Well, I can tell you how I hide items from NEI. Make a package in your client side package called:

codechicken.nei.api

 

Make a new class called:

API

 

Paste this in:

package codechicken.nei.api;

public class API {

    public static void hideItem(int id) {
    }
}

 

Then in both your proxy's, add this:

public void doNEICheck(int id) {}

Then in your Client proxy, add this to the body of that method(DO NOT IMPORT codechicken.nei.api!!!):

if (Minecraft.getMinecraft().thePlayer != null ) {
            Iterator modsIT = Loader.instance().getModList().iterator();
            ModContainer modc;
            while (modsIT.hasNext()) {
                modc = (ModContainer) modsIT.next();
                if ("Not Enough Items".equals(modc.getName().trim())) {
                    codechicken.nei.api.API.hideItem(id);
                    return;
                }
            }
        }

When you release, DO NOT INCLUDE the  codechicken.nei.api package. Players with NEI will already have it, and IT will do the hiding for you. Players who don't have nei will never reach the statement to error out.

 

Edit: Oh almost forgot, see how i check if the player exists? I do this because I remove the items after the player loads a world, this ensures your items are removed after nei adds them, and that idresolver hasn't changed any of your ID's in between.

Uh you do realize you have to pass the id's of the blocks you want to hide to your proxies via Mod.proxy.doNEICheck(blockOrItemIDToHide) right? My example won't work unless the world is already loaded, you can  put the call in a tick, and toggle a boolean to disable the call if it succeeds. I don't know what would happen if you try to remove an ID that doesn't exist, probably nothing, but there is no point and is a waste of resources.

    • Hello all. I'm currently grappling with the updateShape method in a custom class extending Block.  My code currently looks like this: The conditionals in CheckState are there to switch blockstate properties, which is working fine, as it functions correctly every time in getStateForPlacement.  The problem I'm running into is that when I update a state, the blocks seem to call CheckState with the position of the block which was changed updated last.  If I build a wall I can see the same change propagate across. My question thus is this: is updateShape sending its return to the neighbouring block?  Is each block not independently executing the updateShape method, thus inserting its own current position?  The first statement appears to be true, and the second false (each block is not independently executing the method). I have tried to fix this by saving the block's own position to a variable myPos at inception, and then feeding this in as CheckState(myPos) but this causes a worse outcome, where all blocks take the update of the first modified block, rather than just their neighbour.  This raises more questions than it answers, obviously: how is a different instance's variable propagating here?  I also tried changing it so that CheckState did not take a BlockPos, but had myPos built into the body - same problem. I have previously looked at neighbourUpdate and onNeighbourUpdate, but could not find a way to get this to work at all.  One post on here about updatePostPlacement and other methods has proven itself long superceded.  All other sources on the net seem to be out of date. Many thanks in advance for any help you might offer me, it's been several days now of trying to get this work and several weeks of generally trying to get round this roadblock.  - Sandermall
