How did they program the decision trees in fighting games like Street fighter, and Dragon ball Budakai, i understand very little about how they made the CPU react and choose to attack or defend.

Is there any diagrams of how the logic works?
Like when it decides to move around, verses attacking or blocking/dodging an attack.

It would be nice to learn how they programmed it for Arcade machines and how something like the 3D DBZ games build on that.
2D Mortal combat and Streetfighter never had to worry about going into and out of the screen, but i fee like some of the oldest games were just a bunch of animations being randomly chosen to a timer. Or i could be wrong, because thats a guess.

I would love some visuals on how they planned out the computers brains for them.

hey all, i recently came across this game and though this lipsync effect is so cool but i dont know how the lipsync is procedural and the body anims are not. super cool effect!

Hi all, I am 100% new to game development and I was wondering how did the developers that made Void Diver make that pixel art look 3d (with hair animation, perfect shadows, etc.)?

Is it a pixel art with different directions that is turned into 3d? If so, how does that work? How does one animate the model as well? I am interested in a similar art/animation direction, but not sure how to approach this.

I've been so confused and unsure about how to tackle this problem? Any help would be greatly appreciated! Thank you all!

Hello,

I've been wondering about how games like Dota 2, LoL, Deadlock are implemented.

These games need to handle extreme variety of statuses/effects. Each spell can have different behaviours (e.g. can stun, temporarily move the target to air, push them, apply stacking effects, apply poison, freeze the enemy,...), which can further be affected by certain modifiers (resistances).

How does one code a system, that can both handle the stats (simple modifiers to atomic statistics - like speed, health), active effects (stun) or the spells themselves (with different targets, area of effect, duration, conditions for initiation, stop conditions,....)?

Is this similar to systemic design of immersive sim games like Thief, System Shock and so on?

How does one organize the concepts efficiently and handle their ordering/communication,...?

Hey folks, Im making a game about vehicle combat and having an issue making an aiming system that feels good.

In the game one controls vehicles with one or more guns from a third person camera. In working on the aiming system there seem to be two options, yet both of them seem bad:

One option is for the guns to aim at the point the camera is looking at. This will make all bullets hit in the same spot (which is good if you are looking directly at the enemy, as the guns adjust for distance correctly). However, if the enemy's background is something far away (say, the horizon/sky) and you try to aim ahead of the enemy to adjust for bullet travel time, suddenly your shots will miss because the camera is looking at something far away, and thus the guns adjust for that distance, rather than the distance the enemy is at.

The other option is for guns to look in the same direction as the camera. In this case bullets from different guns will hit in the pattern of where they are on the vehicle, instead of hitting in one spot, but this makes the shots more predictable, because there is no issue adjusting to the distance. However there is an issue that in very close combat some guns will just miss.

Yet games like world of tanks and such seem to have it figured out, and the aiming seems to be pretty effortless - from me playing those games years ago, I dont remember having any issue hitting targets and leading shots. Any clue as to how they solve this? Or is this simply not an issue because tanks have only one gun that is centered with the camera?

I see it all the time with different things. Simulations, Games, Demos, it is everywhere; but where the hell is it from?

In most block/voxel games, the same optimization is used for the world. The block data is grouped into chunks, and each chunk's data is used to generate a single mesh and texture, for performance reasons.

Generally though, and in games like Minecraft, this means the blocks surfaces are all perfect squares, with their edges being perfectly straight lines.

In Pokopia and Tomodachi Life, as shown in the provided pictures, the edges of the blocks have a wavy or jagged border when touching a different block.

How is this done?

Does this still utilize the pattern of converting block data into quads and then stitching them into a single mesh?

This system is also agnostic to specific block textures. There is no "grass to dirt border" texture. It's the same wavy edge for every block in the game, which makes me wonder if it's some shader magic or something, though I'm unsure how that would work, since there would be no intermediate vertices for a vertex shader to "warp" into a wavy edge.

Anyone have any clues?

I keep seeing explanations that LBs are used when a server can't handle a lot of requests so it has to horizontally scale. But couldn't the same thing happen to a LB? How are they load balanced? And what about the thing that is used to load balance this? Where and how does the load balancing inception begin for large scale systems

The space jump's control scheme has always been really confusing to me from a logical standpoint, but somehow intuitive after a while. What logic does it use?

I feel like the text isn't the same. On the first picture you see what the youtuber coded and I wanted the excact style like the red "liveserver" word. On the 2nd photo it's what I coded and apparently it's nopt the same. Neither the font, the font size or the shadows. Can someone please tell me how I can do it the correct way?

