Thanks to the efforts of Exodus Destiny, and after some always needed tweaking, Morgaelin has been updated to libgdx 1.9.5 from a veeery old version from around 2013.
One of the thing this allows is having a working HTML5 version, you can check the current, very early version HERE. (GIANT WARNING: DON’T BUMP INTO PEOPLE.. leaving the combat area may cause the process to hang!)
So far the experience with libgdx, at least for web, is not as straightforward as doing JS (thank you, Captain obvious). It uses GWT underneath so it’s compiling Java into JS (teh magic, after all these years still!). OTOH it generates native android programs and multiplatform Java desktop as well. May be after I sink more time into it I’ll be able to do a side by side comparison of it vs Ananias’ stack.
