Changing this to the lowest value (0.01) makes suggestions always appear instantly for really quick coding

I'm continuing my tip series with some more tips (ended up stopping it before since I got busy with some projects). Will have a goal of having tips at least until the new year

​Hackers have used new GodLoader malware exploiting the capabilities of the widely used Godot game engine to evade detection and infect over 17,000 systems in just three months.

Hi everyone! I recorded this video outside my usual weekly schedule because it doesn't focus on any specific shader. However, it's a topic that's useful to explain, as not all details may be clear from the official documentation. The video will cover working with images in shaders, particularly different types of filtering.

Before the game had an abstract "grab" mechanic. But having a physical tool seems more immersive (Skeuomorphic Design).

Coding that is shocking simple: Trace a ray to the object to grab, get the position, and apply a force on that object from that position towards the player.

Hey everybody! There are many ways we can adjust or enhance what we want the player to see on the screen while playing our game. I’ve already discussed several post-processing algorithms in previous videos, and this time I’d like to add another to the collection, which is quite computationally inexpensive and is something between edge detection and converting a color image into a monochromatic sketch. Let’s take a look at it.

I have heard many times that if statements in shaders slow down the gpu massively. But I also heard that texture samples are very expensive.

Which one is more endurable? Which one is less impactful?

I am asking, because I need to decide on if I should multiply a value by 0, or put an if statement.

Hi everyone! Do you remember the shader I unoriginally called the Line Effect Shader and published a tutorial on creating it about nine months ago? Today's effect will be somewhat similar, with some horizontal structures twisting around and creating the impression of something liquid or almost plasma-like. Let’s take a look at how it’s programmed.

I and a few friends worked on this as a passion project. We hope you'll enjoy it!

I'm so happy about how this script that generates a roller coaster track from a Curve3D turned out!

You can find the code on GitHub.

Be sure to download track.gd, track_generation.tscn and meshes/track_sleeper_rollercoaster.res and fix the path to the mesh on the code.

The roller coaster will be part of my game horror Delta Park , adding to the creepy atmosphere.

Hello everyone! We continue the series of effects that we can apply to a selected texture or even the entire screen. This time, we will create a simple effect of breaking an image into hexagons, shifting the crop in each of these tiles, and the final composition of the entire image or, conversely, the decomposition, which can be quite a useful function.

Hey everybody! This time, let's try something really simple, something that works more as a one-time effect, or an exercise for understanding some of the algorithms we often use in shaders. And who knows, maybe even such an unusual effect could find a place in some extravagant game.

I posted this question on the godot forum, but that has been overrun by bots like crazy, it's all random characters, so probably some AI.

I want to edit the text of the current script editor without modifying the internal undo-redo of the editor.

So essentially I want this to be possible:

1. User writes some code
2. Program modifies it, maybe imroving the formatting and such...
3. Program then reverts to previously written code
4. User is able to undo their last code addition, without the programmatically inserted stuff to show up as the last undo-step.

Hey everybody! As a complement to the shaders we used to generate rain or a star field, we will create some nice snowfall. It's true that I have already programmed snow once, but that was in a 3D scene and with particles. This time, I'll use a 2D shader, but with a nice spatial effect using several layers, as you can see in the background right now. Let's get to it.

I want to integrate the online documentation a bit nicer into the editor itself. Is it somehow possible to query that page and get the contents of the searched-for entries?

Best case would be, if we can get the queried site content as JSON, that'd be nice, but very unlikely I think.

Godot 4.2.2

The tools/scripts available in the engine dont seem to work.

Godot Whisper uses openCL, which doesnt load on android. It works just fine when i run the program in the godot editor on my computer, but gives a black screen when exporting to android.

SpeechRecongition (script/tool available in the godot asset lib) kind of works with android but you need to use C# and my project is using gdscript.

Speech2Text is just using godot whisper i think, so same issue with openCL.

