project-curator: A convenient tool to help cleaning and maintaining Unity Projects 🧹✨

Project Curator is an Unity Editor window that, based on the currently selected Asset, displays the following information: Each asset it depends on (called dependencies). Each asset that depends on it (called referencers) Very useful to know if an Asset is can be safely deleted or not.
Whether the asset is included in the build or not, depending on the nature of the Asset and its referencers (checked recursively)

Unity3D - Personal Notebook: A notebook filled with a variety of Unity-related content by a seasoned game developer.

It is especially helpful for new developers as it provides the following:
- A list of existing assets that the author typically includes in their projects.
- UI tips: Although Unity's documentation has greatly improved in terms of UI and its optimizations, this notebook can still serve as a handy cheat sheet to refresh your knowledge.
- The building process and how to troubleshoot potential issues.
- Optimization tips
- Editor tips and tricks
and many more

Improving Burst Inspector search performance

Another example how standard methods might be a lot slower due to various reasons, for instance safety checks. And how own implementation may leverage some assumptions to provide performance gains.
But as usual, always profile.

Compute Shaders in Unity: Processing transforms with GPU

The noscript is a bit misleading, it's about how to pass data to a compute shader, modify, and then return back to a C# noscript. Transforms are still processed on the main thread. But it's still a decent example how to use compute shaders.

Position-Based-Dynamics: A PBD fluid in unity running on the GPU

Position based dynamics is a method used to simulate physical phenomena like cloth, deformation, fluids, fractures, rigidness and much more. The key process in PBD is to simulate the object as a set of points and constraints. Forces are applied to the points to move them and then the constraints make sure the points wont move in a way that violates the simulation.

Terrain Scanner Effect

An interesting approach is used to achieve the scanner effect: spawn a transparent sphere with an intersection shader and scale it over time.

Improvements to Unity shader files in Rider 2023.2

TL;DR: More autocompletion in Rider when working with shaders, which is always great and should help a lot, especially developers who are new to writing shaders.

Mechanics and tricks from Platformers applied to Endless Runners to improve experience

The author describes multiple platformer mechanics and provides code samples for them. I believe such mechanics are must have in a platformer game nowadays, and I definitely gonna implement all of them in a kinematic character controller I develop for my own roguelike game with platformer mechanics.

The list of mechanics:
- Early Fall: Player descends as soon as jump button is let go ending jump early.
- Jump Buffering: When the character is already in the air pressing jump moments before touching the ground will trigger jump as soon as they land.
- Predict Ground Collision: When the character is already in the air pressing jump and there is a platform near and below, it can jump as it is already on the ground.
- Coyote Time: Jump still triggered a few frames after running off a ledge.
- Catch Missed Jumps: If a player doesn’t quite make a jump either lift them up a few pixels or change the collision mask so their feet don’t hit the wall.

Platforming Tips and Tricks

As a game developer it is your job to make the character move as the player wants, NOT how the player inputs controls. Even if you think your niche is having a very hard game that only makes it more important that your controls are forgiving.

The post also contains a playable demo with these tricks implemented.

How to instantiate a prefab in ECS?

It's interesting how such a big post needed to describe so simple action as instantiation. And it doesn't even touch the topic of using a hybrid approach, for instance to connect entity to Animator so your instantiated object can be animated using Mecanim and triggered from ECS.

SHOULD YOU DO EARLY ACCESS?

Basically the EA path is high risk, and slightly higher reward. Don’t do EA because you need “feedback.”
