Unity-HDRP-GPU-View-Cone: View Cone, Field of View, Sight Cone - done with custom Shadow Mapping in Unity HDRP

The technique used is basically the shadow mapping. Rendering the depth texture from the eyes of the enemy, then checking which spots are visible to the player AND the enemy and only drawing on overlapping pixels. The performance cost should be like having a spotlight with shadows turned on.
Since the latest few HDRP Upgrades the system doesn't work in builds anymore. So consider this repo just for learning purposes on how to theoretically set up custom shadow mapping

Unity Production Architecture

There are endless ways of scaling your architecture without suffering, and different developers have different opinions about that. The author tried to identify practices that are easy to follow, simple enough, but still result in scalability.
The book is not finished yet, but 3 chapters are available already.

Text To TextMesh Pro Upgrade Tool for Unity

Helps you upgrade the Text, InputField, Dropdown and TextMesh objects in your projects to their TextMesh Pro variants. It also upgrades the noscripts so that e.g. Text variables in those noscripts become TMP_Text variables. Then, it reconnects the references to the upgraded components (e.g. if a public variable was referencing an upgraded Text component, it will now reference the corresponding TextMeshProUGUI component).

Unity Shadow Volume Generator (Stencil Shadows): Library for generating sharp shadow volumes in Unity3D.

Shadow volumes are recognized by the CRISP and ACCURATE shadows that they cast. It essentially finds the outline of an object from the lights perspective, and then creates a mesh that casts into the scene.

Practical Optimizations

This is a long video, but it's worth watching. The speaker is a great engineer who shares an example of optimization using DOD (Data-oriented design) in Kerbal Space Program 2. Obviously, this optimization technique is not suitable or needed in every game, but when it fits, it gives amazing results.

Unity Image Loader: Asynchronous image loading from remote or local destination.

Features:
✔️ Async loading from Web or Local ImageLoader.LoadSprite(imageURL);
✔️ Memory and Disk caching - tries to load from memory first, then from disk
✔️ Dedicated thread for disk operations
✔️ Avoids loading same image multiple times simultaneously, task waits for completion the first and just returns loaded image if at least one cache layer activated
✔️ Auto set to Image ImageLoader.SetSprite(imageURL, image);
✔️ Auto set to SpriteRenderer ImageLoader.SetSprite(imageURL, spriteRenderer);
✔️ Debug level for logging ImageLoader.settings.debugLevel = DebugLevel.Error;

unity-hierarchy-folders: Specialized folder objects for Unity Hierarchy.

With big scenes you might want to have game objects organized in some way. However using just empty game objects for it might lead to performance issues as the engine won't be able to parallelize transforms processing, as Unity manages them on hierarchies level.
This tool helps prevent these issues by removing all overhead during the build process.
