具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
首先，对本申请实施例中涉及的若干个名词进行简要介绍。
虚拟环境：是应用程序在终端上运行时显示(或提供)的虚拟环境。该虚拟环境可以是对真实世界的仿真环境，也可以是半仿真半虚构的三维环境，还可以是纯虚构的三维环境。虚拟环境可以是二维虚拟环境、2.5维虚拟环境和三维虚拟环境中的任意一种，下述实施例以虚拟环境是三维虚拟环境来举例说明，但对此不加以限定。
虚拟对象：是指在虚拟环境中的可活动对象。该可活动对象可以是虚拟人物、虚拟动物、动漫人物中的至少一种。可选地，当虚拟环境为三维虚拟环境时，虚拟对象是基于动画骨骼技术创建的三维立体模型。每个虚拟对象在三维虚拟环境中具有自身的形状和体积，占据三维虚拟环境中的一部分空间。
虚拟摇杆：是指在虚拟环境中，用于控制虚拟对象在虚拟环境中移动的控件。用户通过终端屏幕上的触控操作，可以控制该虚拟摇杆的移动，进一步控制虚拟对象进行移动。可选地，在本申请实施例中，该虚拟摇杆可以是圆形、 在一些其它实施例中，该虚拟摇杆还可以是三角形、正方形、六边形、八边形等等，也可以是其它不规则图形，本申请实施例对此不作限定。上述虚拟摇杆在可移动区域内移动。可选地，该可移动区域的形状可以与虚拟摇杆的形状相同或者不同。例如，虚拟摇杆为圆形，可移动区域也为圆形，且两者为同心圆；又例如，虚拟摇杆为六边形，可移动区域为八边形，且两者中心重合。
本申请提供的虚拟对象的移动控制方法可以应用于的终端中，该终端可以是膝上型便携计算机、手机、平板电脑、电子书阅读器、电子游戏机、动态影像专家压缩标准音频层面4(Moving Picture Experts Group Audio Layer IV，MP4)播放器等等。
终端中安装基于虚拟环境的应用程序。该虚拟环境中包括虚拟对象。可选地，应用程序支持三维虚拟环境的应用程序。该应用程序可以是虚拟现实应用程序、三维地图程序、军事仿真程序、游戏程序，如TPS游戏、第一人称射击(First Person Shooting，FPS)游戏、多人在线战术竞技(Multiplayer Online Battle Arena，MOBA)游戏、多人枪战类生存游戏中的任意一种。可选地，该应用程序可以是单机版的应用程序，比如单机版的3D游戏程序；也可以是网络联机版的应用程序。
在传统方案中，用户手指在屏幕上的触控点只能在虚拟摇杆的可移动区域内移动，局限性比较强。为了解决传统方案存在的问题，相关技术提供了一种方法，即当触控点在虚拟摇杆的可移动区域之外时，虚拟摇杆仍然保持启动状态。在这种情况下，获取触控点的位置与可移动区域的中心之间的连线，将该连线与可移动区域的边缘的交点坐标，确定为虚拟摇杆的位置。
在上述相关技术中，当位于虚拟摇杆的可移动区域之外的触控点反向移动时，在触控点移动至可移动区域的边缘的过程中，虚拟摇杆的位置保持不变。触控点移动至可移动区域的边缘内时，虚拟摇杆才开始反向移动。从而，导致用户的操作效率低。
本申请提供的技术方案，在启动虚拟摇杆后，根据触控点的位置变化量，调整虚拟摇杆在可移动区域中的位置，且当触控点在有效触控范围内移动时，虚拟摇杆的位置与触控点的位置实时同步变化。相比于相关技术中，当触控点位于虚拟摇杆的可移动区域之外时，在虚拟摇杆移动同样距离的情况下，本申请中触控点移动的距离更小，提高了用户的操作效率。
下面，将通过几个实施例对本申请技术方案进行介绍说明。
请参考图1，其示出了本申请一个实施例提供的虚拟对象的移动控制方法的流程图。在本实施例中，主要以该方法应用于上文介绍的终端中来举例说明。该方法可以包括如下几个步骤(101-104)：
