I (and others, I'm sure) want a harder experience in Minecraft. I think that increasing the spawn rate of mobs is a very simple solution and it has a simple execution http://www.minecraftwiki.net/wiki/Spawning
After reading through that I have two solutions to make mobs spawn more often
1. Increase the cap of mobs. Change the cap from 70 to 250 or something like that. Obviously you can't make it unlimited because then the amount of mobs in a chunk will get too high and it could cause lag or crashes.
2. Increase the amount of attempts to spawn mobs. In the fourth paragraph after the article finishes discussing caps it states "If the pack location is suitable, 12 attempts are made to spawn up to 4 mobs (8 for Wolves, 1 for Ghasts) within a 41x1x41 area centered at that block (that's a 41x41 square that is one block high)." If the number of attempts was increased to something like 50 it would increase the chances of a successful mob spawn. Again, you can't increase it too much without making the game lag or crash
3. If a monster does not attack or make an attempt to attack within 1 minute 30 seconds of spawning, it despawns.
This would help the whole "limit" of mobs being taken up by monsters that are in caves that you're never going to find.
I have an endermen grinder on the server I play on. The efficiency isn't what I expected it to be like and I believe it's because of slow spawn rates. Would raising the cap and all that stuff that you mentioned help me?
Hoping this thread didn't go Necro...
Also, that green text is hurting my eyes
Anyway, If you use Bukkit, you can easily change the mob cap by changing a parameter in the bukkit.yml
Bukkit is a free, and very popular server platform for minecraft, and many modded varieties. While I recommend this alot, Minecraft does need something like this to make things more interesting, plus the ability of having this within singleplayer worlds.
The vanilla setting for the mobcap is somewhere around 60, and quite frankly, that's a bit low. about 3/4 of the mobs are going to be spawned underground, and only about 15 are going to be on the surface. Now, that's not bad for a first or second night, but I feel as if the mob cap should get raised every night. However, this can easily get out of hand, so there need to be safeguards to make sure that it doesn't exceed ridiculous amounts.
So, I figure that if you're going to add in some sort of mechanic that does this, you might want to give the player some sort of control over the spawn rates, preferably through the use of something insignificant, like say, Mob drops!
And also, it doesn't have to be that big of a mod, just something to add in. And why not use pre-existing blocks? I feel as if the cauldron is extremely underused, and this would be a really interesting use of it.
Vanilla mobcap: 60
New proposed Mobcap rules:
Starts at 64
raises by 8 every night
Mob drops dumped into a cauldron would decrease/increase the mobcap (changes take effect every morning, for performance/handling purposes)
Different mobdrops equal different amounts
I play with my setting up to 256 mobs, and that stays pretty interesting. It was actually kinda lonely when I played vanilla, because there was nothing around. Someone needs to make a challenge for the more hardened veterans in the minecraft community
