Hello,
I have been trying for a while now with no success to download the mo creatures mod for minecraft 1.6.2. I have reset my .minecraft file. I have downloaded mo creatures version 6.0.1, custom mob spawner 2.3.1, and gui api 1.56-1.6.2.jar. I am installing "minecraftforge-installer-1.6.2-9.10.0.804" to my client then selecting forge and starting minecraft. Then I drag the first three (mo creatures,custom mob, gui api) into my mods folder and I run minecraft. The Mojang text comes up then I get this Crash report:
Spoiler:

I would greatly appreciate any help.
Any slightly helpful input is appreciated.

i found out my problem you have to put gui api in mods folder not coremods

Posted 29 September 2013 - 05:01 PM

I'm having the same crash as the original poster Evanevanism  I have a theory that it is due to the load order between mo' creatures and the GUI API.  In the crash mo' creatures is trying to be constructed and GUI API is not yet constructed

MoCreatures{6.0.1} [DrZhark's Mo'Creatures Mod] (DrZharks MoCreatures Mod v6.0.1.zip) Unloaded
GuiAPI{0.15.7} [GuiAPI] (GuiAPI-0.15.7-1.6.2.jar.zip) Unloaded

And in Storm's case he gets the same exception but the GuiAPI is not listed in his mod list at all in the error dump.  Storm's was fixed by getting teh GuiAPI recognized as a mod.

I'm thinking that there is a missing dependency between mo' creatures and GuiAPI and if GuiAPI happens to load after mo' creatures then the null pointer exception of Evanevanism happens.

BTW, I think I found an error in the mcmod.info file of mo' creatures  it lists adependency with "GUI_api"  but the mcmod.info file of the GUI API lists its name as GuiAPI

But making that change and reloading didn't help, still out of order.

the issue is that GUI API is not a .jar but a .zip:

GuiAPI{0.15.7} [GuiAPI] (GuiAPI-0.15.7-1.6.2.jar.zip) Unloaded

as some browsers will change the file extension when downloading, you need to rename the file to GuiAPI-0.15.7-1.6.2.jar

Nope, that wasn't it - I've tried both the .zip in the mod folder and unzipping each of the files as well.

My error dump is showing

    Forge{9.10.0.804} [Minecraft Forge] (coremods) Unloaded->Constructed
    CustomSpawner{2.3.1} [DrZhark's CustomSpawner] (CustomMobSpawner 2.3.1.zip) Unloaded->Constructed
    MoCreatures{6.0.1} [DrZhark's Mo'Creatures Mod] (DrZharks MoCreatures Mod v6.0.1.zip) Unloaded
    GuiAPI{0.15.7} [GuiAPI] (GuiAPI-0.15.7-1.6.2.jar) Unloaded
    Launched Version: 1.6.2-Forge9.10.0.804

And then it is crashing with the same null pointer dereference
java.lang.NoClassDefFoundError: de/matthiasmann/twl/Widget

By the way, thank you very much for the quick reply.

Got it.  I was making things way too difficult.  Instead of unzipping the GuiAPI.jar.zip, all I had to do was rename it to .jar

Gday, im having the same issue.
Ive tried various versions of forge loader.
Mo creature version : 6.01 - no file extension
Custom mob spawner : 2.3.1 - no file extension
Gui api : 0.15.7  - jar file extension

Ive been experimenting with different versions of the minecraft forge and am getting similar errors as above. Im not sure how to put a spoiler in so ill hold off from putting the reports in until i see how to do that

Gday, im having the same issue. Ive tried various versions of forge loader. Mo creature version : 6.01 - no file extension Custom mob spawner : 2.3.1 - no file extension Gui api : 0.15.7 - jar file extension Ive been experimenting with different versions of the minecraft forge and am getting similar errors as above. Im not sure how to put a spoiler in so ill hold off from putting the reports in until i see how to do that

View Postgdanneels, on 30 September 2013 - 01:21 AM, said:

Got it. I was making things way too difficult. Instead of unzipping the GuiAPI.jar.zip, all I had to do was rename it to .jar

View Postgdanneels, on 29 September 2013 - 09:20 PM, said:

Nope, that wasn't it - I've tried both the .zip in the mod folder and unzipping each of the files as well.

I'm having the same crash as the original poster Evanevanism I have a theory that it is due to the load order between mo' creatures and the GUI API. In the crash mo' creatures is trying to be constructed and GUI API is not yet constructed MoCreatures{6.0.1} [DrZhark's Mo'Creatures Mod] (DrZharks MoCreatures Mod v6.0.1.zip) Unloaded GuiAPI{0.15.7} [GuiAPI] (GuiAPI-0.15.7-1.6.2.jar.zip) Unloaded And in Storm's case he gets the same exception but the GuiAPI is not listed in his mod list at all in the error dump. Storm's was fixed by getting teh GuiAPI recognized as a mod. I'm thinking that there is a missing dependency between mo' creatures and GuiAPI and if GuiAPI happens to load after mo' creatures then the null pointer exception of Evanevanism happens. BTW, I think I found an error in the mcmod.info file of mo' creatures it lists adependency with "GUI_api" but the mcmod.info file of the GUI API lists its name as GuiAPI But making that change and reloading didn't help, still out of order.

View PostDrZhark, on 29 September 2013 - 09:07 PM, said:

the issue is that GUI API is not a .jar but a .zip: GuiAPI{0.15.7} [GuiAPI] (GuiAPI-0.15.7-1.6.2.jar.zip) Unloaded as some browsers will change the file extension when downloading, you need to rename the file to GuiAPI-0.15.7-1.6.2.jar

i found out my problem you have to put gui api in mods folder not coremods

Hello, I have been trying for a while now with no success to download the mo creatures mod for minecraft 1.6.2. I have reset my .minecraft file. I have downloaded mo creatures version 6.0.1, custom mob spawner 2.3.1, and gui api 1.56-1.6.2.jar.