步骤101，显示目标应用程序的目标视角画面，在目标视角画面上叠加显示虚拟摇杆和虚拟摇杆的可移动区域。
上述目标应用程序可以是基于虚拟环境的应用程序。可选地，该应用程序可以是虚拟现实应用程序、三维地图应用程序、军事仿真程序、游戏应用程序， 该游戏应用程序可以是TPS游戏、FPS游戏、MOBA游戏等中的至少一种。
终端运行该目标应用程序，以显示目标视角画面。上述目标视角画面是以虚拟对象的目标视角对虚拟环境进行观察所得到的画面。可选地，上述目标视角是采用虚拟对象的第一人称视角观察虚拟环境的视角，或者，上述目标视角是采用虚拟对象的第三人称视角观察虚拟环境的视角。
上述目标视角画面中可以叠加显示虚拟摇杆和该虚拟摇杆的可移动区域。另外，终端还可以显示虚拟环境中包括的至少一个虚拟对象。
上述虚拟摇杆用于在虚拟环境中控制虚拟对象进行移动。其它关于虚拟摇杆的介绍请参考上文的名词简要介绍中，此处不再赘述。
上述虚拟摇杆的可移动区域用于限制虚拟摇杆的移动范围，使虚拟摇杆只能在该可移动区域内移动。可选地，在初始状态下，虚拟摇杆位于可移动区域的中心。
可选地，上述可移动区域的形状可以与虚拟摇杆的形状相同或者不同。例如，虚拟摇杆为圆形，可移动区域也为圆形，且两者为同心圆；又例如，虚拟摇杆为六边形，可移动区域为八边形，且两者中心重合。
步骤102，当获取到对应于虚拟摇杆的触发操作时，启动虚拟摇杆。
终端可以检测是否接收到用户作用于屏幕上的用于启动虚拟摇杆的触发操作，当终端获取到对应于虚拟摇杆的触发操作时，启动虚拟摇杆。
可选地，该触发操作可以是按压操作、单击操作、滑动操作等等，本申请实施例对此不作限定。
可选地，终端可以通过触摸屏检测该触发操作的位置，即用户手指在屏幕上的触控点的位置，并判断该触控点是否在虚拟摇杆的触发范围内，当在虚拟摇杆的触发范围内时，根据该触发操作启动虚拟摇杆，当不在虚拟摇杆的触发范围内时，终端不响应该触发操作。上述虚拟摇杆的触发范围可以是虚拟摇杆的可移动区域，也可以是大于可移动区域的一块区域，本申请实施例对此不作限定。
另外，当终端检测到作用于屏幕上的触控操作消失时，关闭虚拟摇杆。
步骤103，在虚拟摇杆处于启动状态下，根据触控点的位置变化量，调整虚拟摇杆在可移动区域中的位置，其中，当触控点在有效触控范围内移动时，虚拟摇杆的位置与触控点的位置实时同步变化，有效触控范围包含且大于可移动区域。
若终端检测到作用于屏幕上的连续的触控操作，则确认该虚拟摇杆处于启动状态。在启动状态下，用户在终端屏幕上滑动使触控点位置发生改变，对应地，终端可以确定两个时刻之间该触控点的位置变化量，进一步，可以根据该触控点的位置变化量来调整虚拟摇杆在可移动区域中的位置。
在本申请实施例中，当触控点在有效触控范围内移动时，虚拟摇杆的位置与触控点的位置实时同步变化，有效触控范围包含且大于可移动区域。可选地，该有效触控范围可以是终端的整个屏幕，也可以是终端的部分屏幕区域，本申请实施例对此不作限定。在触控点的有效触控范围内移动时，当触控点的位置 发生改变的同时，虚拟摇杆的位置也发生改变。例如，当触控点的位置发生反向的同时，虚拟摇杆的位置也反向，两者实时同步变化。
需要说明的是，当触控点在可移动区域内移动时，虚拟摇杆的位置即为触控点的位置。当触控点在有效触控范围内但在可移动区域外移动时，终端根据触控点的位置，通过一定的运算得到虚拟摇杆的位置。
步骤104，根据虚拟摇杆的位置控制虚拟对象进行移动。
在确定虚拟摇杆的位置之后，终端可以根据虚拟摇杆的位置，如方向和距离，控制虚拟对象移动。
