Circle to Circle collision, checking each circle against all others
- by user14861
I'm currently coding a little circle to circle collision demo but I've got a little stuck. I think I currently have the code to detect collision but I'm not sure how to loop through my list of circles and check them off against one another.
Collision check code:
public static Vector2 GetIntersectionDepth(Circle a, Circle b)
{
float xValue = a.Center.X - b.Center.X;
float yValue = a.Center.Y - b.Center.Y;
Vector2 depth = Vector2.Zero;
float distance = Vector2.Distance(a.Center, b.Center);
if (a.Radius + b.Radius > distance)
{
float result = (a.Radius + b.Radius) - distance;
depth.X = (float)Math.Cos(result);
depth.Y = (float)Math.Sin(result);
}
return depth;
}
Loop through code:
Vector2 depth = Vector2.Zero;
for (int i = 0; i < bounds.Count; i++)
for (int j = i+1; j < bounds.Count; j++)
{
depth = CircleToCircleIntersection.GetIntersectionDepth(bounds[i], bounds[j]);
}
Clearly I'm a complete newbie, wondering if anyone can give any suggestions or point out my errors, thanks in advance. :)
