Hey,

I want to create a potion effect. When you walk on blocks, there is a 1% chance that it'll change into another block.

Did someone create something similar to this or can help me?

Thanks

Steps to produce:

 

Make a Potion Effect.

Make an event handler.

> Check if the potion effect is active.

> Use doubles to make it 1%.

> Get block underneath player.

> Change block to _____.

 

How do I check if the player has this potion effect and which block is underneath him?

 

EventListener:

package MyMod;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;

public class MyModEventListener
{
@SubscribeEvent
public void onTick(TickEvent.ClientTickEvent event){

}
}

 

PotionHelper:

package MyMod.handler;

import java.util.HashMap;

import net.minecraft.potion.PotionHelper;
import MyMod.items.potion.MyModPotion;

public class MyModPotionHelper extends PotionHelper {

    private static final HashMap potionRequirements = new HashMap();
public static final String effectMyMod;

static
{
	potionRequirements.put(Integer.valueOf(MyModPotion.potionMyMod.getId()), "0 & 1 & !2 &3 &3+6");
	effectMyMod = "";
}
}

 

MyModPotion:

package MyMod.items.potion;

import net.minecraft.potion.Potion;

public class MyModPotion extends Potion {

public static final MyModPotion potionMyMod= (MyModPotion) (new MyModPotion(25, false, 7589137*16).setPotionName("potion.potionMyMod"));

protected MyModPotion(int par1, boolean par2, int par3) {
	super(par1, par2, par3);

}
}

One, by not using TickEvent.ClientTickEvent as you should be checking server side.

Two, by putting code into that function.

 

(Oh, I'm sorry, did you mean to ask "how do I get a reference to the world here?" Well, if you're using the right tick type, you should be passed a reference to the player, which as an entity, contains a reference to the world)

Two, by putting code into that function.

And could you give me some hints?

I haven't ever done something like this..

Thank you!

Anyone else?

Anyone else?

 

Are there any mods that use similar potion effect? IF so, download them and decompile the code. I use JAD. But that code will contain a vanilla language, so you might missunderstand something.

No.. I don't know other mods
