一种虚拟角色的动作切换方法、装置及存储介质
相关申请的交叉引用
本申请要求于2021年3月26日提交、申请号为202110328078.6且名称为“虚拟角色的动作切换方法和装置”的中国专利申请的优先权，其全部内容通过引用合并于此。
技术领域
本发明涉及计算机领域，尤其涉及一种虚拟角色的动作切换方法、装置及存储介质。
背景技术
目前在一些2D游戏中，游戏角色的动作都是通过帧动画来展示的，但是使用帧动画来做，在角色切换时，因为没法保证当前动作展示到的帧和下一个动作开头的帧一致，所以切换时会显得特别生硬，有特别明显的替换现象。
现有的解决方式一般会在2D动画上加上骨骼后制作相应动画，然后通过计算骨骼位置来进行融合切换。例如使用某插件执行上述操作，但是使用该插件进行动作切换时角色动作依然很僵硬，很像皮影戏和提线木偶，达不到流畅展示的效果。
针对上述的问题，目前尚未提出有效的解决方案。
发明内容
本发明提供了一种虚拟角色的动作切换方法和装置，以至少解决相关技术中虚拟角色进行动作切换时动作展示的流畅度较差的技术问题。
根据本发明实施例的第一方面，提供了一种虚拟角色的动作切换方法，应用于2D游戏，所述方法包括：在虚拟角色正在展示第一动作对应的第一帧动画的情况下，获取到所述虚拟角色的动作切换信息，所述动作切换信息用于指示将所述虚拟角色的动作从所述第一动作切换为第二动作；根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画，所述临时动画所包括的动画帧的数量少于所述部分动画所包括的动画帧的数量；以及，响应所述动作切换信息，停止展示所述第一帧动画，并依次展示所述临时动画和所述第二动作对应的第二帧动画。
在一些实施例中，根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画包括：从所述部分动画中提取关键动画帧；将所述关键动画帧按照在所述部分动画中的时间顺序连接，得到所述临时动画。
根据本发明实施例的第二方面，还提供了一种虚拟角色的动作切换装置，应用于2D游戏，所述装置包括：获取模块，用于在虚拟角色正在展示第一动作对应的第一帧动画的情况下，获取到所述虚拟角色的动作切换信息，所述动作切换信息用于指示将所述虚拟角色的动作从所述第一动作切换为第二动作；生成模块，用于根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画，所述临时动画所包括的动画帧的数量少于所述部分动画所包括的动画帧的数量；以及，展示模块，用于响应所述动作切换信息， 停止展示所述第一帧动画，并依次展示所述临时动画和所述第二动作对应的第二帧动画。
根据本发明实施例的第三方面，还提供了一种存储介质，该存储介质包括存储的程序，程序运行时执行上述的方法。
根据本发明实施例的第四方面，还提供了一种电子装置，包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序，处理器通过计算机程序执行上述的方法。
根据本发明实施例的第五方面，还提供了一种计算机程序产品，包括计算机程序/指令，所述计算机程序/指令被处理器执行时实现上述方法的步骤。
