@Js

A collection of standard animation functions as defined by Mappy. FIXME: http://fantom.org/sidewalk/topic/1973# Should be const class with static fields

animateOnce

Source

|AnimBlock animateOnce := |AnimBlock->Void| { ... }

AN_ONCE

After the animation sequence finishes the currentFrameIndex resets to the first frame and the animType changes to animateOnceFinished.

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 0 1 2 3 4 0 0 0 0 0 0 0 0 0 0 0 0 0 . . . ]

animateOnceAndHalt

Source

|AnimBlock animateOnceAndHalt := |AnimBlock->Void| { ... }

AN_ONCEH

After the animation sequence finishes the current frame sticks to the last frame. Unlike animateOnce the animType does not change.

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 0 1 2 3 4 4 4 4 4 4 4 4 4 4 4 4 4 4 . . . ]

animateOnceFinished

Source

|AnimBlock animateOnceFinished := |AnimBlock->Void| { ... }

AN_ONCES

The animation type is automatically set to this after the animateOnce sequence has finished. animateOnceFinished behaves the same as none.

static AnimFunc instance()

I lie!

loopForward

Source

|AnimBlock loopForward := |AnimBlock->Void| { ... }

AN_LOOPF

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 0 1 2 3 4 0 1 2 3 4 0 1 2 3 4 0 1 3 . . . ]

loopReverse

Source

|AnimBlock loopReverse := |AnimBlock->Void| { ... }

AN_LOOPR

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 4 3 2 1 0 4 3 2 1 0 4 3 2 1 0 4 3 2 . . . ]

none

Source

|AnimBlock none := |Obj?->Void| { ... }

AN_NONE

Do Not Animate. By setting the animation type to none the current frame will stay as it is.

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 . . . ]

pingPongForwardOutwardLeg

Source

|AnimBlock pingPongForwardOutwardLeg := |AnimBlock->Void| { ... }

AN_PPFF

When the animation sequence reaches the end of the forward ping the animType changes to pingPongForwardReturnLeg and the sequence begins its return journey.

It could be argued there is no difference between pingPongForwardOutwardLeg and pingPongReverseReturnLeg

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 0 1 2 3 4 3 2 1 0 1 2 3 4 3 2 1 0 1 . . . ]

pingPongForwardReturnLeg

Source

|AnimBlock pingPongForwardReturnLeg := |AnimBlock->Void| { ... }

AN_PPFR

When the animation sequence reaches the end of the forward pong the animType changes to pingPongForwardOutwardLeg and the sequence starts all over again.

It could be argued there is no difference between pingPongForwardReturnLeg and pingPongReverseOutwardLeg

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 4 3 2 1 0 1 2 3 4 3 2 1 0 1 2 3 4 3 . . . ]

pingPongReverseOutwardLeg

Source

|AnimBlock pingPongReverseOutwardLeg := |AnimBlock->Void| { ... }

AN_PPRF

When the animation sequence reaches the end of the reverse ping the animType changes to pingPongReverseReturnLeg and the sequence begins its return journey.

It could be argued there is no difference between pingPongReverseOutwardLeg and pingPongForwardReturnLeg

Given 5 frames of animation, currentFrameIndex would update as follows:

[ 4 3 2 1 0 1 2 3 4 3 2 1 0 1 2 3 4 3 . . . ]

pingPongReverseReturnLeg

Source

|AnimBlock pingPongReverseReturnLeg := |AnimBlock->Void| { ... }

Fandoc ERRORS:
Line 12 - Invalid annotation []

When the animation sequence reaches the end of the reverse 'pong' the
[animType]`AnimBlock.animType` changes to 
[pingPongReverseOutwardLeg]`AnimType.pingPongReverseOutwardLeg` and the sequence starts all
over again.

It could be argued there is no difference between
[pingPongReverseReturnLeg]`AnimType.pingPongReverseReturnLeg` and
[pingPongForwardOutwardLeg]`AnimType.pingPongForwardOutwardLeg` 
 
Given 5 frames of animation, [currentFrameIndex]`AnimBlock.currentFrameIndex` would update 
as follows:
 [ 0 1 2 3 4 3 2 1 0 1 2 3 4 3 2 1 0 1 . . . ]
