具体实施方式
为了使本技术领域的人员更好地理解本公开方案，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分的实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本公开保护的范围。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或 对于这些过程、方法、产品或设备固有的其它步骤或单元。
根据本公开其中一实施例，提供了一种三维游戏场景中虚拟资源的生成方法的实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1是根据本公开其中一实施例的三维游戏场景中虚拟资源的生成方法的流程图，所述游戏场景中包括至少一个虚拟对象和虚拟资源，所述虚拟资源包括已有资源和新建资源，所述三维游戏场景的空间被划分为多个长方体网格，所述新建资源为响应于用户输入的建造指令渲染生成的虚拟资源，所述方法可以包括如下步骤：
步骤S110，响应于所述建造指令，获取所述虚拟对象的当前位置及朝向，其中，所述建造指令包含所述新建资源的空间类型信息，所述新建资源的空间类型包括以下至少之一：沿每个长方体网格的垂直面建造、沿每个长方体网格的水平面建造和沿每个长方体网格的内坡面建造；
步骤S120，根据所述空间类型信息、所述虚拟对象的当前位置及朝向，在所述多个长方体网格中确定目标网格面作为所述新建资源的建造位置；
步骤S130，在所述目标网格面渲染生成所述新建资源。
通过本实施例中的三维游戏场景中虚拟资源的生成方法，一方面由于新建资源的建造位置位于划分游戏场景空间的长方体网格，大大降低了生成新建资源过程中的计算量，解决了玩家在游戏中自行建造虚拟资源的效率问题；另一方面，在玩家控制虚拟对象生成虚拟资源的过程中，可以直接根据虚拟对象的位置和朝向快速便捷地确定虚拟资源的建造位置，极大减轻了玩家的操作负担。
下面，将对本示例性实施例中虚拟资源的生成方法的各步骤作进一步地说明。
所述多个长方体网格仅仅为了便于确定虚拟资源的建造位置，将游戏场景空间划分为尺寸相同的多个长方体子空间，即网格仅是游戏场景空间的划分界限，并非游戏中的实体。所述长方体网格既可以是立方体(长宽高相同)，也可以是长宽高不完全相同的长方体。以下实施例以长宽相同，高与长宽不同的长方体网格为例进行说明，例如，长方体网格的长与宽均为5米，高为3.5米。
步骤S110，响应于所述建造指令，获取所述虚拟对象的当前位置及朝向，其中，所述建造指令包含所述新建资源的空间类型信息，所述新建资源的空间类型包括以下至少之一：沿每个长方体网格的垂直面建造、沿每个长方体网格的水平面建造和沿每 个长方体网格的内坡面建造。
所述新建资源的建造(即在游戏画面中渲染生成)由玩家的建造指令所触发，建造指令中至少包含玩家拟建造的虚拟资源(即新建资源)的空间类型，还可以包含新建资源的材料属性(如木材、混凝土、砖块等)和数量。所述新建资源的空间类型即新建资源相对于所述长方体网格的几何位置，可以是沿长方体网格的垂直面建造，沿长方体网格的水平面建造，沿长方体网格面的内坡面建造。所述垂直面即长方体网格中垂直于游戏场景地平面的四个面，所述水平面即长方体网格中平行于游戏场景地平面的两个面，所述内坡面即长方体网格内的对角截面(所述对角截面所在平面经过长方体网格水平面的两个边，并与长方体网格的两个垂直面相交)。以新建资源的材料属性为砖块为例，沿长方体网格垂直面建造的新建资源为垂直墙，沿长方体网格水平建造的新建资源为水平墙，沿建造位置为长方体网格的内坡面建造的新建资源为向上或向下的斜坡。图2是所述长方体网格的示意图，网格面202、203、204、206为垂直网格面，网格面201、205为水平网格面，网格面207则为其中一个内坡面。
步骤S120，根据所述空间类型信息、所述虚拟对象的当前位置及朝向，在所述多个长方体网格中确定目标网格面作为所述新建资源的建造位置。
