Checking Mouse Directions in Windows Form Application, Step by Step

Mouse Directions in Windows Form:

We can check the mouse directions on Windows Form Application using the events of mouse_move on the Win Form. For example we want to check that in which direction the mouse is moving in our Application such as a game like subway surfer.

 Here we will learn how to check the movement Directions of a mouse in Windows Form App using C#.

Following are the Steps:

• First of all open the Windows Form Application is C#, and add a label and place it in middle of the Form like picture below.

• Write the following code in Form1.cs Class:

Code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication3

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        int cnt = 0;  // i am taking this as i want to run a code only for the first time

        int my_x, my_y;  // we will store the mouse position (x axis, y axis) in these variables

        private void Form1_MouseMove(object sender, MouseEventArgs e)

        {

            if (cnt == 0) // we have already taken cnt as 0 

            {

                my_x = e.X;   // storing current x axis location of mouse pointer on Form

                my_y = e.Y;    // storing current y axis location of mouse pointer on Form

                cnt = 1;   // we want to run above code only for first time, so we are changing cnt value

            }

            Text = e.X.ToString() + ',' + e.Y.ToString();  // this will show on the top of Form 

            if (e.X > my_x )    // if x axis is increasing and greater than previous stored x-axis, means mouse moving to right

            {

                label1.Text = "right".ToString();

                my_x = e.X;  // storing new location as my_x 

                my_y = e.Y;   // Storing new location

            }

            if (e.X < my_x)   // if x axis is decreasing and less than previous stored x-axis, means mouse moving to left

            {

                label1.Text = "left".ToString();

                my_x = e.X;   // Storing new location

                my_y = e.Y;  // Storing new location 

            }

            if (e.Y < my_y)  // if y axis is decreasing and less than previous stored y-axis, means mouse moving to up

            {

                label1.Text = "up".ToString();

                my_y = e.Y;    // Storing new location   

                my_x = e.X;   // Storing new location 

            }

            if (e.Y > my_y)  // if y axis in increasing and greater than previous stored y-axis, means mouse moving to down

            {

                label1.Text = "down".ToString();

                my_y = e.Y;  // Storing new location

                my_x = e.X;  // Storing new location

            }           

        }

    }

}

Output:
