示例1: GetSideCollisions
private IEnumerable<CollisionEvent> GetSideCollisions(IBody movingBody, Direction movingSideDirection, Vector2 path)
{
var axis = movingSideDirection.ToAxis();
var sidePosition = movingBody.GetBound(movingSideDirection);
var counterDirection = movingSideDirection.AtBack();
var pathForward = path.GetComponent(movingSideDirection);
if (pathForward == 0)
return Enumerable.Empty<CollisionEvent>();
var pathStartInclusive = pathForward > 0;
var pathEndInclusive = pathForward < 0;
var pathLeft = path.GetComponent(movingSideDirection.AtLeft());
var sideStartInclusive = pathLeft < 0;
var sideEndInclusive = pathLeft > 0;
var pathAlong = path.GetComponent(axis);
var pathAcross = path.GetComponent(axis.Orthogonal());
var collisionType = pathForward >= 0 ? CollisionType.Entering : CollisionType.Leaving;
var incidenceTangent = pathLeft/pathForward; //todo maybe pathLeft negate....
var movedSidePositionRange = new Range(sidePosition, pathStartInclusive, sidePosition + pathAlong, pathEndInclusive);
var movedSideRange = movingBody.GetBoundRange(movingSideDirection, sideStartInclusive, sideEndInclusive);
var counterSides = _sideRepository.GetSides(counterDirection, movedSidePositionRange, movedSideRange, pathAlong > 0);
