# anim.Edge

Function: anim.Edge( | old, delay, new, trans=None, prob=1)

This creates an edge that can be used with a anim.SMAnimation .

old - The name (a string) of the state that this transition is from.

delay - The number of seconds that this transition takes.

new - The name (a string) of the state that this transition is to.

trans - The transition that will be used to show the image found in the new state. If None, the image is show immediately.

prob - The number of times this edge is added. This can be used to make a transition more probable then others. For example, if one transition out of a state has prob=5, and the other has prob=1, then the one with prob=5 will execute 5/6 of the time, while the one with prob=1 will only occur 1/6 of the time. (Don't make this too large, as memory use is proportional to this value.)

## Example

    init:
        image blinking = anim.SMAnimation("a",
            anim.State("a", "eyes_open.png"),

            # This edge keeps us showing the eyes open for a second.
            anim.Edge("a", 1.0, "a", prob=60),

            # This edge causes the eyes to start closing...
            anim.Edge("a", 0.25, "b"),

            # ..because it brings us here.
            anim.State("b", "eyes_half.png"),

            # And so on...
            anim.Edge("b", 0.25, "c"),
            anim.State("c", "eyes_closed.png"),
            anim.Edge("c", 0.25, "d"),
            anim.State("d", "eyes_half.png"),

            # And back to a.
            anim.Edge("d", 0.5, "a")
            )
