My personal experience. Unity vs Unreal

This is intended to answer a question Casey Muratori had on twitter about why would anyone choose Unity over Unreal. The short answer is, I have no clue. Well, I kinda do know why you WOULDN'T choose it, so maybe I'll tackle it that way, pros/cons. Read on.

There's a few pros I could think for Unity:

  • Their text-based asset serialization which makes collobration work and resolving conflicts much easier. Unreal's assets are all binary and it's really built well for Perforce, if you're more than a handful of people working together not using Perforce (e.g. git) you'll have a less of an idea time.

  • Their undo/redo system I found is a lot more graceful/lightweight than Unreal's. Undoing in Unreal sometimes doesn't work reliably or go back a dozen entries in history, and just reverts back your selection state and is a bit intrusive (not sure if that was imporved in UE5)

  • Their animation editor (for me as a non-animator) I found was friendlier and easier to work with

  • The profiler is nice and very easy to us

Guide to User-Centric CRUD using Express & Mongoose

Intro

Typically, logged in users interact with an application that results in data being created, updated and deleted.

In almost every case, the application's code will need to ensure that the logged in user can only update/delete data created by them, not the data of other users.

Rendering Engine Development

1. What does the Rendering Engine Need?

  • Rendering Engine
    • Support for Multiple Graphics APIs : OpenGL | Vulkan | DirectX12 | DirectX11 | Metal
    • Content Export Pipeline : Create Maya/Max Plugins to export meshes based on Renderers needs. (Assimp Commercial Licence -> Pay)
    • Texture Compression Libraries
    • Material System : Artists Configure shaders, textures, parameters to import in game
    • Game-side Manager of Models/Materials/Lights
    • Good Visibility System (Frustum/Occlusion) (VisibilityBuffers?)
    • Multi-Threded Submission System to reduce cost of submission to GPU
  • Lighting/Shadow Rendering System

Using Dat with a github.io domain

https://i.imgur.com/akOrIOq.png

My personl site is hosted at hashbase.io (link) so that you can access it via dat and https. My canonical dat url is dat://pfrazee.hashbase.io.

Before I used hashbase I used Github Pages, and today it dawned on me that I can have dat://pfrazee.github.io work too. It's pretty simple if you know the dat dns spec.

All I had to do was add /.well-known/dat to my site (click to view). I put the raw dat URL of my site in that file, along with a TTL.
