Planet exploration update and terraforming idea

The Predestination team gained three new members this week: a new concept artist, a 3d modeller and a composer have officially joined the crew. The artists have been working on  new animated buildings for the colony screen this week, and our composer has been producing some awesome sci-fi music for the game. I’ll properly introduce the new and current members of the team in my next update and can hopefully show you some of their handiwork soon.

This week we’ve been working on fleshing out the designs for the races we plan to have at launch, and I’ve been implementing a hex-based planet exploration system to go with the hexagonal colony system described in the previous update. Players now have to explore outward from the starting colony as you can only explore hexes on the border with unexplored areas. Exploring a tile reveals what’s on that tile (if anything) and pushes your borders back, letting you see what all the surrounding squares look like. Below is a screenshot of the new system in action: Read More

Nebulae and asteroids in ship combat

I haven’t posted an update in a while, but rest assured I’ve been making a lot of progress on ship combat system. Ships now have armour, regenerating shields, structure hitpoints and weapons; they can shoot at each other and destroy each other. I’ve also implemented the reactive strike system that lets ships fire when an enemy flies through their firing arcs and players can hit a button to highlight all the squares the enemy’s reactive strikes cover so you can make tactical decisions quickly. There are firing animations for beam weapons and projectile weapons, which I’ll put a video up of once I’ve built the hotbar user interface to show it off properly. Below is what I’ve been working on this week: Read More

Fleet combat hex system first prototype

This week I’ve been working on the fleet combat system for Predestination. When all of the core mechanics are implemented, we’ll be releasing this as our first beta test to get some feedback and improve it. Fleet combat is an important part of a 4X game, and it will have to be iterated on extensively to make it as awesome as possible. Our goal is to create tactical turn-based combat system that’s more like a game of chess than an RTS. We’ve already tested the movement and combat mechanics with a pen-and-paper prototype, and this week I started putting it all in code.

It doesn’t look very pretty yet, but I want to show you what I’ve got so far. I’ve finished the hex grid system and ships can be placed on the grid and rotated to face any of the adjacent hexagons. All ships involved in the combat roll initiative and then take their turns in order. For moving ships, I developed an efficient recursive algorithm that determines the shortest route to a hexagon based on the three simple rules below:

  • Moving into any of the three forward squares costs 1 move point
  • Turning by 60 degrees costs 1 move point.
  • Two ships cannot occupy the same square

The result produced the exact pattern that my prototype design predicted: Read More

Second iteration on planet exploration system

There are lots of software development strategies, but the one that comes naturally to me is rough iterative development. The process starts with an idea for a feature, which is then used to produce a gameplay prototype. I try the prototype out to see how it feels, and show it to people to collect feedback. That feedback is used to refine the prototype into a second iteration, which is then tested and shown to people again to collect feedback. This cycle continues until eventually I’m happy with the feature. Usually I do all the testing myself and only show the prototypes to a few real life friends, but over the past few weeks I’ve been showing the prototypes to people via the blog. Even with just a few people commenting, it’s been really useful.

Last week I showed a gameplay prototype of the planet exploration system and got some great feedback. This week I’m back with the second iteration on that system: Read More

Head-tracking in Predestination, for a 3D perspective without expensive equipment

This week I’m working hard on putting together a Kickstarter campaign so I haven’t had much time to work on gameplay. But I wanted to show off an exciting development this week: Head-tracking.

Remember the video below from a few years back? In it, Johnny Lee showed off his awesome head tracking demo for games using a Wiimote connected to his PC. It turns a monitor or TV into a portal into a virtual room that visually reacts to movement exactly as viewing a real 3D box through a window would. Objects can even be seen to float out in front of the screen, providing a real 3D experience without the need for an expensive 3D monitor. In fact, all you need to pull this off is a Wiimote and a cheap pair of safety glasses with infra red LEDs in them. Read More

An example of the playable galaxy map screen when it’s generated in 2D. It would also be possible to generate the map in 3D and then flatten it to 2D, this shouldn’t cause overlapping stars but might make the distances between stars unintuitive. Read More

Galaxy map and screen transitions

One of the challenges in developing a space 4X game is that the game has to be played on the colony, solar system and galaxy levels. Master of Orion II had separate galaxy map and colony management screens, and the solar system view was a small window that opened inside the galaxy screen. This was handy because sometimes you’d exit out from a planet and want to fast-forward a few turns before returning to that planet. I like this functionality, and want to preserve it in Predestination.

This means I need separate galaxy and colony views, which I can already do with my GalaxyScreen and PlanetScreen. These are distinct screens that can be switched between instantly, but I need to build a visually smooth transition between them. On selecting a planet, I’d like the game to zoom in on the planet before switching to the PlanetScreen so that the two screens look identical and you don’t notice the transition. I also need a solar system window that can be brought up in GalaxyScreen. Read More