在一些其它实施例中，根据虚拟摇杆的位置还可以生成不同的标记，如警戒标记、物资标记、进攻标记、防御标记等等，其中，警戒标记用于提示虚拟对象进行警戒，或者，提示虚拟对象对标记的位置进行警戒；物资标记用于提示虚拟对象在标记的位置有物资；进攻标记用于提示虚拟对象开始进攻，或者，提示虚拟对象向标记的位置进攻；防御标记用于提示虚拟对象进行防御。
结合参考图2，其示例性示出了一种虚拟对象的移动控制方法的示意图。以虚拟摇杆和虚拟摇杆的可移动区域均为圆形，触控点反向移动为例。如图2所示，在初始状态下，虚拟摇杆10位于可移动区域20的中心。当终端获取到对应于虚拟摇杆10的触发操作时，启动虚拟摇杆10；当触控点30在可移动区域20内移动时，触控点30的位置与虚拟摇杆10的位置相同；当触控点30在可移动区域20之外移动时时，虚拟摇杆10在可移动区域20的边缘上移动；当触控点30开始反向移动的同时，位于可移动区域20的边缘上的虚拟摇杆10也开始反向移动，两者实时同步。
综上所述，在本申请实施例提供的技术方案中，在启动虚拟摇杆后，根据触控点的位置变化量，调整虚拟摇杆在可移动区域中的位置，且当触控点在有效触控范围内移动时，虚拟摇杆的位置与触控点的位置实时同步变化。相比于相关技术中，当触控点位于虚拟摇杆的可移动区域之外时，在虚拟摇杆移动同样距离的情况下，本申请中触控点移动的距离更小，提高了用户的操作效率。
请参考图3，其示出了本申请另一个实施例提供的虚拟对象的移动控制方法的流程图。在本实施例中，主要以该方法应用于上文介绍的终端中来举例说明。该方法可以包括如下几个步骤：
步骤301，显示目标应用程序的目标视角画面，在目标视角画面上叠加显示虚拟摇杆和虚拟摇杆的可移动区域。
可选地，在初始状态下，虚拟摇杆位于可移动区域的中心。
本步骤与图1实施例中的步骤101相同或类似，此处不再赘述。
步骤302，当获取到对应于虚拟摇杆的触发操作时，启动虚拟摇杆。
本步骤与图1实施例中的步骤102相同或类似，此处不再赘述。
可选地，终端可以实时判断虚拟摇杆是否仍然启动，当判断为是时，终端继续保持虚拟摇杆处于启动状态；当判断为否时，终端关闭虚拟摇杆。
在虚拟摇杆处于启动状态下，执行下述步骤303。
步骤303，获取触控点从第一时刻到第二时刻的位置变化量。
终端可以实时获取触控点的位置，从而可以得到触控点在第一时刻的位置和第二时刻的位置，进一步得到触控点从第一时刻到第二时刻的位置变化量。该位置变化量为包括方向和距离的矢量。可选地，上述第一时刻和第二时刻之间间隔目标时长，本申请实施例中对目标时长不作限定。
示例性地，触控点在第一时刻的位置可以表示为(X1，Y1)，触控点在第二时刻的位置可以表示为(X2，Y2)，则触控点从第一时刻到第二时刻的位置变化量，即横坐标的变化量与纵坐标的变化量，可以表示为(X0，Y0)＝(X2-X1，Y2-Y1)。
步骤304，根据位置变化量和虚拟摇杆在第一时刻的位置，计算虚拟摇杆在第二时刻的预计位置。
终端还可以获取虚拟摇杆在第一时刻的位置，当触控点从第一时刻的位置移动到第二时刻的位置时，虚拟摇杆的位置也发生改变。假设当虚拟摇杆不受可移动区域的限制时，该虚拟摇杆可以实现与触控点相同的位置变化量，此时即得到第二时刻的预计位置。
示例性地，虚拟摇杆在第一时刻的位置可以表示为(x1，y1)，触控点的位置变化量可以表示为(X0，Y0)，则虚拟摇杆在第二时刻的预计位置可以表示为(A，B)＝(x1+X0，y1+Y0)。可选地，若第一时刻为初始状态，则虚拟摇杆在第一时刻的位置可以表示为(0，0)。
可选地，终端可以判断虚拟摇杆在第二时刻的预计位置时，是否位于可移动区域之内，当位于可移动区域之外时，执行下述步骤305；当位于可移动区域之内时，执行下述步骤306。
