Thanks
Think I've sorted it now. I have a slider that will adjust the light intensity as the slider is adjusted and also if the up or down arrow keys are pressed.
The next thing I'm struggling with is displaying the light intensity on the screen. The variable is a float and so I have tried to convert the float to a string and then used a 'set gui text' state to display on the screen. But no good at the moment. I remember having a lot of trouble getting to grip with displaying scores and the like on the screen but i couldn't remember what I'm supposed to use.. e.g GameObject/UI/Text doesn't work, nor GameObject/UI/Canvas. Also tried Component/UI/Text but that doesn't seem to work either.
Can someone help?
So I have a light intensity set as a float. I'd like to have this float variable displayed on the game screen so when the slider is used or the UP/DOWN button is pressed the light intensity float also changes on screen.
thanks
