News: About the NVIDIA DLSS 2.0

This past week, NVIDIA announced an update to its Deep Learning Super Sampling technology, aptly dubbed DLSS 2.0.
Deep Learning Super Sampling named DLSS is an NVIDIA RTX technology that uses the power of AI to boost your frame rates.
DLSS essentially takes lower-resolution imagery, and intelligently upscales it to looks like native, higher-resolution output.
Performance was universally improved to varying degrees since the game was being internally rendered at a lower resolution, but image quality wasn’t always optimal and sometimes resulted in unwanted artifacts.
The old DLSS 1.0’s effect on game visuals and performance was a mixed bag, that varied from title to title.
The new DLSS 2.0 comes with DLSS 2.0 improved the quality, balanced, and performance by leveraging the Tensor cores available in its GeForce RTX-series GPUs.
Let's see one example:

Unity 3D : About VFX Graph.

The official webpage of the VFX Graph for Unity 3D comes with a short intro.
The install steps can be seen on this webpage.
I started today to follow one video tutorial about fire and smoke from youtube channel named Brackeys.
This video tutorial can be seen here:

Some conclusions about my test with an old video card:

• you need a good video graphic card;
• you need a unity version with Package Manager;
• I found some new changes using with the Unity 3D version 2019.3.5f1;
• many changes in the 
• the one is the Output Particle Quad with many changes into variables;
• I cannot set the TotalTime, this crash it all;

The result is this:

The settings for this smoke effect using the Visual Effect Graph Asset can be seen in the next image:

Partsim online circuit simulator.

PartSim is a free and easy to use circuit simulator that runs in your web browser.
I create today my account to see how better is this online tool.
You can build, test and simulate your e with a SPICE Simulator, AC/DC/Transient Sims and Waveform Viewer.
The Arrow Integration lets the PartSim include an integrated Bill-Of-Materials manager that lets you assign Arrow Part Numbers to your models.
You can see many examples on the official website:

• Bipolar Differential Amplifier;
• Simple CMOS Inverter;
• OpAmp Transient Full-wave Rectifier with Smoothing;
• Capacitor;
• Passive Low Pass Filter;
• RC Charging Circuit;
• Differential Amplifier

You can see many video tutorials on the official website:

Firebase and Unity 3D.

Even is an old feature the Google team comes with this new option for the new developers and show how to use them.
The goal is to add Firebase to your Unity project.
The Google webpage tells us:
Power up your Unity games with our Firebase Unity SDKs. To show how easy it is to plug Firebase into your Unity project, we made a sample game, MechaHamster, that you can download from GitHub, the App Store, and the Google Play Store.
... and show a short video about how can be used to create a application named Mecha Hamster, see the GitHub webpage project:
You can import the project with GitHub commands:

https://github.com/google/mechahamster.git
...

The game is pretty funny, see the Youtube channel from Firebase:

Paladins is free on the Epic Games Store.

This game is for free and is named Paladins.
I play this game online and is a great game.
The team from the Epic Game Store tells us:

Unity 3D : Fix error "Failed executing external process for 'Bake Runtime' job."

If you want to remove the error show on the Unity 3D console:
Failed executing external process for 'Bake Runtime' job.
... then go to Main Menu - Lightning - Settings and uncheck the Auto Generate checkbox.
See the screenshot shown below:

Unity 3D : Use Quick Fix on Visual Code for Unity and Linux.

Because I don't use Unity 3D with Linux and Visual Studio today I solve another issue for the development area.
This is the quick fix option for Visual Code that helps the user to add source code.
For example, you can add source code for the implement an abstract class PlayerBaseState:

using UnityEngine;

public abstract class PlayerBaseState 
{
    public abstract void EnterState(PlayerController_FSM player);
    public abstract void Update(PlayerController_FSM player);
    public abstract void OnCollisionEnter(PlayerController_FSM player);
}

Create a new C# script named PlayerIdleState. The script needs to be changed into this source code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    
}

Select the PlayerIdleState and use these keys: Cmd or Ctrl and . (the point key) .
This will show a menu named Generate overrides... and help the developer to generate the new code:
The result is this source code with all new override for each of methods of PlayerBaseState class:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    public override void EnterState(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override bool Equals(object obj)
    {
        return base.Equals(obj);
    }

    public override int GetHashCode()
    {
        return base.GetHashCode();
    }

    public override void OnCollisionEnter(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override string ToString()
    {
        return base.ToString();
    }

    public override void Update(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }
}

SpriteStack online tool for sprites with 3D features.

This is an awesome online tool to create sprites for your game named SpriteStack.
You can find this online tool on this web page.  
SpriteStack is a 3d pixel art editor based on the sprite stacking technique. Similar to voxels it's a fun and simple way to draw low-resolution 3d objects that can be later used in games or submitted to the online gallery.
The tool is easy to use and the output is good.
I use the free preview of Sprite Stack Studio but you can get one of the options to unlock all features from Steam or Itch.io website. If you want to have full online access to the editor and exporter at a low price then use the Patreon website with just 2$ per month.
I find a good tutorial on youtube but you can see the videos from help webpage:

Unity 3D : Setup Visual Code for Unity and Linux.

The tutorial for today will cover the settings of Visual Code and Unity into a Linux distro.
First, you need to install the Visual Code into your Linux distro.
You need to have the Unity 3D software working well into the Linux distro.
Open the Unity 3D software and create a new script using the main menu: Assets - Create - C# Script.
Open into Unity 3D from the main menu: Unity - preferences - External tools.
Select the Visual Studio Code like into the next image:

Double click on the newly created C# script.
This will open the Visual Studio Code and will ask you to install the C# feature using the Install button, see the next image:
 
This will install the C# extension for Visual Code.
The last step is the install of DotNet for Visual Code.
Use the button with the name Get the .Net Core SDK to install the Net CORE.
This will redirect to a webpage where you find the commands to install for your Linux distro.
After these steps, you can use Unity 3D software with Visual Code.
