我正在尝试从我的班级中生成一个自定义EntityZombie的实体。
World bukkit; // ...
CraftWorld craft = (CraftWorld)bukkit;
net.minecraft.server.v1_7_R3.World world = craft.getHandle();
Boss boss = new Boss(world);
Location spawn; // ...
boss.setLocation(spawn.getX(), spawn.getY(), spawn.getZ(), spawn.getYaw(), spawn.getPitch());
world.addEntity(boss);
public class Boss extends EntityZombie {
public Boss(World world) {
super(world);
}
// Empty right now, nothing more than the normal zombie
}
输出结果为：
与控制台无关，这是完整的崩溃报告。
