Minecraft Forums

Problem solved! I don't know how this happened but I had the wrong GUI version in my mods folder. *facepalm* That's odd since I grabbed everything at the same time and the other two files were the correct versions.

I still can't dowload it. Any help?

Quote from RViper28

That was a bug in MCPC+. It was fixed in B56 of MCPC+.

RViper, thanks for the response. Just one thing, I AM running B56 :/ At least I'm fairly sure I am! But just in case I'll redownload B56 and see if that does anything

got a crash
maybe you can help me:

Quote from meltdown44

How do you breed the vannilla horses, and mocreatures horses? id like to have a pegasis in 1.6

Everything is the same except Vanilla horses take golden apples or carrots to breed while mo horses take pumpkins

Is this compatible with Biomes o Plenty mod?

Quote from dave11

What does your MoCStructures.cfg say? Unless they changed something I believe that's responsible for spawns in nether fortresses.

Mine says:
(I seem to recall that this may have been empty after installing one of the recent versions so I could have copied this over from an older one...?)


And proof that I have wither skeletons in my fortresses: (may have turned down spawn rates of other nether mobs too)

(edit: this is in singleplayer and if you are on a server there may be some differences of course)

Interesting. MoCStructures.cfg has always been blank for me. I have conflicting statements from Bloodshot whether it is/was even supported (here it is/was and here it isn't).

Hello all, first off im new to all this stuff, im trying to getting MO'S to work for my daughter.
I have downloaded all the files and followed all the steps but mincraft crashes everytime. im using 1.6.2.
can someone please help?

both of you are suffering from the same problem, your browser tagged an extra .zip on the end of GUIAPI. Remove it.

Quote from DensonJ

I'm having lots of fun trying to get the latest version of Mo Creatures to work on my system. I'm using only the GUIAPI, Custom Spawner and Mo Creatures for testing with Forge build 804. I even completely re-installed Minecraft to be sure, but it's still failing. This happens on both my Windows and Mac machines but the log is from the Windows box. For the record, a lot of other mods I use are working just fine in other testing (SPC, Animated Player, ARMinecraft, dragonmount, Legendary Beasts, Galacticraft, Hoonpad, mapwriter, MCA, MicdoodleCore, Slender Man, etc...). But for the current Mo Creatures testing I'm keeping it very basic. Below is the crash log.

you didn't install GUIAPI in your mods folder like you should. 1.6.2 did away with the coremods folder

Quote from 10Pumpkin

Is there any way to add this to a 1.6.2 server?

yeah, dump the CMS and MOC into the server's mods folder. GUIAPI is clientside only. Do not install server side.

I got this error when i tried riding a wyvern:

Quote from Kye_Duo

both of you are suffering from the same problem, your browser tagged an extra .zip on the end of GUIAPI. Remove it.

i tried and no change same error everytime

playing around a little i found that having the spawner and GUIAP in the mods folder load and game works perfect. but the everytime i put the mo's creature mod in try it crashes everytime.

Crash report! I have other mods, but deleted them all so this would run, but it didn't work.

both of you are suffering from the same problem, your browser tagged an extra .zip on the end of GUIAPI. Remove it.


you didn't install GUIAPI in your mods folder like you should. 1.6.2 did away with the coremods folder


yeah, dump the CMS and MOC into the server's mods folder. GUIAPI is clientside only. Do not install server side.

Ok folks, I'm going to post this here because it's probably happening to others.

The crashes above involving the "java.lang.NoClassDefFoundError: de/matthiasmann/twl/Widget" issue can be tracked two other potential causes, particularly for someone installing 1.6.2 for the first time.

1) The GuiAPI-0.15.7-1.6.2.jar file, for whatever reason, seems to be an incomplete download for a small percentage of the time. Make sure the file is 1.7MB in size, it ends with a ".jar" not a ".zip," and it sits in the mods folder.

2) For sure for mac users, though it's probably not specifically on the mac, the latest Forge installer is having trouble downloading the scala libraries in a complete form. When it crashes out, and you run the installer a second time, it finds incomplete files and presumes they are loaded. Forge then fails to load them properly, which leads to other problems I'm guessing. I was able to download the incomplete files (namely the scala-compiler-2.10.2.jar and scala-library-2.10.2.jar) manually and it seemed to stop giving me warnings.

Once I corrected these issues I got 1.6.2 Mo'Creatures to load properly without crashing.

Ive been feeding both my unicorn and my pegasus essences of light and they wont breed- ive been waiting for several in game days. Anyone know how to fix this?

Breeding in this mod is just impossible... it takes too long for what you get in return, the combinations are buggy and wierd, if you even get the chance to find the right horses.
