Emanuele Feronato added textures and some environment to Sokoban game prototype made with Flare3D.
I reproduced this prototype on Alternativa3D engine. And here you can find it:
Generally this port is bit different from Emanuele’s version. I can’t find information about feature like SkyBox in Alternativa3D, so this feature coded manually. Another difference is camera behavior. Emanuele binds camera to object and during rotations player object stand still and only camera fly around by its orbit. In Alternativa3d version object rotates too, this allow us to face player object it to it’s current direction. Camera is not binded to the object directly it is binded to object container and we can manipulate with player object in container, add animations, rotations etc. But both variants are good I think.
Here is source code:
