实现卷轴效果的脚本

// Scroll main texture based on time
 
　　var scrollSpeed = -0.5;
 
　　// This must be set to override a bug where Render Order
 
　　// of the tunnel objects is lost when SetTextureOffset is used
 
　　var queue = 0;
 
　　private var offset = 0.0;
 
　　function Update ()
 
　　{
 
　　offset = Time.time * scrollSpeed;
 
　　renderer.material.SetTextureOffset (“_MainTex”, Vector2(offset,0));
 
　　renderer.material.renderQueue = queue;
 
　　}
