COVID-19 is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic.
The symptoms of COVID‑19 can vary but often include fever,[7] fatigue, cough, breathing difficulties, loss of smell, and loss of taste.[8][9][10] Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.[11][12] Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction).[13] Older people have a higher risk of developing severe symptoms. Some complications result in death. Some people continue to experience a range of effects (long COVID) for months or years after infection, and damage to organs has been observed.[14] Multi-year studies on the long-term effects are ongoing.[15]
COVID‑19 transmission occurs when infectious particles are breathed in or come into contact with the eyes, nose, or mouth. The risk is highest when people are in close proximity, but small airborne particles containing the virus can remain suspended in the air and travel over longer distances, particularly indoors. Transmission can also occur when people touch their eyes, nose, or mouth after touching surfaces or objects that have been contaminated by the virus. People remain contagious for up to 20 days and can spread the virus even if they do not develop symptoms.[16]
Testing methods for COVID-19 to detect the virus’s nucleic acid include real-time reverse transcription polymerase chain reaction (RT‑PCR),[17][18] transcription-mediated amplification,[17][18][19] and reverse transcription loop-mediated isothermal amplification (RT‑LAMP)[17][18] from a nasopharyngeal swab.[20]
Several COVID-19 vaccines have been approved and distributed in various countries, many of which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, use of face masks or coverings in public, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. While drugs have been developed to inhibit the virus, the primary treatment is still symptomatic, managing the disease through supportive care, isolation, and experimental measures.

Responsiveness. That buzz word that has all front end web developers nodding in agreement is the process of making sure your virtual product is rendered well and usable in all sizes from the phone to the cinema screen. By using one code base and adapting to different resolutions and aspect ratios, this makes our experiences fluid and suited to the device we’re using while keeping code maintainable and not branching off for every target. With the rise of Android and the many many different screen sizes, this also becomes an important factor in games.
There are a few ways developers have tackled this in the past, some are more effective than others. Letter-boxing is a common solution, centring the content with the best fit to keep the aspect ratio and just ignoring the unused areas of the screen. Stretching to fit is another option but things can get messy if you code for 4:3 and display at 16:9. The method I use is not bulletproof but has worked for the past few games I have developed with great success.
The method I use I call the “scaled stage with margins” and is exactly as it says on the tin. It may have a proper name somewhere but I haven’t found one yet.
The idea is that the stage is a defined size – for example I often use 1280px x 720px as this is a common mobile resolution. This gets scaled and centred using the same method as the letterbox idea. The main difference is that I then calculate the extents of the screen in app space and these previously unused sections become the margins. My app can extend into these margins in any way it wants. I store these margins and can access their sizes from any part of my application through my “viewport” class. I can immediately tell where the furthest visible left part of the screen is by using viewport.left and if I need the total width including margins I can use viewport.totalWidth.
The maths behind this is quite simple. First scale the stage to the size it needs to be to fit wholly on the screen without cropping any edges. This usually looks like:
container.scaleX = container.scaleY = Math.min( screenResolutionWidth / targetWidth, screenResolutionHeight / targetHeight );
Then centre the stage:
container.x = (screenResolutionWidth – (targetWidth * container.scaleX)) * 0.5;
container.y = (screenResolutionHeight – (targetHeight * container.scaleY)) * 0.5;
The margins are added by transforming the stage.x and stage.y into app space. This gives you a number which is much easier to work with when positioning things on the stage.
marginLeft = container.x / container.scaleX;
marginTop = container.y / container.scaleY;
marginBottom and marginRight are the same as the top and left one respectively as the stage is centred. Once we have this we can store some other numbers for convenience. The point (0,0) will be the top left of the actual stage as if there was letter-boxing and the margins are defined as below.
totalWidth = targetWidth + (2 * marginLeft);
totalHeight = targetHeight + (2 * marginRight);
left = -marginLeft.
right = targetWidth + marginLeft;
top = -marginTop;
bottom = targetHeight + marginTop;
There are many ways that this can be used. If I need a image that stretches to be full screen regardless of resolution. I can set it to x=viewport.left, y=viewport.top, width=totalWidth, height=totalHeight. Sorted. If I need something to stick to the top right I can set it to x = viewport.right – itemWidth, y = viewport.top. All that needs adding is a resize function that re-positions everything if the window is resized. It may not fix every solution but for many of the subtle differences in aspect ratio we see today this solution hits the nail on the head every time for me.
Some might argue that game design documents don’t work because they often get a bit of thought at the beginning of the project and then they never get read again – they can also easily go into too much detail and prevent progress being made at all.
I think GDDs should be an agile working document that can evolve and branch outside of the original document onto different platforms and forms. We don’t need to have everything in one ‘bible’. We just need to show our ideas and keep them moving, and more importantly make them accessible.
For us, starting out by writing a simple outline in google docs is really useful, and helps us to ‘initialize’ a project – but we don’t stop there! The following points below show of the key questions we ask ourselves when creating a GDD and some of the tools we use to evolve and maintain momentum of ideas.
