[Deprecated] PaintCraft (Multiplatform coloring book & drawing app constructor)

Okay, Thanks for your reply. If I want to make this feature myself, Can you guide me on where to look for specifically?
I tried to implement it by reading the alpha value of the render texture, but it doesn't work as intended.
Thanks.

 

How to I can change Region size and position?

 

Hello.
By default bg render texture contains alpha = 1 everywhere, so you should change rendering process on swatch and everywhere.

Maybe the easiest option to compare both with alpha, but with white color?
Please take a look at how the icon generated - it uses r/w texture2d in the process and it's also downscaled so you can iterate over pixels there.

Hope this helps.

 

Sorry, could you elaborate more please, I don't understand the question. Thanks

 

I need to make fullscreen canvas and scale outline and region layers from ColoringPageConfig, but i want to save scale ratio

 

Hello, is it possible to create a paint spreading effect like this https://files.catbox.moe/1o7vtd.mp4 using this asset?

 

Hello, I am having issues with scrollviews when using Paintcraft. I'm guessing it has to do something with Paintcraft overriding the input module. Is this known or am i missing something?

Note: I'm using the new beta I got from you.

 

Hello, I've recently found out that you have published a newer 2020 version of the asset. Is it any different than the one that is included in the lunar new year bundle?

 

Hello. There is no such functionality in the project. but I'll think maybe I'll develop plugin for that

 

If this is in the gallery - not in the drawing please check that UI elements have RaycastTarget checked

 

Everyone who purchased the plugin after ~ December 6 has a free upgrade to the 2020 version. I'm sorry I was working hard to make the new release before the lunar new year so I didn't have time to make proper anoncement. I'll do that soon.

 

In 2020 version you can create pageconfig runtime. so before opening paintcraft canvas with page config you can use Graphic.Blit to scale and copy texture with required aspect.

 

hi sir , i have probleme in ios . in unity editor all is ok but when i build my game in xcode "PatternBrush region support " not working

 

I would really like to take advantage of this feature for online multiplayer but your documentation website is throwing a CNAME Cross-User Banned error. Can you make this documentation available again?

 

I got this on the Lunar New Year Bundle but can't add a new Coloring Page in the Coloring Book demo. I followed the quickstart instructions but when I go to link to the icon/outline/region png files, the box in Inspector disappears (or does not accept the file). For testing, I tried linking to pre-existing pngs (Bear files) and I got the same result so the error is not with the file. Aside from that, there are 999+ errors logged when I run the demo in Unity 2019.4.18f1

 

when i add my own images i get this error any help please? @nicloay

 

@nicloay I created my own PageConfig, created 3 images (outline, regions, icon) in StreamingAssets/PaintCraft.DemoPages folder, then write the path in the PageConfig file. I was able to color the picture in Coloring Book. However, I made some change to the regions and outline files and now I get this error when I try to open the picture to color. And the ColoringBook won't work. How do I fix it?

By the way, can I get access to the source code? It seems all the scripts are inside a .dll file

 

Any support for the Stylus pen on the Android? specifically if the pen button has been used? Not sure if it is something that is supported in Unity input or new input stuff,, or possible to support at it all?

 

everyone who is having the issue the Lunar sale posted his older version this is the 2020 version .. https://assetstore.unity.com/packag...raft-2020-drawing-coloring-book-engine-188062

 

@nicloay
Hello Nikolay! Thank you very much for this asset. There is one question: "As I understand it, the last changes are saved thanks to SaveFilePath. The question is, thanks to which method is the transition to the last change, since I would like to make indexing for each new save?" Having tried to index each time a new file is created, but it cannot return the current result in any way (although if you output through an array of bytes from the file's save directory, then it is visible)

Code (CSharp):

1.      string SaveFilePath
2.         {
3.            
4.             get
5.             {
6.              
7.                 return Path.Combine( SaveDirectory ,PageConfig.UniqueId + index + ".jpg");
8.                
9.             }
10.         }

Code (CSharp):

1.         public string IconSavePath
2.         {
3.             get
4.             {
5.                 string dir = Path.Combine( Application.persistentDataPath , "icons");
6.                 if (!Directory.Exists(dir))
7.                 {
8.                    
9.                     Directory.CreateDirectory(dir);
10.                 }
11.                
12.                 return Path.Combine(dir, UniqueId  + CanvasController.index + ".jpg");
13.             }
14.         }

 

Hi!
I just want to know can I create custom brushes using this plugin.
Like I want to create Glitter , Water Color or Pastel Color.
Can I create anything like that by changing brush material and shaders?

 

@nicloay
I want know that when and how the outline and region textures are released from memory?
I am facing memory leak problem due to these textures as I found that in memory profiler.

