Mod Missing Signatures

Ruarc88 · June 23, 2016

Compiled my first mod for testing and Forge is crashing on startup. Crash report is incomplete (the report itself just says "... and 34 more" instead of actually including those lines). From my log file, crash seems to be happening after construction, but before pre-initialization. Erroring lines:

The tutorials I worked through failed to tell me anything about these.

As far as I can tell, there's nothing critically different from my mod and the example mod that loads and runs no problem (other than what they do).

My code (just in case)

The end goal being to disable the ability for entities to move the player.

Umm, that's a standard java thing it means that the error, and the cause of the error share the same stack at that frame. So no need to display it again because it'll be displayed in the cause stack trace.

Google jar signing. It's a method of signing the class files so that people can verify that they are from YOU and have not been modified by someone else.

There is a SHIT ton different seriously do you know basic java?

I've never seen a crash report end half-way through listing the system specs but ok then.

Thank you kindly

I thought it was obvious I was referring to the bare necessities of a MC mod when I said "Other than what they do"

Grants override access to the function applyEntityCollision (where the player actually gets pushed around by other entities)... at least that's what every override example I've seen leads me to believe. As I said, this is my first mod. If it doesn't work, I'll try something else but I need to be able to load the mod to test it.

Out of all the functionality MC has seen through mods, you're telling me there's no way to do this right now. Nevermind the fact that the functionality was part of the game for more than 5 major releases before 1.9.

That's not how subclasses and overrides work.

Not trying to be insulting but this is a obvious case where you need to go learn some of the basics of java {or any programming}

There are plenty of free resources such as MIT classes, Standord has some, and TONS of online tutorials.

Going to lock this as there isn't anything more we can do to help you besides advise that you learn a bit more.
