Game Developer Deep Dives are an ongoing collection
with the purpose of shedding gentle on particular design, artwork, or technical
options inside a online game so as to present how seemingly easy,
elementary design choices aren’t actually that easy in any respect.

Earlier installments cowl subjects comparable to UI and issue ranges in Cook Serve Forever, the challenges of programming for 2D for Sweet Transit, physics-based animation in Gibbon: Beyond the Trees, and designing spatial inventories in darkish fishing sim Dredge. In this version, Jay Fernandes, director at Plastic Fern Studios,  discusses how the corporate designed and applied controls for the cellular port of PC and console title Descenders.

I’m Jay Fernandes, the director for Plastic Fern Studios, which is a completely distant recreation studio based in 2018. I’ve been within the video recreation trade for nearly 14 years and have labored on video games for cellular, to indie, to AAA and have (for nearly the previous 8 years) labored with many builders on porting, QA, launch administration, and even SFX or music. Some tasks I’ve been part of lately embrace Hades, Superliminal, SkateBIRD, Firewatch, the Playdate console, Escape Academy, and the cellular ports for Descenders (I in all probability have near 100 video games I’ve helped with in some capability at this level).

The most important contributors to the contact controls and the way they at present work have been:

Sunder Iyer — UI/UX Programmer for Plastic Fern Studios. Previously at AAA studios and labored on South Park The Fractured But Whole and The Sims 4. Came up with numerous enter schemes and produced mockups, paperwork, and iconography. Also playtested and offered suggestions together with Jay provided that each of us have UX backgrounds.

Bryan Alvarado – Friend of Jay’s for as very long time and Technical Director at 502 Studios, a recreation studio primarily based in Guatemala, engaged on video games and associated interactive fields for 10 years, releasing their very own video games and likewise collaborating with different firms and studios on their very own tasks. They have been just lately engaged on 502’s Arcade, their debut recreation for Steam and Nintendo Switch, and most just lately the cellular port of Descenders. He labored on refitting the UI, implementing controller help, integrating a number of the platform particular options, doing total bug fixing.

Oscar Morales — Generalist Programmer at 502 Studios. Before becoming a member of the corporate, he had been making unbiased video games and his final identified undertaking was Ultra Zultra. He’s additionally an organizer of GameDevGT, a Guatemalan recreation developer group. Worked on implementing the enter schemes and mockups in addition to optimizing the sport to suit the platform necessities and enhance efficiency.

Translating fast-paced controls to cellular

We have been fortunate sufficient to work on the iOS and Android port for the wonderful Descenders recreation which additionally included the challenges of making an attempt to make a recreation that works so properly on PC and Console really feel simply nearly as good on cellular. We knew there can be challenges because it wanted to carry out properly, have multiplayer, and was a fast-paced recreation that would have points translating to the touch controls or small screens, however by far the factor we spent probably the most time on was the controls and UX throughout gameplay. Luckily, with the assistance Sunder, and our buddies Bryan and Oscar from 502 Studios (Who helped immensely with the porting), we have been in a position to provide you with a brand new contact management scheme that felt pure, and matched with the quick paced enjoyable of the opposite platforms.

For these not acquainted with the sport, the sport contains a number of controls from acceleration/braking, steering, leaning, bending/pumping, and tons of tips so we knew from the start it will be an enormous problem to attempt to match every little thing on a contact display and nonetheless have it’s comprehensible, playable, and enjoyable (particularly for veterans who we requested for suggestions from all through the method to ensure it will “work”). It was crucial for us to make it possible for each new and superior gamers may carry out easy and complicated actions (particularly in more durable ranges) to match their playstyles.

We experimented with a number of completely different layouts. I imply rather a lot. Like much more than you’re considering. Gamepads’ bumpers and triggers (L and R buttons) current a problem when porting controls to the touch screens since usually you do not have these shoulder buttons and in lots of video games, these can modify the motion of the face buttons or analog sticks. A typical resolution to that is un-rolling the modification such that the mixed enter is introduced as a singular button on the contact display. This is appropriate in some video games the place a single motion may be modified into just one new motion however in our circumstances, Descenders‘ Trick button (RB, R1, R and so forth) may very well be mixed with the appropriate analog stick with carry out 8 completely different tips so unrolling a directional enter into 8 distinctive buttons would result in a cluttered on-screen UI.

