Flappy Bird in C# by using Microsoft Visual Studio 2010.

1. FLAPPY BIRD GAME
By: Hamza Gulistan
Reg no: FA14-Bcs-027

2. Introduction
• It is a simple game in which one bird is moving between
different obstacles.
• If the bird touches any obstacle then the game will be end
and the total score will show on the screen.
• Every time the bird crosses any obstacle the score
increases by 1.

3. Creating a Flappy Bird game in Visual
Studio Using C#
• Create Windows Form Application
• 4 Picture boxes,
• 1 Timer Object
• 4 Labels

4. Naming
Name Text Property
PictureBox1 flappyBird
PictureBox2 pipeTop
PictureBox3 pipeBottom
PictureBox4 ground
label1
label2
label3
label4
scoreText
endText1
endText2
gameDesigner
timer1 gameTimer

6. Coding
the core variables for the game
bool jumping = false;
Int pipeSpeed = 5;
int gravity = 5;
Int Inscore = 0;

7. Set the label properties
• endText1.Text = "Game Over!";
• endText2.Text = "Your final score is: " + Inscore;
• gameDesigner.Text = "Game Designed By your name
here";
• endText1.Visible = false;
• endText2.Visible = false;
• gameDesigner.Visible = false;

8. Functions
• We need 3 functions that will be triggered by various
events
• 1) Timer function
• 2) keydown function
• 3) key up function
• 4) game end function

9. Adding timer properties:
name = gameTimer
Enabled = True
Interval = 15

10. gameTimer_Tick function
pipeBottom.Left -= pipeSpeed;
pipeTop.Left -= pipeSpeed;
flappyBird.Top += gravity;
scoreText.Text = " " + Inscore; //for scores
This will scroll the pipes to the left and drop the bird using
the gravity variable.

11. The bounds property
• Ending game
• Bounds check for height and width of each of the picture
box. Intersects with will check the height and width of
another picture against the first one and check to see if
they are colliding.

12. Enter the following code in the timer
function
if (flappyBird.Bounds.IntersectsWith(ground.Bounds))
{
endGame();
}
elseif (flappyBird.Bounds.IntersectsWith(pipeBottom.Bounds))
{
endGame();
}
elseif (flappyBird.Bounds.IntersectsWith(pipeTop.Bounds))
{
endGame();
}
gameTimer.Stop();

13. Regenerating pipes
Enter the following code in the game timer function
if (pipeBottom.Left< -80)
{
pipeBottom.Left = 1000;
Inscore += 1; //score add
}
elseif (pipeTop.Left< -95)
{
pipeTop.Left = 1100;
Inscore += 1; //score add
}
The code above checks whether the pipes have left the screen
and gone beyond -80px to the left.

14. score on screen
scoreText.Text = “ " + Inscore;

15. Code of key down function & keyUp
• this will reverse the gravity and make the character jump.
if (e.KeyCode == Keys.Space)
{
jumping = true;
gravity = -7;
}
• Enter the following code in the key up function, this will enable
gravity again to the character
if (e.KeyCode == Keys.Space)
{
jumping = false;
gravity = 5;
}

16. endGame()
• create a function to be used when we want to the end the
game.
private void endGame()
{
gameTimer.Stop();
endText1.Visible = true;
endText2.Visible = true;
gameDesigner.Visible = true;
}

}

18. private void gameTimer_Tick(object sender, EventArgs e)
{
pipeBottom.Left -= pipeSpeed;
pipeTop.Left -= pipeSpeed;
flappyBird.Top += gravity;
scoreText.Text = " " + Inscore;
if (pipeBottom.Left < -50) //ending game
{

}

}
