z-level en cours

Extrait du Developer Diary a écrit:Z-Levels are going to be the largest enhancement to the game out of any of the kickstarter goals. In my head I see a huge amount of potential for it. The question becomes how to make it functional without crippling everyone's ongoing projects.

My first goal is going to be keeping the current functionality while changing the code to use three coordinate positions instead of just two. Getting that done will set the stage for further work without introducing massive changes all at once.

Once I get to that point I can start working on getting the world to allow seamless vertical interaction. Several things will need to be discussed at this point: primarily physics interactions, and secondarily an expansion of how natural objects are displayed over multiple levels. To expand on the second a little, small trees probably will stay one z-level in height, but fully grown trees could need to be allowed to go up to three or four z-levels in height. That will be a tricky problem that will need to be dealt with sooner rather than later. Getting gravity will work since we are working in such discrete steps. If we go with 1 z-level is equivalent to 2 meters in height, and we say gravity is set to Earth gravity of ~9.8 meters per second per second, the per tick acceleration would be somewhere close to 75-100 z-levels per tick per tick. I don't have my notes in front of me right now so I can't give the exact value I found. Gravity will probably not have that high of a value, otherwise jumping out of a window from the world's ceiling will take just a few ticks and then you are a smear on the sidewalk.

I haven't figured out what else needs to be tweaked to get z-levels working nicely, but one of the larger ones will definitely be getting the world to stream in and out of memory so you don't have such a huge amount of the world loaded at any one time. I will probably tackle map streaming first otherwise it will quickly end up as a bottleneck to progress.
