Code Snippets: Camera Control

Introduction

The controlling of the camera is quite important. How else would the player to see what is going on? :)

Render-To-Texture

In this case it is used for a UI

     void InitCameraViewFromTarget()
       {
           int textureSize = 256;

           //Texture cameraTexture
           cameraTexture = TextureManager.Instance.Create(
               TextureManager.Instance.GetUniqueName("RemoteView"), Texture.Type.Type2D,
               new Vec2i(textureSize, textureSize), 1, 0, PixelFormat.R8G8B8, Texture.Usage.RenderTarget);

           RenderTexture renderTexture = cameraTexture.GetBuffer().GetRenderTarget();

           rmCamera = SceneManager.Instance.CreateCamera();

           rmCamera.ProjectionType = ProjectionTypes.Perspective;
           rmCamera.PolygonMode = PolygonMode.Wireframe;

           renderTexture.AddViewport(rmCamera);


       }

       void GetCameraViewFromTarget()
        {
            Mech mecha = GetPlayerUnit() as Mech;
            Unit unit;

            if (mecha == null) return;
            else if (mecha != null && mecha.CurrentMissileTarget != null)
            {
                unit = mecha.CurrentMissileTarget;
            }
            else
            {
                hudControl.Controls["Game/TargetWindow"].BackTexture = null;
                 rmCamera.Visible = false;
                 return;
            } 

            Vec3 dir = (unit.Position - mecha.Position); 

            rmCamera.FixedUp = (Vec3.ZAxis); 

            rmCamera.Visible = true;
           
            rmCamera.Position = mecha.CurrentMissileTarget.Position + mecha.CurrentMissileTarget.Rotation.GetDirection() * 10f;
            rmCamera.LookAt(mecha.CurrentMissileTarget.Position);
           
            rmCamera.PolygonMode = PolygonMode.Wireframe;
            rmCamera.NearClipDistance = 1.0f;
            rmCamera.FarClipDistance = (mecha.CurrentMissileTarget.Position - rmCamera.Position).LengthFast() * 1.3f;
            hudControl.Controls["Game/TargetWindow"].BackTexture = cameraTexture;

        }
