Does Unity have that anywhere?
Knowing how they did the following will be nice:
“paint a filled box with active brush”
“paint with active brush”
Isn’t the tile system a package that you download through the package manager? If so I believe all the source would be right there…
Maybe you can use Tilemap.SetTile
does Unity release all the source code for their engine?
I thought you get the tile system by default once you update your version to the one that has it.
I believe kurt is referring to packages, and not the core unity functionality.
In regards to the core functionality, Unity does publish the C# side of things to github:
https://github.com/Unity-Technologies/UnityCsReference
But they do not publish the internal C++ side of things.
if I can find the code for it (in the OP) it would be great. I cant seem to find any tutorials with how to do it.
You might be looking for 2D Extras GitHub - Unity-Technologies/2d-extras: Fun 2D Stuff that we'd like to share!
It contains examples with code for brushes and tiles.
There’s also the package for the same stuff.
The source for the engine, however, is proprietary and would require a very expensive source license.
