There’s a scene within the new moon touchdown film, First Man, wherein Ryan Gosling’s Neil Armstrong climbs right into a g-force simulator to courageous the consequences. The steel bars round him spin each which approach, like playground gear in a hurricane, and he falls unconscious inside seconds.
The comparability is perhaps hyperbolous, however it’s nonetheless what we’re reminded of when lead technical designer Harry Ketteringham describes the ordeal of designing a digital camera to swimsuit CrossVector X – an on-rails area game that sees you skimming the floor of alien planets in a fighter ship.
“It’s quite tricky,” he tells us, “because the ship is following the spline, you’ve got the camera following behind that spline, and then you’ve got the player aiming, the ship rotating, and the spline camera rotating around. You have all these angles and rotations trying to work together and it feels quite nice at the moment, but it’s not perfect.”
It’s clearly not not working, since we end the gratifying EGX construct of the game with out pulling a Gosling. But there’s loads of problem concerned in constructing one thing like CrossVector X, the place management is a continuing negotiation between the game and its participant.

Level design for an on-rails shooter is a curious course of with out apparent parallel in different genres. The staff at OatCake Games must construct a satisfying planetary floor atmosphere so that you can zip by means of, in fact. But that world additionally must gel with the set path the ship follows by means of it – the spline Ketteringham refers to. It’s no good making a planet pockmarked with areas of curiosity if the spline doesn’t take you thru the perfect bits at a tempo that means that you can recognize it.
“It was quite a challenge for us,” Ketteringham says. “It’s definitely a new undertaking because we’re quite used to designing single-player levels you can block out. We had to sit down with pens and paper and figure out how is our ship going to move around the world, how our camera is going to follow, and of course there are still some issues to work out, bearing in mind it’s pre-alpha – it’s trial and error.”
Ships preventing within the background give a way of bigger battle
Once the pre-alpha stage was designed on paper, the staff constructed terrain in a artistic landscaping device known as World Builder, returning to it till the atmosphere felt proper. After that, the tweaking course of started to resemble the course of a CG movie.
“If something isn’t quite right we can adjust the spline track ever so slightly and the camera will follow it,” Ketteringham explains. “So if you want a nice shot of the ship going upwards you can tilt the spline. We can manipulate it quite a lot so we can get nice panning shots.”
Ships dogfighting within the background give the sense of a bigger battle you’re merely meandering by means of, and the staff intends so as to add extra of this ambient cinema – hinting on the story and factions it has within the pipeline.

The sharp, frozen edges of CrossVector X’s planetary floor are highlighted by daring traces that Ketteringham describes as “Borderlands-y.”
“Our lead artist went ahead with this cartoony style,” he continues. “We made everything really bright and colourful to stand out, and then we started messing around with it so see what looked nice, and we thought black outlines really make the terrain stand out to us.”
What may not be apparent as a participant is that these outlines aren’t baked into the atmosphere beforehand, however willed into existence throughout play. “It’s rendering from the camera’s perspective,” Ketteringham says. “So it detects what side is closest, finds the edges, and puts in the black line depending on where the camera is angled.”
Despite methods like these, it’s the digital camera and aiming that has remained probably the most constant and formidable problem throughout CrossVector X’s improvement. Thankfully, altering it has been straightforward, Ketteringham working for probably the most half in Unreal Engine 4’s Blueprint scripting system to bypass coding.
“We use object oriented programming so we can go in and change things and shouldn’t get any backlashes with things coming in previously,” he says. “You probably can tell the aiming is not quite perfect and I think I’ve figured out why. I’m going to change that tonight.”
CrossVector X is coming to the PC. Unreal Engine Four improvement is now free.
In this sponsored sequence, we’re taking a look at how game builders are profiting from Unreal Engine Four to create a brand new era of PC games. With due to Epic Games and OatCake Games.
