[1.6.4] RESOLVED Java.lang.OutOfMemoryError after registering a custom block

[DiabolusNeil]

This is starting to get really annoying. I'm working on my mod which adds custom blocks, and after launching the game for about the 100th time, every time I try and enter a world (new or old) I keep getting this error message.

The error message ends after that. I'm just trying to do a normal GameRegistery.registerBlock(), I'm using a Mac OSX 1.6.8, Eclipse SDK with Java 6 for the decompiler, and Forge 9.11.1.965. Commenting out the register method ends up in Minecraft launching just fine. If you need me to post the code, I will do so.

 

I actually did a coding timelapse a few hours before I had this issue arise. I will post it so you can see that I wasn't having this problem earlier: http://www.youtube.com/watch?v=35FQ9a_QADA

Why is your username "theboys"?

Also, is your java 32 bit?

[Jdb100]

Ok so I see multiple problems here first don't extend blockcompoundores in your block file just instead extend block and in your block compound ore don't extend anything. As your not trying to make blockcompoundore a block I assume just a subsection for all your ores. Then you don't need all the blocks you register in the blockcompoundores to be public static blockcompoundores instead do public static block and it should work.

[DiabolusNeil]

I already stated that I was doing the old method earlier, and didn't have any problems. Now when I try and do the exact same thing that I was doing hours ago, I get that error. Look at the coding timelapse, you'll see.

[Jdb100]

It worked before you had the registers because you never ended up calling that code so it just sat there doing nothing.

[DiabolusNeil]

I did call the code. It just randomly stopped working. I'll explain a bit more: I was registering blocks, same as always, it was working perfectly fine. I added two more blocks, I then started to get the error. I then commented out the lines of code where I registered the two new blocks. Same thing happens. It might be my system. I'll test later.

[larsgerrits]

Are the block IDs the same for the blocks? Are the IDs even get from the config file?

 

[GotoLink]

Most common fix for that: stop replacing the air block with a solid block. In other words; don't use id 0.

[DiabolusNeil]

I'm facedesking myself right now. I didn't have a proper ID for the Gold-Emerald ore. Now everything works. Everyone makes mistakes, I guess.
