Inherits from CCNode : CCResponder : NSObject
Declared in CCProgressNode.h

Overview

CCProgressNode displays a sprite with a progressive reveal.

Notes

  • Progress type can currently be Radial, Horizontal or vertical.

  • Midpoint is used to modify the start position:

    • Radial type the mid point changes the center point.
    • Bar type the midpoint changes the bar growth, it expands from the center but clamps to the sprites edge:
      • Left -> Right use (0,0)
      • Right -> Left use (1,y)
      • Bottom -> Top use (x,0)
      • Top -> Bottom use (x,1)

  • Progress percentage is 0 -> 100.

  • Bar change rate allows the bar type to move the component at a specific rate.
    • Set the rate to zero to make sure it stays at 100%
    • Example: If you want a Left -> Right bar and also have the height grow set the rate to (0,1) and modpoint to (0,0.5f)
