Changing the material using declared fields of a block

Hey there!

I need help again
Because I'm updating BlocksOnGlass a bit, I need to "fix" the blocks.

Code:java

        Block.byId[Block.ICE.id] = null;
        Block.byId[Block.ICE.id] = new bogBlockIce(Block.ICE.id, 67).setHardness(0.5F).a("ice");
        try {
            Field field = Material.ICE.getClass().getDeclaredField("G");
            field.setAccessible(true);
            field.setBoolean(Material.ICE, true);
        } catch (Exception e) {
            e.printStackTrace();
        }
        Block.q[Block.ICE.id] = 3;

            world.setBlockWithNotify(i, j, k, Block.waterStill.blockID);
        }
    }
 
    public int getMobilityFlag()
    {
        return 0;
    }
 
    protected ItemStack func_41001_e(int i)
    {
        return null;
    }
}

Can anyone explain me a bit more, what field I'm going to change?
I don't know where I can find the different fields...
And what's the difference between

Block.q and Block.t ?

=> Goal is to change the rules to place things

Thanks!

 

I'm not understanding your goal here. Bukkit lets you change a block directly, no need to work with the net.minecraft obfuscated fields at all. block.setType(Material.DIRT);

 

Yeah. But can I do this before a event?
I have to change the blocks at the onEnable() part. Otherwise the items will drop (eventually) off.

 

I'm not really sure what you're trying to do. The "G" variable seems to be "isReplaceable" and there is no "F" variable.

 

Yeah that's my problem. I don't know what which variable is exactly. I searched for hours in all the damn files.

 

Well what are you trying to accomplish?

 

@nisovin

To change the material of the block to Dirt or Stone => Would be possible to place doors, rails, redstone, etc.

 

You're not trying to change the material, then. You're trying to change the adjacency rules of glass, so that other stuff is allowed to attach to it.

 

@halley

Not true and not false.
For some block I can change the material

Code:java

        Block.byId[Block.GLOWSTONE.id] = null;
        Block.byId[Block.GLOWSTONE.id] = new bogBlockGlowstone(Block.GLOWSTONE.id, 89, Material.EARTH).setHardness(0.3F).a("glowstone");

For some block I need to change the "rules", that's true.
Because it's not my plugin and I'm only updating it, I don't know the code sooooo well.

 

no one?
anyway, a little bump

@halley

Tried your suggestion, but it changes the block to dirt/stone/whatever

I updated the OP to be more specific (change the rules like you said)

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Try setting H to false.

If that doesn't work, just try random ones until you get it. Sometimes that's all you can do.

 

@nisovin

WORKS! Wow. Why "H"?
Can ya tell me why you told me to set H to false?

But anyway:

Difference between Block.q and Block.t?
