rts resources problem

Hi, I am making a rts game. I can add objects and each costs resources . I have 3 buildings and each have theirs own resources but i want a single place were they can get resources.
Can you help me ?
Cheers!

Else say i want to import a variable from a script in other script.

In all cases :

  • Get the component : GetComponent (ScriptName)
  • Get the variable : variable

If Scripname variable is static (global)

  • ScriptName.variable

Else (ScriptName variable is not static)

  • Get the object with ScriptName : GameObject.Find (“ObjectName”)
  • And from it, ScriptName.variable, so you have GameObject.Find (“ObjectName”).ScriptName.variable

I don’t think I get it…
