Making a Minecraft Skin-Grabber in Unity

Welcome to PolyMars, a channel focused on game development in Unity!
In this video, I explain how I used the Minotar API to retrieve any user's Minecraft skin and display it on a 3D player model in Unity.

Just a quick coding tip. Avoid having duplicate code. If you need to copy and paste 2 idential pieces of code then its most likely better to put it into a function

[@p529.]

Its actually because minecraft skins can have 2 layers on the head (maybe on even more body parts but im not sure) so the cap is just not displayed

[@erxer1]

I don't know if you've updated the code (or models) yet, but many skins have extra layers that more or less float above the existing model. Examples of that would usually be hats or hair on the skin.

[@IdaeChop]

Deadmau5' skin

[@celdaemon]

@@IdaeChop No, he has a special model only for him and does not use extra layers

[@ryan-levy]

@@celdaemon Haha, actually it's not a model, it's basically just 2 cubes rendered over the basic player model, in the code (using Yarn mappings) this is referred to as a feature renderer, it's similar to the rods that float around blazes.

[@celdaemon]

@@ryan-levy I know, but those cubes are a model.
Seriously it is referenced in mc source code as a model and is rendered in opengl as a model

[@ryan-levy]

​@@celdaemon It's a model part but not a model itself, if it were a model that would imply it would have some sort of outside file to base it's mesh on, but it doesn't. It's rendered using custom wrapper code that creates a cuboid using a few floats.
this.ears.addCuboid(-3.0F, -6.0F, -1.0F, 6.0F, 6.0F, 1.0F, scale);

[@icedmorning7610]

This reminds me of when I was quite a bit younger and believed that if I used a skin grabber it would permanently take the person’s skin and give it to me. I wasn’t the sharpest tool in the shed.

[@Akab]

i would've used the mojang api because you can check for exactly those things, like "is the model slim or not" or "is it using the old skin model" also the pixel check is not always good because you could still have a slim arm player model with a broad armed texture in the game but not really in your system!
I know i'm complaining at a high niveau so i'm sorry for nitpicking! ^^

[@dom_the_whale5140]

bro this dude deserves more subs

[@hazy6932]

the thing about the transparent pixel is actually not always gonna work. when importing a skin, the launcher asks which version the skin is, because it doesnt use the texture to figure it out, meaning some people use skins meant for larger arms with the model of the skinny arms. other people accidentally draw over where its supposed to be transparent, so there are chances that pixel might not be transparent. idk if its possible to ask Minecrafts servers if the skin has skinny arms though, so this is a good enough solution

[@Nick_DoesStuff]

so. buddy the first statement is worng it will always work it dosent matter if its set on the wrong model in the launcher it checks the texture for that and all of the skin creators always use some 3D skin tool to draw their skins.

[@hazy6932]

I'd recommend adding support for the jacket/helmet. I have made a version of this in godot that supports jackets which is complex but neat

soo its the creator of fnf modding plus hmmmmmmm

[@imnotasher4892]

your videos are great1

[@DarinBills]

Thats awesome

[@nulcow]

The fastest way to get a complete Minecraft model template is to create a new skin with Blockbench and use the "convert project" option to convert it to a generic model.

[@gavintantleff]

I have a tip for this. You can use the Mojang API directly (username to uuid, then uuid to skin), and you can get information like whether the player uses an Alex (slim) or Steve (not slim) skin.

[@mtgamekid2510]

Good to know!

[@turnipaitor]

Imagine minecraft story mode like this 🤯

[@kate_isawesome1207]

LdShadowLady is good.
Spiders are bad!

[@whaoooyipeeee1643]

Nice

[@realstulu]

Mimecraft have a feature that let you make bigger skins by turning on jackets or hat.
Maybe you can add a butten that change between the both types

[@doublbot]

fix your spelling

[@mo-s-]

Idk, but you can make the pixel you use for detection transparent in normal models too

[@NoelJasik]

Now my minecraft clone will be powerfull!

