Hello! I just joined the forums. Nice to meet you all. c:

 

I have just gotten started on this project, and as I'm fairly new to Minecraft modding am running into quite a few kinks. One of the suggestions were to override the entity renderer hashmap with the model that I wanted to use.

 

However, I am getting this crash log, and I... don't even know where to begin with it, to be honest.

Thank you for your time and help!

Wow, I'm pretty surprised at how simple a change that was! How did you find that bug, if you don't mind me asking? Was it just by looking through the Model base that I made? Because I can't seem to find it in the crash log at all.

That bug has been in Techne a long time now, so we know where to look if there's a NPE in the model class.

I see! Gotcha.

 

Also I don't want to spam up the forums, so can I get help on something unrelated? For some reason, my mcmod.info file refuses to work.

 

I have a screenshot of the file and my mod setup here.

 

Also made the silly mistake of putting my constants as string literals rather than fields of a class, but upon taking out the parentheses, my main class is unable to find the Constants class.

 

Here is how the file shows up on the console (before I took out the parentheses):

 

And here is my (very short) Constants class from my lib folder:

 

package ruirui.minecraft.livelyanimals.lib;

 

public class Constants {

public static final String MODID = "livelyanimals";

public static final String MODNAME = "Lively Animals";

public static final String VERSION = "0.1";

}

 

 

Well, your mod setup is kinda weird. You have

java

and

resources

source folders, but they need to be

src/main/java

and

src/main/resources

. Maybe that's what's wrong.

Do you have a @Mod tag in your main mod file?

I have a similar working setup as following:

@Mod(modid = Constants.MODID, name = Constants.NAME, version = Constants.VERSION)

 

Also, is your mod in a different java project? Because I see that you got a Minecraft project AND a "LivelyAnimals" project that your files are located in.

 

Try moving the java files into the Minecraft project under "src/main/java" and the mcmod.info to "src/main/resources" (As noted by Iarsgerrits)

Moved the files as suggested, but it still does not work unfortunately.

 

Oh Eclipse, you are a piece of work. I took out my files and then did refresh-dependencies to see if I could fix it that way, and now the only thing that shows up in the workspace is HerdCraft and when I go to add existing projects into the workspace, it says "No projects are found to import".

Okay, whatever. mcmod.info is pretty much the least important part of the mod anyway.

 

New problem: Can't seem to find my texture.

I've also tried "assets/textures/animals/LAPig.png" and "ruirui/assets/textures/animals/LAPig.png". LivelyAnimals.AID is just "livelyanimals".

Sorry, but I'm still not sure what to put. I tried to put the full path name and it failed.
