游戏中需要画扇形功能,纪录一下 == Graphics 画扇形 ==
代码
function test() {
this.Graphics.clear();
let r = 100 //半径
let startRadians = -0.25*Math.PI; //起始角度
let endRadian = 0.25*Math.PI;//结束角度
let start = cc.v2(100, 100); //圆心点
let point1 = cc.v2(Math.cos(startRadians)*r + start.x, Math.sin(startRadians)*r + start.y)
let point2 = cc.v2(Math.cos(endRadian)*r + start.x, Math.sin(endRadian)*r + start.y)
//画扇形的三角区域
this.Graphics.moveTo(start.x, start.y);
this.Graphics.lineTo(point1.x, point1.y);
this.Graphics.lineTo(point2.x, point2.y);
this.Graphics.lineTo(start.x, start.y);
//画扇形的圆弧区域
this.Graphics.arc(start.x, start.y, r, startRadians, endRadian, true)
this.Graphics.fill();
}
End
有其他更好的方法请留言,感谢

,thank
应该旋转的是 3点钟方向顺时针45度吗 但是现在填充位置不对
