#UnityTips 1:

🎨 Pixel Art can look weird in Unity if you don’t import it correctly. Here are some settings you can change to make your pixel art look better 🧵

@samyam_youtube

When importing pixel art, make sure to pay attention to the resolution of your art.

Ideally, the size should be base 2, for example, 16x16,32x32,64x64,128x128, however, it is not necessary. Make sure it is a PNG with a transparent background. Tiles by @KenneyNL. (1/8)

In the import settings, select Sprite and then set the PPU (Pixels Per Unit) to the size of your pixel resolution. For example for a 64x64 image, you will put in 64. This is important for the pixels to be scaled correctly. (2/8)

Slicing ANY mesh (visual) with 2 lines of HLSL.

if (dot(worldPos - planePos, planeNorm)) > 0.0
discard (the pixel, or clip alpha) ⭕🌠

Mesh back faces can be stencil masked with the plane to 'project' a texture as the clipped surface.

#unitytips #unity3d #gamedev #indiedev

Here's the shader graph version (ASE). ✨
Just one line if you inline the discard/clip. 😁

This part is important for the texture projection (actually stencil masking).

#UnityTips: 🔥 Fluid 'simulation' trail shader. 🫧

Inspired by a #b3d node animation. [U]V gradient masks control the colour/alpha/width over trail. ✨

Here is a list of free, open-sourced #Unity packages that i’ve found very useful. Most of them are oriented to improve productivity. 🧵[1/X]
#madewithunity #unitytips

1. Serializable Interface by @Chrusb, github.com/Thundernerd/Un…
This package allows you to serialize interfaces and select, in the inspector, a game object, asset or even C# classes that implement that interface.🧵[2/X]

2. NaughtyAttributes by @DenisRizov, github.com/dbrizov/Naught…
This one is pretty well known. It provides a lot of attributes to modify the looks of the inspector. Some of the most useful (IMO) attributes are shown in the images.🧵[3/X]

Unity for Games

@unitygames

I wanted to finish this Takeover with something I get asked a lot: how do I set up my characters in Unity? So here is how to create, rig and animate simple characters all in Unity! I threw together a cute robot for this occasion 🤖

#UnityTips @AlexStrook

It’s easy to create simple characters with basic primitives. Probuilder is useful too! For this character I used 4 models that I duplicated, scaled, rotated around to create this cute robot. It helps to think about animation at this step!

Once the model is done, I create empty gameobjects, and place them where the joints would rotate. These are the objects that will get animated, it’s important to name them correctly for animation! Using front/side views helps with precise placement.

@TheZombieKiller

#unitytips Let's talk singletons. Love or hate them, they're an extremely common pattern in Unity games—for good reason. The engine itself even has some built-in! (kinda)

However, I often see developers implement the pattern in very error-prone or overly-complex ways.

(thread)

Consider the following example. It is representative of what you will typically see in tutorials and various other educational resources for Unity:

Simple as it may be, this has a number of glaring issues:

• If a singleton needs to access another singleton, it cannot reliably do so in Awake.
• The component needs to be manually placed in every scene.
• You need to manually implement the pattern for every singleton.

George B. Green - making BoneToPix

@GeorgeB_Green

Hey #IndieDevHour! 👋

Today I added dithering to the Pixel-Light 💡 shader for #BoneToPix

Mini-tutorial below 👇🧵

#GameDev #IndieDev #PixelArt #UnityTips

Previous thread with the start of the tutorial for per-texel cell lighting:

https://twitter.com/GeorgeB_Green/status/1484984312839688193?s=20

The main trick for this one is doing a 1:1 mapping of texels in our main texture to texels in the dithering lookup

Then bring it into the [-1,1] range and scale it.
The sampled offset is used in the CellLookup

Make sure your dithering lookup is set to wrapped for this to work

🔽How I made this cool "LED panel" effect in Unity
⚠️Disclaimer: I have no idea what I'm actually doing

#madewithunity #unitytips #shader #vfx #unity

Now, the easiest way of doing this would be with a simple scrolling texture. However, if you need many different messages, you need many different textures, and file size can be a problem if you are targeting mobile platforms (which I'm doing)

So instead, I'm only going to use one "high res" mask texture, and keep all the other ones with a really small resolution, which scales better the more textures you need (I think that makes sense?)

Hello Unity fam!👋
My name is Fabian Willis (@FabianWillisArt), 3D Artist from Atlanta, and I will be your flight attendant on behalf of #Unity3D Airlines. Please ensure your electronic devices are not set to airplane mode as I’ll be sharing some #unitytips & tricks with you 🧵

Some info about me:
📌Been learning 3D w/ Blender since 2018 & Unity gamedev since 2019
📌My art evolved from flat creations to low poly cel shaded characters & enviro design
📌My inspo comes from games I’ve played in my childhood: Zelda, Kingdom Hearts & Final Fantasy 9 & 10

.@HofmannDev & I (@FabianWillisArt) are working on a game like classics Jak & Daxter, Wind Waker, & Majora’s Mask. It features a main character called Demi, has a compelling plot, the gameplay of an action-adventure, & the mechanics of a 3D platformer👇

Unity for Games

@unitygames

In case you didn’t know, there’s a very fun way to get more bang for your buck when using particle systems and custom shaders: custom vertex streams!

Let’s take a look at what these are, and how we can use them for more advanced particle effects! 🧵

@HarryAlisavakis #unitytips

@HarryAlisavakis As you already know, rendered models in Unity are made with triangles which consist of vertices. And vertices hold all essential information regarding these models, like their individual position, their UV coordinates or their vertex color!

The cool thing is that we can add any sort of arbitrary data to our vertices and use it in our custom shader however we like ✨ That’s what custom vertex streams in particle systems allow us to do: pass particle-related information to our vertices that we can use as we please!

Happy #unitytips Tuesday! Thought I'd share a 🧵 on something that should be super helpful for VFX artists!

It's about that "BlendAdd" blending mode, discussed at the famous Diablo VFX talk ✨

Let's go~

#gamedev #unity3d

With Unity's "Standard Unlit" particles you have a "Rendering Mode" dropdown that gives you the options you can see below. Most of them are easy to guess what they do, but "Fade" and "Transparent" don't really communicate their differences.

It also doesn't help that the standard object shader also has these modes but act different; "Fade" completely fades the object away when alpha is 0, while "Transparent" keeps specular reflections when alpha is 0. That's not the case with unlit particles though (obvs)

@LotteMakesStuff

Sup Friends! Lets do some Editor Scripting! theres a whole bunch of cool tech unity have added over the last year or so thats SO worth knowing about. Lets buildsomething with...

- [SerializeReference]
- TypeCache
- SerializedObjects
- ReorderableArrays

exciting! #UnityTips

So heres the dream. We want to have a list of *things* that we can assign in the editor, and then at runtime we want to iterate though that list and do some *stuff*. its a simple idea! but untill recently, its been HELLA hard to implement something like this in unity!!

So lets look at the first part of that problem. we want a list of stuff! and stuff to go in the list! and a (hacky) way to get stuff in the list!

So, what we have here is simple, we got a MonoBehvaiour that has a List of KindOfStuff objects in it.

Let's talk about @unity3d, and the execution order of its event functions—such as 𝚂𝚝𝚊𝚛𝚝 and 𝚄𝚙𝚍𝚊𝚝𝚎.

Trust me when I say that ...IT'S WAY MORE COMPLICATED THAN YOU THINK. 😬

#gamedev #unitytips #madewithunity

🧵👇

🔹𝗙𝗶𝗿𝘀𝘁 𝗦𝗰𝗲𝗻𝗲 𝗹𝗼𝗮𝗱

1⃣ 𝙰𝚠𝚊𝚔𝚎: always called before any 𝚂𝚝𝚊𝚛𝚝 & after a prefab is instantiated

2⃣ 𝙾𝚗𝙴𝚗𝚊𝚋𝚕𝚎: called just after a 𝙶𝚊𝚖𝚎𝙾𝚋𝚓𝚎𝚌𝚝 is enabled (including when loaded, created, or a 𝙼𝚘𝚗𝚘𝙱𝚎𝚑𝚊𝚟𝚒𝚘𝚞𝚛 script is added)

🔹𝗕𝗲𝗳𝗼𝗿𝗲 𝘁𝗵𝗲 𝗳𝗶𝗿𝘀𝘁 𝗳𝗿𝗮𝗺𝗲 𝘂𝗽𝗱𝗮𝘁𝗲

3⃣ 𝚂𝚝𝚊𝚛𝚝: called before the first frame update. This happens only if the script is enabled. 𝚂𝚝𝚊𝚛𝚝 can also be made into a coroutine by changing its return type to 𝙸𝙴𝚗𝚞𝚖𝚎𝚛𝚊𝚝𝚘𝚛

@LotteMakesStuff

Sup Friends! lets build an editor tool together, we haven't done that in AGES! I need to preview a Texture2D in the inspector, and theres no easy way to do it without making a custom editor. Lets fix that by making a PropertyDrawer! Its going to look like this #UnityTips

If you dont know, Property Drawers let us customize the inspector by adding a Attribute tag onto a property. As an example, lets add a Range drawer onto the Face index in my example code. Range is built into unity and is a good demo of the power we get from PropertyDrawers~

So lets make our own! The goal is to make the texture thats assigned to the SelectedFace property draw in the inspector. We need to make a new PropertyAttribute that triggers the editor to draw the texture field exactly how we want.. Lets add one called TexturePreviewAttribute!

After using @unity3d for almost 10 years, I want to share the TEN small features that are really helping me develop games faster.

Starting with my favourite... 😎

1⃣ Inspector Maths

You can write ACTUAL mathematical expressions in the inspector! 🤯

Check the other ones!

🧵👇

2⃣ Animation Curves

Unity supports a super easy way to create smooth paths through ANIMATION CURVES. Perfect for blending & animating properties.

Creation:
public AnimationCurve Curve;

Usage:
float x = Curve.Evaluate(t);

#unitytips

docs.unity3d.com/ScriptReferenc…

3⃣ Gradients

The equivalent of AnimationCurve for colours is Gradient. You can use it to create and sample smooth gradients.

Creation:
public Gradient Gradient;

Usage:
Color c = Gradient.Evaluate(t);

Unity NavMeshes! We've recently switched to them from our old custom A* pathfinding solution, and we've found it super fast, robust and accurate. Here's a few #UnityTips to help you make the most out of the NavMesh API
(thread)
#madewithunity

NavMeshAgents are great to get something working quickly, but they're a bit limited & prescriptive when dealing with finely tuned movement & steering. Instead, we use CalculatePath, passing the result to our own character controllers. No agents necessary!
docs.unity3d.com/ScriptReferenc…

Consider using NavMesh.SamplePosition instead of just passing your source and destination positions directly! This way our AI can create a best effort path even if the player or enemy positions aren't directly sitting on the NavMesh itself