依据本发明实施例提供的虚拟角色的动作切换方法、装置及存储介质的技术方案，采用在虚拟角色正在展示第一动作对应的第一帧动画的情况下，获取到虚拟角色的动作切换信息，动作切换信息用于指示将虚拟角色的动作从第一动作切换为第二动作；根据第一帧动画中未展示的部分动画生成第一动作对应的临时动画，临时动画所包括的动画帧的数量少于部分动画所包括的动画帧的数量；响应动作切换信息，停止展示第一帧动画，并依次展示临时动画和第二动作对应的第二帧动画的方式，如果在虚拟角色正在展示第一动作对应的第一帧动画时，获取到了虚拟角色的动作切换信息来指示将虚拟角色的动作从第一动作切换为第二动作，则根据第一帧动画中未展示的部分动画生成第一动作对应的临时动画，停止播放第一帧动画后，先播放临时动画再播放第二动作的第二帧动画，达到了在虚拟角色切换动作时快速播放完原动作再播放目标动作的目的，使得在2D游戏中同一虚拟角色的不同动作切换时两个动作之间能够流畅衔接，克服了由于2D游戏虚拟角色缺少骨骼和蒙皮而无法像3D游戏虚拟角色那样流畅切换动作的问题，从而实现了提高虚拟角色进行动作切换时动作展示的流畅度的技术效果，进而解决了虚拟角色进行动作切换时动作展示的流畅度较差的技术问题。

在对本发明实施例进行介绍说明之前，首先对本发明中涉及的相关名词进行解释说明。
2D游戏：是指二维交互式动画。2D游戏中的美术资源(角色行走、角色状态、地图等等)可以是以png或jpg的图形文件渲染而成，2d游戏是没办法完成视角转换。
3D游戏：是使用空间立体计算技术实现操作的游戏。从编程实现角度来说游戏基础模型(游戏的人物，场景，基础地形)是使用三维立体模型实现的，游戏的人物角色控制是使用空间立体编程算法实现的。
虚拟角色：是在游戏应用程序中的游戏角色。游戏虚拟角色可以是人物形态，可以是动物、卡通或者其它形态，本发明实施例对此不作限定。2D游戏中的虚拟角色可以称为2D游戏虚拟角色，3D游戏中的虚拟角色可以称为3D游戏虚拟角色。
根据本发明实施例的第一方面，提供了一种虚拟角色的动作切换的方法实施例，应用于2D游戏。
在一些实施例中，上述虚拟角色的动作切换方法可以应用于如图1所示的由终端101和服务器103所构成的硬件环境中。如图1所示，服务器103通过网络与终端101进行连接，可用于为终端或终端上安装的客户端提供服务(如游戏服务、应用服务等)，可在服务器上或独立于服务器设置数据库，用于为服务器103提供数据存储服务，上述网络包括但不限于：广域网、城域网或局域网，终端101并不限定于PC、手机、平板电脑等。本发明实施例的虚拟角色的动作切换方法可以由服务器103来执行，也可以由终端101来执行，还可以是由服务器103和终端101共同执行。终端101执行本发明实施例的虚拟角色的动作切换方法也可以是由安装在其上的客户端来执行。
图2是根据本发明实施例的一种可选的虚拟角色的动作切换方法的流程图，如图2所示，该方法可以包括以下步骤：步骤S202至步骤S206。
在步骤S202，在虚拟角色正在展示第一动作对应的第一帧动画的情况下，获取到所述虚拟角色的动作切换信息，所述动作切换信息用于指示将所述虚拟角色的动作从所述第一动作切换为第二动作。
在步骤S204，根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画，所述临时动画所包括的动画帧的数量少于所述部分动画所包括的动画帧的数量。
在步骤S206，响应所述动作切换信息，停止展示所述第一帧动画，并依次展示所 述临时动画和所述第二动作对应的第二帧动画。
通过上述步骤S202至步骤S206，如果在虚拟角色正在展示第一动作对应的第一帧动画时，获取到了虚拟角色的动作切换信息来指示将虚拟角色的动作从第一动作切换为第二动作，则根据第一帧动画中未展示的部分动画生成第一动作对应的临时动画，停止播放第一帧动画后，先播放临时动画再播放第二动作的第二帧动画，达到了在虚拟角色切换动作时快速播放完原动作再播放目标动作的目的，使得在2D游戏中同一虚拟角色的不同动作切换时两个动作之间能够流畅衔接，克服了由于2D游戏虚拟角色缺少骨骼和蒙皮而无法像3D游戏虚拟角色那样流畅切换动作的问题，从而实现了提高虚拟角色进行动作切换时动作展示的流畅度的技术效果，进而解决了虚拟角色进行动作切换时动作展示的流畅度较差的技术问题。
