What i want to do:

I want to make a mod, where the player can jump much higher then normal height.

The height should be 15 times higher then normal height.

This function will only be available if my position is on an slime_block.

I no this mod may be really strange, but why not?

 

The code

package jattys.mods.devox4kids;

 

import net.minecraft.block.Block;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.init.Blocks;

import net.minecraftforge.event.entity.living.LivingEvent.LivingJumpEvent;

import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;

 

public class SuperJump {

   

@SubscribeEvent

public void BouncySlimeBlock(LivingJumpEvent event){

if(!(event.entity instanceof EntityPlayer)) {

return;

}

 

if(event.entity.worldObj.(where i get an error)getBlock(

((int) Math.floor(event.entity.posX)),

((int) Math.floor(event.entity.posY)) - 2,

((int) Math.floor(event.entity.posZ))) != Blocks.slime_block){

return;

}

 

event.entity.motionY *= 15;

}

}

 

The error

The method getBlock(int, int, int) is undefined for the type World.

 

What can i actually do?

sorry forgot to tell you i am modding in 1.8

World#getBlock(int,int,int)

was replaced by

World#getBlockState(BlockPos)

in 1.8, which returns an

IBlockState

.

IBlockState#getBlock

will return the

Block

of the

IBlockState

.

 

You can use

Entity#getPosition

to get an

Entity

's position as a

BlockPos

and

BlockPos#down(int)

to subtract an amount from the y coordinate.
