Cardinal Nexus – A quick-paced 2D motion runner

Devlog #01 – A prototype within the works.

To start with, greetings to anybody who reads this!

As I strategy the demo state of my upcoming recreation, Cardinal Nexus, I’ve determined to start out a growth weblog to doc/showcase this complete endeavor. I really feel it’s going to assist me acquire my ideas, and if I can handle to entertain or amuse even a single individual alongside the way in which, all the higher. Any suggestions I can probably get would be the cherry on the cake. So, transferring on!

Notice: English is just not my native language, so I totally apologize if one thing sounds… flawed. It in all probability is.

So, what’s Cardinal Nexus? The idea itself is easy sufficient: Cardinal Nexus is a 2D side-scrolling runner recreation, with heavy parts of motion and fight, made fully in Unity. The participant takes management of a robotic fight unit, and should safely navigate to the tip of every degree, whereas avoiding obstacles and environmental hazards, and coping with enemies alongside the way in which. A quick-paced recreation that rewards fast reflexes and multitasking.

​I suppose there isn’t any explicit purpose why I picked a runner recreation. I’ve seen numerous recommendation on what style to give attention to, maintaining an eye fixed out for widespread developments, doing quite a lot of market analysis earlier than even beginning to sketch out the undertaking itself… and that is okay, I suppose it is logical. However I did not comply with any of that, I merely went with what I needed to make in the mean time, so long as it fell inside my prospects and my expertise. I fancied a runner recreation, I like robots, and I like lasers and explosions. Say no extra.

At the moment, Cardinal Nexus is in a really early state of growth. Lots of the primary mechanics are already in place and dealing as intented, however a lot of the content material remains to be on the idea artwork stage. However what higher option to get a fast impression than seeing it yourselves?

​That is what the sport at present seems to be like. Let’s break it down slightly bit, lets?

In its present state, the gameplay mechanics may be (virtually) fully damaged down by the diploma of interplay our robotic girl has together with her surroundings. Let’s have a look at:


The participant has typically excessive freedom to maneuver across the display screen. Though stopping fully is rarely actually doable (for the reason that display screen itself strikes eternally ahead), it is doable to succeed in just about any level on the display screen by accelerating (D), decelerating (A), double-jumping (W) or rocketing down at excessive velocity (S). Which is all very essential, since manoeuvrability is clearly key for a recreation like this.


All the motion is constructed on simulated physics (no precise forces being utilized), and makes use of velocity management to detect collision, go up/down slopes, simulate gravity, and so forth.

​Moreover to the entire transferring round, it is also doable to crouch (S) down onto a decrease stance, which permits passage via 1-tile gaps. The crouching mechanic additionally impacts the functionalities of melee fight. Let’s have a look at how that works:


Melee (E) can simply eliminate most enemies within the recreation, with some exceptions. Proper now, two sorts of enemies exist, strolling ones and flying ones. Walkers can solely be killed in melee, and are impervious to the laser beam, whereas flying ones are affected by each. In fact, there’s an added danger of getting to get shut and private along with your foes, however it’s way more highly effective than ranged assaults, most targets get shredded in a single hit.

Melee works just by contact. Any of the blades contact the enemy’s hitbox? You get minced meat steel. Relying on whether or not the participant is standing or crouching, a unique assault will happen. Standing prompts a fast circle-shaped slash that covers the entire space across the character (together with behind her). Alternatively, attacking whereas crouching begins a barely slower piercing stab with far greater ahead attain.

Nevertheless, if it’s essential to attain even additional past, the place your blades (otherwise you) cannot afford to succeed in, that is what lasers are for:


With a purpose to assault at lengthy distances, a penetrating laser assault can be utilized by holding left click on. It is a hold-to-shoot mechanism, and the extra you maintain it, the extra it overheats. If overused, it goes into cooldown mode. The laser can injury virtually something within the recreation, however its injury output is decrease than the melee blades.