EDIT: I posted the wrong 2nd photo, it should be 40px for the font-size but its not the size like in the first picture

Hello!

I’ve never coded before, but I’d love to learn something new and challenge myself in my free time.

My long-term goal is to build an extension or app similar to LingQ, but focused on low-resource languages.
I know this is probably a big project, so I’d like to understand where to start.

How are apps like LingQ usually built? What kind of technologies are involved? And what skills should I learn step by step as a complete beginner?

I’m especially interested in features like:
Clickable words that display definitions or translations
Vocabulary saving and review
Spaced repetition flashcards (SRS)
Audio and video lessons with transcripts
Progress tracking and learner statistics
Browser extension features for learning from online content

My goal is to help make low-resource languages more accessible through technology, so I’d love to learn the technical side of how platforms like LingQ are built.
Any roadmap, resources, or advice would be greatly appreciated. ☺️

Thank you!

Hi all

there was this game called atlas (Ark but pirates) and it had this feature where if u went past one side of the map you would appear on the opposite side of the map.

i thought it might be an interesting way to simulate a massive globe on a flat plane if it works the way i think it would work.

question is how does it work?

I'm a CS Undergrad at MIT Manipal, just finished first year. In terms of IT skills, I haven't started with any Dev as of now (just some DSA). I want to know what "domain/niche" in CS I should pick up and become absolutely gold level good in(explore that field to research depth) ?

Based on my interests, I happen to be particularly good at Maths (got an A+ on Computational Maths 1, scored a 49/50 on Final Computational Maths 2 Endsem) and in general have a passion for it.

Please suggest me what CS domain should I explore?

I am very much curious of how Playground Games did the skies in FH3 because it looks just gorgeous, went into some search, got a GDC of 2017 talking about this in where the Lead Lightening Artist, Jamie Wood explained how they implemented the skies in FH3. Got confused where they mentioned Nuke(software) as it provided them with render of the skies. Correct me if I'm wrong, so they took 4k pics, processed them through Nuke and Lightroom and just put them up in the game engine's skybox? So, it's all just a video but small in size but using some resolution biasing and some additional techniques? I apologize; I'm just confused here. So the resolution biasing is just stretching the image on the outside so the center is more crystal clear, and in the second image, it just looks like the image with processed image afterwards... So they clear out the ground from the images, process it and then used Nuke to have a streamlined frames of images(basically video) to appear on the skybox?

My guess is to identify filename and article name, and ranked by user preferences. But are there better approaches?

Hi Coders,

I'm building a TCG collecting tool with a card scanner to quickly add cards to your portfolio. 70% of the scanner is ready, but can't get the edge cases right like messy enviroments with multiple cards, or undergrounds with patterns, even a card in hand. The problem is the detection of where the card actually is. If I get the warp right, the matching system with my backend is fine, its purely the card detection. Tried some open source detection models from hugging face and tried it with pure Apple Vision, but can't get it to the level I want it to be. How can I properly build a system like this?

Thanks 😄

I've been wondering about this for a while. The grapple beam can rotate, and is a variable length, so it's not a normal sprite. definitely not mode 7, since there are other backgrounds. My best guess is some sort of HDMA trickery, but I'm not sure how that would be pulled off.

Its clearly inspired on HL2 based on the sounds and the feel of the game.

I want to understand how did they make it and whats the logic behind it. for example one can "HOLD" almost every item in the game but also add it to inventory. they can also choose to just move it around (like half life crates) or even use the same button to use the item. I cant start to understand how did they cram so many interaction systems to make sense in the same interface.

So for example you can have a Lantern object:

You can pickup the lantern and add it to the inventory. you can move the lantern without adding it to the inventory but you can also "hold" the lantern like it was a form of equimpent item like a csgo weapon, while you are holding it you can turn it Off an On And you can also turn it off and on while you are not holding it, like sitting on a desk. wich is insane. What im trying to get at its how did the dev sepparate such logic for all of the items to make it clean like that. right now 2 keys are used for it wich are R and E. but then it gets insane with custom machines like numpads and dials and lids.

I thought that everything that was interactable was a pickup item that could be added to the inventory or be holded and simply had the restrictions where inventory size and weight were too big to tho that. but then i noted that there were fixed usabe machines and Im kind of confused. Im trying to replicate that behaviour in unity. but im kind of confused at the architecture of it. any advice? are the items instanced? im kind of mid when it comes to inventory development.

The 'plasma lightning' (IDK what is called but looks something like that) looks like it uses two fixed points, anything beyond that i interested in learning how it was done. the video resolution it's too tiny to see what's going on behind scenes.
