JavaScript

Is there any function in canvas to be able to draw a line at an angle of the desired length?

Answer 1

function drawMyLine(x,y,angleDeg,length){//Угол в градусах
  var angle = angleDeg * Math.PI/180;
  ctx.beginPath();
  ctx.moveTo(x,y);
  ctx.lineTo(x + Math.cos(angle)*length,y + Math.sin(angle)*length);  
  ctx.stroke();
}
