Minecraft Forums

Following tutorials on youtube, I tried my best to install the Mo' Creatures mod for 1.7.2. However, it keeps crashing... so something's gone wrong along the way.

Here's some things I did during installation-
I used the forge file (and previously changed my own profile to 1.7.2 instead of 1.7.4)

When following tutorials, I noticed that my files were zipped folders whereas the youtuber's files were like books stacked on top of each other... if this makes sense lol.

Where have I gone wrong?

Crash report I got when I started up minecraft-

// Quite honestly, I wouldn't worry myself about that.

Sorry to hear you're having trouble. Installing mods can be very frustrating, especially when they don't work!

I would recommend installing this mod with MC ModKit! Anyone can use MC ModKit with zero modding knowledge! There is no "setup". You simply launch MC ModKit, discover the mods you are interested in and install them! MC ModKit automatically takes care of everything for you!

The most difficult decision you'll have to make is "What mod to I want to play?"

You can learn more about it here: http://www.minecraftforum.net/topic/2398032-mc-modkit-update

I've PM'ed you a beta code so you can download it and see for yourself.

Quote from LeProDude

Install mo creatures using the skydaz installer - http://www.skydaz.co...inecraft-1-7-2/ scroll to the buttom of the page and the downloads are there. it installs the mod for you.

also theres no version of custom spawners for minecraft 1.7.4. only 1.6.2
http://www.minecraft...om-mob-spawner/

hope i help

oh so thats what is probably wrong... the mobspawner.
So i'll have to wait till a 1.7 comes out?

Actually, there is a mobspawner for 1.7.2. It's just not on the CustomMobSpawner thread. It is, however, available from the Mo Creatures thread here:

http://www.minecraftforum.net/topic/81771-172-mo-creatures-v620-with-ents-and-moles/

Look under the section titled Latest developers' version is available here

It has downloads for CustomMobSpawner that works with 1.7.2.

I used the skydaz installer... and it worked fine.
Thankyou for all your help:)
