Detailed Description

Action used to animate any value in range [from,to] over specified time interval.

Member Function Documentation

static ActionFloat* create ( float  duration, float  from, float  to, ActionFloatCallback  callback  )

static

Creates FloatAction with specified duration, from value, to value and callback to report back results.

Parameters

duration	of the action
from	value to start from
to	value to be at the end of the action
callback	to report back result

Returns

An autoreleased ActionFloat object

void update ( float  time )

overridevirtual

Called once per frame.

time a value between 0 and 1.

For example:

• 0 Means that the action just started.
• 0.5 Means that the action is in the middle.
• 1 Means that the action is over.

Parameters

time	A value between 0 and 1.

Reimplemented from Action.
