Description
本发明实施例属于画面显示领域，尤其涉及一种游戏地图的物体绘制方法及装置。
网络游戏经常会有各种场景，每个场景都有对应的地图。在地图中可能有大量（比如超过1000）的物体（可能是怪物，也可能是花花草草），为了能够正确显示地图上的物体，需要对这些物体进行绘图和逻辑处理。其中，绘图和处理逻辑所消耗的时间比大约为10:1，当物体非常多的时候，绘图占用的时间也会非常多，而当绘图和处理逻辑所占用的时间之和大于游戏的绘图间隔时间（比如为人眼能反应的最大间隔时间1/60秒，超过这个间隔时间，人眼就能分辨出卡顿的情况）时游戏就会发生卡顿现象。
现有的游戏地图绘制方法中，通常是将地图上的物体都绘制一遍，再根据视口（可理解为镜头）能够呈现的物体显示已绘制的物体。由于现有方法在显示物体前已绘制了所有的物体，而绘制所有物体耗费了过多的时间，因此导致显示物体的时间过慢，卡顿现象严重，用户体验较低。
本发明实施例提供了一种游戏地图的物体绘制方法及装置，旨在解决现有方法绘制物体的数量过多，导致显示物体过慢的问题。
本发明实施例是这样实现的，一种游戏地图的物体绘制方法，所述方法包括：
获取屏幕的尺寸以及游戏地图的物体的基本信息，所述物体的基本信息包括物体的位置信息和物体的尺寸；
根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外；
在所述物体在视口外时，不绘制所述物体。
本发明实施例的另一目的在于提供一种游戏地图的物体绘制装置，所述装置包括：
物体的基本信息获取单元，用于获取屏幕的尺寸以及游戏地图的物体的基本信息，所述物体的基本信息包括物体的位置信息和物体的尺寸；
视口外物体判断单元，用于根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外；
物体不绘制单元，用于在所述物体在视口外时，不绘制所述物体。
在本发明实施例中，由于无需绘制视口外的物体，因此减少了需绘制的物体的数量，从而加快了物体的显示速度，提高了用户的良好体验。
图1是本发明第一实施例提供的一种游戏地图的物体绘制方法的流程图；
图2是本发明第二实施例提供的另一种游戏地图的物体绘制方法的流程图；
图3是本发明第二实施例提供的采用现有方法绘制一地图的结果示意图；
图4是本发明第二实施例提供的采用本发明实施例的游戏地图的物体绘制方法绘制与图3同样地图的结果示意图；
图5是本发明第三实施例提供的一种游戏地图的物体绘制装置的结构图。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例中，获取屏幕的尺寸以及游戏地图的物体的基本信息，所述物体的基本信息包括物体的位置信息和物体的尺寸，根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外，在所述物体在视口外时，不绘制所述物体。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
实施例一：
图1示出了本发明第一实施例提供的一种游戏地图的物体绘制方法的流程图，详述如下：
步骤S11，获取屏幕的尺寸以及游戏地图的物体的基本信息，所述物体的基本信息包括物体的位置信息和物体的尺寸。
该步骤中，物体的位置信息为物体在游戏地图上的坐标位置信息。
步骤S12，根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外。
该步骤中的视口可理解为镜头，视口内的物体可被用户看到。以一个大街为例，游戏的场景是一条大街，大街上有熙熙攘攘的行人，游戏的视口不能将整个大街一次性显示出来，需要通过切换视口或者移动视口才能显示其它部分。有些行人在视口里面、有些行人在视口的外面，用户可看到游戏视口内的行人。
其中，所述根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外，具体包括：
计算下列式子的值：（x+0.5*w）、（x-0.5*w）、（y+0.5*h）以及（y-0.5*h），其中，物体的位置信息为（x，y），物体的尺寸为（w，h），屏幕的尺寸为（screenW，screenH）；
在x+0.5*w<0且x-0.5*w>screenW且y+0.5*h<0且y-0.5*h>screenH时，判断物体在视口外。在cocos2d-x中物体的位置是以中心点为准的，假设物体的位置是（x，y），物体的尺寸为（w，h），屏幕的尺寸为（screenW，ScreenH）。当x+0.5*w<0且x-0.5w>screenW且y+0.5*h<0且y-0.5*h>screenH，则判定物体在视口外；进一步地，当x-0.5*w>0且x+0.5w<screenW且y-0.5*h>0且y+0.5*h<screenH，则判定物体完全在视口内；其它情况则判定物体部分在视口内。
步骤S13，在所述物体在视口外时，不绘制所述物体。
该步骤中，当判断出物体在视口外时，引擎不绘制视口外的物体，由于无需绘制视口外的物体，因此减少了需绘制的物体的数量，从而加快了物体的显示速度，提高了用户的良好体验。
实施例二：
图2示出了本发明第二实施例提供的另一种游戏地图的物体绘制方法的流程图，本实施例中，在实施例一的基础上增加步骤S21，详述如下：
步骤S21，获取用户的前进方向。
该步骤中，可通过确定光标的前进方向确定用户的前进方向。当然，若在游戏中没显示光标，则根据隐藏的光标的前进方向确定用户的前进方向。
步骤S22，获取屏幕的尺寸以及用户前进方向的中心点预设范围内游戏地图的物体的基本信息。
该步骤中，用户前进方向的中心点可以设置为已执行前进动作后得到的当前画面的中心点。为了能够提前判断出物体是否在视口外，预设范围可设置为包括屏幕外的物体的范围，即用户前进方向的中心点预设范围内的游戏地图的物体包括屏幕内显示的物体，也包括部分屏幕外还没显示的物体，这样，当用户前进到当前画面时，由于已提前获取该当前画面的物体的基本信息，提前判断该当前画面的物体是否在视口外，因此进一步加快绘制物体的速度。
