    gc - The GameContainer of the game
    
    screenManager - The ScreenManager of the game
    
    delta - The time in seconds since the last update
  - interpolate
```
void interpolate(GameContainer gc,
                 float alpha)
```
    Interpolate between the previous and current state
    
    Parameters:

```
    Called before the transition in
    
    Parameters:
    
    transitionIn - The Transition in to this screen
  - postTransitionIn
```
void postTransitionIn(Transition transitionIn)
```
    Called after the transition in
    
    Parameters:
    
    transitionIn - The Transition in to this screen
  - preTransitionOut
```
void preTransitionOut(Transition transitionOut)
```
    Called before the transition out
    
    Parameters:
    
    transitionOut - The Transition out from this screen
  - postTransitionOut
