[@nottheguy4328]

A mechanic that I would really love to see explored that may have a similar solution to this one is excavation from Spectrobes. It involves lazering, drilling, and air blowing bits of rock away to uncover a rotated 3D model of a fossil beneath. The fossil has health, so damaging it influences the quality of the creature revived from it.

[@Dk-Ang]

I think it would be nice if you create a small series of each of this type of videos where you explained step by step how to create it. Because they way you explained makes me think it is easy but I have never done anything like that and I am a bit lost, maybe because of my lake of experience

that was awesome!! been looking for something like that for a longo time! would be cool another for screwing bolts etc...

[@geri4367]

That's so cool. I wonder what the approach would be if you could dip the pieces into water for example. So how could we clean everything below a certain point instead of raycasting the texture

[@CodeMonkeyUnity]

Hmm calculating where the line hits would be the tricky part. Maybe with an overlap box along the water plane? And if there's a collision then do a raycast to find the UV point. Then move the test point along the water plane to find another point to get the line equation. Tricky but should be doable. After you know the equation for the line then painting under it would be relatively simple.

[@Chayat0freak]

@@CodeMonkeyUnity If you assume the water level is perpendicular to the ground you just need to know the point of collision and the object's rotation relative to the water object.

[@r1pfake521]

Hi, could you suggest some other way to implement this feature, since in my case, attempts to clear the object leads to a drop in fps from 160 to 5 frames per second

[@HaniSharif]

Quick question. What about the performance of this shader? Can this method be used on mobile platforms? Great video btw!!

[@CodeMonkeyUnity]

It depends how often you call it and how big is your brush, writing a tiny amount of pixels isn't too costly, but writing a massive amount with a huge brush gets a bit more expensive.

[@HaniSharif]

@@CodeMonkeyUnity so u r saying that my best bet is to use a small brush so that minimal pixel calculation are performed. Gotcha!! Thank u for replying and thanks for the only cleaning video on whole of youtube

[@Chuck_Greene]

This seemed really cool and wanted to investigate it more so downloaded the files. But had a bunch of errors to do with shaders etc. Im not too familiar with the different shader modes just now. Do I need to open the project file using a certain pipeline? Also do you have a video that shows how you would do something like the unscrewing part that you showed in the beginning of this video. Ive always wondered how something like that would be done, with the camera movement etc.

[@CodeMonkeyUnity]

What errors? Maybe you don't have the Universal Render Pipeline installed, maybe it's Cinemachine. Look at what the error says to figure out what is missing. For unscrewing objects, it's really just identifying what object is in front of the camera, similar to what I did in the Pick up Objects tutorial unitycodemonkey.com/video.php?v=2IhzPTS4av4 Coupled with the Crafting unitycodemonkey.com/video.php?v=_aC3NVIQ-ok Or just any interaction system unitycodemonkey.com/video.php?v=LdoImzaY6M4

[@Chuck_Greene]

​@@CodeMonkeyUnity Turns out most of the issues were because I didnt have URP installed. I still got some issues to do with LWRP but once i reverted back to an older version of the editor all errors went away. Thanks for the previous response. I did also have to set the render pipeline in the projects settings, (in case anyone else is new to the shader stuff and is struggling :) )

[@VaupellGaming]

Excellent, now do one in 3D space, like the "power wash" simulator. . :D Cleaning a 3d game object in 3d space.. I would exspect it to work similar, but with raycast from camera to gameobject instead to find "where" plr is cleaning. (possible, also the angle)

[@CodeMonkeyUnity]

Yup the object in this demo is 3D so it's really the same thing, the only difference is you're moving the camera around and using the camera center position as the raycast origin and the camera transform forward as the direction, just like I did in my third person shooter kzbin.info/www/bejne/fJOwZXahptmCq6M

[@MarceloL_R]

It's very nice when a professional makes this kind of analises. Thanks a lot. An doubt, if instead use this technique how about use the render pipeline (URP or HDRP) to choose what is shown? Like we paint the surface with invisible color and the render pipeline doesn't show the dirt layer (like how they make the character visible when behind other gameobjects in Unity open project). It's possible? Which one has less computational weight?

[@MarceloL_R]

Thanks!

[@CodeMonkeyUnity]

That would be a very weird way to do it, you would need to play around with multiple layers, maybe some custom shaders to write some stencil data. It would technically be possible but needlessly complex.