在一些实施例中，上述虚拟角色的动作切换方法可以但不限于应用于虚拟角色的控制引擎中，比如：游戏引擎，影视动漫制作引擎，视频直播引擎等等。
在步骤S202提供的技术方案中，上述虚拟角色可以但不限于是2D游戏应用中的2D游戏虚拟角色，也可以是任何其他类型的应用所包括的2D游戏功能中的2D游戏虚拟角色，上述其他类型的应用可以但不限于包括：多媒体应用，直播应用，短视频应用，即时通信应用，金融应用，购物应用，社交应用，办公应用，教育应用等等。2D游戏虚拟角色可以但不限于为通过帧动画展示动作的虚拟角色。相比于3D游戏虚拟角色通过骨骼和蒙皮实现角色动作的方式，通过帧动画展示动作的2D游戏虚拟角色在发生动作切换时可能会出现动作不流畅的现象。
在一些实施例中，虚拟角色的动作对应的帧动画可以但不限于是通过动作软件制作的，例如：动作软件可以但不限于包括3DMAX，通过3DMAX按照3D模型动作制作规范制作2D游戏虚拟角色相应的动作。并从3DMAX中用同样标准(比如：每秒固定帧数，镜头固定在设置好的位置)将制作的动作导出为帧动画并导入引擎中使用。
可选地，在本实施例中，动作切换信息用于指示将虚拟角色的动作从第一动作切换为第二动作，动作切换信息可以但不限于是在控制虚拟角色时发出的动作切换指令，比如：玩家控制游戏角色的过程中在游戏角色执行将手臂放下的动作时玩家触发了出拳的动作，则获取到的动作切换信息用于指示将游戏角色的动作从手臂放下的动作切换为出拳的动作。
在步骤S204提供的技术方案中，部分动画是第一动作对应的第一帧动画中未展示的内容。比如：对于上述指示将游戏角色的动作从手臂放下的动作切换为出拳的动作的动作切换信息，第一动作为手臂放下的动作，其对应的部分动画可以但不限于是从获取到动作切换信息开始手臂所在的位置到手臂放下的动作结束时手臂所在的位置之间的动画。
可选地，在本实施例中，临时动画是根据第一帧动画中未展示的部分动画生成的，临时动画可以但不限于用于快速展示第一动作的剩余部分，从而在能够尽量展示完第一动作的同时，缩短展示完第一动作的第一帧动画的时间。
在一些实施例中，根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画包括：步骤S11和步骤S12。
在步骤S11，从所述部分动画中提取关键动画帧。
在步骤S12，将所述关键动画帧按照在所述部分动画中的时间顺序连接，得到所 述临时动画。
在一些实施例中，可以但不限于从第一帧动画中未展示的部分动画中提取出关键动画帧，再按照时间顺序将关键动画帧连接起来得到临时动画，从而起到缩短展示完第一动作的第一帧动画的时间的作用。
在一些实施例中，提取关键动画帧的方式可以按照时间来提取，比如：确定切换时间，再按照切换时间提取关键动画帧。或者，也可以按照动画帧数量来提取，比如：确定提取的动画帧数量，再从部分动画中提取满足该数量的关键动画帧。确定提取的动画帧数量的方式可以但不限于包括：设置预定数量，设置关键动画帧的数量在部分动画所包括的动画帧的数量中所占比例(比如：5％，7％，15％等等)，设置部分动画所包括的动画帧的数量落入不同阈值范围对应不同的关键动画帧的数量(比如：部分动画中有5至10帧，则取3帧作为关键动画帧，部分动画中有10帧以上，则取6帧作为关键动画帧)等等。
在一些实施例中，按照在部分动画中的时间顺序连接关键动画帧，从而使得临时动画中展示的第一动作的剩余部分能够连贯顺畅。
