我有一个小问题,我的arraylist中的元素没有删除.这是一个ArrayList.这是我的代码:

package net.lucrecious.armorconstruct.helpers;

import java.util.ArrayList;

import net.minecraft.block.Block;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.MathHelper;
import net.minecraft.world.World;

public class WorldHelper {

    public static void replace_coord_with_block(World world, ArrayList<int[]> coords, Block result_block){

        for (int[] c : coords){
            world.setBlock(c[0], c[1], c[2], result_block);
        }

    }

    public static ArrayList<int[]> get_blocks_in_sphere(EntityPlayer player, World world, int radius, Class<?>...block_types){

        ArrayList<int[]> coord_list = new ArrayList<int[]>();

        int r = radius;

        int i = MathHelper.floor_double(player.posX);
        int j = MathHelper.floor_double(player.posY); 
        int k = MathHelper.floor_double(player.posZ);
        for(int x = -r; x < r; x++){
            for(int y = -r; …
