Amazing <shakes head>. Whenever Minecraft selects an element from a weighted list (such as the creatures that can spawn in a biome), it adds up the total weight of elements in the collection. Again and again and again.

 

Shouldn't the weight only change when an element is added or removed? If so, then shouldn't total weight be pre-calculated at the moment a random selection is made?

 

More importantly... Am I missing something here? Is total weight sometimes more dynamic than the building of a list at load time?

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

It doesn't matter. The lists are small so it's fast enough. We're not in the business of re-writing stupid things like this. So Why does this matter and what do you expect us to do about it? You can find a lot of issues and inefficiencies in MC code base, welcome to Minecraft....

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Oh heavens no, I don't expect Forge to correct minor MC inefficiencies. I was just worried that there was something hidden that I needed to understand before deciding what weight to assign to my new animal(s).

 

Thanks for confirming that my myopic impression was close to the mark.

      MC Server Crashing MC Eternal *Reward for Fixing*

      By redryder · Posted

      Hello All! Started a MC Eternal 1.6.2.2 server on Shockbyte hosting. The only other mod I added was betterfarmland v0.0.8BETA. Server is 16GB and Shockbyte wont tell me how many CPU cores i have.  We are having problems now when players log in it seems to crash the server. At other times it seems fine and we can have 3 people playing for hours at a time. Usually always when it does crash it is when someone logs in. Crash Reports Below. To the person who can post the fix I will reward $100 via Paypal.   ---- Minecraft Crash Report ---- // This is a token for 1 free hug.