 

hi @nicloay , how can I draw on a raw image, I can only do it if I lower the transparency of the raw image, but it is not the best method

 

Hello @nicloay i wish you can help me add Anti-alising in TiledRegion Shader because this one makes textures over sharper and i loose the edges lines

 

Hello. Just checked again on new version 1.0.1 this bug is not reproducible

 

documentation is also available by this link but it's for previous version

 

New version doesn't have popup to select textures, as it uses StreamingAssets folder (so the final size of the build is much much smaller, like 100MB compare to 1GB as textures are stored as plain PNG)

so the configuration is looks like this (and at the bottom info box you can see where it try to find the region and outline files)

Also make sure that you use latest 2020 version of the package

 

Hm.. it looks like the texture is corrupted

Can you try to open cache folder and clear every file inside. Or does this happens on the device?

 

For research purpose you can use Rider, it allow to decompile the package. Source code inside DLL is not obfuscated. If you want me to open me some API please let me know.

 

I'm sorry but there is no such functionality in default package, you can try to open
InputController class using Rider, and see how it use brush context to apply lines and dots to the canvas, it could help you to implement your own controller.

 

Hello.
I'm sorry but in default package you can only create
PageConfig runtime and provide the path where you want to save and the version - so it's possible to save different version of the same image, (like from different sessions) but it's not possible to save different version within one session of the same image

 

Hello, yes you have access to the material, but you have to keep in mind that it's blit the result to the canvas as soon as you finished the line, so if you want to make it interactable (glitter with animation) it could be hard with this package. see this https://nicloay.gitbook.io/doc-paintcraft-in/documentation/tool-pipeline

 

Hello, sorry for the inconvenience, memory leaks are fixed in the new 1.0.1 version.

 

have you tried "draw on existing image" example? the idea is that on clear it blit (copy) the original image to the canvas, and then use standard pipeline to draw lines on top

 

Hello. could you provide example, maybe screenshot? I don't think that antialiasing is simply possible. last time when I did it for another project, I applied it to the canvas it self, not the tool. And I'm not sure that it would be easy in default package.

 

Hello @nicloay , I am having a problem with the Raw Image Saves (I have send you an email, but don't know where you check more often). In short, I don't want to save the Raw images on my device, because it uses a lot of data, how can I turn this option off?

 

Hello @Max_VRAB

As I mentioned in the email, you can manually clean PersistentFolder, there is no functionality to disable saving by default in the package.


But you can also try following ways to create your own page config

Here is a code for the fully functional page config which saves user changes and generates icon
https://gist.github.com/nicloay/3a24f8fe16a7794bb80b06b99ef9fd38

What you can try to do is to create another custom implementation for the page config,
but make sure that you do NOT implement these interfaces ISaveUserChanges, ISaveUserIcon

So just remove them from the code above (Line 7), and save that class with another name, then recreate your pages.
In this case paintcraft core should not trigger saving process

 

By the way, can I get access to the source code? It seems all the scripts are inside a .dll file

 

sorry, but there is no source code in public access.

 

Hello @nicloay, love your project! I have been using it for a while and wanted to update it to the 2020 version but ran into a problem. I want to use the DrawingGameObjectController component and needed to change the line id through code but some of the methods have changed since the previous version. Usually, I would just use your code as a template but they are all secured in the PaintCraft.core dll. I was wondering is there a way for me to edit/get the properties of the DrawingGameObjectController component through script (lineID, line config, input controller, etc)

 

Hello @nicloay, excellent work. I need to create a prefab with a gameobject that has the DrawingGameObjectController. But from the code i cant set the input controller and the paint craft camera, as they need to be referenced from the scene. Do you have any solution for this?

 

Hello @nicloay, I used you asset in my paint app. But for android 11 I am getting so many crash. For other version of Android, It works fine. Any suggestions or way to solve these crashed??

@nicloay We have the previous PaintCraft version and would like to ask a few questions before purchasing the Paint Craft 2020:
1) Are Addressables supported? If not, are there plans to support it?
2) Is there a way to load images/thumbnails from a remote server? Or at least a way to override the default "load image" behavior?
3) We are having issues with black screens on iOS, is this issue fixed on the latest plugin version?

 

Hello Ethan

Here is a code of this controller https://gist.github.com/nicloay/e179c5c612637ff9fcf5eac9062af55a you can create your own controller and adjust it with your needs including line id

Hope this helps, otherwise let me know.

 

Please create your own controller based on this https://gist.github.com/nicloay/e179c5c612637ff9fcf5eac9062af55a and then use FindObjectOfType<> to assign cameras from code. not from inspector

 

@jpchauhan I'm sorry, but from this report it's hard to say what was the problem. do you have unity logs?
Also , can you try to profile your app, just to make sure that your app is not closed because of the lack of memory (that usually happens when you have a big number of history (undo/redo) or big canvas size, like 4x4k, as all this data resides in memory)

 

As I replied to you by the mail, Addressables is not part of the package so you have to implement your own page configs and all logic by yourself based on original code from here which show that page config can be created runtime and

3d issue only appears on the metal rendering backend of the previous paintcraft version.

 

@nicloay Hello, I have bought Paint Craft 2020 with only editor.dll. How can I have source code in the engine? Thanks.

 

Hi, @nicloay I have converted the project to iOS on Unity 2019.4.17 the game works fine on editor but as I build the project the images go black can you please help.
