我正在寻找一个类来绘制六边形并旋转它,但我没有找到方法来定义中心上的旋转点。 谢谢。Hexagone旋转html5画布
function Hexagone (sides, size, centerX, centerY, rotation) {
this.sides = sides
this.size = size
this.centerX = centerX
this.centerY = centerY
this.rotation = rotation || 0
}
Hexagone.prototype.draw = function() {
ctx.beginPath()
// Reset transformation matrix
ctx.setTransform(1, 0, 0, 1, 0, 0);
ctx.translate(this.centerX, this.centerY)
ctx.rotate(this.rotation * Math.PI/180)
ctx.moveTo(this.centerX + this.size * Math.cos(0), this.centerY + this.size * Math.sin(0))
for (var i = 0; i <= this.sides; i++) {
ctx.lineTo(this.centerX + this.size * Math.cos(i * 2 * Math.PI/this.sides), this.centerY + this.size * Math.sin(i * 2 * Math.PI/this.sides))
}
//temp style
ctx.strokeStyle = "#000000"
ctx.lineWidth = 2
ctx.stroke()
}
非常正确......很高兴你能解决它!您应该发布您的答案(并在以后接受它),以便您的问题脱离“未答复”列表。 ;-) – markE
