StarSystem Lander

Today I am going to share my design of the game I am going to make during the coming days. As I already mentioned before in my previous post, I am learning some more Python and game programming at the same time. My plan is to make few small games before summer really starts and to learn at least a little bit of actual game programming. It is actually a sad thing, that they don’t teach game programming at the university, because it is fun. 🙂

The Idea

I am not planning to do anything very complicated and I didn’t come up with truly awesome idea for a small game. So, I will be programming a lunar lander clone, which I decided to call StarSystem lander. The idea is to land safely on a planet without destroying the spacecraft or running out of fuel. Those who don’t know the game can check out for example this youtube link:

My plan is to make a little nice graphics, although I actually think that the wireframe looks nice and nostalgic. I just want to learn to make nicer graphics, because that is the way games nowdays are like. I will not probably reach a cool looking level of drawing, but at least I am giving it a shot.


Okay, so the features for the game are supposed to be something like this.

  1. Movable spacecraft, that rotates 360 degrees
  2. Fuel meter showing how much fuel is left
  3. A High-score list according to with how little fuel and how fast the user can land the ship
  4. Different planets with different gravities (Moon, Earth, Mars, etc.)
  5. Graphics
  6. Some sounds (space is an empty place, so no music)

This is propable all the features that the game should have. If someone comes up with other good features, please let me know, so I could also try to add them. But these are something I will try to accomplish in the coming week or two.


When designing for the game, it is important to make some kind of sketches, graphs, etc., to shorten the actual development time. I draw a sketch of the game on pen and paper (that is really THE FASTEST way to prototype) while sitting on a morning train from Lappeenranta to Joensuu today. Because I don’t have a scanner at hand, I will make a paint sketch here to give an idea of how I see the game looking like.

This paint sketch looks very horrible, but hey, this is something I made up in a few minutes. The one I had drawn in my sketchpad looks a lot more nicer. (maybe I should have taken a picture of with a camera…. well, next time). All in all, I really have to admit it, I am no graphics artist, but hopefully I will manage with all these ”oh-so-hard” graphics 😛

The game objects

Now, to the actual part I am a little better – designing architecture of the software. Because I will be doing this in a prototyping way and not giving way too much thought on all the parts (the game is not that big, I can easily change things when needed, as long as I program it properly). So, the main components are SpaceShip, Level, LandingPad, Timer and FuelMeter. These are the pieces the game is made of (drawn on the screen). The game engine beneath is of course it’s own case, but I will now just document some ideas of the game parts.


This is propably the most complicated of the classes. The spaceship has location (where it is on the screen), speed (= how fast it is moving), direction (which way it is moving) and fuel (how much fuel is left).

The methods that the spaceship has are Rotate(direction), which turns the spaceship either left or right. Throttle(), which is used to gain more speed to the direction the spaceship is facing. Move() is used to actually move the spaceship on the screen (this is for drawing reasons, which I will explain about a little bit later). The three get functions are used to get the specified information of the spaceship (like the current location). Also there is a checkLanded() function inside the spaceship class, but this I might probably change to somewhere else later.


Level object will propably contain the picture of the ground (how it is formed) and also contains the gravity value of the planet in question.


LandingPad is an object that will be placed on top of the actual level. This way there is no need to program to the level object the location of the landing pad, but to have it as an individual object, that can be called to check if the ship has landed at correct place.


Timer is used to get the time how long the game has been running. It just displays the current time on the top-right corner of the screen.


FuelMeter displays the amount of fuel left. Every time the user Throttles with the spaceship a small portion of the fuel is used up. The fuel meter draws the current situation of the fuel on the right side of the screen, under (or next to) the Timer.

Next Time

I have now demonstrated a very short and brutal design of the game. As I will be programming more and more, I will probably change classes a little bit when needed, but my goal is to get something done quickly. My next post will be about programming the StarSystem Lander game. The coming weekend will be pretty busy day for me, because I will be participating in one seminary. Expect for the next update around next week. And please, feel free to leave comments.
