X2 is an open source, cross platform 2d game engine based on box2d physics engine and BitmapCreator as the rendering engine.
X2 itself is a b4xlib library.

The first versions of X2 lead the way to cross platform B4X projects. The new update goes the other way, and makes X2 work with B4XPages. This simplifies several things.
There is also a new class named X2Multitouch which provides a cross platform method to handle touches, multitouches and keys (B4J).

X2 works best with Tiled map editor: https://www.mapeditor.org/
When you first start with Tiled, you need to import the x2 custom properties. This is done with:
View - Objects Types Editor - File - Import and find objecttypes.json: X2\X2 Source Folder\Shared Files\objecttypes.json

If you are not seeing the custom properties when selecting an object then it is misconfigured:

X2 source code and examples are available on github:
Download link: https://github.com/AnywhereSoftware/X2/archive/refs/heads/main.zip
X2.b4xlib: https://github.com/AnywhereSoftware/X2/raw/main/X2 Source Folder/X2.b4xlib

The first effort was to update the almost 20 examples to the new version.
Some of the examples are a bit complex and are more of a "proof of concept" projects.

Recommendations:
1. Start with B4J
2. Start with these examples and more or less in this order (the examples threads were not yet updated):

Tips
- The files from the Shared Files folder are copied to the platform specific folder during compilation. Don't update the files in the Files folder as they will be overwritten (except of files unique to the current platform).

Updated X2 Game.b4xtemplate is attached. It includes the manifest line from post #10.

That's awesome erel. i believe that xui2d has a lot of potentials it just needs some published games in the store to prove it is a good framework and this will make it more interesting for people. i am planning to make one in the near future.

After updating; I got this error when opening B4J Space Shooter example:
Unknown type: b4xmainpage
Are you missing a library reference?
and the compiler error:
Error description: Unknown type: b4xmainpage
Are you missing a library reference?
Error occurred on line: 73 (B4XPages)
Public Sub MainPage As B4XMainPage
What I missed?
