i need script c# scrollview object hide/unhide

metalstorm: ace would like to implement parts of the plane scrolling.

Current list of their friends by creating a number of objects

Left, right, scroll was implemented.

When you create an object, but as friends can create more than 100 objects can be.

Moving the scroll on the screen and the rest of the object being rendered, but hidden game speed and I would like to free up memory.

Please tell me how to do that.

my script source (i'm ngui is not used.)