示例性地，终端可以计算该虚拟摇杆在第二时刻的预计位置，相对于可移动区域中心(即原点)的距离，若该距离大于可移动区域，则认为该预计位置位于可移动区域之外；若该距离小于或等于可移动区域，则认为该预计位置位于可移动区域之内。
以可移动区域为半径为R的圆形为例，虚拟摇杆在第二时刻的预计位置可以表示为(A，B)，则该预计位置相对于可移动区域中心的距离可以表示为
Figure PCTCN2020092342-appb-000001
当r≤R时，认为该预计位置位于可移动区域之内；当r>R时，认为该预计位置位于可移动区域之外。
步骤305，若预计位置位于可移动区域之外，则根据预计位置和可移动区域，计算虚拟摇杆在第二时刻的实际位置。
实际上，由于虚拟摇杆只能在可移动区域内移动，因此，当预计位置位于可移动区域之外时，需要将上述预计位置映射到其实际位置上。
可选地，上述步骤305可以包括下述两个步骤：
(1)计算预计位置与可移动区域的中心之间的连线，与可移动区域的边缘的交点坐标；
(2)将该交点坐标确定为虚拟摇杆在第二时刻的实际位置。
示例性地，结合参考图4，其示例性示出了计算虚拟摇杆第二时刻的实际位置的示意图。以可移动区域和虚拟摇杆为圆形为例，且可移动区域的半径为R， 其中，触控点在第一时刻的位置为M(X1，Y1)，触控点在第二时刻的位置为N(X2，Y2)，虚拟摇杆在第一时刻的位置为P(x1，y1)，虚拟摇杆在第二时刻的预计位置为Q1(A，B)，虚拟摇杆在第二时刻的实际位置为Q2(x2，y2)。根据M(X1，Y1)和N(X2，Y2)，可以得到触控点的位置变化量，即X轴变化了X0＝X2-X1，Y轴变化了Y0＝Y2-Y1；虚拟摇杆在第二时刻的预计位置Q1(A，B)，其中，A＝x1+X0，B＝y1+Y0；对应地，预计位置Q1(A，B)与可移动区域的中心O(0,0)之间的连线，与可移动区域的边缘的交点坐标为Q2(x2，y2)，其中，x2＝R*SINβ，y2＝R*COSβ，又根据几何原理，β＝α＝arctan(A/B)，即x2＝R*SIN(arctan(A/B))，y2＝R*COS(arctan(A/B))；进一步，将该交点坐标确定Q2(x2，y2)确定为虚拟摇杆在第二时刻的实际位置。
步骤306，若预计位置位于可移动区域之内，则将预计位置确定为虚拟摇杆在第二时刻的实际位置。
当预计位置位于可移动区域之内时，终端直接将该预计位置确定为虚拟摇杆在第二时刻的实际位置。
步骤307，根据虚拟摇杆的位置，计算虚拟摇杆相对于可移动区域的中心的方向和距离。
在获取到上述虚拟摇杆第二时刻的实际位置后，终端可以计算虚拟摇杆相对于可移动区域的中心的方向和距离。
步骤308，根据方向和距离，确定虚拟对象的移动方向和移动速度。
进一步，终端根据该虚拟摇杆的方向和距离，确定虚拟对象的移动方向和移动速度。其中，虚拟摇杆的方向可以映射为虚拟对象的移动方向，虚拟摇杆的距离可以映射为虚拟对象的移动速度，当该距离越大时，表示虚拟对象的移动速度越快。
步骤309，根据移动方向和移动速度，控制虚拟对象进行移动。
在获取到上述移动方向和移动速度之后，控制虚拟对象在虚拟环境中进行移动，如行走、奔跑、跳跃等。
综上所述，在本申请实施例提供的技术方案中，通过判断虚拟摇杆的预计位置是否在可移动区域内，并当预计位置位于可移动区域之外时，将预计位置与可移动区域的中心之间的连线，与可移动区域的边缘的交点坐标，确定为虚拟摇杆在第二时刻的实际位置。本申请实施例提供的技术方案，在完成该项操作时触控点移动距离更小，即用户手指滑动距离更小，进一步提高了用户的操作效率。
下面，结合参考图5，其示例性示出了虚拟对象的移动控制方法的流程图。
