large slider in the unity 3D

Hi All,

In my game I want to implement the slider for controlling the speed of player. I used the GUI.VerticalSlider but it is small. I tried increase the rect of vertical slider but it does not shows the large slider, only area of interaction is increased. I want to show the slider large.

Also I am facing another problem in my game, it gets slower down and does not response to touch events after some time. I am unable to find the where exactly problem is.

How I know the graphics which I got is low poly or high poly? Is that makes slower my game? What are the standards for creating 3D graphics for iPhone?

To make custom looking GUI controls, like a larger slider, you must create and use a custom GUISkin. See the docs.
