Best Bone

Hello, guys i want to share with u my method of finding the nearest bone to the crosshair.

Code:

void bonesort(float arrayforsort[])
{
	int i, j;
	int buffer;
	for (i = 0; i < 8; i++) {
		for (j = 8 - 1; j > i; j--) {
			if (arrayforsort[j - 1]>arrayforsort[j]) {
				buffer = arrayforsort[j - 1];
				arrayforsort[j - 1] = arrayforsort[j];
				arrayforsort[j] = buffer;
			}
		}
	}
}

Vector Best(int target)
{
	Vector MyAnglePosition, HeadAngle, StomachAngle, NeckAngle, ChestAngle, LLegAngle, RLegAngle, LFAngle, RFAngle;
	MyAnglePosition = Player.AnglePosition + Player.Position;
	
	CalcAngle(MyAnglePosition, EntityList[target].HeadPosition, HeadAngle);
	CalcAngle(MyAnglePosition, EntityList[target].StomachPosition, StomachAngle);
	CalcAngle(MyAnglePosition, EntityList[target].NeckPosition, NeckAngle);
	CalcAngle(MyAnglePosition, EntityList[target].ChestPosition, ChestAngle);
	CalcAngle(MyAnglePosition, EntityList[target].LeftLegPosition, LLegAngle);
	CalcAngle(MyAnglePosition, EntityList[target].RightLegPosition, RLegAngle);
	CalcAngle(MyAnglePosition, EntityList[target].LeftFootPosition, LFAngle);
	CalcAngle(MyAnglePosition, EntityList[target].RightFootPosition, RFAngle);

	Vector HeadDelta, StomachDelta, NeckDelta, ChestDelta, LLegDelta, RLegDelta, LFDelta, RFDelta;
	HeadDelta = HeadAngle - Player.CurrentViewAngles;

	ChestDelta = ChestAngle - Player.CurrentViewAngles;
	LLegDelta = LLegAngle - Player.CurrentViewAngles;
	RLegDelta = RLegAngle - Player.CurrentViewAngles;
	LFDelta = LFAngle - Player.CurrentViewAngles;
	RFDelta = RFAngle - Player.CurrentViewAngles;

	float Head_fov, Stomach_fov, Neck_fov, Chest_fov, LLeg_fov, RLeg_fov, LF_fov, RF_fov;
	Head_fov = sqrt(powf(HeadDelta.x, 2) + powf(HeadDelta.y, 2));
	Stomach_fov = sqrt(powf(StomachDelta.x, 2) + powf(StomachDelta.y, 2));
	Neck_fov = sqrt(powf(NeckDelta.x, 2) + powf(NeckDelta.y, 2));
	Chest_fov = sqrt(powf(ChestDelta.x, 2) + powf(ChestDelta.y, 2));
	LLeg_fov = sqrt(powf(LLegDelta.x, 2) + powf(LLegDelta.y, 2));
	RLeg_fov = sqrt(powf(RLegDelta.x, 2) + powf(RLegDelta.y, 2));
	LF_fov = sqrt(powf(LFDelta.x, 2) + powf(LFDelta.y, 2));
	RF_fov = sqrt(powf(RFDelta.x, 2) + powf(RFDelta.y, 2));

	const int size = 8;
	float massive[size] = { Head_fov, Stomach_fov, Neck_fov, Chest_fov, LLeg_fov, RLeg_fov, LF_fov, RF_fov };
	bonesort(massive);

	if (massive[0] == Head_fov)
		return HeadAngle;
	if (massive[0] == Stomach_fov)
		return StomachAngle;
	if (massive[0] == Neck_fov)
		return NeckAngle;

	if (massive[0] == LF_fov)
		return LFAngle;
	if (massive[0] == RF_fov)
		return RFAngle;