通过上述过程，从部分动画中提取出关键动画帧，再将其按时间顺序连接成临时动画，在2D游戏中同一虚拟角色切换不同动作时先展示该临时动画再展示下一个动作的帧动画，使得两个动作之间能够流畅衔接，从而克服了由于2D游戏虚拟角色缺少骨骼和蒙皮在2D游戏中同一虚拟角色的不同动作切换过程中无法像3D游戏虚拟角色那样流畅切换动作的问题，进而实现了2D游戏中同一虚拟角色切换不同动作时动作之间的流畅展示。
在一些实施例中，从所述部分动画中提取关键动画帧包括：步骤S21和步骤S22。
在步骤S21，根据切换时间确定关键帧数量，所述切换时间是从结束展示所述第一动作到开始展示所述第二动作之间的时间，所述切换时间小于所述部分动画的展示时间。
在步骤S22，从所述部分动画中提取满足所述关键帧数量的动画帧作为所述关键动画帧。
在一些实施例中，切换时间是从结束展示第一动作到开始展示第二动作之间的时间，该切换时间可以但不限于是预先设置的，比如：5毫秒，8毫秒等等。或者，切换时间也可以但不限于是根据帧动画的展示信息(分辨率等信息)自适应确定的，比如：分辨率较高则确定出较长的切换时间，分辨率较低则确定出较短的切换时间。该功能可以但不限于通过使用样本训练人工智能模型来获取。
在一些实施例中，切换时间小于部分动画的展示时间，从而体现出快速展示第一动作剩余部分的效果。切换时间还可以但不限于是根据部分动画的展示时间确定的，一方面可以通过设置切换时间相对于部分动画的展示时间的比例来确定切换时间，比如：设置切换时间是部分动画的展示时间的10％，20％，25％等等。以设置切换时间是部分动画的展示时间的20％为例，如果部分动画的展示时间为2秒，则可以确定切换时间为0.4秒。另一方面可以设置部分动画的展示时间落入不同的范围对应不同的切换时间，比如：部分动画的展示时间在0至1秒间可以不生成临时动画，1至3秒内生成0.5秒的临时动画，3秒以上生成1秒的临时动画。
在一些实施例中，关键帧数量是在切换时间内所需要展示的动画帧的数量。从部分动画中提取出满足该数量的动画帧作为关键动画帧，能够体现出第一动作快速播放的效果。
在一些实施例中，根据切换时间确定关键帧数量包括：步骤S31和步骤S32。
在步骤S31，获取所述切换时间以及所述虚拟角色的动作的帧动画帧率，所述帧动画帧率用于指示每单位时间展示动画帧的数量。
在步骤S32，将所述切换时间与所述帧动画帧率的乘积值确定为所述关键帧数量。
在一些实施例中，关键帧数量可以但不限于根据切换时间以及虚拟角色的动作的帧动画帧率来确定的，帧动画帧率用于指示每单位时间展示动画帧的数量，帧动画帧率与切换时间的乘积值可以指示在切换时间内能够展示的动画帧的数量。
在一些实施例中，上述单位时间可以但不限于是预先设定的，比如：1毫秒，10毫秒，1秒，10秒，1分，1小时等等。
在一些实施例中，从所述部分动画中提取满足所述关键帧数量的动画帧作为所述关键动画帧包括步骤S41至步骤S44之一。
在步骤S41，从所述部分动画中随机提取满足所述关键帧数量的动画帧作为所述关键动画帧。
在步骤S42，从所述部分动画中等间隔提取满足所述关键帧数量的动画帧作为所述关键动画帧。
在步骤S43，从所述部分动画中提取开始帧和结尾帧，并从除所述开始帧和所述结尾帧外的剩余帧中随机提取N-2个动画帧，得到所述关键动画帧，N为所述关键帧数量，所述关键动画帧包括所述开始帧，所述N-2个动画帧和所述结尾帧。
在步骤S44，从所述部分动画中提取开始帧和结尾帧，并从除所述开始帧和所述结尾帧外的剩余帧中等间隔提取N-2个动画帧，得到所述关键动画帧，N为所述关键帧数量，所述关键动画帧包括所述开始帧，所述N-2个动画帧和所述结尾帧。
在一些实施例中，满足关键帧数量的动画帧可以但不限于是从部分动画中随机提取的，或者，可以是等间隔提取的。
