[@lemetamax]

It's more accurate with decal projectors.

[@AIAdev]

ooo i hadn't thought of that

[@lemetamax]

@@AIAdev I think it was made available in the 2021 version. Best thing about it is that it realistically projects the bullet holes on the intersection of the wall and the ground.

[@DARK_AMBIGUOUS]

I was thinking that to. What he showed in the video would look horrible if you shot a wall on an angle because the cracks would be floating off the wall

[@randomstuffwebsites]

its a lot more expensive to run, decals take more than 5 draw calls to run without even adding any decal in URP

[@briskled8955]

if you shoot close to a corner, the texture will fly in the air. Use decals instead

[@subroutinedev2322]

Good to know! I will definitely use this, if i make a shooter some day.

[@stickguy9109]

You could use quads too, they have a lower poly count thus are more optimal when dealing with tons of bullet holes at once.

[@AIAdev]

Great point!

[@JadenAllen]

I always thought quads had more triangles until I was making a water shader and realized that it has less than a normal plane, I was shocked

[@stickguy9109]

@@JadenAllen I learned it when I learned that you can look at things in wireframe mode

[@JadenAllen]

@@stickguy9109 i mean I looked in wireframe to see what the issue was but I always thought quad was for quadruple the amount of verts or something I didn't realize until a few days ago that its not

[@gentus7239]

awesome video series, pls keep it going! can you also make a video about the particle system, specifically explosions? would be awesome!

[@VJoK3R]

Nice work, you can even add another layer by using tags to create different impacts for different types of materials like metal, dirt, blood. Very useful.

[@stellar5706]

I'm currently trying to start making assets I even made a water shader for free on itch.

Srp decal : * *AM I A JOKE TO YOU???* *

[@spicyman3318]

Imagen using lwrp

[@ultmatepotato]

@@spicyman3318 you dont even know what lwrp means, im talking about the urp and hdrp when i say srp. Also imagine picking on people who use a different rendering pipeline.

[@spicyman3318]

@@ultmatepotato im not saying that lwrp is bad but lwrp generally has less support for different features and packages such as decals. I mean if your just making a simpel game it really dose not matter what render pipeline you use

[@ultmatepotato]

@@spicyman3318 it already has decals why would anyone need to install a package for that, plus in the new 2022 update you can also select what layers the decal projects on

[@ultmatepotato]

@@spicyman3318 yea so dont use urp in a simple game. I use urp for making realistic games on a lower budget. It has a bunch of good things like the vfx graph, shader graph, renderer features, cascaded shadows and a bunch more

[@youraveragedude8767]

Wouldn’t decals be better though for performance?

[@spicyman3318]

Use quad instead because it has Les polygons

[@TheGeekySandbox]

I could watch these all day. You make it look so easy! Do you think you'll do another game jam soon?

[@AIAdev]

Probably not soon. I've got a bunch of stuff I really want to work on. Game jams are awesome, but I also have the tendency to obsess over them lol

[@TheGeekySandbox]

@@AIAdev lol I can understand that. I watched a friend stream a game jam last year. I think the theme was underwater and she did a nice little game and had fun but was say she wish she could obsess less 😂 can’t wait to see what you work on next though :)

[@BestMoments707]

Nice 👍

[@xThuby]

Protip if you're doing this. Use a quad instead of a plane. And use Quaternion.FromToRotation(-Vector3.forward, hit.normal); instead. This is because planes have many many more tris compared to quads which only have two.

[@nurguy2914]

Question, how can you put the camera on top of your character (not rotating)

[@inevitable.3991]

Awesome!

[@AIAdev]

Thank you! Cheers!

[@SarThug]

I have a rough object (like up and down) how will I use a spray texture to go correctly on it

[@mcoconer7140]

thanks

[@randomstuffwebsites]

dont use plane guys, use quad, it has only 4 vertices , but the plane has 16-32 i dont remember but its a lot more expensive to run , and just change the lookup direction

[@ruumroom.]

can you do pid missiles next

[@rmt3589]

This should work with graffiti too!

[@1actose]

Can you make a tutorial on how to make non-euclidian space? It's a tough one but cool lol

[@AIAdev]

🤔

[@MrAydinminer]

So underrated

[@AIAdev]

Thank you!

