회전하면서 가속도
언어/ActionScript 3.0

점점 미친듯이 회전.
package {
import flash.display.Sprite;
import flash.events.Event;
[SWF(width="800", height="600", backgroundColor="#ffffff", framerate="30")]
public class oscillation extends Sprite
{
private var _sprite:Sprite;
private var _angle:Number = 0;
private var _xRadius:Number = 100;
private var _yRadius:Number = 100;
private var _vx:Number = 0;
private var _vy:Number = 0;
private var _ax:Number = .02;
private var _ay:Number = .2;
public function oscillation()
{
_sprite = new Sprite();
_sprite.graphics.beginFill(0x0000ff, 100);
_sprite.graphics.drawCircle(0, 0, 25);
_sprite.graphics.endFill();
_sprite.x = 0;
_sprite.y = 100;
addChild(_sprite);
addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
public function onEnterFrame(event:Event):void
{
_sprite.x = 200 + Math.sin(_angle) * _xRadius;
_sprite.y = 200 + Math.cos(_angle) * _yRadius;
_ax += .01;
_angle += _ax;
}
}
}
수학적 머리가 나빠서 힘드네요 하악.
하고싶은건 이게 아닌데;ㅁ;