新建资源的空间类型用于确定新建资源的相对于长方体网格的几何位置，而并非是确定新建资源的在游戏场景中的绝对位置。确定新建资源的建造位置需要确定新建资源所在的长方体网格面的具体位置。为获取新建资源的建造位置还需要取得所述虚拟对象在游戏场景中的当前位置及朝向，从而根据所述空间类型信息、所述虚拟对象当前位置及朝向，在所述多个长方体网格中确定目标网格面(即新建资源所在的具体长方体网格的具体面)作为所述新建资源的建造位置。在第一人称视角或第三人称视角的3D游戏中，玩家所控制的虚拟对象的朝向一般与游戏中的虚拟摄像机的朝向相同。为了使得玩家在发出建造指令时在其所控制的虚拟对象面前生成新建资源，目标网格面是根据新建资源的空间类型从虚拟对象附近且处于其视野范围内的长方体网格面中选择确定，具体的确定方法将在下文的实施例中详述。
步骤S130，在所述目标网格面渲染生成所述新建资源。
通过步骤S110和步骤S120确定目标网格面后，在该位置渲染生成新建资源，从而完成根据玩家的建造指令对新建资源的建造。
在可选的实施例中，所述已有资源的空间类型包括沿长方体网格的垂直面建造、沿长方体网格的水平面建造和沿长方体网格的内坡面建造。本实施例中，游戏中已有的虚拟资源(即已有资源)的空间类型与新建类型相同，也是沿长方体网格的垂直面、 水平面或内坡面渲染生成。由于新建资源与已有资源具有相同的空间类型，在生成新建资源时更容易与已有资源进行契合，同样也大大降低了计算量，提高了游戏的运行效率。
在可选的实施例中，所述目标网格面为至少一个长方体网格面。所述建造指令还可以保护新建资源的数量，当玩家在建造指令中确定生成多个新建资源时，建造新建资源所在的长方体网格面可以是多个。例如，玩家拟建造一面高5米(相对于游戏场景的地平面)，长15米的垂直墙，则需要在三个连续的长方体网格垂直面上生产新建资源，即目标网格面为三个长方体网格面。
在可选的实施例中，所述在所述目标网格面渲染生成所述新建资源，包括：在所述目标网格面渲染生成所述新建资源的预览信息；根据玩家所发送的确认指令在所述目标网格面渲染生成所述新建资源。目标网格面正式建造所述新建资源之前，先在目标网格面渲染生成新建资源的预览信息，当收到玩家发送的确认信息后再建造新建资源，一方面由游戏系统根据玩家控制的虚拟角色的当前位置及朝向自动确定新建资源的建造位置，减轻了玩家的操作负担，另一方面还可以提供玩家修正新建资源建造位置的机会，即当玩家发现系统自动确定的新建资源的建造位置不是想要的建造位置时可以放弃建造，另行发出建造指令以选择其他建造位置。
根据本公开提供的另一实施例，当所述新建资源的空间类型为沿长方体网格的垂直面建造时，根据所述新建资源的空间类型、所述虚拟对象的当前位置及朝向，在所述多个长方体网格中确定目标网格面作为所述新建资源的建造位置，包含以下步骤：
步骤S210，根据所述虚拟对象的当前位置计算所述虚拟对象当前所处网格及所述虚拟对象在当前所处网格中的第一位置；
步骤S220，根据所述当前所处网格及所述第一位置确定所述建造位置的候选网格面在水平参考面内的第二位置，其中，所述水平参考面平行于所述游戏场景的地平面；
步骤S230，根据所述虚拟对象的朝向在水平参考面内的投影从所述第二位置中确定所述目标网格面在水平参考面内的第三位置；
步骤S240，根据所述虚拟对象的当前位置及朝向和所述第三位置，确定所述目标网格面在垂直方向上的第四位置，其中，所述垂直方向垂直于所述三维游戏场景的地平面；
步骤S250，根据所述第三位置和第四位置得到所述建造位置。
为便于空间位置的判断，可在游戏场景中建立三维坐标系XYZ，X轴和Z轴所构 成的平面XZ平面平行于游戏场景的地平面(即上述水平参考面，坐标X和坐标Z一起确定在水平参考面内的位置)，Z轴垂直于游戏场景的地平面(上述垂直方向上的位置即在Z轴上的坐标)。步骤S210所述的虚拟对象在游戏场景中的当前位置可以通过其在该坐标系中的坐标来确定，每个长方体网格也有在游戏场景中也有对应的坐标来确定位置。步骤S210所述的虚拟对象在网格中的相对位置是指虚拟对象以其所处的网格为参照系的空间位置。