An experimental button format that proved too advanced

Sunder performed with the thought of getting an additional on-screen touchstick for simply performing tips or having two contact spots for the appropriate touchstick such that one would provoke carving/tweaking whereas the opposite would carry out tips. He then proposed splitting the display into quadrants such that dragging in sure zones on the display would produce particular behaviors. 

A quadrant experiment that proved too complex

The quadrant experiment

The authentic proposal was to separate the display into 4 vertical slices, the left stick would solely work on 1st and 2nd slice which represented acceleration and braking and the appropriate stick would solely work on the third and 4th slice which represented trick and carving.

We went forwards and backwards a number of occasions and after playtesting and fine-tuning, we ultimately settled on a variation of this concept the place we had an on-screen zone for acceleration and one proper under it for braking. That stated, we additionally had a number of experimental approaches as properly, simply to see how they felt.

We tried different layouts like having the sticks speed up when pushed forwards and stopped when tilted again however it introduced some points when making an attempt to carry out higher-level maneuvers on harder programs (which, fact be informed I’m horrible at however fortunately testers and No More Robots may present us with skilled participant methods). A number of layouts additionally labored in idea however felt very completely different than the established recreation so we trashed them.

All of the designs technically “labored” (you could possibly management the sport with them, however some positively felt worse than others). This is the place our design and UX backgrounds in all probability got here within the strongest since we have been in a position to focus on with everybody what the objectives and wishes have been, have a look at the constraints of the platform, after which design and implement a management scheme to finest embrace every little thing and have gamers really feel like they’re enjoying one thing acquainted (particularly in the event that they’ve performed it earlier than) but in addition not really feel prefer it’s overly difficult to grasp. 

The final iteration of Descender's touch controls

The ultimate iteration of Descender’s contact controls on cellular

The hardest half was truly that a number of folks appreciated completely different layouts however we needed to finally resolve (and generally persuade) on what the cellular gamers would initially expertise. I believe a standard false impression with porting or creating for particular platforms is that simply determining “how” to make one thing work is the toughest half when a number of occasions it’s truly fairly simple to get a number of options working and the toughest half is deciding collectively which one is “finest.” We had a number of alternative ways to play the sport, however holistically a few of them have been only a dangerous match or would trigger points later for gamers, so we tried to acknowledge these issues (on high of common technical/growth points) to provide you with a contact management scheme that would do all the issues Descenders does so properly.

The resolution led to the present scheme, which incorporates the least quantity of components on display we may do (basically simply 2 joysticks) and nonetheless feels just like the precise recreation. Taking a posh moveset and making it work comfortably on touchscreen may be very troublesome and it will have 100 occasions simpler to provide you with a simplified contact scheme however then, the sport will not be Descenders, it will be one thing else. The ultimate scheme works one thing like this:

  • Two zones on the appropriate facet of the display which signify acceleration and braking – they are often visualized with a setting and can show inexperienced and pink overlays on high
  • You use the left contact stick on the left facet of the display to steer and lean
  • You use the appropriate contact stick to slip in addition to pump/counter-pump and bunny hop.
  • While within the air, the appropriate contact stick might be flicked in numerous instructions to do tips (this was the toughest factor to determine how get to work properly).
  • You may also transfer the appropriate contact stick on the appropriate facet of the display over the speed up and brake zones for finer management whereas carving/sliding.

In the top we predict it really works fairly properly and hopefully gamers get pleasure from it too! (in any other case, it additionally helps controllers!). Even although this was one in every of many issues solved in bringing this recreation to cellular (you already know in addition to networking, efficiency, or system points) I believe it’s the one downside that had probably the most care put into it, has a number of invisible work that went into it from all sides, and is arguably one of many issues that may have probably the most affect on gamers since controls that really feel bizarre or damaged would positively not be perfect for such a enjoyable recreation coming to a brand new platform.
