[1.7.2] Test Run not working. (SOLVED)

Posted December 18, 201410 yr

I restarted my whole forge workspace (Typed the gradlew and all that crap) but when I began coding, I needed to test run, but only to find out

that the test run dosen't work. I have been searching for so long on how to fix it, but every method people put out dosen't work out for me.

So hopefully someone can help me here.

Console when trying to run:

It looks like you're using Java 8. I do not think that is currently supported/recommended. Mojang is still targeting Java 6 I believe.

Or, you know, just read the EAQ...

Basically: Update your Minecraft and Forge.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

I got it to work. I had JRE 8, so I uninstalled it, and got Jre7. Then I had another problem where it would say this: "no lwjgl in java.library.path" So I had to set the Native Location, then everything worked fine.

Bad pathfinding for big mobs (1.21.1)

Well I was mainly trying to figure out whether or not I was doing something wrong and if it could be fixed by just adding something (e.g. maybe I was missing an Attribute or something like that), but if that's not the case then my only option is to use custom pathfinding. If someone has one that functions and is willing to share it, then I'd gladly use that instead of suffering through making my own.

how do i change my username with forge?

In the future I do plan on adding optional OAuth to the new launcher in ForgeGradle 7. But yes, using --username and offline mode is a good workaround to not using accounts in the development environment, especially considering that the server is on LAN.

how do i change my username with forge?

I came across this post looking for an answer to the OP's question. My use case is a classroom with one server in LAN and many clients of course participants that want to test their mods.

The answer is:
On the client
Edit build.gradle. In the section client add the following line before the closing curly brace: args '--username', '<YOUR NAME>'. Replace <YOUR NAME> with your actual username. E.g. if your username is lmoellendorf the client section should look like this:

client { // Comma-separated list of namespaces to load gametests from. Empty = all namespaces. property 'forge.enabledGameTestNamespaces', mod_id args '--username', 'lmoellendorf' }
Make sure that each username is unique on your server.

Start your Minecraft Client. Click Multiplayer then Direct Conection. Here enter the Server address which is the local IP of your server followed by colon : followed by the default port 25565. E.g. if your server's IP is 192.168.0.7 the entry should look like this:

192.168.0.7:25565
On the server

Be sure that in run/server.properties the line online-mode is set to false:

online-mode=false
