How to get my item to be dropped from grass? - 1.12.2

[UM3 F0R TH3 W1N]

Hello fellow modders, I have made some seeds for my crop and I wanted to know how I can get these seeds to be dropped from grass! I know this is possible as I have seen it done before however I am clueless of how it is done. Can anyone help me doing this as I would love to have this in my mod. Many thanks in advance!

[UM3 F0R TH3 W1N]

You can add drops to other blocks by subscribing to BlockEvent.HarvestDropsEvent.

You can read up on how Forge's events work in the documentation.

so what do I need to put inside of my Event class? this is what I currently have:

 

package com.turtywurty.minecraftmadness.events.seeds;

import net.minecraftforge.event.world.BlockEvent;
import net.minecraftforge.event.world.BlockEvent.HarvestDropsEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class SeedsFromGrassEvent 
{
    @SubscribeEvent
    public void getSeedsFromGrass(HarvestDropsEvent event)
    {
        
    }
}

First of all, I doubt you own that domain name. Actually, I know you don't own it, since it's still for sale.

what domain name lol

 

[UM3 F0R TH3 W1N]

that's my package name not my domain name, I use it for all my mods but ok

Do add your drop,

that doesn't make sense anyways ^

 

[UM3 F0R TH3 W1N]

and theres no methods that it lets me use

[UM3 F0R TH3 W1N]

so I need to create a method called getDrops()?

[UM3 F0R TH3 W1N]

No. You need to call HarvestDropsEvent#getDrops and add your desired drops to it.

it doesn't let me call it

Provide code of what you have tried.

package com.turtywurty.minecraftmadness.events.seeds;

import java.util.List;

import net.minecraft.item.ItemStack;
import net.minecraftforge.event.world.BlockEvent;
import net.minecraftforge.event.world.BlockEvent.HarvestDropsEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class SeedsFromGrassEvent 
{
    public final List<ItemStack> drops;
    
    @SubscribeEvent
    public void getSeedsFromGrass(HarvestDropsEvent event)
    {
        
    }

    public List<ItemStack> getDrops() 
    { 
        return drops; 
    }
}

Just now, diesieben07 said:

That is nowhere near what I said. Why did you add a field? Why did you add a method?

You need to call a method.

I tried, it wont let me

Again: Show. What. You. Tried.

package com.turtywurty.minecraftmadness.events.seeds;

import java.util.List;

import net.minecraft.item.ItemStack;
import net.minecraftforge.event.world.BlockEvent;
import net.minecraftforge.event.world.BlockEvent.HarvestDropsEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class SeedsFromGrassEvent 
{
    @SubscribeEvent
    public void getSeedsFromGrass(HarvestDropsEvent event)
    {
        getDrops();
    }
}

but getDrops(); has an error saying that I need to create the method

[UM3 F0R TH3 W1N]

Just now, diesieben07 said:

Yes, because getDrops is a method on HarvestDropsEvent. You know Java, right?

a bit but as I said, I took a break, so ive forgotten a lot of it also: HarvestDropsEvent.getDrops(); 
doesn't work either

It is not a static method...

//but 
HarvestDropEvents h = new HarvestDropEvents();
       h.getDrops();
//doesn't work either

[UM3 F0R TH3 W1N]

nvm im stupid

 

[UM3 F0R TH3 W1N]

so, this works: 
 

package com.turtywurty.minecraftmadness.events.seeds;

import net.minecraftforge.event.world.BlockEvent.HarvestDropsEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

public class SeedsFromGrassEvent 
{
    @SubscribeEvent
    public void getSeedsFromGrass(HarvestDropsEvent event)
    {
        event.getDrops();
    }
}

so what do I do now, we're getting somewhere now lol

Add your desired item stack to the List you have now obtained.

 

This is not a chat room.

alright, thanks soo much for the help, sorry for me being a noob but I've got the hang of it now, i'm currently in the process of testing it and im hoping it works, however don't I need to call this method in my main class or something

You will need to register your event handler to the event bus, refer to the documentation linked above for more information on that.

so like this:         MinecraftForge.EVENT_BUS.register(SeedsFromGrassEvent.class);
 

[UM3 F0R TH3 W1N]

Just now, diesieben07 said:

That would be for a static event handler method, your code so far has shown a non-static one.

so this would work right:  

SeedsFromGrassEvent seedEvent = new SeedsFromGrassEvent();
MinecraftForge.EVENT_BUS.register(seedEvent);

Why don't you try it?

ok, it works but they drop every single time, is there a way I can change it to be the exact same as normal seeds?

[UM3 F0R TH3 W1N]

Tall grass has a drop-chance of 1/8 for seeds. So, generate a random number from 0 through 7 (Random#nextInt(8)) and check if it's 0. You can see this in BlockDoublePlant#getItemDropped.

ok thx so much, however it says that HarvestDropsEvent#getDropChance() is a float value not integer
