I'm not really sure what happened last month, but I didn't post anything. Oops! In the beginning of the month I was quite busy with school activities, but I started to pick up development towards the end of the month, forgetting about the blog... sorry about that guys! So... here's everything I've been working on/am still working on!
I was experiencing severe lag spikes when going from chunk to chunk. I did a bit of debugging and found that the source of the lag was saving the chunks. To optimize it, I made sure that the chunk had been modified for it to save to assure I'm not just saving the same exact thing.
After receiving help on the GMC, it was deduced that the GameMaker function ds_grid_write was slowing the game down immensely, so I tried using buffers (a faster way of saving/loading in short). It worked perfectly except for the fact that I was getting some weird bugs with it so I switched back. I will probably try to get this working again in the future.
Saving objects within chunks
I have also been working on being able to save objects within chunks. These objects are created when the chunks are initially loaded and then deleted when the chunk is unloaded. I am having trouble deleting them when the chunk is unloading, but I think I can get this working by tomorrow or the next day.
As you know, severe lag spikes happen when crossing into other chunks. I optimized it a tad by making it so that chunks had to be different than what's already saved for them to be saved again. By preloading all of the chunks, it eliminates pretty much all the lag, which is awesome.
Cellular automata caves
Today, I completed underground cave generation using cellular automata (4-5 rule)! It needs tweaking, but it's a great start. I'm excited to start adding vines, stalactites and stalagmites, and pockets of ore.
I also did some minor things:
November's monthly task is to finish the inventory rewrite (Crevis) and to begin drafting levels (Nesus).
