API 处理实现

将 API 处理接口 HandleApiService 实现为 HandleApiImpl 类，并在其中编写具体的处理逻辑。

Broadcast 实现示例

public class HandleApiImpl implements HandleApiService { // 实现 API 处理接口
    /**
     * 广播消息
     *
     * @param jsonElement 消息体
     */
    @Override
    public void handleBroadcastMessage(JsonElement jsonElement) {
        // 使用工具类将 JSON 前缀元素解析为文本组件
        ITextComponent prefixed = ForgeTool.parseJsonToTextWrapped(GlobalContext.getMessagePrefixJsonObject());
        // 使用工具类将 JSON 聊天信息参数解析为文本组件
        ITextComponent message = ForgeTool.parseJsonToTextWrapped(jsonElement);

        // 如果消息和前缀均不为空，则向所有在线玩家发送消息
        if (message != null && prefixed != null) {
            for (EntityPlayerMP serverPlayer : minecraftServer.getPlayerList().getPlayers()) {
                serverPlayer.sendMessage(prefixed.appendSibling(message));
            }
        }
    }

    // 其他方法省略...
}
