Galaxial is a 2D space strategy game that features a sandbox mode allowing the player to explore, colonise and conquer planets in a vast randomly generated galaxy.

Some of the latest features I have been working on since the last development log.

Planet Population Graphics

Finished creating some additional planet graphics to show roughly how large the colony populations are. The graphics change based on the current colony population in relation to the maximum it can support.

It starts off with just the colony infrastructure visible where the facilities are built in the center. Then at 20%, 40%, 60% and 80% of the maximum population it will grow outwards an extra zone.


(Colony with population zone graphics)

The textures are very large (uses a lot of GPU memory) so I dont think it will be possible to make seperate versions for each faction with the same color customization system that is used for ships.

You can see a giant screenshot version here which shows how smooth everything looks in-game. (4096x4096 size image, 10MB)

Population Growth

There are many factors that affect the colony population growth rate including:

  • Colony happiness
  • Tax rate
  • Food surplus/shortage
  • Luxury resources
  • Researched technologies

I'm not sure yet whether you will be able to use passenger ships to move migrants between colonies, but am aiming to have the colonies take quite some time (in-game) to reach their maximum size through normal growth.

Fog of War

Did some experimenting with fog of war by making each ship have a limited view distance. (similar to most RTS games) I didnt think it looked quite right for Galaxial and was rather annoying not being able to see the whole battles taking place.

So I have decided to use a system where you only need a single ship in a sector to reveal the entire area, rather than revealing smaller areas around each individual ship.


(Previously explored sector now hidden by shroud)

Once you no longer have any ships or a colony in the sector, then it will become hidden again and covered by shroud. Asteroids, jumpgates, wreckage and the colony will remain partly visible based on what was there the last time it was visited. If you return after some time you may find it has changed or some things have disappeared.

I will most likely add a new specialized ship type that can be used for scouting and exploration. They will get a cloaking module bonus to help them remain hidden. Destroyer class ships will get bonuses to detecting the cloaked ships.

At the start of a game all sectors will be hidden on the galaxy map until they are explored.


(Explored sectors visible on galaxy map)

For the moment I have left all the background stars and glowing areas visible on the galaxy map from the start. It looks nice but think it will make it a lot easier to predict where everything is in relation to your starting position. So may have to hide more of the background stuff until the nearby sectors get explored...

Ship Modifiers

Made a few changes to some of the ship modifiers for balancing reasons and added some extra ones.

  • Energy Leech (Drains energy from target ship and adds to its own)
  • Energy Leech Resistance (Reduces effectiveness of energy leech modules)
  • Decelerator Resistance (Reduces effectiveness of decelerator modules which slow the ship)

There is now just one generic damage type rather than being seperated into explosive, electromagnetic, chemical types etc.. This is to make it simpler when designing ships and reduce the need to equip so many modules that add protection from individual damage types.

Added a stacking penalty for when you equip modules that affect the same attribute. This is to make it impossible to get really overpowered ship stats or becoming immune to damage.

How would radar work if you implement it?

Not quite sure what you mean. Theres already a minimap that shows objects in a sector, or do you mean something else? Detecting cloaked ships?