[@ctct9418]

You should explain the code instead of just showing it, people don’t learn that way

[@AIAdev]

You're right. but I will say this... I used to go step-by-step through everything in my tutorials. I've been changing how I make videos based on YT retention graphs. People stop watching when things get too technical.

[@ctct9418]

@@AIAdev true true. You already sort of explain how it works in this video tho, maybe show a little snippets of the code on the side while you are explaining it that relate to what u r saying :)

[@marokidstv7207]

Thank you ❤️❤️❤️❤️❤️❤️❤️❤️

[@burakhankoroglu6030]

why nobody makes bullethole and impacts for projectile bullets? I am searching all day but nothing!

[@gameswithelectron]

Amazing

[@mossen98]

Hey wheres the best place too start learning about c#

[@tonyartz]

Maybe try object pooling to optimise this

[@aaditkrishna9380]

you could use decals too

[@AIAdev]

decals are a better option if you're using URP or HDRP and have access to them

[@shapman280]

Have you tried obj pooling solution for this?

[@akashtechdeveloper]

Wowwwwwwwww

[@o9o7_]

Hello, can you make a video on how to snap and lock the puzzle pieces in your older video?

[@AIAdev]

I answered this in the discord but figured I'd answer it here too in case anyone else has the same question... The way I did it for my puzzle game was… it’s solved in the scene. On awake the solved piece's position and rotations are saved to each piece. Then the pieces are scrambled and put into a location to grab. If the piece is dropped within a certain range of its saved position and with the correct rotation, it snaps to it.

[@janoskovacs8865]

👌

[@whatsinthemeteor]

How tô make gun system?

[@gameswithelectron]

U got a sub

[@AIAdev]

❤️

[@stonefreak5763]

WTF I mean yes, but also, use HDRP or URP and then a Decal, this does this exact thing, just also with rotation and stuff, great for blood and stuff like this too

[@noobno1551]

great content

[@AIAdev]

Thank you!

[@YuraSuper2048]

Why don’t use projector instead of plane?

[@RegenerationOfficial]

why wouldn't you draw on the texture?

[@SosaiOyama]

Holy shit someone does this

[@AIAdev]

wdym?

@@AIAdev someone who makes shorts about unity techniques

@@SosaiOyama ah lol

The KZbin "short" format is awful! I just can't use it as reference because it has no playback options :(

[@ferdzforio7715]

Hello bro can u help me with something about game

[@ZacIRL]

you should use a Quad instead of a Plane to save unnecessary geometry.

[@elctro4079]

Cool

[@AIAdev]

Hope it helps!

[@operationfrogurt]

Why a plane instead of using a quad?

[@nlk294]

Use decals.

[@CarpathianWasteGroup]

does this work on enemy mesh as well or it just spawns onto the collider itself

[@Mertovic26]

İf you shoot close to a corner 💀

[@haze42]

Can u make tutorial how to increade fps

[@AIAdev]

Use URP!

[@DARK_AMBIGUOUS]

Remove colliders from things that don’t need them

[@sidremus]

VFX artist here, this is not the way to do it. It doesn't work on uneven surfaces or when hitting the edge of a surface. Instead you should be using decal projectors. They're also significantly better in performance as they don't need a script and gameobject instance for every single bullet hole (of which you will need hundreds if not thousands of).

[@AIAdev]

video creator here, good suggestion. The problem with decal projectors are that they're exclusive to the scriptable rendering pipelines. I didn't get into it here, but the bullet holes should certainly be limited in number and pooled.

[@TegaAmrore]

Why not use a quad?

[@AIAdev]

ya, that's a better option. I wasn't thinking when I used a plane

[@WalterRDK]

Use quad, not a plane

[@parcanapp1193]

Blasphemy. Worship the omnipotence of Decals.

[@Private_Duck]

Cool but this solution is very crude and shouldn't be used on a large scale

[@koganboss4874]

Never do that. It's just awful. Even juniors don't do that, because it's not a way, it's a performance killer...

[@AIAdev]

what way(s) would be better?

[@koganboss4874]

@@AIAdev Through Drawmesh, or better yet, use a ready-made extension to draw decals. But creating gameobjects is horrible=)
