C# Better block world loading, generating and saveing
I have been working on this game for a few weeks, and I have gotten flat world generation, world save and world loading working, but it is slow. Moving and loading chunks will pause the game with lag, as will saving chunks. I am wondering if anyone is capable and willing to help, maybe I am doing things the slow way? maybe this would work on a better and faster computer then mine.
This is meant to be a rpg style game, so not too much focus is going to be put on building, but I still want some save-ability and world creation. I want people to make custom maps and share them.
sorry for the mess of code
This is in my move script
public static void CheckChunks (){
Vector3 PosDis = Vector3.zero;
while (PosDis.y < 3){
while (PosDis.z < 3){
while (PosDis.x < 3){
P = PlayerChunk + PosDis;
N = PlayerChunk - PosDis;
if (N.y < 0){N.y = 0;}

you know, listing all the scrips needed for this to work makes me think maybe I should combined a few scrips.
Wowzers... I don't think anyone is going to take the time to read and figure that out. Can you do a screen grab and post a video of the result? This might help us understand what you are trying to achieve, from which we can hopefully point you in the right direction.
$$anonymous$$y computer can't run most screen capture, and the problem is fps going to 0, so yes a screen shot is what I am seeing, idk if it will help :( I am slowly starting to think it is a lack of good computer problem, also I save to a file directly under C:\, and I am stating to suspect that it may be a part of the problem, and I am trying to fix that now.
also, I A$$anonymous$$ saveing 20 5.3kb files, and I think that might also have an effect.
Your code is not documented very well so its a little difficult to pick up, Looking at your CheckChunks() function it appears that when you call this function you're checking a 7x7 grid of chunks and you attempt on checking them 200 times a second. Do you really need to check that many chunks? How big are they? Do you really need to check them that frequently? can you get away with checking a 3x3 once every... say 5 seconds?
You're also attempting to save all Chunks every 2 seconds, thus you're constantly writing to the disc when most times you don't need to. A chunk should be saved when its unloaded and when its changed (you can wait up to 10-20 seconds after the most recent change before attempting a save, long enough to reduce overhead and short enough that won't frustrate the player due to a potential crash).
I see that you are using many Try/Catches in your code. While they can work, they can be noticeably slower, especially if iterated over several times a second. It is better if you can structure your code where a try catch is never needed
I see your writing to file as a Plaintext file which for heavy data objects can slow down Saving and loading, and if its constantly creating new files that has overhead to it as well. If you're going to be loading and saving a lot of data frequently I would recommend a different approach, I would recommend looking into Scriptible Objects and the Live Tutorial. Even though the tutorial itself admits to being boring in the first half, the information it provides is pretty relevant to your performance issues as Scriptible Objects are similar to Databases in the sense that they are able to load/save volumes of data pretty quickly.
I have only seen a tiny portion of your game so I can't fathom how much work you may actually need to fix your issues, it may even be the issues your having are also due to some other code you haven't shown.
Using the Profiler is the easiest way at finding where the performance bottlenecks are.
I have failed to provide vital information in a drastic oversight, despite that you have helped me. ty