其中，所述获取屏幕的尺寸以及用户的前进方向预设范围内游戏地图的物体的基本信息，具体包括：
A1、判断用户当前前进方向的中心点与用户上一次前进方向的中心点的距离是否超过预设的距离阈值。由于获取游戏地图的物体的基本信息，判断物体是否在视口外仍需要占用一定的资源，因此，为了避免在画面移动不大的情况下获取游戏地图的物体的基本信息，节省资源，需要判断何时获取游戏地图的物体的基本信息。
A2、在用户当前前进方向的中心点与用户上一次前进方向的中心点的距离超过预设的距离阈值时，获取屏幕的尺寸以及用户的前进方向预设范围内游戏地图的物体的基本信息。
步骤S23，根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外。
步骤S24，在所述物体在视口外时，不绘制所述物体。
具体地，在所述物体在视口外时，设置所述物体为不可见状态，引擎在判断出物体为不可见状态时，不绘制所述物体。
可选地，在所述物体完全在视口内以及在所述物体部分在视口内时，绘制所述物体。
该步骤中，在所述物体完全在视口内以及在所述物体部分在视口内时，设置所述物体为可见状态，引擎在判断出物体为可见状态时，绘制所述物体。由于只在物体为可见状态时，才绘制所述物体，因此，减少了需绘制的物体的数量，从而极大提高了物体的绘制速度。
如图3、图4所示，当地图大小为3096*2400，物体数量为1000，屏幕尺寸（视口大小）为：1280*800，物体的图片尺寸为：480*
320，若使用原有的方法，根据图3左下角的调试信息，可知显示绘图间隔为0.021s。但采用本发明实施提供的方法后，如图4左下角所示，绘图间隔变为0.006s，极大提高了物体的绘制速度，缩短了绘制间隔。
应理解，在本发明实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
实施例三：
图5示出了本发明第三实施例提供的一种游戏地图的物体绘制装置的结构图，该游戏地图的物体绘制装置可以包括经无线接入网RAN与一个或多个核心网进行通信的用户设备，该用户设备可以是移动电话（或称为“蜂窝”电话）、具有移动设备的计算机等，例如，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。又例如，该移动设备可以包括智能手机、平板电脑、个人数字助理PDA、销售终端POS或车载电脑等。为了便于说明，仅示出了与本发明实施例相关的部分。
该游戏地图的物体绘制装置包括：物体的基本信息获取单元51、视口外物体判断单元52、物体不绘制单元53。其中：
物体的基本信息获取单元51，用于获取屏幕的尺寸以及游戏地图的物体的基本信息，所述物体的基本信息包括物体的位置信息和物体的尺寸。
其中，物体的位置信息为物体在游戏地图上的坐标位置信息。
视口外物体判断单元52，用于根据所述屏幕的尺寸以及游戏地图的物体的基本信息判断所述物体是否在视口外。
其中，所述视口外物体判断单元52包括：
数值计算模块，用于计算下列式子的值：（x+0.5*w）、（x-0.5*w）、（y+0.5*h）以及（y-0.5*h），其中，物体的位置信息为（x，y），物体的尺寸为（w，h），屏幕的尺寸为（screenW，screenH）。
视口外判定模块，用于在x+0.5*w<0且x-0.5*w>screenW且y+0.5*h<0且y-0.5*h>screenH时，判定物体在视口外。
进一步地，当x-0.5*w>0且x+0.5w<screenW且y-0.5*h>0且y+0.5*h<screenH，则判定物体完全在视口内；其它情况则判定物体部分在视口内。
物体不绘制单元53，用于在所述物体在视口外时，不绘制所述物体。
具体地，在所述物体在视口外时，设置所述物体为不可见状态，引擎在判断出物体为不可见状态时，不绘制所述物体。由于无需绘制视口外的物体，因此减少了需绘制的物体的数量，从而加快了物体的显示速度，提高了用户的良好体验。
可选地，所述游戏地图的物体绘制装置包括：
前进方向获取单元，用于获取用户的前进方向。具体地，可通过确定光标的前进方向确定用户的前进方向。当然，若在游戏中没显示光标，则根据隐藏的光标的前进方向确定用户的前进方向。
此时，所述物体的基本信息获取单元具体用于获取屏幕的尺寸以及用户前进方向的中心点预设范围内游戏地图的物体的基本信息。其中，用户前进方向的中心点可以设置为已执行前进动作后得到的当前画面的中心点。
进一步地，所述物体的基本信息获取单元51包括：
相邻两次画面移动距离判断模块，用于判断用户当前前进方向的中心点与用户上一次前进方向的中心点的距离是否超过预设的距离阈值。由于获取游戏地图的物体的基本信息，判断物体是否在视口外仍需要占用一定的资源，因此，为了避免在画面移动不大的情况下获取游戏地图的物体的基本信息，节省资源，需要判断何时获取游戏地图的物体的基本信息。
距离超出阈值时操作模块，用于在用户当前前进方向的中心点与用户上一次前进方向的中心点的距离超过预设的距离阈值时，获取屏幕的尺寸以及用户的前进方向预设范围内游戏地图的物体的基本信息。
可选地，所述游戏地图的物体绘制装置包括：
物体绘制单元，用于在所述物体完全在视口内以及在所述物体部分在视口内时，绘制所述物体。具体地，在所述物体完全在视口内以及在所述物体部分在视口内时，设置所述物体为可见状态，引擎在判断出物体为可见状态时，绘制所述物体。由于只在物体为可见状态时，才绘制所述物体，因此，减少了需绘制的物体的数量，从而极大提高了物体的绘制速度。
本发明实施例中，由于无需绘制视口外的物体，因此减少了需绘制的物体的数量，从而加快了物体的显示速度，提高了用户的良好体验。
