XUI2D and iXUI2D share the same API and together with BitmapCreator, XUI library and the X2 library they allow to build cross platform games.

Installation instructions:

- XUI2D - latest version is preinstalled.
- X2 - v1.22

Start here: [XUI2D] Example Pack

V1.22 -You can add X2SkipLogs as a conditional symbol (Ctrl + B) to remove the most frequent log messages.

XUI2D v0.92 and X2 framework v0.92 released.

- New class templates:



- Support for world contact callbacks. This is a more robust way to handle collisions. For example in this screenshot you can see a one way horizontal body. The collision is only enabled if the kid is above the block.



- Ray casting. Cast a ray and find the bodies that are intercepted by the ray. You can see its usage in the walking character example. Touch or click on the screen to fire a laser beam.

- Many small improvements and bug fixes.

Note that the Game class template has been updated. I will update all the current examples.

New versions released. Large update with many internal improvements. X2 framework now includes a class named X2TileMap that makes it easy to create tiled maps and objects with Tiled map editor: https://www.mapeditor.org/

Large update including BitmapCreator v4.17 and XUI2D v0.95. The X2 framework was also updated with many changes.

New examples pack with all the currently available examples: https://www.b4x.com/android/forum/threads/xui2d-example-pack.96454/#post-608505

There was an important breakthrough in the B4A implementation and the performance was significantly improved.
All the examples now run in 60 fps on a 5 years old (and quite weak) Nexus 5 device.

BitmapCreator v4.20 released. It includes a new method for drawing rotated anti-aliased bitmaps. It is significantly faster in B4J and B4i (up to 10 times faster). It is not used in B4A for now as the performance is similar to the canvas based performance.
It is managed internally in X2SpriteGraphicCache.