Im trying to make a mobile app that takes user voice input as an answer to a prompt and judges correctness. (Kids game where animal images are presented for the kids to guess the name)

Any recommended paths forward? Id rather not abandon android. Im going to research how hard it would be to create my own plugin for godot... or maybe using C# is the path of least resistance... Maybe i should look at other development platforms like android studio to interact with androids/google's built in voice recognition?

Hi everyone! Let's improve the Vertical Drops shader. As I promised at the end of the corresponding video, we can achieve an entirely different effect if we convert the algorithm into polar coordinates and make a few minor adjustments. Yes, we will create exactly what you now see on the screen, which can be used in the game as a hyperspace jump or warp speed acceleration. Let's get to it.

Here's a tutorial I wrote on using components to help keep your code organized.

(this is my first post on lemmy, I hope this works like I expect it does. critique and advice are very welcome and appreciated)

fennecs 🔗

Hello, I'm tiger (aka jupiter), and since earlier this year I've been working on a free, libre, and open source Entity-Component System in pure C# that aims to minimize boilerplate and dependencies, works without code generators, and give decent flexibility and performance.

Who is it for?

ECS are an architecture to apply game or other logic to large numbers (ballpark: tens and hundreds of thousands) of objects or actors in an interactive game or simulation, and ECS libraries usually enable expressive composition that go beyond the the intrinsic optimizations of keeping data close together in memory.

fennecs is lightweight and works well with Godot 4.x, The NuGet package is going into its 0.6.0 release soon (about 20 releases so far - see the roadmap)

fennecs is made to operate in just about any sufficiently advanced .NET environment (.NET 8 or later), sadly this precludes using it with Unity for about another two years - but it was created after I spent around five years working with DOTS and coming to the conclusion that it is just too heavy on boilerplate for small teams or solo developers.

There are two simple demos for Godot, a demo for the Stride engine, and when I or one of the other contributors get around to it, demos for raylib_cs, Flax, MonoGame, and others are coming, as well as more demos for Godot.

Possibly ShapeEngine and especially Murder Engine are first in line, though.

What would I like?

Easy - I'd love to hear your thoughts or questions about it if you find the time. It means the world to me to hear other viewpoints or discuss features and contributions with the wider public.

Performance?

Funny you should ask. Everywhere I post, somehow with ECS this appears to be the first question.

Even though top performance isn't the focus (minimum boilerplate is!), thanks to its compact memory layout, fennecs is doing quite all right in Doraku's synthetic C# ECS benchmarks; of which you can find an excerpt on fennecs's github. Performance hardliners can rest assured that another optimization pass comes with the 0.7.x release cycle, after the SIMD interfaces are made available.

Unique traits

fennecs is relational, allowing grouping entities by data-backed relations with other entities (bob owes alice) that are automatically cleaned on entity despawn; by link objects (in physics world P); and soon by arbitrary typed secondary keys (version 0.6.x).

Its Stream Views allow code to access the contiguous storage components are stored in in various ways (including just the raw memory to submit to GPUs or game engines),

Batch operations can modify whole groups of entities or components at once, in a fast and intuitive way.

The SIMD operators currently in development are likely to keep fennecs at the forefront for a wide variety of typical tasks, such as integrating positions and accelerations, matrix transforms, increments, etc.

SIMD ops internally use AVX2, SSE2, and AdvSIMD intrinsics to vectorize their operations where possible, and more complex operations can be composed by sequential ops.

This field is where fennecs' "low boilerplate" design goal doesn't clash with actual high performance and systems programming, and it is great for the optimization stages in game development.

Each release has close to 100% unit test coverage, and because it's pure C#, debugging, inspection and refactoring tools work very well with it.

One last, hidden advantage of being pure C# is that fennecs keeps its data in the .NET domain. Potential performance drawbacks of this are compensated very well by having to marshal function calls and component data back and forth much less frequently than many native-code ECS with C# bindings would.
