Abandoned A-Frame

-

 As I continued building more complex interactions, A-Frame’s limitations became increasingly apparent. It simply was not designed for the level of multimedia interactivity I had in mind.

Video Texture Mapping: Poor Support

One major creative goal was to play videos directly on the surfaces of 3D models. I envisioned turning parts of my models into living, dynamic canvases using video textures. However, A-Frame does not support this natively.

  • The <a-video> element only supports flat, rectangular planes—not curved or complex geometry.

  • Trying to assign video elements as materials requires breaking through A-Frame’s abstraction layer and manually injecting logic via Three.js.

  • I faced issues with auto-play restrictions, decoding failures, and texture mapping bugs.

  • Even advanced tricks like drawing the video to a canvas and converting that to a texture failed due to CORS restrictions and browser policies.

This showed me that A-Frame is not well-suited for complex media applications involving real-time video manipulation or shader-based texture dynamics.

User Interface and Performance Bugs

Aside from model and media issues, many other technical problems surfaced:

  • Navigation buttons occasionally failed to respond due to input misfires or autoplay policy conflicts.

  • Background music would stop playing midway through or fail to loop, particularly on mobile devices.

  • On mobile, layouts became distorted, and touch interaction was inconsistent.

  • The browser console constantly threw deprecation warnings (e.g., .useLegacyLights is deprecated), adding to the sense of instability.

Even when I tried resolving these issues by incorporating raw Three.js functions, A-Frame’s encapsulation made it difficult to intervene. The framework simplified development but at the cost of flexibility.

Why I Decided to Move On

At this point, I had spent over a week trying to resolve issues that I originally assumed would be trivial. While A-Frame excels in creating quick demos or static VR experiences, it lacks the power, freedom, and performance required for building real, interactive, and media-rich environments.

For example, my project required:

  • Dynamic model swapping

  • Complex scene transitions

  • Real-time video textures

  • Interactive UI overlays

  • Scene loading logic with user input handling

A-Frame’s architecture made all of these difficult, if not impossible, without deep workarounds. This led me to pivot toward Unity, where I could achieve greater control, performance, and interactivity—even if the learning curve was steeper.

Creating a Portal System with Player Collision in Unity

-
Image
It all started when I randomly thought: Wouldn’t it be cool if I could make a scene where I walk through a portal into another world? Like literally, walk into one space and boom — you're somewhere completely different. I immediately thought of the game Portal , which has those awesome sci-fi doors you can go through and see what’s on the other side. So, that was my goal. Starting with What I Know: Modeling in C4D Since I’m already familiar with Cinema 4D , I figured I’d build the portal frame and some basic scene geometry there. Way faster than modeling inside Unity, and I could be more creative with the shapes. Once I had the basic portal built in C4D, I exported the models as and imported them into Unity. Luckily, that part was pretty smooth (just make sure your scale settings aren’t messed up!). .fbx YouTube to the Rescue 🎥 Then I thought, Has someone done this before in Unity? (Spoiler: of course they have). I searched YouTube and found a super helpful video: 👉 ...

Three Types of Scene Project

  After finishing my working portal with the smooth camera-following shader (yay!), I realized I still needed to build simpler prototype versions for my teacher — something quick and light to show how scene transitions could work, especially for computers that might not handle 3D and shaders well. So I made three different versions of scene switching, from super basic to silky smooth: Version 1: Boring Button Click (2D Image) This was the absolute easiest — I just: Made a simple UI button in Unity. Used on . SceneManager.LoadScene() OnClick() Put a 2D image background behind it. Not much interaction, but it gets the point across. You click → it loads a new scene. Honestly… kinda boring 😅 But it works, and it’s super light on performance — good for basic demonstrations or weaker computers. Version 2: Player Touches a Door → Transition This one was already more fun: Built a 3D door model in C4D and brought it into Unity. Placed a trigger collider in ...