在一些实施例中，等间隔提取的方式可以但不限于是从部分动画中的第一帧开始，每隔一定间隔提取一帧，或者，也可以是跳过第一帧，每隔一定间隔提取一帧。该间隔可以但不限于是部分动画中的动画帧总数量与关键帧数量的比值，比如：部分动画中的动画帧总数量为8，关键帧数量为4，则从每两帧中提取一帧。一种提取方式可以是提取第1，3，5，7帧，另一种提取方式可以是提取第2，4，6，8帧。
在一些实施例中，可以直接将部分动画中的开始帧和结尾帧确定为关键动画帧，再从开始帧和结尾帧之间提取其余的关键动画帧。提取其余的关键动画帧的方式可以但不限于是随机提取，或者，也可以是等间隔提取。该间隔可以但不限于是开始帧和结尾帧之间的动画帧数量与关键帧数量N-2的比值，比如：部分动画中的动画帧总数量为8，关键帧数量为4，则提取出开始帧1和结尾帧8后，再从2，3，4，5，6，7中提取两帧，比如可以每三帧提取出一帧。一种提取方式可以是提取第2，5帧，另一种提取方式可以是提取第3，6帧，还有一种提取方式可以是提取第4，7帧。
通过上述过程，在同一虚拟角色切换不同动作时设置一定的切换时间来展示临时动画再展示下一个动作的帧动画，使得两个动作之间能够流畅衔接，从而克服了由于2D游戏虚拟角色缺少骨骼和蒙皮在同一虚拟角色的不同动作切换过程中无法像3D游戏虚拟角色那样流畅切换动作的问题，进而实现了同一虚拟角色切换不同动作时动作之间的流畅 展示。
在一些实施例中，根据所述第一帧动画中未展示的部分动画生成所述第一动作对应的临时动画包括：步骤S51和步骤S52。
在步骤S51，确定所述部分动画的展示时间。
在步骤S52，在所述部分动画的展示时间大于或者等于目标时间的情况下，根据所述部分动画生成所述临时动画。
在一些实施例中，可以根据部分动画的展示时间判断是否生成临时动画，如果部分动画的展示时间较长(比如大于或者等于目标时间)，则根据部分动画生成临时动画。例如：可以设置为展示时间在3秒以上的部分动画生成临时动画。
在一些实施例中，如果部分动画的展示时间较短(比如小于目标时间)，则可以不生成临时动画，直接切换为播放第二帧动画。例如：可以设置展示时间在1秒以下的部分动画则不生成临时动画，直接进行动作切换。
通过上述过程，在同一虚拟角色切换不同动作时，如果前一个动作剩余的展示时间较长，则从其剩余的部分动画中提取出临时动画在切换动作是先展示临时动画再展示下一个动作的帧动画，使得两个动作之间能够流畅衔接，从而克服了由于2D游戏虚拟角色缺少骨骼和蒙皮在同一虚拟角色的不同动作切换过程中无法像3D游戏虚拟角色那样流畅切换动作的问题，进而实现了同一虚拟角色切换不同动作时动作之间的流畅展示。
在步骤S206提供的技术方案中，停止展示第一帧动画后，先展示临时动画，再展示第二动作对应的第二帧动画，能够使得第一帧动画到第二帧动画之间平滑流畅的过度，使得虚拟角色的动作看起来更加协调顺畅。
在一些实施例中，响应所述动作切换信息，停止展示所述第一帧动画，并依次展示所述临时动画和所述第二动作对应的第二帧动画包括：步骤S61至步骤S63。
在步骤S61，响应所述动作切换信息，停止展示所述第一帧动画，所述第一帧动画的展示停止在当前帧。
在步骤S62，衔接所述当前帧展示所述临时动画。
在步骤S63，衔接所述临时动画展示所述第二帧动画。
在一些实施例中，停止展示第一帧动画是可以确定第一帧动画停止在当前帧上，再衔接该当前帧展示临时动画，接着衔接临时动画展示第二帧动画。
比如：将游戏角色的动作从手臂放下的动作切换为出拳的动作，手臂放下的动作的第一帧动画停止在手臂放下过程中的某目标位置，生成的临时动画是手臂放下动作的剩余动作的快速展示，衔接上述目标位置继续播放快速展示手臂放下动作的剩余动作的临时动画，再播放出拳的动作的第二帧动画。