Define and answer the 5 W’s – the Who, What, When, Where Why Hows. It doesn’t matter if you can’t answer all of these, just make sure by the end of answering, you have begun to split these out into headings you can see clearly.
Create game elements. Use tables and lists as often as you can, they’re easy to read and quick to scan.
Break down your document into checklists tools like Trello or My colleague, Rich has made a better version of google tasks that is really useful. Make sure the tasks are achiveable and don’t involve lots of sub tasks. Break these down into tasks too! Its easier to feel like the project is moving forward. You will be encouraged to stick at it and do more.
Allow for failiure – Don’t be too strict or unrealistic with your goals. Setting boundaries too high will only make you want to give up because its unachieveable. Talk to other people about why this particular point isn’t working – maybe you can get around t in another way?
We talk often and discuss what we like and don’t like about games. Most importantly, stay super enthusiastic about games and think about how other games work is the key to staying motivated.
A bit of a prologue:
An accurate description of how component systems are supposed to work is elusive as there are many varying opinions about how they are meant to be used. One thing is agreed, they are the way to go when developing large scale games.
The benefits of such a systems are undeniable. Imagine a game developed using object oriented (OOP) principles where each object is a defined type. Say for example we have a Vehicle class. We can extend this to be a Helicopter by adding flight functionality or we can extend this to become a Tank by adding armour and guns. What if we wanted to add guns to our Helicopter? Do we copy the code from Tank? Do we move the gun code up a level into Vehicle? Once more variations in design appear, our code gets cluttered, duplicated and misplaced. Entity component systems aim to extinguish this problem by breaking objects down to components.
Using the above example we would have a basic Entity (or GameObject as they are known in Unity). This basic object does nothing on its own except exist. We would then augment the Entity with abilities using Components. So, for example, our Tank would have a VehicleMovement component, an Armour component and a Gun component. Our Gunship will have Flight and Gun components. No duplication of code and no need to worry about the deadly diamond of doom.
Early research:
There are many ways to implement such a structure. Unity and Flambé use the approach where most of the logic happens in the components which are updated each frame. Flambé promotes components extending other components and each class that inherits directly from Component becomes a new component type. The problem with these is that inheritance creeps back in and before you know it, the habits drilled into us as object oriented programmers take over; we end up using components as the objects we are used to by piling logic into them an extending them to suit our needs.
…it’s all too easy for experienced OOP programmers to keep trying to sneak some OOP back in where it’s inappropriate, and it’s all too easy to delude yourself into thinking this is a Good Idea. And, worse, from the teams I’ve worked on in the past, it has consistently seemed that the better you are at OOP programming, the harder this is to resist… [Adam from T-machine.org]
Further to that, where does the logic go when when multiple components on the entity need to interact? Should one component be allowed to access another or should they be separated to keep dependencies to a minimum? What about in complex systems such as physics where multiple entities need to interact with each other? Where do we put this code? I’d been experimenting for so long I’d actually given up and started building my new adventure game prototype in a more traditional OOP way.
And then it clicked…
I’d got part way through before running into some basic inheritance issues and then it hit me; a component system doesn’t need to be the entire basis that a game is built on. Sprites don’t need to be components. UI and events don’t need to be components. Quite simply, the components are just another data model that enhances accessibility in game code and allows the game engine to pick and choose data it needs to work with. After reading guides to confirm what I thought, I knew I’d nailed it and finally got it straight in my head.
How it works for me:
I take my approach from this excellent guide by Adam from T-machine.
Think of the game as a database. We have Entities which are actually just ids to associate a group of components and nothing more. The most important thing to note is that they do not even need to exist as classes, objects, instances or anything of the kind. Once we simplify it down to this level of thinking we see that an entity component system is actually little more than an array of components, each associated with an entity id.
Components are data structures first and foremost. They are specific pieces of information attached to an “entity” and make up the identity of an object in game. Any part of my game can access any component just by querying the ComponentsSystem class. The entire job of the ComponentsSystem class is to store components and to retrieve them when given an entity id, a type of component or both. This means that my movement system can find all components defined as a movement type, and through the ComponentsSystem, find other components associated with an entity and adjust them as required. The code for my current component system is extremely simple; it’s only around 50 lines of code.
The second most important difference between a component system and OOP is where the logic goes. Instead of having objects that know how to handle themselves when given instructions, we instead have a collection of “dumb” data objects that know nothing but a few bits of information about themselves. This is where systems come in. As previously mentioned, the movement system in my game retrieves all components of the movement type. If an entity has no movement component then it’s not moving. The movement system takes the speed and direction from the movement component and applies it to the entity. It’s as simple as that. Because all of the logic is centralised, multiple entities can interact in the system’s code without explicitly knowing about each other keeping dependencies to a minimum.
This is the way I now understand component systems and I am using this methodology while building my latest game prototype. I have no doubt this new way of thinking will be beneficial to me as a new weapon in my coding arsenal and hopefully this brain dump will help others “click” in the way I did when trying for so long to understand entity component systems.
That got me thinking about the steps I took to make sure the game runs as smooth and as optimised as possible. On reflection, I think these are some really helpful tips that may be able to help others. Most of this advice has already been given elsewhere and some of it is just good practice but I think all of it is worth mentioning.
