Question

我正在进行一个空间侧滚动游戏的项目，我试图使引擎的相机像旧的太空射击游戏一样（单独移动，当玩家棋子保持闲置时，将其单独移动到其边缘），我试图找到太空船控制器的教程，但我只找到了陆地单位的摄像头选项。

我的解决方法是覆盖默认的虚幻相机并自行编程。以下是如何完成此操作的快速指南。这真的很容易。

第一步是创建自定义Camera类。这里：

class MyCustomCamera extends Camera;

//Camera variables
var Vector mCameraPosition;
var Rotator mCameraOrientation;
var float mCustomFOV;

/**Init function of the camera
*/ 
function InitializeFor(PlayerController PC)
{
      Super.InitializeFor(PC);
      mCameraPosition = Vect(0,0,0);
      //Etc...
}

/**Update function of the camera
*/
function UpdateViewTarget(out TViewTarget OutVT, float DeltaTime)
{
    //This is the meat of the code, here you can set the camera position at each 
    //frame, it's orientation and FOV if need be (or anything else really)

    OutVT.POV.Location = mCameraPosition;
    OutVT.POV.Rotation = mCameraOrientation;
    OutVT.POV.FOV = mCustomFOV;
}

下一步和最后一步是将新的自定义相机设置为默认相机。为此，在您的PlayerController类中添加这是defaultproperties块：

CameraClass=class'MyCustomCamera'

现在您需要特别需要滚动＆＃34;相机，你可以在更新功能中做一些简单的事情：

/**Update function of the camera
*/
function UpdateViewTarget(out TViewTarget OutVT, float DeltaTime)
{
    //This is the meat of the code, here you can set the camera position at each 
    //frame, it's orientation and FOV if need be (or anything else really)

    //This will make your camera move on the X axis at speed 50 units per second.
    mCameraPosition += Vect(50*DeltaTime,0,0);

    OutVT.POV.Location = mCameraPosition;
    OutVT.POV.Rotation = mCameraOrientation;
    OutVT.POV.FOV = mCustomFOV;
}

希望这能让你开始！
