This week we did a major design iteration on the planet colonisation system. In the previous design, the planet was split into a huge square grid and you could send scouts anywhere to find resources. Extractors were built on the resources and they were piped to the planet’s main colony for use, so if you found a mineral deposit you’d build a mining station on it and the colony would then have +1 minerals/turn for use in factories.
After some testing, I found that it felt like I wasn’t really colonising the planet; I was just exploring it because I had to get it out of the way, and that’s not fun. Since I could see the terrain and knew where resources would spawn, I tended to go straight for those areas and there wasn’t much left to find in the entire planet. There were also unanticipated problems with designing a reusable colony blueprint: How do you know how many fossil fuel power plants or factories to build if each planet has a different number of resources? And what happens if the blueprint finishes building all your factories but you haven’t found the minerals to supply them yet? This week’s design iteration solved all of the above problems. Read More
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
Made good progress on the combat system this week. It now has:
- Movement mechanics: Left click moves ship to the selected square, right click turns toward the selected square, end turn button cycles to next ship in initiative order
- A glowing line indicates the path ship will take to the square you have the mouse over
- A ghost ship shows where your ship will end up and what diredction it will be facing
- Ships smoothly animate along the selected movement path
- Ships now have weapons
- Weapon firing arcs are working and show on the grid when you activate the weapon
To see the system in action, check out the prototype video below. Please post any comments you have on it and I’ll use them to help refine the next iteration. Read More
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
I got to work on the planet exploration a bit more this week, and added in a lot of the planet exploration features I described last week. You can now queue up as many scout missions as you want and they will be executed in sequence. When a mission starts, it takes an energy cost from the planet’s reserves, and if that energy isn’t available the mission will wait until you have enough energy before starting. You can now delete scout missions, and they are now sent from the nearest settlement you own for reduced travel time. Below is a video showing some of the new mechanics: Read More
This week I’ve been working on a prototype of the planetary exploration feature discussed on the Colonisation page. The plan was to split each planet up into a grid, and then have the player survey squares to find out what’s there. Exploration only needs to be done once for every planet, and it’s the only way to find resources or increase a planet’s maximum population. The idea is that every time you colonise a new world you’ll explore it and decide how to capitalise on what you’ve found. You might find the planet has a lot of ore deposits, for example, and build extra factories to take advantage of it. Or you might find ancient ruins to build research outposts on, or a uranium deposit that would let you put up a nuclear power plant.
As you progress in the game, you’ll get technologies that make scanning a planet faster and easier, like scanning tech that can spend reserve energy to scan a square, several squares, or a full screen instantly. Ultimately, you’d get the tech to automatically scan all planets from orbit so that when you’re in the late game war stages you don’t have to deal with the micromanagement of exploring new planets. Below is a video of the current gameplay prototype of this exploration system (using massive placeholder models for ore deposits etc). Watch in 1080p fullscreen if possible: Read More
Every 4X game has a way to notify the player when something happens that requires his attention. Games will typically have a turn summary page reporting anything important, but I want a more direct visual notification that isn’t just a text list. The idea I’ve been prototyping this week is a taskbar that runs along the bottom of the screen and alerts the user to tasks that require their attention. If a planet has a building that needs to be placed or a problem that needs to be fixed, or if a discovery is made or a scout finishes surveying a planet etc, a small icon relating to the event will drop down into the task bar. When clicked, a window would open explaining the notification and with a shortcut button to go directly to the screen/window that will let you deal with whatever the notification is for. Either that or clicking the icon might bring you straight to the source of the notification.
For example, you could start building a colony ship and check a box that says you want to be notified when it’s complete. When it’s built, a little ship icon would drop down and land in the task bar. On clicking the icon, a small ship/fleet window would open and you could immediately give the ship orders. Similarly, if a survey mission on a planet completes, a notification could immediately appear in the taskbar and open the planet or solar system when clicked.
I got some great feedback on what type of system window to use, and have decided that a small self-contained window is the best option. This week I developed a modular window system that keeps track of all the windows that are open and has options to resize, close and minimise to the taskbar. The game now supports having multiple system windows open, which might be handy if you need to keep track of or compare multiple systems. The video below demonstrates both the modular window and taskbar system: Read More
I’ve tried out two different schemes for the system view: A small separate system window with evenly spaced planets like in MOO2, and a fullscreen version with more realistic full solar systems. I promise that I would put up a video of both to collect feedback, so below is a video with examples of each: Read More
I’d like to thank Adam at SpaceSector for his awesome introduction post on Predestination. I’ve been a bit quiet this week, but have been working on the project. We’re getting forums and a website set up, and making progress on the trailer for the kickstarter campaign. I’ve also been putting together a few videos to show off various parts of the game. Below is a preview of the planet graphics in the game: Read More
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
