Sprite class

hello,sorry for my bad english. i am using unity 3.5.7 version.
But now i make a game which is based on a game that i got from AssetStore on unity 4.3.4. There is a variable that using Sprite class, but i can’t use it on Unity 3.5.7. what can i do to make it work on unity 3.5.7?

and also there is “EaseType” on these code.
but i can’t use it too on unity 3.5.7. what code that can change “EaseType” on unity 3.5.7?
please help me. thank you.

well these are the codes
"
public Sprite[ ] sprites;
string[ ] sounds = new String[ ]{“perc”,“fx”,“glass”,“coo”,“water”,“cash”};
public EaseType easeType = EaseType.EaseOutBounce;
"

You can’t do anything to make it work on 3.5.7, which does not have the Sprite class. “EaseType” is not anything that’s part of Unity, it’s just something that someone put in the script and would work on any version.
