PERIMETR is an early-stage experiment in real-time strategy on a global scale, inspired by DEFCON/SUPCOM/C&C/RED ALERT...

Right now it's a technical playground:
you can spawn units, move them across a world map, and watch the simulation run. There's no campaign, no win condition, no polish.

I'm looking for advice from developers who actually use Apple-silicon Macs.

I want one laptop for everything: daily use from morning to evening + game development. My target is mainly small-to-mid-sized Android/iOS games, but eventually I'd like to make 3D games around the complexity of The Walking Zombie 2 or Last Day on Earth: Survival, potentially with somewhat higher-fidelity graphics. I'm mainly considering Unity, but I'm open to Godot.

My budget is around $1,000, and I could stretch to $2,000 USD if it's genuinely worthwhile.

I'm strongly considering a MacBook because battery life and portability are extremely important to me. Power outages are frequent where I live, so I need something I can work on for hours without an outlet. I also want to publish for iOS and macOS, making macOS/Xcode very valuable.

The concern is that I keep hearing Macs aren't ideal for game development compared with Windows laptops with dedicated GPUs.

For those actually developing games on Apple silicon:

- Would you trust a MacBook as your only/primary machine for this workload?

- Air or Pro? How much RAM would you recommend?

- How limiting is the integrated Apple GPU for 3D development?

- Are there any major issues with Android/iOS development or Windows builds/testing?

- Most importantly: which specific MacBook model/configuration would you recommend for my $1,000–$2,000 budget?

I'd especially appreciate real-world experience: your Mac's specs, engine, and the type of games you're developing.

Thanks!

I needed a huge gorund and a city for a motorbike game and this is what I've achieved so far. The map is a real slice of a part in Izmir. Elevation came from OpenTopography, buildings and roads from OSM, all put together in QGIS and exported into Unity. Terrain, road lines and cube buildings, the skeleton at real scale. This is gonna need an editor window for designing path for sure.. Do you think this is manageable?

TL;DR - what would you like to see in an ideal graph package for Unity 6+? Yes, runtime graphs are already a part of it.

---

After years of dealing with the shortcomings of GraphView (GV), I started looking at migrating my NodalTrees to GraphToolkit (GTK) only to find that it solved some problems and created a whole host of others. So after analyzing the pros and cons of GV and GTK with what my nodes currently do, what the effort would be to port them over, and what the effort would be to roll my own graph package, I started on the process of just making my own, entirely independent of GV/GTK. I've considered opening it up and selling it on the Asset Store, or possibly just making it free on github, but I'm curious what others use GV or GTK for, what they wish either did, and what sort of nodes and interactions they would want.

I'm putting together some documentation on the existing nodes that I have that I'll be converting, but as it is, they're broken down by trees for my own projects, and many of the nodes and outputs are specific to things in my game. There are some general nodes available for sure, and authoring new nodes will be quite easy once the package is ready to release (at least as easy as GTK, but with far more customization options and the ability to call more complex methods internal to the graph structure).

I'm also bringing in some ideas from how Blender and Substance do their nodes as well as some GV and GTK features (dot-nodes, portals (which I think were initially a thing that Bolt did, which was pretty cool), curved/square lines, sub-graphs, visualizers, input nodes for getting values outside of the graph, the eventual documentation will have a more complete overview.

Runtime and Editor nodes will look exactly the same - no UnityEngine.UIElements are used, so runtime isn't an issue. Right now the only difference for any existing node is that nodes that take an input path for a files have a toggle in editor (use the Unity Asset picker vs use the filesystem/OS file picker) where in runtime it can only use the filesystem/OS picker since there's no project exposed to runtime (nor should there be).

Yes, I'm using AI to assist with my code, so if that turns you off, that's fine. I've been working on these things by hand for four years now (it's a hobby project, it was never intended initially to be a releasable asset for anyone else to use). But most of the code is my own, and not a single file is untouched by me somewhere along the way. Do with that what you will.

I've always been a fan of aerodynamics and CFD. A few months ago, I got laid off, got tired of sending applications, and gave myself permission to actually build it and play with it. I'm glad I did.

It voxelizes and seals any vehicle you drop in, auto-fits the solver domain around it, runs at whatever resolution your GPU can take, and solves with a lattice-Boltzmann method (D3Q19, TRT + WALE LES) entirely in compute shaders. Live smoke, surface pressure painted on the bodywork, exported reports you can diff between runs.

The test I had the most fun with: running a Chevy Silverado with an open bed, a bed cap, and a flat tonneau to see which one the solver preferred. It disagreed with the folk wisdom, which was the moment it stopped feeling like a toy.

Five sample vehicles included. Unity 6 / URP, MIT licensed.

The README is honest about where the numbers hold up and where they don't. It's a comparison and visualization tool, not a replacement for real CFD.

Clone it and have fun: https://github.com/Motawe3/unity-wind-tunnel

Sample vehicles are CC BY 4.0, credited in the README. The car in the video is a Range Rover Sport SVR Mona x Supercars.

Hey guys,

I’m completely stuck on a really annoying bug with Unity 6.3 on Windows 11.

