Source code for the Tile System?

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But they do not publish the internal C++ side of things.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 https://github.com/Unity-Technologies/2d-extras

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.
