proper main window, message boxes (except pausing game) and blank board: 4 points

Windows Forms part 2

Example solution




Custom background

Asteroids and spaceship drawn with supplied graphics

Board has Context Menu (right- click) with 2 options - 'Ennable immortality' and 'Disable immortality'

Top menu

New item 'Window' with two children - 'Background' and 'Reset'

'Background' stops the game and shows file dialog with filters for Image files and custom title

Chosen file becomes background of board - it is stretched to size of board

'Reset' resets background to default

Bottom menu strip with information about time in seconds

Game board

space ship moved by pressing arrow keys but now pressing an arrow accelerates or decelerates spaceship in proper direction

both asteroids and spaceship can fly over one edge of the board and appear on the other edge (they should slide through edge)

when immortality is enabled spaceship don't interact with asteroids

when immortality is disabled collision of spaceship and asteroids can occur and then message box is shown with information of how long player played

Additional constrains:

In this part 'drawing' with controls is FORBIDDEN one has to use proper drawing methods of Graphics object

There is no visible flickering (use double buffering)

all functionality of part one should be present

when all windows, message boxes and context menu are shown game should pause

when player dies the message box shows 'GAME OVER' title and information with time of game

after 'GAME OVER' massage box, new game is started with enabled immortality, timer reset


Open file dialog

Context menu strip

Simple drawing with GDI:

Step 1: Load proper bitmap from file:

Image bmp = new Bitmap("[url removed, login to view]");

Step 2: Put PictureBox control named 'box' on form.

Step 3: Draw with 'bmp' on 'box' using double buffering:

Image buf = (Image)[url removed, login to view]();

using (Graphics g = [url removed, login to view](buf))


[url removed, login to view](Black);

[url removed, login to view](bmp, 0, 0);


[url removed, login to view] = buf;

Above sample code will make picureBox black and draw [url removed, login to view] picture in left up corner.
