Create a 2D game in C++ using OpenGL (University Project)

You are to build a simple 2D game in OpenGL by using the GLUT toolkit to assist you. The game is loosely based on the classic 80s game ‘Asteroids’. A partial version of the game screen is shown in figure 1 below. The game may be extended into 3D for coursework 2. The game scenario consists of a spacecraft in the centre of the screen. The ‘asteroids’ appear at the start of the game and the spacecraft can turn freely about its axis and fire missiles at the asteroids. The asteroids themselves do not translate but rotate slowly about their axis. If a missile fired from the ship strikes an asteroid, the asteroid disappears and the score is increased by 10 points. Once all the asteroids have been hit, then a new set of asteroids should be redrawn randomly1 on the screen but not drawn in the position where the ship is (you need to apply some simple collision detection there). The number and shape of the asteroids is up to you but there should be a minimum of 8 and they should vary in size and rotational speeds (smaller rotate faster). The game goes on indefinitely but feel free to put in a pause or stop. Every 10 seconds an alien spaceship (of your chosen design but should be small and hard to hit) should move into the scene and fire missiles at your spacecraft. If the spacecraft is hit 3 times then it disappears and the score is set to zero. The game restarts from the beginning with the spacecraft reappearing.. If the alien ship is hit once it disappears and the score is increased by 20 points. 1 Note: Pre-determined positions (at least 8 different positions for each asteroid is also acceptable but scores less marks). Random generation will score 5% more in this [login to view URL] 3D Graphics Programming – Coursework One version 2.0 - 2014 3 The star field behind the main scene should drift slowly2 from top to bottom or left to right with new stars appearing from the top/left as the old stars disappears from the bottom/right. Note that the star drift should be smooth and not jerky. Figure 1 Screen of incomplete version (asteroids can be filled (GL_POYGON) or line drawn (GL_LINES) ) Technical Details The screen consists of several objects: 2 Static (non moving) starts are acceptable but will score less marks – see mark [login to view URL] 3D Graphics Programming – Coursework One version 2.0 - 2014 4 a) Rotating spaceship (controlled by left/right arrow keys and fire using key of your choice) b) Asteroids (Hexagons are shown here but can be any shape you choose) c) Moving star field d) The ship e) The missiles from ship f) The score panel g) An alien spaceship that shoots at the ship in the centre Notes: All the shapes in the figure are built from simple primitives and you are free to copy this design without penalty or you can create your own shapes. The stars can be drawn by using points (GL_POINT) and smoothed, note that you can change the size of a point with an OpenGL command. Note you can use a mix of colours to give the impression of texture on the asteroids and ship. In coursework 2 we will use lighting to achieve this effect but for this coursework use different colour vertices. Deliverable for coursework one: 1. Spacecraft rotation code – model and rotation code (5% for model and 10% for rotation code and user controls) and working collision detection 15% 2. Moving star field (5% only if static) – 10% 3. Alien ship (motion/missiles/spawning) – 10% 4. Spinning asteroid model– 10% 5. Asteroid random or predetermined redraw code with working collision detection – 20% 6. Working Score panel – 15% 7. Collision detection – 10% 8. Explanation of code/3D graphics in the viva3 – 10% (Included in these are marks for coding standard and code quality)
