This is The Gunsmiths, a SE7EN.WS sequence about videogames’ favorite interplay: capturing individuals instantly within the face. There is not any scarcity of nice video games the place gunplay is the primary draw, so we needed to dig down into these video games’ inside workings, breaking them aside at a device bench and seeing the elements unfold out throughout its floor. For our fourth characteristic within the sequence, it’s the balletic bullet dance of Max Payne 2.
The previous is a puzzle, like a damaged mirror. As you piece it collectively, you chop your self, your picture retains shifting. Still, I keep in mind it like yesterday – my first sufferer in Max Payne 2: a balaclava-clad goon close to a doorway, his again to a shelf stuffed with medical gear. I hearth a shot – straight to the top, dropping him quicker than a grenade with a pulled pin – and he hurtles backwards as time slows to a crawl, knocking the cabinets onto the ground, spilling the gear all over the place, and inflicting one other unit to crash into his limp corpse.
All of this was unscripted. It was the primary time I had seen real-time physics, and it made that single, easy encounter endlessly replayable. The thuds and crashes as physique elements interacted with their environment, kicking up mud with each collision gave your complete scene weight. All of those interacting items made each encounter really feel unpredictable. Of course, this additionally added to the workload for the builders. The audio designer needed to create collision sounds for each kind of fabric a dynamic prop may have, simply in case any flailing physique elements determined to donk into them.
Peter Hajba labored on Max Payne 2’s spectacular audio – together with foley work for a few of the ambient noises to again its noir-style comedian strips – however he additionally has a hand in creating the look of the sport’s bullet impacts and particle results. “For as long as I remembered, I had been kind of obsessed with bullet impact visual effects, not just in films but also in games,” Hajba tells me. “It felt like they could be done better. So for both Max Payne and Max Payne 2 I basically just wanted to do the most awesome bullet impacts ever made for a game. Impressive puffs of dust and sparks, pieces of tiles, bits of paper and the like.”
“Max Payne’s shoot-dodge dive was an interesting idea that our graphic artist Teemu Heinilehto originally came up with,” Hajba remembers. “He just wrote this enthusiastic ‘what if you could do this?’ email and we rolled with it. Our programmers needed to figure out a way to blend together eight diagonal dives, and for that I had to animate eight directional versions of the dive we could blend in between. So you could dive in any direction, then point the guns in another. It allowed aiming the guns horizontally quite seamlessly – but upwards and downwards aiming would have required additional layers of blending. We couldn’t just rotate the arms as that would have misplaced the grip and looked odd, so we had to drop it. Comical moments of diving down a staircase and pointing the guns forward but shooting straight down ensued.”
Before this, Max Payne may solely dive in a single path and aiming was locked to a restricted cone straight forward. The choice so as to add this twisty animation mixing made the gunplay really feel far more fluid. An analogous factor occurred with Max Payne’s Bullet Time mechanic. Originally, time slowed at set factors within the ranges and was not player-controlled. 3D Realms got here up with the idea of constructing it player-triggered and turning it right into a useful resource that Max wanted to earn. Without these improvements, Max Payne and its sequels would have been rote third-person shooters, if sequels ever even occurred in any respect.
To actually get throughout that Matrix-esque bullet dodging fantasy – full with slow-mo shell ejections and sliding mechanical elements – the sport’s bullets needed to exist bodily. A number of video games use hitscan strategies that immediately harm their targets with each correct shot, however Max Payne’s bullets really journey by way of the world. They are barely seen throughout regular velocity gameplay, however grow to be clearly seen throughout Bullet Time. “This took an extra effort to get working correctly, especially at high speeds – where you need to interpolate the hit detection so the projectile doesn’t miss a target between frames – but in the end it paid off well,” Hajba explains.
Max Payne’s engine allowed Remedy to make the bullets journey at practical, supersonic speeds, ought to they need. But this is able to have meant they might be laborious to see, travelling as quick as they have been, even throughout Bullet Time. So they did the wise factor and slowed them down, making certain Bullet Time lived as much as its title.
“The particle effects were also calculated accurately and frame rate independently,” Hajba says. “Theoretically, if a projectile traveled at 10,000 m/s and the particle effect attached to it emitted particles at 10,000 per second, you would get a ten kilometer row of 10,000 particles one metre apart, as opposed to common cases where emissions are buffered per frame and you would get clusters of particles emitted at each frame – known as ‘popcorning’ of smoke trails. This caused extra CPU load – the Max Payne particle engine was more expensive than other systems at the time – but it was truly worth it during slow motion.”
Max Payne 2 made this course of extra sophisticated nonetheless, introducing stretched or elongated particles, moderately than the extra easy sq. billboards of the primary sport. Snowflakes and bullets sparks within the unique needed to be rendered right into a baked sequence of frames, on account of texture reminiscence limitations, which gave them a pixelated look.
“For Max Payne 2 we made a rather clever particle stretch system which allowed screen space stretched billboards: a billboard would stay aligned towards the screen, but it would be skewed according to the direction it was traveling in screen space,” Hajba recollects. “This allowed very nice looking bursts of not just elongated sparks, but also smoke and dust being stretched a bit to give a sense of motion and connecting even a smaller number of particles nicely. We watched some action movies that had plenty of bullet squibs frame by frame, and noticed how the dust clouds looked ‘stretched’ due to motion blur.”
Layered excessive of those results have been the decals, bullet holes, and the like littering the atmosphere, making you’re feeling such as you had induced chaos within the aftermath, maybe when backtracking. The programmer, Olli Tervo, ensured each room had its personal decal buffer, and that these really received saved within the sport save state – so should you got here again to your sport session later, all of the bullet holes and blood stains within the stage have been nonetheless in place. To decrease GPU stress, all of those decals have been merged right into a single mesh per room. This compromise did imply that there was a restrict on how a lot chaos you might create, however the cap was excessive – you needed to actually attempt to attain the restrict.
Of course, none of those visible thrives would matter if the audio didn’t make the act of capturing sound satisfying. Unfortunately, they couldn’t precisely mirror the weapons’ real-life counterparts, because the price of fireplace for every gun had been slowed right down to work with Bullet Time. “The dual Mac-10 submachine guns were an extreme case,” Hajba says. “The excessive firing charges and twin weapons meant that spraying projectiles at a sensible price would have induced simply means an excessive amount of CPU load. So a little bit of smoke and mirrors have been utilized. The firing sound was a queue of bursts of 4 (or eight for twin) pictures, to drop the projectile price to an inexpensive stage.
“I went roughly by really feel and ear, however with some ideas: gunshots should not be fatiguing or annoying to hearken to; there wanted to be variation on repetitions; they wanted to sound highly effective; and the participant’s weapons ought to all the time sound extra highly effective than the enemies’ weapons. It was all very a lot studying whereas making, however a superb few classes had already been discovered through the improvement of Max Payne. The iconic Bullet Time begin sound was a little bit of a fortunate accident. I combined collectively a number of impacts and explosions that I pitch bend down with Sound Forge. Done.”
So, the following time you diving down some stairs in slow-motion, filling some goons stuffed with lead as your cartridges gracefully eject from you twin pistols, spare a thought for all of the elements that match collectively to make it work. Show some appreciation for the gunsmiths at Remedy.
