Godot 3.3

Why Pearl instead of the dozens of other successful projects that maintain a stable version while working on a new version?

For those interested in Godot, but wanting console support - heaps might be of interest:

It is another, smaller engine. I would say less featureful than Godot, but I imagine there are some overlapping use-cases?

Ed: and for something quite different - dragon ruby seems a lot of fun (not free, not open source, though): https://dragonruby.org/

Yeah, FB/Oculus has quite the interest in Godot. But at the moment there is no official Quest game made with Godot yet AFAIK. So far we made it into AppLab with VRWorkout, but the store is a completely different story

Interesting. They mention porting is possible - what would that look like i wonder? Would you make your game run under both UE4 and Godot? Or do they attempt to put a layer between whatever engine you use and the actual console APIs?

It uses pixels as its units for 2D, which is the main advantage over Unity, depending on your use case (ie, it's very good for pixel perfect 2D games). If you want to move your sprite 33 pixels, you just add 33 to the translation. This also applies to physics, GUI elements, etc. You can also combine the separate 2D and 3D renderers, while maintaining 2D pixel vectors for your 2D objects, and 3D unit vectors for 3D. Yeah, there are pixel perfect cameras and so on for Unity, but it's so nice to be able to just work in 2D as if it were actually 2D. Simple things in 2D renderers like alpha handling and overdraw was slower in Unity than Godot for that reason when I last used it, since it's more complicated to render those things in a 3D engine than a 2D one (admittedly, I last used Unity properly at least a couple of years ago, may have changed).

It has parallax scrolling features built in. Small thing, but there are lots of little features like that scattered in the default tools that just don't exist in Unity without writing your own, or paying for an asset. In Godot you just drop the node in and you're away. Godot has an asset store too - where everything is free and open source, and linked to their git repositories. For example, you can add a minecraft-like voxel engine, dialog editors, a Redux-like store, shaders, new GUI elements, and so on in Godot for free, in a click, without an account, or a single webview or browser page in sight. Granted, this means that older assets may no longer work or be maintained, but the same can be said of Unity (and my experience with the Unity asset store is that half the time, nothing works out of the box anyway even when you've paid a chunk for it, and rarely does a tool just do the simple thing that it says it does, and therefore takes a bunch of work just to get the thing to play nice with your code).

The recent 3.3 release added a bunch of 2D renderer improvements such as BVH partitioning/batching for rendering and physics, vertex pixel snap on the GPU,

The only thing that Unity has over Godot in terms of 2D imo is the Box2D physics engine (Godot uses its own 2D physics implementation that, while adequate for a lot of games, isn't quite as flexible as Unity). That said, there are at least 2 Godot plugin modules that add (partial) Box2D support just from a brief Github search.

Moving away from 2D specifically - the animation player/controller in Godot is amazing - you create an animation player node, and you can then key in literally any property of any object from the editor to be animated, and draw out animations with bezier curves and so on, animating multiple properties at once, which you can then play back with a simple call to `AnimationPlayer.play("name");`. You can use a single animation to animate vectors, enums, bools, simultaneously by just drawing them into the animation editor. Last I checked Unity didn't have anything like that. You've got a complicated mesh structure with layers of materials and shaders, and you want to interpolate various properties on various materials of those mesh structures, it's as simple as creating the animation, going to the materials, and hitting the key button on the properties you want to alter.

From a general design perspective, Godot's scene tree works kind of like Unity's nested prefabs - a feature they implemented long after Godot had nailed this kind of structure, and it still does it in a much simpler and less hacky way than Unity. Everything in a Godot game is already essentially a nested prefab, without the clunk of having to distinguish between regular prefabs holding nested prefabs, or ensuring your modified prefabs are in sync, and so on. You can create simple components composed of complicated structures of nodes, save them into a new scene file with a click, and drop that anywhere else in your scene tree wherever you like, as a native and expected behaviour. It's a bit like React components in that you can very easily combine and produce new combinations of your existing work, even at runtime. You can then easily share these nodes between godot projects, or even write a simple plugin to add them to Godot's list of built-in nodes.

Oh, and all of those scene, node and resource files are just plain text files, easily editable in a text editor, and extremely friendly to VCS.

Besides all of this, if you write a game in Godot you own 100% of the source code, both your game code and the engine supporting it. No licensing, no pricing plans, no salespeople. No official support, yet the community and contributors are extremely helpful. Engine doesn't do something you want? You can patch it and recompile, and add new third party C++ modules (eg, you can add full Javascript/Typescript/Rust/D/Python/Nim scripting support this way, as well as new engine features with native speed) by dropping them in the modules folder of the engine source. There's a legendary talk at GDC by Jeff Vogel, who's been writing obscure, ugly RPGs as Spiderweb Software since the mid-90s. One of his points is that if you want to make a living writing indie games as a solo developer, owning the source code is one of the best things you can do, since 20 years down the line you can still update and compile it, remaster, and sell more copies of work you finished long ago (which Jeff has done many times, and is still now writing those obscure games and supporting his family from it). Good luck getting Unity 2020 to work, build your game, and have the license to use it commercially in 2040 ;)
