触屏选中Unity3D场景中的GameObject对象代码


如何通过iphone触屏选中Unity3D场景中的GameObject对象代码?1.去camera的api里面看,有将2D的touch点产生一条从屏幕出发的ray,再用这个进行3D的碰撞,进而选取obj。2.最简单的方法是对物体先赋予Collider,任意一种碰撞器皆可。然后赋予一个脚本,脚本里写OnMouseDown就行,直接支持触摸。http://bbs.woxueyuan.com/data/attachment/forum/201609/24/105201fi33sbs3qvqnob3s.jpg
代码如下:<p style="border: 0px; border-image-source: initial; border-image-slice: initial; border-image-width: initial; border-image-outset: initial; border-image-repeat: initial;"><font color="#616161" face="微软雅黑"><span style="font-size: 14px; line-height: 30px;">Ray ray = mCamera.ScreenPointToRay (new Vector3 (touch.position.x, touch.position.y,0));</span></font></p><p style="border: 0px; border-image-source: initial; border-image-slice: initial; border-image-width: initial; border-image-outset: initial; border-image-repeat: initial;"><font color="#616161" face="微软雅黑"><span style="font-size: 14px; line-height: 30px;">RaycastHit[] hits;</span></font></p><p style="border: 0px; border-image-source: initial; border-image-slice: initial; border-image-width: initial; border-image-outset: initial; border-image-repeat: initial;"><span style="font-size: 14px; line-height: 30px;"><font color="#616161" face="微软雅黑"></font></span></p><p style="border: 0px; border-image-source: initial; border-image-slice: initial; border-image-width: initial; border-image-outset: initial; border-image-repeat: initial;"><font color="#616161" face="微软雅黑"><font color="#616161" face="微软雅黑"><span style="font-size: 14px; line-height: 30px;">hits = Physics.RaycastAll (ray, 50);</span></font></font></p>
