Hello there. Quite a moment since I talked about Alone in Space. I had hard days at work and no energy nor motivation to get back on code during nights.
But that's it! I worked tonight!
First, I made improvements on the tree rendering. I was wondering why the game was taking so much time to completely close before thinking about a memory leak. And there it was. I burnt this bug. Now everything is fine! :-)
I also corrected some placements in the tree viewport. Some nodes were rendering outside of the viewport zone.
Node now react on click. Clicking on a node center the viewport on the clicked node. Later, this will open the technology window as well. There will be a small drag animation instead of the current "teleportation".
I still have zoom issues but I'll get rid of this soon (I guess).