[@memetech-]

This also supports the new “slim armed” option VS “classic” skins, plus the old format. However, did you compensate for skins with tramsparent pixels on them? (Mojang might be removing them but still) and if you are are you supporting top-layers?
Test account for that could vary, but I currently am replacing blakertines skin from all black pixels with skin on top to skin with longer clothes on top. Switching between top and bottom layer, VS both, could also work too!

[@kate_isawesome1207]

I like slim arms better. Since slim arms are for girls only.

[@mimikanahd1638]

We are doing a military roleplay with skins as like intelligence or something so this thing is key to winning

[@TomTheCasual]

If I remember right a musician called something like deadmau or something like that got a exclusive skin from notch himself with different proportions to that of any other skin to this day

[@lusacan1406]

thx it rly helped in my cringe funny wowie game thanks thanks

[@renegadegirls]

[@Hi1mMe]

[@miwiki6]

what

[@jan-olemichael4967]

Why didnt I find this when i needed it

[@chickennugget481]

you should add support for the second skin layer

[@samdabugg]

oh my gosh is that the music from "push the button"?

[@FBlockLeymann]

Are capes compatible?

[@wagyourtai1]

why use minotar api when you can directly use mojang's? also technically the alpha of any pixel can be 0, it just displays as black when mapped if it's not an upper layer... the actual minecraft API tells you whether it's using the "slim" model

[@Darthcat1204]

Does it need to be in Java or does it work for bedrock too. I want to download my bedrock skin to bring it into Java

[@indonesialovah]

Would be cool if you added a way to test the skins in the project itself before downloading with a way to see all animations or walk around in the skin in a flat world. And being able to convert your skins to any format.
And also having the 128x128 format (the 128x128 format is not supported by pc skins, but you can connect your pc with your phone and drag the skin from the phone to the game files.) and also having a button which automatically makes you wear the skin and if any device is connected it would say the device name and say if you want to transfer it to both,none (but why would you),pc or decice. It would basically locate the game and add ut to the custom skin list or you being able to add it. And maybe on pc doing the same with the launcher. Just to make it unique.

[@kate_isawesome1207]

Yeah! So annoying!

[@lordnordsucc4082]

I watched the same videos for making a model, but for some reason my model did some weird ass morphing when posing. Also since I was using the newest version things were so confusing for me.

[@09kingarthur]

Maybe you could add support for this he outer layer on some skins.

[@SalvoGamerYT1]

um there is a problem,what happens if skins have capes integrated?

[@peatral]

Well the way without using the minotar api would be to fetch the player uuid for the player name using mojangs api, then fetch the profile data via the uuid, decode the base64 string that holds the skin information and voila, you got the image url and the information wether it is an alex or steve style skin. Furthermore, you can tell from the hash of their uuid if its a alex or steve skin if no custom skin is set.

[@Kin-bd2vd]

I want your skin, and I am going to have it. You can't stop me.

[@VeeFerns]

What about the second layer

[@WildFyr]

Here is a issue I see, what if someone made a skin in a program like MSPaint and the background was white instead of transparent, would it display the wrong player model?

[@cubicengineering4715]

I imagine the white parts would just not appear on the model anywhere. However feel free to try my skin (EngineeringCubed) as the unused are is green so it should be extra apparent if it's visible

[@lost_flower4412]

It would make if there are displayed the second layer, make the skin just a big thicc white buddy, literally

[@NotCryptid]

What about the second skin layer?

[@masterpig5s]

Okay, I don’t like the idea of programs or games sneakily reading files but imagine if read your username somehow and displayed Steve or your skin as an Easter egg on a model on a desk or something.
Could have a little boy or someone come up to you and ask what your “mc” username is etc. The default would have to be something other than Steve or Alex due to copyright. Not sure on the copyright of downloading then displaying (public) user generated content like skins. I suggest a default skin of black and purple checkerboard, as reference to the no texture texture.

[@RedStone576]

you can have rights on a skin, but you can't copyright them
