Make a FlxSprite sway left and right?

Question

I want to make a FlxSprite object sway left and right at a set speed. How should I do this?

Answer 1

You may use the tweening system (FlxTween).

Here is a tutorial: [https://haxeflixel.com/documentation/flxtween/]

Answer 2

You probably want to tween the object

FlxTween.tween(spr, {x: 100}, 1);

This tweens the spr FlxSprite (can be used to tween any values though) to x position 100, in the duration of 1 second.

To have a sway, you might want to add both an ease to it, and make it PINGPONG loop.

FlxTween.tween(spr, {x: 100}, 1, {ease: FlxEase.quadInOut, type: PINGPONG});

The list of eases can be found in the FlxTween demo on the HaxeFlixel website if you wanna see out they all look.

The type is the loop type. By default it's set to ONESHOT, which plays the tween and keeps it there. PINGPONG hits the tween, but then tweens it back to the original position.