根据图3所示，在可选的实施例中，步骤S220所述的根据所述当前所处网格及所述相对位置确定所述建造位置的候选网格面在水平参考面内的第二位置，包括：在俯视图中(即水平参考面内)，将虚拟对象当前所处网格(即中间的大正方形，周围八个大正方形代表与虚拟对象当前所处网格相邻的网格)均分为九个小正方形，当虚拟对象位于中间的小正方形9内时，将中间大正方形四条边所对应的四个垂直面作为新建资源建造位置的候选网格面；当虚拟对象位于小正方形2、4、6、8这四个靠近中间大正方形四条边中点的四个小正方形内时，将中间大正方形以及与虚拟对象当前所处小正方形相邻的一个网格非共有的六个垂直面(在俯视图上看为呈“日”字形排列的两个大正方形外围的六个边)作为新建资源建造位置的候选网格面；当虚拟对象位于小正方形1、3、5、7这四个靠近大正方形四个角的四个小正方形内时，将中间大正方形以及以及与虚拟对象当前所处的小正方形相邻的三个网格非共有的八个垂直面(在俯视图上看为呈“田”字形排列的四个大正方形外围的八个边)作为新建资源建造位置的候选网格面。例如，当虚拟对象处于小正方形2所代表的网格中时，将中间大正方形和大正方形302外围的六个正方形边所代表的网格作为候选网格；当虚拟对象处于小正方形1所代表的网格中时，将中间大正方形和大正方形301、302、308外围的八个正方形边所代表的网格作为候选网格。
通过上述方法，可以将虚拟对象附近适宜距离范围内的网格面确定为新建资源的候选网格面，所述适当距离为大于网格面正方形边长1/3，小于网格面正方形边长的4/3。当然，上述适当距离也可以根据虚拟角色与网格的相对尺寸等因素进行调整。确定虚拟对象在网格中的相对位置的方法并不限于上述九宫格的判断方法，还可以通过其他方法，例如判断虚拟对象与当前所处网格四个面的距离是否在预定的阈值范围之内。
在可选的实施例中，步骤S230所述的根据所述虚拟对象的朝向在水平参考面内的投影从所述第二位置中确定所述目标网格面在水平参考面内的第三位置，包括：获取以所述虚拟对象所在位置为起点所述虚拟对象的朝向为方向的射线在水平参考面内的投影，在水平参考面内与该投影相交的候选网格面即目标网格面，目标网格面在水平 面参考面内的位置即第三位置，即从步骤S220所获得的多个所述第二位置中确定第三位置，由此得到目标网格面在水平参考面内的位置。从俯视图上来看，也可以看作是从虚拟对象所在位置向代表候选网格面的各个正方形边的端点连续，所述连线将虚拟对象周围的360度区域划分成与候选网格面个数相同的子角区域，再判断虚拟对象的视线(所述虚拟对象所在位置为起点所述虚拟对象的朝向为方向的射线)位于上述哪个子角区域，然后将视线所处的子角区域所对应的候选网格面作为目标网格面。
通过上述步骤获得目标网格面在水平参考面的位置后，还需要确定目标网格面在垂直方向上的位置，根据图4所示，在可选的实施例中，步骤S240所述的根据所述虚拟对象的当前位置及朝向和所述第三位置，确定所述目标网格面在垂直方向上的第四位置，包括：目标网格面在垂直方向上的候选位置包括高中低三个(即图4中的网格面406、405、404)，位于中位的候选网格面405在垂直方向上的位置与虚拟对象401所在网格相同(即Z坐标相同)，位于高位的候选网格面406在垂直方向上的位置高于虚拟对象401所在网格，位于低位的候选网格面404在垂直方向上的位置低于虚拟对象401所在网格；获取虚拟对象的视线402与候选网格面所在平面的交点407；计算上述高中低三个候选位置上的候选网格面的中点与上述交点407的距离；将中点与上述交点407的距离最短的候选网格面作为目标网格面。从图4来块，网格面406的中点距离交点407最近，则将网格面406确定为目标网格面。
