the field directly.

 

Thanks for the answer! Could you maybe explain it a bit more or give me link to where it is explained?

 

Also, a bit off topic, but is there any place where I can see all events? I tried googling but can't seem to find anything. (as in some kind of documentation)

Forge's documentation has an introduction to blockstates here.

Use your IDE to find the subclasses of

net.minecraftforge.fml.common.eventhandler.Event

.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Thanks! That should help.

First of all, your answer helped a lot. However I'm still having some trouble. I replaced the event.block with event.state.getBlock(). However I can't figure out how to get the coordinates of the block (what currently is event.x etc). Any chance you can help me with that?

 

EDIT: I noticed a getBlockBoundsMaxX() (also for Y, Z and min) method. Does that have anything to do with it?

Does the event have a BlockPos field? If so, the pos (position) has x, y and z getter methods.

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.

Not event state.getBlock() but event .getState().getBlock()

If I do that I get an error saying that it's undefinded for the type BlockEvent.BreakEvent. Eclipse says that the way to fix it is to cast event, but what should I cast it to?

It doesn't seem to have a direct BlockPos field. But as for the above, it says I should cast event.

The getter method didn't exist in 1.8.9, it was only in 1.9 that all event fields were encapsulated with getter methods.

BlockEvent

has a

pos

field of type

BlockPos

.

Eclipse's suggestions must always be taken with several grains of salt. They're often like offering to amputate your leg to cure you of athlete's foot.

BlockPos is a class, not a field name. Didn't you even explore the event class to see what's in it? Did you try a text-wise search for "BlockPos"? Please look at the fields and their types and their visibility.
