One of the best game engines for Android is now available to B4A users. Unleash your creativity!
You can read a description of this library in this guide.
Download for B4A v10.60 and older (4 MB)
Download for B4A v10.70 and newer (4 MB)
Starting from version 1.13, the library is compiled with Java 8, and thus requires a recent version of B4A and Java 8+.
To install the library, copy the .jar file and the .xml file in your libraries folder.
This library is not compatible with the Debug mode. Ensure that you always compile in Release mode.
Download also the examples and templates.
You can reduce the weight of the library if you want to keep your APK file as small as possible. Read this post to learn how to create your Lite version.