在可选的实施例中，为了避免虚拟对象与候选网格面所在平面的夹角太小(即虚拟对象视线的俯仰角的绝对值接近90度)从而导致上述交点的位置太远，可以将虚拟对象的俯仰角的绝对值限制在80度之内，当然也可以根据需要设置为其他角度。
在可选的实施例中，为了避免选中的目标网格面无法建造新建资源(如既不与游戏场景相连，也不与其他虚拟资源相连)，可以先判断已选中的目标网格面能否建造新建资源；如果不能建造新建资源，则继续在垂直方向上的三个候选网格面的另外两个网格面中选取与先前确定的目标网格面相邻的一个，判断能否建造新建资源；如果第二个目标网格面可以建造新建资源，则确定为最终的目标网格面；如果第二个目标网格面不能建造新建资源，则提示玩家当前位置无法建造新建资源。
在步骤S250，根据步骤S230中所获取的所述目标网格面在在水平参考面内的第三位置和步骤S240中所获取的目标网格面在垂直方向上的第四位置，可以在上述三维游戏场景的三维坐标中确定所述建造位置。
在本公开的另一可选实施例中，当所述新建资源的空间类型为沿长方体网格的水平面建造时，根据所述新建资源的空间类型、所述虚拟对象的当前位置及朝向，在所 述多个长方体网格中确定目标网格面作为所述建造位置，包括以下步骤：
步骤S310，根据所述虚拟对象的当前位置计算所述虚拟对象当前所处网格；
步骤S320，根据所述虚拟对象的朝向及所述当前所处网格确定所述目标网格面在垂直方向上的第一位置，其中，所述垂直方向垂直于所述三维游戏场景的地平面；
步骤S330，根据所述虚拟对象的当前位置及朝向、所述当前所处网格、所述第一位置确定所述目标网格面在水平参考面内的第二位置，其中，所述水平参考面平行于所述游戏场景的地平面；
步骤S340，根据所述第一位置和所述第二位置得到所述建造位置。
当新建资源的空间类型为沿长方体网格的水平面建造时，例如平行于游戏场景的地平面的水平墙面，则目标网格面也是虚拟对象当前所处网格及相邻网格中的其中一个水平面，故也需要先根据所述虚拟对象当前位置计算所述虚拟对象当前所处网格。
步骤S320中所述确定目标网格面在垂直方向上的第一位置，即确定新建资源所处的目标网格面所在的平面，所述目标网格面所在的平面将从虚拟对象所在网格的上下两个水平面所在的平面中选取，在可选的实施例中选取方法可以为：判断虚拟对象的视线的俯仰角，如俯仰角大于零(即虚拟对象仰视)，则选取垂直方向位置为上的水平面所在的平面(如图4中的平面503)；如俯仰角小于零(即虚拟对象俯视)，则选取垂直方向位置为下的水平面所在的平面(如图4中的平面504)。如图5所示，虚拟对象501的视线502的俯仰角大于零，则确定虚拟对象所处网格中位置为上的水平面503作为目标网格面所在的平面。
在可选的实施例中，为了避免虚拟对象的俯仰角接近零时上述交点接近无限远，可以将0至5度之间的俯仰角设置为5度，-5度至0度之间的俯仰角设置为-5度。当然，也可以根据需要设置为其他角度。
步骤S330中所述目标网格面在水平参考面内的位置与目标网格面在其在所在平面中的位置相同，因为水平参考面和目标网格面所在平面都是平行于游戏场景地平面的平面(二者的坐标X和坐标Z相同)。如图6所示，在可选的实施例中，所述确定所述目标网格面在水平参考面内的位置可以为：计算虚拟对象601的视线602与所述目标网格面所在平面的交点603；计算上述交点603与虚拟对象601所在网格及相邻网格在目标网格面所在平面内的网格面的中点的距离；选取中点与上述交点最近的网格面(如图6中的网格面604)作为目标网格面。
在可选的实施例中，在计算上述交点与虚拟对象所在网格及相邻网格在目标网格 面所在平面内的网格面的中点的距离之前，可以先在目标网格面所在平面内根据虚拟对象的朝向从虚拟对象所在网格的相邻网格中选取三个网格面作为候选网格面，例如当虚拟对象的朝向为东北方向时，选择东北方向的三个网格面(如图6中的604、605、607)作为候选网格面。
