I'm currently trying to make a mod that uses ComputerCraft as dependency, and I followed a thread on the computercraft forums on how to set that up ( have a deobfuscated jar, referenced in the project, and located at mcp/libs )

 

The mod is currently just a main mod file, a block file which gets a custom creative tab and texture, and a client/commonproxy, and the main mod file registers the blocks and creates the creative tab.

 

This is what happens with what I tried:

 

• When running minecraft from Eclipse with the 'run' function, and my mod disabled ( commenting out @mod and @networkmod ) minecraft launches fine and I can walk around in my world
  
• When running minecraft again from eclipse / 'run', with my mod enabled, minecraft launches, and the Gui works, but when trying to open my world, it crashes with this error:

I can't really figure out what the problem is, as in the errors my mod isn't mentioned anywhere ( it's called net.nbtforcc.MainMod, and so on )

I'm getting the feeling I've caused some sort of loop that doesn't stop, and overfloods an Array ( because that is being mentioned in the errors ) because the first time I tried, I didn't close my minecraft for a long time, and after a while I had 10Gb of used memory ( seen from taskmanager ).

 

If anyone has an idea of what could be going on you could really help me out.

well you knwo exactly whats going on.

 

java.lang.OutOfMemoryError: Java heap space

thats basicly the JVM saying

 

WOOOO MAN TOO MUCH SHIT HAPPENING

 

are you creating like 100 000 000 000 000 object? somewhere ?

because all that says is that you are using too much memory

Well you're able to see the source so...

welll yknow i can help but you have to do some of the work too

 

you're instancing your dataBlock staticly, try doing that in the preinit it *might* be part of the problem

it appears that this loop is stuck forever ( EntityPlayerMP line 178 )

 

        while (!par2World.getCollidingBoundingBoxes(this, this.boundingBox).isEmpty())
        {
            this.setPosition(this.posX, this.posY + 1.0D, this.posZ);
        }

 

so as far as I'm understanding, for some reason my mod is causing everything in the world to be occupied with something, which causes this loop to keep checking up where there might be space, but there won't be...

are you filling every possible block ?

not as far as I can see... I'm adding a new block to the game... that's basically it... I'm now trying to switch to a different version of forge

did you instanciate your block in your preinit ? like i said ?

yup, I found out I was using the latest version of forge, instead of the latest recommended for 1.5.2, so i tried that, same result.. I also tried 1.6.2 ( with other computercraft lib ofc ) same result

well that was stupid, I accidentaly set the block ID integer after using it to set the block ID, so the block ID was set to 0, which is air, and so all normal air blocks were now my block...