通过上述过程，在同一虚拟角色切换不同动作时，停止展示前一个动作的帧动画后，接着先展示生成的临时动画再展示下一个动作的帧动画，使得两个动作之间能够流畅衔接，从而克服了由于2D游戏虚拟角色缺少骨骼和蒙皮在同一虚拟角色的不同动作切换过程中无法像3D游戏虚拟角色那样流畅切换动作的问题，进而实现了同一虚拟角色切换不同动作时动作之间的流畅展示。
在一些实施例中，衔接所述临时动画展示所述第二帧动画包括：步骤S71和步骤S72。
在步骤S71，衔接所述临时动画展示所述第二帧动画中所包括的切换动画，所述切换动画用于展示所述第一动作和所述第二动作之间的切换动作。
在步骤S72，衔接所述切换动画展示所述第二帧动画中所包括的动作动画，所述动作动画用于展示所述第二动作。
在一些实施例中，第二动作对应的第二帧动画可以但不限于包括切换动画和动作动画，切换动画用于展示第一动作和第二动作之间的切换动作，动作动画用于展示第二动作。
在一些实施例中，不同动作之间的切换动作可以不同，切换动作可以是在制作动作动画时制作出来的，可以通过上述动作软件3DMAX制作。
比如：对于上述出拳的动作，从手臂放下的动作切换为出拳的动作时，两个动作之间的切换动作可以是抬起手臂的动作，从伸手的动作切换为出拳的动作时，两个动作之间的切换动作可以是收回手臂的动作等等。
将游戏角色的动作从手臂放下的动作切换为出拳的动作，手臂放下的动作的第一帧动画停止在手臂放下过程中的某目标位置，生成的临时动画是手臂放下动作的剩余动作的快速展示，衔接上述目标位置继续播放快速展示手臂放下动作的剩余动作的临时动画，再播放抬起手臂的动作，接着再播放出拳的动作。
通过上述过程，在同一虚拟角色切换不同动作时，停止展示前一个动作的帧动画后，接着先展示生成的临时动画，然后展示两个动作之间的切换动作的切换动画，再展示下一个动作的动作动画，使得两个动作之间能够流畅衔接，从而克服了由于2D游戏虚拟角色缺少骨骼和蒙皮在同一虚拟角色的不同动作切换过程中无法像3D游戏虚拟角色那样流畅切换动作的问题，进而实现了同一虚拟角色切换不同动作时动作之间的流畅展示。
本发明还提供了一种可选实施例，该可选实施例提供了一种控制2D游戏虚拟角色切换动作的过程，图3是根据本发明可选实施例的一种控制2D游戏虚拟角色切换动作的过程的示意图，如图3所示，该过程包括：步骤S301至步骤S306。
在步骤S301，利用3DMAX等动作软件按照3D模型动作制作规范制作2D游戏虚拟角色相应动作和每两个动作之间的切换动作。
在步骤S302，从3DMAX中将动作导出为帧动画并导入游戏引擎。
在步骤S303，在引擎中通过以下帧动画切换逻辑来实现动作切换的控制：首先在检测到动作切换时。确定当前帧动画(相当于上述第一帧动画)播放到了第几帧，以及当前帧动画还剩多少帧没播放完(即上述部分动画)，并确定切换时间。
在步骤S304，确定出在切换时间内，游戏角色能播放N帧帧动画。
在步骤S305，从当前帧动画剩余没播放完的动画中提取开始帧和结尾帧，再从余下没播完的帧里等间隔取出N-2帧帧动画合成新的帧动画(即上述临时动画)。
在步骤S306，切换播放该临时动画，等播放完临时动画后再直接切到本来应该播放的两个动作之间的切换动画，再播放切换到的动作的动画(即上述第二帧动画)。
通过上述过程，对于动画制作人员无任何学习成本，还是利用自己熟悉的软件制作3D动画即可；同时比起Spine等插件，无关节感，不像木偶戏那么僵硬，同时比起帧动画传统直接切换方式显得更加流畅自然。对游戏玩家来说，增加了游戏角色动作流畅度，使得观感更好。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