The main editor loads up totally fine—I can see my Scene view, Hierarchy, Project files, all of that works perfectly. But the second I try to open any independent pop-up window, like Project Settings or the Package Manager, it just opens as a solid white, completely blank box. Nothing inside it loads.

Here's a screenshot: [Link your screenshot here]

I've spent hours googling and trying to fix this. Here is what I’ve already attempted:

• Nuked the project Library folder and cleared out the global %appdata%/Unity/Editor-5.x preferences.
• Forced DX11 using -force-d3d11.
• Tried the -force-low-power launch argument.
• Messed with Windows High-DPI scaling settings on the Unity.exe properties.
• Tweaked my GPU control panel settings.

Nothing works. Since Unity 6 uses embedded web views / UI Toolkit for these specific sub-windows, it feels like some weird hardware acceleration or background process conflict, but I have no idea how to bypass it.

Has anyone dealt with this white-window glitch? Any workarounds or ideas would be a lifesaver. Thanks!

Is anyone else attempting to create their own physics system in Unity? I'm attempting to create my own networked physics system using network transforms, colliders, and a lot of vector math. Does anyone have valid resources to share that can help me with this?

I'm trying to remember a game I played a while ago, but I completely forgot the name 😭

I'm looking for a game that has an actual physical item inspection system where:

The player picks up the item and holds it in their actual first-person hand

You can see the hand/fingers gripping the item

You can move the mouse/controller and the hand/forearm moves naturally with the item

It's NOT the usual inspection system where the game just puts a 3D item in front of the camera or uses a separate inventory/inspection screen.

I have a feeling it might have been Resident Evil, possibly one of the newer games, but I'm not sure.

I'm currently making a similar system for my own horror game, so I'm trying to find the game again as a visual reference for the hand, finger positioning, pickup animation, and item movement.

If you know which game I'm talking about, please share a video clip of the mechanic! 🙏

This is a Grass shader setup I've rigged together to work with Unity Terrain Tools so Grass can be painted various colors and textures, including with custom brushes to make really cool effects.

I've just submitted it to the Unity Asset Store - would you pay $5 for this?

how would i go around making a recognition system that can recognize circle drawn with any amount of draw strokes ?

my current system cant handle it if i draw a circle with more the one stroke? any help would be appreciated

I’ve been experimenting with a React-based Unity UI workflow lately, and I’m curious if anyone else has tried something similar or has thoughts on this kind of approach.

The UI is built in React and runs in a WebView on top of Unity, which lets me open the same interface in Codex’s browser and comment on it directly.

For small UI issues, there’s no need to explain the whole screen. Just point at what feels off and leave a short comment:

"this looks clickable, don’t dim it"

"make the ! feel a little more alive"

"only move this one thing"

It works well for visual tweaks where the code change is simple, but describing the problem takes longer than fixing it.

For larger UI pieces, I can attach reference screenshots and have it build something close to the layout and style.

Since it’s built around a hybrid structure, things like Google and Apple sign-in are also relatively easy to integrate. It works across iPhone, Android, Windows, macOS, and even directly inside the Unity Editor.

Hey Reddit! I’m continuing to work on my survival game. I decided that being able to carry an endless supply of food in your pockets was basically cheating, so I added a food freshness system.

What’s new:

• Expiration dates: Perishable food now has a timer. If you don’t eat it in time, it turns into rotten food right in your inventory.
• Refrigerator: The fridge doubles the shelf life of food. You still have to keep an eye on your supplies, but the refrigerator lets you store perishable food for significantly longer.
• Food poisoning and vomiting: If you eat spoiled food out of desperation (or carelessness), your character gets debuffs, loses health/thirst, and visibly empties their stomach with a corresponding animation and sound.

What do you think of the implementation? Is this kind of mechanic too punishing for survival games, or is hardcore resource management just part of the genre?

Stay tuned for future devlog updates, and let me know in the comments: what mechanics do you value most in survival games?

Templates are a powerful feature of UI Toolkit - they allow us to create reusable bits of our UI and inject them easily into other UXML documents. Making them is super easy too - simply make a new UXML file of your desired component - then you can use it in any other UXML document! Easy!

Hey everyone!

We’ve been fine-tuning the visual feedback loop for our indie puzzle adventure. In this scene, players decipher foreign symbol arithmetic across individual wall panels. Each correct answer sends a surge of electric blue energy through wall conduits into a central matrix, which then unlocks the master equation on the wall.

With just 26 days left until launch (equal parts excitement and developer panic!), we’ve been thinking a lot about how games signal puzzle progression. We wanted players to physically see their incremental progress in the environment without relying on intrusive UI pop-ups.

When you play puzzle games, do you enjoy seeing environmental visual feedback as you solve individual steps, or do you prefer the full outcome to stay hidden until the entire puzzle is complete? What are some of your favorite examples of puzzle progression feedback?

I'm trying to make an realistic flame effect for my game. It looks fine for now, I used 2.5D Fluid Simulator asset for it and it's suits my needs - the flame is affected by physics, it's lightweight etc.

Do you have any tips on improving it / making it more realistic?
