Dir

public Dir()

Method Details

horizComp

public int horizComp()

Returns the horizontal motion of this direction: 1, 0 or -1.

vertComp

public int vertComp()

Returns the vertical motion of this direction: 1, 0 or -1.

canUntrans

public boolean canUntrans()

Returns whether this direction can be manually "untransitioned".

untransDir

public abstract ScreenSpace.Dir untransDir()

Returns the direction to use when untransing from this dir.

init

public void init(ScreenSpace.Screen oscreen,
 ScreenSpace.Screen nscreen)

Prepares oscreen and nscreen to be transitioned. oscreen is the currently visible screen and nscreen is the screen transitioning into view.

update

public abstract void update(ScreenSpace.Screen oscreen,
 ScreenSpace.Screen nscreen,
 float pct)

Updates the position of oscreen and nscreen based on pct.

Parameters:

pct - a value ranged [0,1] indicating degree of completeness.

finish

public void finish(ScreenSpace.Screen oscreen,
 ScreenSpace.Screen nscreen)

Cleans up after a transition. update(tripleplay.game.ScreenSpace.Screen,tripleplay.game.ScreenSpace.Screen,float) will have been called with pct equal to one immediately prior to this call, so this method is only needed when actual cleanup is needed, like the removal of custom shaders, etc.

Note also that the old screen's layer will have been made non-visible prior to this call. This call should not restore that visibility.

transitionTime

public float transitionTime()

Returns the duration of this transition (in millis).