在本公开的其中一可选实施例中，当所述新建资源的空间类型为沿长方体网格的内坡面建造时，根据所述新建资源的空间类型、所述虚拟对象的当前位置及朝向，在所述多个长方体网格中确定目标网格面作为所述建造位置，包括：
步骤S410，根据所述虚拟对象的朝向在水平参考面内的投影确定所述目标网格面在水平参考面上的延伸方向，其中，所述水平参考面平行于所述三维游戏场景的地平面；
步骤S420，根据所述虚拟对象的当前位置计算所述虚拟对象当前所处网格及其在当前所处网格中的第一位置；
步骤S430，根据所述虚拟对象的朝向、所述当前所处网格及所述第一位置确定所述目标网格面在水平参考面内的第二位置；
步骤S440，根据所述虚拟对象的朝向和所述当前所处网格确定所述目标网格面在垂直方向上的第三位置，其中，所述垂直方向垂直于所述三维游戏场景的地平面；
步骤S450，根据所述第二位置及所述第三位置得出所述建造位置。
沿长方体网格的内坡面建造的新建资源(如云梯、斜坡)的建造位置除了需要确定水平面参考面上的位置和垂直方向上的位置外，还需要确定其在水平参考面上的延伸方向。
如图7所示，在一可选实施例中，步骤S420中所述当前所处网格中的第一位置，可以是在水平参考面内，在目标网格面的延伸方向702上将当前所处网格划分为前后两部分，前部分703在水平参考面上占70％，后部分704在水平参考面上占30％；在垂直于所述延伸方向的方向上将当前所处网格划分为左中右三部分(如图4中的705、704、706)，在水平参考面上分别占30％、40％和30％。为方便论述，将目标网格面延伸方向表述为前方，相反方向为后方，将垂直于目标网格面延伸方向的方向分为为左方和右方。
在一可选实施例中，步骤S430中确定所述目标网格面在水平参考面内的第二位置，包括：以所述当前所处网格在水平参考面内的位置为基准，根据所述虚拟对象701在当前所处网格中的相对位置及虚拟对象701的朝向(即虚拟对象701的视线)，判断是 否进行前后左右偏移(偏移以一个网格为单位)，从而确定所述目标网格面在水平参考面内的位置。当虚拟对象701位于左部分且视线向左偏移超过15度时，则向左偏移一个网格；当虚拟对象701位于右部分且视线向右偏移超过15度时，则向右偏移一个网格；其他情况下，则无需进行左右偏移。当虚拟对象701位于前部分且视线的俯仰角的绝对值小于30度时，向前偏移一个网格；当虚拟对象701位于后部分时或虚拟对象701位于前部分且视线的俯仰角的绝对值大于30度时，则无需进行前后偏移。
在一可选实施例中，步骤S440中确定所述目标网格面在垂直方向上的第三位置，包括：以所述当前所处网格在垂直方向上的位置为基准，根据虚拟对象的朝向(即虚拟对象的视线)，判断是否进行上下偏移(偏移以一个网格为单位)，从而确定所述目标网格面在垂直方向上的位置；当虚拟对象的视线的俯仰角大于30度时，向上偏移一个网格；当虚拟对象的视线的俯仰角小于-30度时，向下偏移一个网格；其他情况下，则无需进行上下偏移。
在一可选实施例中，所述建造指令包含所述新建资源在垂直方向上的延伸方向；当所述延伸方向为上时，所述虚拟对象的当前位置为所述虚拟对象的头部的当前位置；当所述延伸方向为下时，所述虚拟对象的当前位置为所述虚拟对象的脚部的当前位置。例如，当玩家确定建造的新建资源为向上延伸的云梯，则将虚拟对象的头部的当前位置作为虚拟对象的当前位置用于确定目标网格面；当玩家确定建造的新建资源为向下延伸的斜坡，则将虚拟对象的脚部的当前位置作为虚拟对象的当前位置用于确定目标网格面。
如上述方法所确定的目标网格面无法建造新建资源(例如，已有一个云梯或斜坡)，则可以对目标网格面所在网格的位置进行偏移。在一可选的实施例中，如遇目标网格面无法建造新建资源，则将目标网格的位置向前偏移一个网格；如在确定目标网格位置时未进行上下偏移，则向上偏移一个网格；如在确定目标网格位置时进行过上下偏移，则取消上下偏移，使得目标网格的高度与虚拟对象所处网格的高度相同。
