Minecraft Forums

Hello, so I’ve got a macbook pro and I’ve installed minecraft mods. So far the mods I’ve downloaded are; Helpful villagers, Survival wings, Biomes O plenty, CraftGuide, Mo Creatures, fairy lights, Lucky blocks, MrCrayfish’s Furniture mod and Pam’s Harvest mod.

The main two I want is Mo Creatures and Helpful villagers. But every time I open it crashes before you get to the ‘Play Multiplayer Realms Mods’ page. I’ve downloaded Forge and Forge Modloader but it won’t stop crashing. I can load it on another profile without mods on.

Crash report (That’s with only forge and helpful villagers in the mods folder)

Ah! That will be it. I thought I had got the 1.7.2 version. *Crosses fingers*

Just get a Windows PC, more gaming friendly

//Yes but I had to have this for school and it works fine (untill you get mods...) also another computer costs money.\\

But it's now not crashing but I get this message:

"Forge mod loader has found a problem with your minecraft installation

The mods and versions listed below could not be found

SC0_SpaceCore : any

The file 'logs/fml-client-latest.log' contains more information"

I'm running forge on 1.7.10 and I have lucky blocks, survival wings, Mo Creatures, Helpful villagers, Mr Crayfish's furniture mod and Pam's harvest mod. They're all for 1.7.10.

That's why I hate mods that need a seperate core/library. I'd only take the time and effort install a core/library if I were to download all the authors' mods at once instead of wasting a minute of my life finding out why a mod won't load without a core.

TL;DR Don't use a seperate core/library for any of your mods

What if you want other modders to be able to use that library without downloading a whole one of your mods? And you wouldn't have to figure out what mod needs a library if you read mod instructions.

Why would I want to install a mod core if I do not intend to use the author's mod/s?

Libraries/cores dont always come with mods. Mods can be made off of a library, for example LLibrary, I'm pretty sure, has no mod associated with it. It was designed to be a lightweight mod library FOR mods to be developed with. But for the bulk of the cores out there, you have a valid point. Just include the library in your mod, and distribute it as a package for other modders. The whole thing with cores makes it a little harder for new players to get into modding, as if it isnt already complicated enough for such a "simple" game.
