title: In Unity, how can I pass values from one script to another?
body: <p>In Unity, I want one object to have a falling speed variable that all the other objects can access. For various reasons, I can't use the inbuilt gravity for what I'm trying to do.</p>
  
  <p><strong>How can I access a variable in one object repeatedly, so that when it updates I get the updated variable, from another object?</strong></p>