[@MarceloL_R]

1:47 This had better be available for Linux. Because if it isn't, why would they use a Tux penguin from old Linux logo's?

[@GDarrenGould]

I am having some trouble implementing this in 2D. Using Physics2D obviously and the only other difference is that the textureCoord is equal to hit.point rather than hit.textureCoord. Apart from that I haven't changed much, but can't seem to get it to work. The raycasts are working properly, but the texture is not being updated. Any suggestions or ideas on what the main issue may be?

[@CodeMonkeyUnity]

Hmm I haven't tried this specific method in 2D, you could still use the same method on a Mesh Quad. When using a SpriteRenderer I'm not sure how it would change, you might need a diferent method converting the mouse world position into a sprite local position and calculate the UV, not sure

[@GDarrenGould]

@@CodeMonkeyUnity You pointed me in the right direction and I figured it out, thank you! For anyone wondering, the key is to use the physics2D GetRayIntersection, and then do a transform.InverseTransformPoint on the raycastHit.point, and multiply that by the sprites pixels per unit to keep it consistent across different scales. Then you've just got to offset that to account for the fact that the sprites (0,0) is in the center, rather than in the bottom left as it is on the Texture2D, and then everything else is the same!

[@GDarrenGould]

Vector2 textureCoord = transform.InverseTransformPoint(hit.point) * pixelsPerUnit; textureCoord.x += spriteRenderer.sprite.rect.width / 2; textureCoord.y += spriteRenderer.sprite.rect.height / 2;

[@zildeos9858]

Solid video as always but i actually came in thinking this is all just shaders cause i imagine getting a single pixel every frame using the cpu would be kinda costly

[@CodeMonkeyUnity]

As always it depends on the size of the brush and your target device. For a Desktop PC this approach works perfectly fine, if you're targeting low end mobile devices then maybe you need some extra optimization.

[@lemangkuk]

Hello have a question here, so I've follow the tutorial, and manage to do it, but have a question here, how do I change from a mousePosition and raycast to detect if I'm hitting the object that need to clean to a 3D object that can clean, for example you are holding a wipe cloth in VR, and you move the cloth and it will clean the object.

You can implement a texture and dynamically modify that texture, like I did here unitycodemonkey.com/video.php?v=Xss4__kgYiY

@@CodeMonkeyUnity Hello again, Okay. I manage to change from using mouse to using a line raycast to detect if I'm hitting object so I can spray on object. but now I have a bit off an issues.

I don't understand the part about cleaning the object... Is the GetPixels and SetPixels method different from the shader graph method?

Not sure what you mean, SetPixels is being used to "paint" the mask texture which the shader then uses to show/hide the dirt.

[@lemetamax]

@@CodeMonkeyUnity I understand that part, thanks. But...what's the need for GetPixels

[@CodeMonkeyUnity]

It uses GetPixels to read the brush mask so you can use a brush that is not just a solid square

[@blackorzarblack1655]

@@CodeMonkeyUnity yes, the problem is in the UV positions, but I don't know how to fix it. I try everything I can think of but nothing works :D

So It's a weird Questions. But what are the chances that you can make a Video on how to create a Grid System without using you Utilities?

The utilities have all their source code included, there's nothing stopping you from taking the functions in those classes and pasting them directly in the Grid class. But that will just add needless bloat to your Grid class, your code should be cleanly separated.

[@qiangqiangpan2362]

Wow, Your tutorial is really rich. Could you explain how to make a replay system for the game? I need to make a simple game replay system for a combat system. Any ideas?

[@CodeMonkeyUnity]

The simplest approach is to just store all the inputs every frame then play them back exactly the same. So you store "frame: 126; isPunchButtonDown: yes; playerPosition: 10, 2, 5" That's the simplest approach but will lead to massive save files. The better but more complex approach would be to only save data when something changed like when a button is pressed. You could try to get a prototype up and running with that method, just save that data like any other data kzbin.info/www/bejne/bKawd3iDYtOUpqc

Playing with wrap mode but couldnt achieve to prevent this happening. Hope you have a solution for this, thanks

[@CodeMonkeyUnity]

Sounds like the asset was made to reuse parts of the texture, you would need to remap the UV to make sure all the parts are unique. I'm not an expert 3D modeller so not entirely sure how that process is done, I'm sure Blender can do it but not sure how.
