Hello,
new guy here,
I need help with my code, i'm helpless right now now.

i have my 2D isometric map working but, when i want to implemet mouse selection on each tile it calculates wrong
with a help from : https://gamedevelopment.tutsplus.com/tutorials/creating-isometric-worlds-a-primer-for-game-developers--gamedev-6511

mouse calc Code:

public void handleMouse(GameMouse mouse, Camera camera)
{
    mousePosition = mouse.state.Position;

    Point tile = mousePosition;
    tile.X += camera.xOffset;
    tile.Y += camera.yOffset;
    pointingAt = getTileCoordinates(tile);
    int temp = 0;
    if (pointingAt.X < 0)
    {
        temp = pointingAt.X;
        pointingAt.X = pointingAt.Y;
        pointingAt.Y = -temp;
    }
    if (pointingAt.Y < 0)
    {
        temp = pointingAt.Y;
        pointingAt.Y = pointingAt.X;
        pointingAt.X = -temp;
    }

}

public Point getTileCoordinates(Point pt){
    Point tempPt = new Point(0, 0);
        tempPt.X = (int)Math.Floor((decimal)pt.X / (decimal)(tileHeight / 2+32));
        tempPt.Y = (int)Math.Floor((decimal)pt.Y / (decimal)(tileHeight / 2+32));
     return(tempPt);
}

and than i just draw basic tile on top of tile that exists:

Tile selectTile = tiles.Find(selectedTile => selectedTile.positionNumber.X == (float)pointingAt.X && selectedTile.positionNumber.Y == (float)pointingAt.Y);
                if(selectTile != null) { 
                    int x1 = (int)selectTile.positionNumber.X * tileWidth / 2;
                    int y1 = (int)selectTile.positionNumber.Y * tileHeight / 2;

                    int ix1 = x1 - y1;
                    int iy1 = (x1 + y1) / 2;
                    Point isoCoords1 = new Point(ix1, iy1);
                    isoCoords1.X -= camera.xOffset;
                    isoCoords1.Y -= camera.yOffset;
                    isoCoords1.Y += 48;

                    Texture2D renderTexture1 = textureList.Find(texture => texture.type.Equals("basic") && texture.id == 999).getTexture2D();
                    selectTile.drawTile(isoCoords1, renderTexture1, tileWidth, tileHeight/2);
                }

when i run the game i'm getting this:

anyone have an idea how to aproach this ?
i will upload full code to GitHub
in zip on github here:
