пришлось залезть в библиотеку и переделать метод
теперь заработало
Query.ray = function(bodies, startPoint, endPoint, rayWidth) {
rayWidth = rayWidth || 1e-100;
var rayAngle = Vector.angle(startPoint, endPoint),
rayLength = Vector.magnitude(Vector.sub(startPoint, endPoint)),
rayX = (endPoint.x + startPoint.x) * 0.5,
rayY = (endPoint.y + startPoint.y) * 0.5,
ray = Bodies.rectangle(rayX, rayY, rayLength, rayWidth, { angle: rayAngle }),
collisions = Query.collides(ray, bodies);
for (var i = 0; i < collisions.length; i += 1) {
var collision = collisions[i];
collision.body = collision.bodyB //эту строку поправил, убрал bodyA
}
return collisions;
};
