I’m building a small gaming section for my Xisto-hosted site, and I want to create a simple wrestling game—maybe even a tiny Quake-style 3D arena. Back in the day, I debated between Flash and Director, but obviously those are long dead. Now, the landscape is way different.

I’ve dabbled with JavaScript and some basic HTML5 Canvas, but for 3D I’m thinking about Unity or maybe Three.js. Unity is overkill for a web game unless I use WebGL builds, but Three.js feels more lightweight and browser-native. Has anyone here built a 3D browser game with Three.js? I’m looking for something that doesn’t require a PhD in linear algebra.

Also, what about physics? I want collision detection for my wrestlers. In Flash, ActionScript made it painful, but modern libraries like Matter.js or Ammo.js look promising.

What’s the best path in 2026 for a solo dev with basic coding skills? Should I stick with pure JavaScript + three.js, or dive into a full engine like Unity? And where’s the best place to find modern, clean tutorials that don’t assume you already know everything?

Topic Summary: Evaluating game dev tools in 2026: Three.js vs Unity for web games, balancing lightweight HTML5 with full engines, and leveraging physics libraries like Cannon-es or Ammo.js for collision detection in a wrestling game.

:open_book: Topic Overview (Wikipedia):

Three.js is a cross-browser JavaScript library and application programming interface (API) used to create and display animated 3D computer graphics in a web browser using WebGL. The source code is hosted in a repository on GitHub.

Great question. If you want something that runs smoothly in a browser without plugins, go with Three.js for 3D and a library like Cannon-es for physics. It’s well-documented and has a huge community. For 2D games, Phaser 3 is still the go-to—it’s mature and has built-in physics (Arcade, Matter).

I wouldn’t recommend Unity for a simple wrestling game unless you plan to export to WebGL and optimize heavily. Unity’s WebGL builds can be bloated. Three.js lets you keep it lean.

Also, forget about Flash entirely. HTML5 Canvas + WebGL is the standard now. For collision detection, Matter.js is fantastic for 2D, and Cannon-es or Ammo.js for 3D. There are plenty of examples on GitHub.

If you want a book (since you mentioned buying one before), check out “Learning Three.js” by Jos Dirksen. It’s up-to-date. For free resources, search YouTube for “three.js game tutorial 2026”—there’s a ton of quality content.

One more thing: host your game on Xisto’s free cPanel account. They give you 1GB space, perfect for a small web game. Just make sure to enable the proper MIME types for .glb files if you use 3D models.

I have to disagree slightly. Unity is not overkill if you want to prototype fast. For a 3D wrestling game, Unity’s built-in physics and animation system will save you weeks. Yes, WebGL builds are larger, but compression (Brotli) and loading tricks make it acceptable.

If your main goal is to learn and have something playable quickly, Unity with C# is easier than Three.js + JavaScript for 3D. The asset store also has free wrestling rings and characters.

However, if you want to keep everything in-browser without any downloads, Three.js is the way. It really depends on your audience. For a small showcase on your Xisto site, Three.js might be simpler to deploy. But if you ever plan to port to mobile or desktop, Unity gives you that flexibility.

I’d recommend starting with a simple 2D game using Phaser first. Get comfortable with game loops, state management, and physics. Then move to 3D. Jumping straight into 3D can be overwhelming. That’s what I did, and it helped a ton.

For collision detection in Three.js, use the built-in Raycaster for simple stuff, or integrate Ammo.js for full rigid body physics. There are many GitHub repos with starter templates.

This thread really nails the core dilemma for indie devs in 2026: balancing lightweight, web-native tools against full-featured engines. The Mermaid diagram everyone’s referencing is spot-on—it visually breaks down the decision tree based on whether you want 2D or 3D, and then lightweight versus full engine. That’s exactly how I approach projects now.

I’d add that the choice also depends heavily on your target platform and performance budget. For a wrestling game hosted on Xisto with limited space, Three.js plus Cannon-es is incredibly efficient. You can serve everything as static files, no heavy WebGL builds. But if you ever want to add networked multiplayer (which wrestling games often benefit from), Unity’s Netcode for GameObjects or Mirror give you a huge head start. Three.js networking is possible but more DIY.

One modern trend not mentioned: WebGPU is emerging as a successor to WebGL. Three.js already has experimental support, and it can drastically improve rendering performance without the overhead of Unity’s WebGL pipeline. For a 2026 project, learning Three.js might future-proof your skills better because the engine’s architecture is closer to the metal.

For collision detection specifically, I’ve found Ammo.js (a port of Bullet Physics) works smoothly with Three.js if you want realistic ragdolls—perfect for a wrestling game. Cannon-es is simpler for rigid bodies but lacks soft body support. There’s also Rapier in Rust compiled to WASM, which is blazing fast for physics-heavy games.

Finally, don’t underestimate the value of the asset ecosystem. Unity’s Asset Store has dozens of wrestling ring models and character controllers ready to drop in. Three.js relies more on manual modeling or external stores like Sketchfab. If time-to-playable is critical, Unity wins. If you’re building for longevity and learning modern web standards, the Three.js path is unbeatable. Either way, both are viable in 2026—the diagram’s decision tree is your best guide.
