반경을 따라 원의 중심을 중심으로 한 텍스트

Question

기하학적 인 문제를 해결하는 데 도움을주십시오. 휠의 여러 섹터를 만듭니다. 이제 모든 부분에 원의 중심에서 가장자리까지 텍스트를 배치해야합니다. 그러나 어쨌든 모든 것이 엉망이됩니다. 여기

는 한 섹터의 클래스입니다 :

을 그리고 그 모든 바퀴 작성이다 : 당신의 TextField의가 필요 말할 것입니다, 그것을보고함으로써

sectorsNum = tarotAC.length; 
       for (var i:int = 0; i < sectorsNum; i++){ 
        var arcAngle:Number = - 1/sectorsNum; 
        var startAngle:Number = arcAngle*i; 
        var arc:Sector = new Sector(FlexGlobals.topLevelApplication.mode, 360/sectorsNum, 0, 0, stageW*0.1, stageW*0.5, startAngle, arcAngle, Number(sectorsNum - i), tarotAC.getItemAt(i).color, 1, tarotAC.getItemAt(i).datas, tarotAC.getItemAt(i).url); 

        con.addChild(arc); 
       } 

Answer 1

을 높이에 의해 위로 움직여 라. TextField는 위에서부터 작성되며 사용자가 지정한 좌표는 기준선에 더 잘 맞습니다. 어쩌면 TextField를 스프라이트에 넣고 TextField의 y를 높이로 설정 한 다음 텍스트 자체 대신 컨테이너를 조작 할 수 있습니다.

var container:Sprite = new Sprite(); 
container.addChild(myText); 
this.addChild(container); 
myText.y = -myText.height; 
textRotation(container, rot*(sectorsNum-value) - rot*0.5, centerX, centerY); 
//you should of course modify textRotation's first parameter type 
container.x = imageX1 + 0 * (imageX2 - imageX1); 
container.y = imageY1 + 0 * (imageY2 - imageY1);
