基于Unity3D技术的塔防游戏虚拟人物动作控制方法

The action control method of tower defense game based on Unity3D technology

塔防游戏作为经典的休闲游戏类别之一,受到广大游戏玩家的喜爱,塔防游戏中虚拟人物的动作控制是提高游戏体验感的关键。传统的人物动作控制方法较单一,操作具有一定的局限性,动作控制的准确度不高,无法满足塔防游戏快速操作的节奏。本文提出基于Unity3D技术的塔防游戏虚拟人物动作控制方法,根据虚拟人物的行走节奏及对应帧数,进行虚拟人物行走设计;采用Kinect体感摄像头,获取人物的运动信息,识别人体动作特征,基于Unity3D技术提取人物运动数据;采用Dead Reckoning算法计算虚拟人物骨骼运动轨迹,预测人物下一步做出的动作,并进行相应控制。实验证明,该动作控制方法的准确率较高,均能达到98%以上,人物动作控制的误控率与漏控率较低,满足塔防游戏人物动作控制的需求。

As one of the classic leisure games,tower defense game is favored by lots of game players.The action control of virtual characters in tower defense game is the key to improving the sense of game experience.The traditional character action control method is relatively simple,and the operation has certain limitations,which cannot meet the fast operation rhythm of tower defense game.Based on this,the design of action control method of virtual characters in tower defense game based on Unity3D technology is proposed.According to the walking rhythm and corresponding frames of the virtual character,the walking design of the virtual character is carried out.Kinect somatosensory camera is used to obtain character motion information,human motion features is identified,and character motion data based on Unity3D technology is extracted.Dead Reckoning algorithm is used to calculate the bone motion trajectory of the virtual character,predict the next action of the character,and realize the corresponding control.Experiments show that the accuracy of this action control method reaches more than 98%,and the error control rate and missing control rate of character action control are low,which can meet the needs of character action control in tower defense game.
