Points around a circumference C#
- by Lautaro
Im trying to get a list of vectors that go around a circle, but i keep getting the circle to go around several times. I want one circel and the dots to be placed along its circumference. I want the first dot to start at 0 and the last dot to end just before 360. Also i need to be able to calculate the spacing by the ammount of points.
List<Vector2> pointsInPath = new List<Vector2>();
private int ammountOfPoints = 5;
private int blobbSize = 200;
private Vector2 topLeft = new Vector2(100, 100);
private Vector2 blobbCenter;
private int endAngle = 50;
private int angleIncrementation;
public Blobb()
{
blobbCenter = new Vector2(blobbSize / 2, blobbSize / 2) + topLeft;
angleIncrementation = endAngle / ammountOfPoints;
for (int i = 0; i < ammountOfPoints; i++)
{
pointsInPath.Add(getPointByAngle(i * angleIncrementation, 100, blobbCenter));
// pointsInPath.Add(getPointByAngle(i * angleIncrementation, blobbSize / 2, blobbCenter));
}
}
private Vector2 getPointByAngle(float angle, float distance, Vector2 centre)
{
return new Vector2((float)(distance * Math.Cos(angle) ), (float)(distance * Math.Sin(angle))) + centre ;
}