Use DrawTiles
This is a very Haxe/OpenFL specific method but it works; the benchmarks prove it. If drawTiles intimidates you then try other third party libraries that bridge the learning gap but still deliver on performance. I read somewhere that each call to drawTiles is the equivalent of drawing one bitmap to the screen. This brings me onto the next tip…
Sprite Sheets and Batch Rendering
As much as you can cram into one draw call, do it. Your graphics card will love you for it! As a result this means that you want to avoid swapping between source images as much as possible so try to pack everything into sprite sheets. Think about the order everything is drawn to the screen and arrange your sprite sheets accordingly. This Starling article (read from Painters Algorithm) sums up nicely how you should be arranging your sprite sheets. Once you have your sprites organised, render them in as few drawTiles calls as possible. Drop Dead Z probably has around 5-10 calls per frame to draw everything on the game screen. Rendering the whole game takes approximately the same time as rending 5-10 bitmaps. Smooth!
Object pooling
Creating and destroying objects takes time. When pressing play in Drop Dead Z for the first time in a session, you may notice that it pauses for a small moment while it builds the game in memory. That is fine. But if game objects are being created and destroyed throughout play, the game will slow down and sometimes become a little jerky while it thinks between frames. To get a full, stable 60fps you need to get all of your game logic done and your game rendered in less than 16ms. That’s about 25 times faster than it takes the average human to blink. If you can minimise object creation and garbage collection, you’re onto a winning formula. Drop Dead Z uses object pools so once a zombie is removed from play, it’s put to the back of the queue to be placed on the next building. No new zombies are created unless one is needed and the queue is empty. Even then, after they are created, they just join the cycle. Everything in the game works on this principle to keep object creation and garbage collection to a more manageable level.
Time based updates
If your game is running on less than ideal hardware, you can expect the frame rate to drop below your intended target. If your animations are done by moving an object a set amount each frame and the frame rate drops from 60fps down to 30fps, the object will move at half the speed. If the frame rate is unstable the game will look jerky and progress at varying speeds, making it frustrating and awkward to play. Basing your animations on time reduces this effect and can make games aimed at 60fps playable on less capable hardware. (Playable that is, not perfect.) Beyond doubt, even on high end devices, there will be things that make your frame rate unstable. Your phone my get a notification in the background, you may connect to a wireless network; it’s not all necessarily the fault of your code or even avoidable. What you can do is try to mitigate the effect on your game. By using time based animations, the amount an object moves is dependant on the time that’s passed between the current frame and the last. If processing a frame takes twice as long as it should then the game will skip forward keeping the flow of play consistent. Drop Dead Z uses time based animation for everything.
Separating game logic and rendering
If using the display list, this is usually done by the onEnterFrame loop; your code updates everything and then OpenFL / Flash renders everything. This is a useful tip to anyone using custom renderers – if your game uses some physics or collision detection that needs to be stepped multiple times per frame to prevent tunnelling, make sure you do all of this before rendering and don’t render anything until everything is in its final place. Only update the sections you need to update – there’s no point updating the animation code 5 times per frame if this doesn’t affect the physics. Drop Dead Z updates it’s physics in 16ms increments based on the amount of time that has passed. If rendering at 30fps the logic is still running at 60fps to keep everything working properly.
Tweened as opposed to frame-by-frame animations
I know this is not always possible but tweens can look miles better than frame-by-frame animations as the movement can be interpolated. The character from Drop Dead Z is built up of smaller static parts and these are tweened in a keyframe based animation. His animations will still look amazingly smooth in super slow motion because his movement can be split infinitely over time. This makes varying his running speed so much easier without eating up memory. Imagine having enough bitmap frames to make the player run smoothly in slow motion – he would need multiple sprite sheets of his own!
Avoid software rendering
In OpenFL, there are some things you can do that force the CPU to get involved with rendering your scene instead of leaving it to the GPU. If this happens then expect your game to crawl at about 5fps. Masks and filters are the usual culprits and there’s no easy way around this. If your filters can be applied once and cached then you should be OK but dynamic drop shadows are a big no. Rectangular masks can be simulated using scrollRect and this is enough for most uses but the easiest bet is just to design around the issue. Try and bake as many of your effects into your images as possible so your game has less to process at run time.
TL;DR
In summary, use drawTiles or the most optimised rendering method for your target platform. Try and reduce the amount of draw calls by batching as much as you can into each call. To do this use sprite sheets and be sure to optimise your asset organisation so images drawn consecutively come from the same sprite sheet. Use object pooling to reduce the time spent creating and destroying objects in memory. Always use time based animations as these are the most flexible and still work well even when not hitting your target frame rate. Finally avoid using masks and filters. Bake effects into your images and use scrollRect for rectangular masks.
I hope I have provided enough information here to be useful to others. There is probably plenty I’ve missed but the above worked well for Drop Dead Z and got us the “Smooth!” rating from Mr Elsass. If you haven’t played Drop Dead Z yet, you can get it on Android and Amazon. If you play it and like it please give us a good review.
Until next time,
