Shaders weren't a thing back then (because graphics cards weren't a thing). I played Doom on a 386 (under 40 MHz) for example. That CPU had to do EVERYTHING -- not just collision, player input, and enemy AI but rendering. They simply couldn't do complicated algorithms to mimic shaders outside of table lookups. It is impressive that they accomplished what they did.

Important to note for GZDoom types: You may notice enemies do NOT spot you by default. However, in vanilla, enemies will still spot you through the power-up. Heretic's Shadowsphere DOES have the GZDoom style mechanic in its vanilla game though!

@DoomedMechWarrior Ай бұрын

Funnily enough, one of the recent GZDoom versions (4.12, but seems to be fixed now) somehow broke angle randomization completely. So you would have enemies attacking you as if you didn't have it.

@phantombeta Ай бұрын

Also important to note pretty much the whole ZDoom family of ports has this, including ports like Zandronum. The change in behaviour came when ZDoom got Heretic support, because the code for that behaviour from the Shadowsphere was intentionally added to Doom's Blursphere. The early days of advanced Doom ports was a wild west of changing the game's behaviour, keeping the vanilla game as is in more advanced ports largely started with PrBoom and its descendants, with their features like complevels.

@Shepardus Ай бұрын

If you play around with it in GZDoom you'll notice that sometimes the enemies notice you anyway. They have a random chance of spotting you if you get too close or move too fast, so keep your distance and move slowly (slower than walking speed) and you'll remain hidden for as long as the powerup lasts. This is also taken from Heretic's Shadowsphere.

The irony is, in most shooters a blursphere or similar item would be unambiguously good, because you had no chance of dodging all the bullets anyway. You're basically hoping the enemy misses you, so a higher chance of that is never bad. In classic doom (especially nowadays) that's only true for hitscan, or in rare cases where there's just a comical amount of enemies shooting you. It's an item that makes sense in every fps except the one it's in.

There was also a flag to make any entity subtractive and double their HP, that's how they made the Nightmare Specter, but you can apply that flag to any enemy. There were Nightmare Imps during development but were discarded, there's a magazine scan with a screenshot of one in E2M6, but you can easily make any Imp a Nightmare Imp by enabling the flag on one of them.

On the Super Nintendo version of Doom, the partial invisibility power actually makes you invisible to monsters. You can walk right in front of them and as long as you’re not inches away they won’t see you. On the SNES the Partial Invisibility sphere is one of the best power-ups in the game. The SNES version had to cut some serious corners but this is one instance they actually improved on the original game.

@BPCRevere Ай бұрын

Yeah, the SNES version was the first one I owned, then playing other formats made me wonder what was broken about the invisibility. The SNES version did have a couple of interesting aspects with the weapons - I believe the shotgun was just a single shot with a heavy damage multiplier over bullets, making it more like a long rifle, and the BFG worked differently, with a big splash like a souped up rocket launcher. Plus there was a fun bug where the backpack gave you ammo for weapons you didn't have yet and you could trick the game into giving you a single shot with "ghost" weapons by switching and pausing weapons.

@NerfPlayeR135 Ай бұрын

The partial invisibility probably works that way on the SNES to compensate for monsters' lack of sprites that aren't front-facing. Which means it's outright impossible to ambush them.

The thing is that it messes with muscle memory of seasoned players who already know the patterns and dodge instinctively, often preemptively.

The blursphere is one of those nuanced powerups that mappers don't seem to know how to use to its fullest extent. There are more uses than anti-hitscan protection or extra challenge in a projectile-based arena. For example, a combat puzzle where your movement is restricted so dodging projectiles is harder could benefit much from a blursphere secret before it - not as broken as an invuln but still a big help, similar to the radsuit secret in Stardate 20x6's Vehelits, that makes the last ambush a lot more manageable. Oh, there's also yet another name for this powerup: Quantum Stone. Credit to Zeppelin Armada for this one.

This only applies to the original 320x200 resolution. 2) Heretic's translucency effect incorrectly cuts itself off at the top/bottom of the screen despite not needing to because those lines were erroneously left in as a leftover from the fuzz effect.

I wondered about some stuff about partial invisibility. Like why Demons face different directions from where they shoot. But this also does make me wonder something else. If you were to set the angle offsets of the demons face target angle to be the ones used for projectiles, instead of another random angle offset for the projectiles, if that'd have made the Partial Invisibility much more useful against projectile based monsters, as it would mean you get a slightly clearer idea of where the demons about to shoot. And it doesn't fuck with muscle memory as much. I personally like that idea more then just making partial invisibility prevent demons from seeing you until you do something to alert them.

The first time I played No Rest For the Living, I had issues with the chaingunners in Map 4 being rather effective snipers. That is until I found the secret partial invisibility, and suddenly they weren't such a challenge at all. I can only imagine the evil laughs that were had when placing them everywhere in Dead Simple, though.

Command & Conquer has a similar but more elaborate effect on its Stealth Tanks, but, notably, they did _not_ include proper range checking, meaning it will read outside its buffer on the bottom of the screen. But given the lax memory management in DOS, this rarely gave any real issues in the game; it just showed some messy glitchy pixels and that was all. That is, until the Win95 port got re-released on Windows XP, and suddenly _everyone_ was getting these crashes, and community hackers had to figure out how to fix it in the game's bytes.

Back in the 1992-1993 when the game was developed, no one played still maturing FPS games by zooming through the maps, strafe running in circles around enemies and spamming rockets all in the same time. Most players used arrows and keyboard only for playing, turning in place and standing during shooting. Then Partial Invisibility had much more sense, as it was crafted for mostly static or not much mobile targets.

Great video as always! One aspect that wasn't covered was how (if I'm not mistaken) invisibility is interpreted by sleeping enemies differently in different source ports? I remember playing certain maps/ports where monsters don't notice you until you shoot them or bump into them, even when standing right in front of them?

@decino Ай бұрын

I've briefly mentioned that in the powerups video but usually I leave out source port specific behaviour in these deep dives.

@@decino Makes sense. A weird deviation in "core logic" for a port to make. I remember feeling like it was more of a bug than a feature when I discovered it the first time.

@phantombeta Ай бұрын

It's a quirk of ZDoom family of ports. It's actually because partial invisibility in ZDoom uses code from Heretic's invisibility powerup. ZDoom got support for Heretic fairly early on, and back then making changes in behaviour like this were commonplace in advanced ports, even the Boom family used to make changes like that before PrBoom and its descendants. GZDoom has been working to undo many of these changes for a while now with compatibility options for these gameplay changes