步骤501，获取对应于虚拟摇杆的触发操作，启动虚拟摇杆。
步骤502，判断虚拟摇杆是否仍然处于启动状态。
若虚拟摇杆不是处于启动状态，执行下述步骤503；若虚拟摇杆仍然处于启动状态，则执行下述步骤504。
步骤503，关闭虚拟摇杆。
步骤504，实时获取触控点的位置坐标(X，Y)。
步骤505，获取触控点从第一时刻到第二时刻的位置变化量(X0，Y0)。
步骤506，根据位置变化量(X0，Y0)和虚拟摇杆在第一时刻的坐标(x1，y1)，计算虚拟摇杆在第二时刻的预计位置横纵坐标(A，B)。
步骤507，计算虚拟摇杆在第二时刻的预计位置横纵坐标(A，B)距离可移动区域的中心(0，0)的距离r。
步骤508，判断上述距离r是否大于可移动区域的半径R。
当r<＝R时，执行下述步骤509；当r>R时，执行下述步骤510。
步骤509，将预计位置(A，B)确定为虚拟摇杆在第二时刻的实际位置。
步骤510，将预计位置与可移动区域的中心之间的连线，与可移动区域的边缘的交点坐标，确定508为虚拟摇杆在第二时刻的实际位置。
上述交点坐标(x2，y2)中，x2＝R*SIN(arctan(A/B))，y2＝R*COS(arctan(A/B))。
步骤511，根据虚拟摇杆的位置，计算虚拟摇杆相对于可移动区域的中心的方向和距离。
步骤512，根据方向和距离，确定虚拟对象的移动方向和移动速度。
步骤513，根据移动方向和移动速度，控制虚拟对象进行移动。
下面，将本申请提供的技术方案与相关技术提供的技术方案进行对比，进一步阐述本本申请提供的技术方案的有益效果。
结合参考图6，其示例性示出了触控点反向移动的示意图。其中，图6中的(a)部分、(b)部分和(c)部分为相关技术提供的技术方案；图6中的(d)部分和(e)部分为本申请提供的技术方案。如图6中的(a)部分、(b)部分和(c)部分所示，当位于虚拟摇杆10的可移动区域20之外的触控点30反向移动时，在触控点30移动至可移动区域20的边缘的过程中，虚拟摇杆10的位置保持不变；触控点30移动至可移动区域20的边缘内时，虚拟摇杆10才开始反向移动。如图6中的(d)部分和(e)部分所示，当位于虚拟摇杆10的可移动区域20之外的触控点30反向移动时，位于可移动区域20的边缘的虚拟摇杆10同时反向移动。
因此，相比于相关技术，本申请实施例提供的技术方案，可以快速改变虚拟摇杆的方向，不需要反向补偿距离，进一步可以快速操作虚拟对象移动。
结合参考图7，其示例性示出了触控点竖直移动的示意图。其中，图7中的(a)部分和(b)部分为相关技术提供的技术方案；图7中的(c)部分和图(d)部分为本申请提供的技术方案。对比(c)部分和(d)部分，可以看出，当位于虚拟摇杆10的可移动区域20之外的触控点30向上移动时，在虚拟摇杆10移动相同距离的情况下，相关技术提供的技术方案中，触控点30需要移动的距离大于本申请提供的技术方案中触控点30需要移动的距离。
因此，相比于相关技术，本申请实施例提供的技术方案，在虚拟摇杆移动同样距离时，触控点移动距离更小，即用户手指滑动距离更小，提高了用户的操作效率。
另外，由于虚拟摇杆的位置与触控点的位置实时同步变化，如反向移动和 竖直移动，相比于相关技术，本申请实施例提供的技术方案，在虚拟摇杆移动同样距离时，用户手指滑动距离更小，因此，用户可以将该虚拟摇杆移动至手指方便操作的位置，然后在该位置执行触控操作，如旋转、滑动和按压等，以控制虚拟摇杆的移动。从而，能够有效缓解因用户手指长度不同而导致的用户操作舒适度不一致的问题。
下述为本申请装置实施例，可以用于执行本申请方法实施例。对于本申请装置实施例中未披露的细节，请参照本申请方法实施例。
