Hi,

I have been trying to make a block sot of like the slime block from the 1.8 snapshots. I cannot get the "bouncy" effect to work, however, and I cannot figure out the obfuscated code from 1.8. Here is the class:

package com.chaosmodders.chaosbeasts.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.world.World;

import com.chaosmodders.chaosbeasts.generic.ChaosTabs;

public class BlockTrampoline extends Block
{

public BlockTrampoline() {
	super(Material.glass);
	this.setCreativeTab(ChaosTabs.tabChaosBlocks);
	this.setBlockName("trampoline");
	this.setBlockTextureName("chaosbeasts:trampoline");
	this.setHardness(0.1F);
	this.setResistance(0.1F);
	this.setHarvestLevel("sword", 10);
}

public AxisAlignedBB getCollisionBoundingBoxFromPool(World p_149668_1_, int p_149668_2_, int p_149668_3_, int p_149668_4_)
    {
        float f = 0.0625F;
        return AxisAlignedBB.getAABBPool().getAABB((double)((float)p_149668_2_ + f), (double)p_149668_3_, (double)((float)p_149668_4_ + f), (double)((float)(p_149668_2_ + 1) - f), (double)((float)(p_149668_3_ + 1) - f), (double)((float)(p_149668_4_ + 1) - f));
    }

public void onEntityCollidedWithBlock(EntityPlayerMP par1entityplayer)
{
	par1entityplayer.motionX *= -5.0D;
	par1entityplayer.motionY *= -5.0D;
	par1entityplayer.motionZ *= -5.0D;

}
}

Thanks

public void onEntityCollidedWithBlock(EntityPlayerMP par1entityplayer)

I doubt this method exist. Try the real onEntityCollidedWithBlock method.

^^ Exactly. This is why you should ALWAYS put in the @Override annotation when using vanilla methods, especially if you are not familiar with the code. It will error-check for you and let you know when you are using the incorrect method signature.

 

Also, if you want your player to bounce only when jumping on the trampoline, you might want to consider using the Block.onFallenUpon method instead.

Or better yet, always use @Override when overriding any method, Minecraft or not. As well as telling you if you did the overload wrong (mispelt name, incorrect parameters etc.) it will help you if the base class/interface changes in an update.
