How to convert game object world position to hex grid cell coordinates?

So basically what i want to do is simple, i have a hex grid and a game object let’s say it’s the player, what i want to do is know on wich cell the player is on based on his world position, this would be easy on a simple grid but on a hex grid its giving me a headach, if anyone can give me an approache to this it would be very much appreciated thank you.

public Vector2 GetHex(Vector3 point)
int column;
int row;

		// Find out which major row and column we are on:
		row = (int)(point.z / 0.87f);
		column = (int)(point.x / (radius + radius/2));
		// Compute the offset into these row and column:
		float dz = point.z - (float)row * 0.87f;
		float dx = point.x - (float)column * (radius + radius/2);
		// Are we on the left of the hexagon edge, or on the right?
		if (((row ^ column) & 1) == 0) {
			dz = 0.87f - dz;
		int right = dz * (radius - radius/2) < 0.87f * (dx - radius/2) ? 1 : 0;
		// Now we have all the information we need, just fine-tune row and column.
		row += (column ^ row ^ right) & 1;
		column += right;
		return new Vector2(Mathf.RoundToInt(column), Mathf.RoundToInt(row / 2));
