Example of Coding on haXe – Part 10

In this example you will see: feffects, feffects.Tween, flash.external.ExternalInterface.

NOTIFICATION: These examples are provided for educational purposes. Using this code is under your own responsibility and risk. The code is given ‘as is’. I do not take responsibilities of how they are used.

Code Example: Example_10_Sprite2D.hx:

/**

 * @description: In order to use Tweener you have to install the feffects
 * Install: neko-dev (Ubuntu: sudo apt-get Eneko-dev)
 * Execute: haxelib install feffects
 *	 Compile with flag: -lib feffects
 *	 Tweens available: feffects.easing.
 *	 Quint.easeIn, Quint.easeOut, Quint.easeInOut
 *	 Sine.easeIn, Sine.easeOut, Sine.easeInOut
 *	 Back.easeIn, Back.easeOut, Back.easeInOut
 *	 Bounce.easeIn, Bounce.easeOut, Bounce.easeInOut
 *	 Circ.easeIn, Circ.easeOut, Circ.easeInOut
 *	 Cubic.easeIn, Cubic.easeOut, Cubic.easeInOut
 *	 Elastic.easeIn, Elastic.easeOut, Elastic.easeInOut
 *	 Expo.easeIn, Expo.easeOut, Expo.easeInOut
 *	 Linear.easeIn, Linear.easeOut, Linear.easeInOut, Linear.easeNone
 *	 Quad.easeIn, Quad.easeOut, Quad.easeInOut