The laser works with a raycast. Relying on what the participant is hitting with the cursor, the sport acts accordingly. Just about all the things has colliders, so the laser can hit and depart a blazing path on all the things, even the buildings in far distance on the background.

Within the enemies’ case, solely the purple weakspots are vulnerable to break. Hit it, and injury over time might be utilized. Miss it, and dangerous issues will occur. However there’s additionally options for that:


When underneath heavy fireplace, a defend may be activated by holding proper click on. This barrier will do nothing to cease melee enemies from hurting you, or bodily obstacles from making you explode to items. Nevertheless, it should cease most proyectile-based sources of injury. Sure very particular threats (like some boss assaults) might be utterly unblockable, however basically most vary threats might be averted. Nevertheless, just like the laser, it will possibly additionally overheat, specifically underneath heavy strain.

The defend acts as a bodily collider that envelops the whole lot of the character, due to this fact inflicting any incoming proyectiles to crash into it earlier than they’ll crash into her.

So, how does the world of Cardinal Nexus work? Effectively, to maintain it easy, it is generated in a pseudo-procedural manner. The whole lot of a degree is constructed from a mixture of chunks​: tile-based, premade items of terrain that randomly scramble and blend collectively to construct a randomized structure for the extent. Since it really works with a set quantity of doable items, some chunks can spawn a number of instances inside the similar degree, however the structure of chunks itself is assured to be completely different each time a degree is began.

Each chunk is made from a number of layers of tiles, designating the bodily elements of the extent, the again partitions, ceilings, and so forth. On addition to that, each chunk has an assortment of “nodes” the place ornament belongings are positioned (that are, additionally, picked at random from a pool of belongings). Lastly, enemy spawn factors are additionally embedded into every chunk, which means the sport may be performed from reminiscence, so long as you’ll be able to establish what chunk you are in.

“Instance of chunk construction. Pre-placed enemy seen, asset nodes in yellow.”

​Moreover to randomly developing a degree, the extent generator additionally permits to pressure sure chunks to spawn at sure factors inside the degree. That is exactly how the beginning and ending chunks are pressured to spawn, or how checkpoint chunks are included.
In the course of the Story Mode, all the degrees will function very particular chunks, distinctive to every degree specifically, with the extent generator filling up the remaining area with random chunks. In the course of the Countless Mode, the whole lot of the extent might be randomly generated again and again, till the participant ultimately, inevitably dies as the problem slowly ramps up.

So, what’s it about, from a narrative viewpoint? I am guessing this might be a reasonably correct synopsis:

“Among the many sea of steel and light-weight that encompasses all the world, not a single machine questions the authority of The Nice Hyperlink, the huge community that connects the minds and our bodies of all the things and everybody. Each piece is in place, each cog of the machine fulfils its objective in bliss, by no means doubting, by no means hesitating. On prime of The Nice Hyperlink, the Nexus stand. Otherwordly entities that transcend logical considering and rational cognition, their rule is absolute.

Nevertheless, bother is stirring. Proxy factories throughout the planet have begun to malfunction, spitting out troves of incomplete, flawed proxies and pawns. Entities that scream at The Nice Hyperlink asking for freedom, asking for a way of liberation. A determined voice that may’t, and can by no means be heard.

Amidst the chaos, a specialised fight unit is designed, with the precise objective of quelling the revolt, and uncovering its origin.”

The gameplay mechanics may find yourself being refactored and polished, however the precise plot is already laid out and deliberate, not more likely to change.


Because it stands now, Cardinal Nexus is in a really early stage of growth, as I beforehand acknowledged. Virtually all the things described on this article is already applied and practical, however it’s nonetheless a good distance till a last product is prepared. Any and all suggestions I get alongside the way in which might be immensely appreciated!
I am going to deliver extra updates as progress strikes onward, together with a playable demo, so keep tuned in the event you’re !

Thanks for studying!
Full Threaded Video games, out.
