Hi,

 

I've created a basic mob spawner TileEntity, but I'm having a problem where the worldObj is sometimes always remote. It works fine when the block is placed, but not when it generates in the provideChunk() method in my ChunkProvider. Here's my code:

public class TileEntityStupidSpawner extends TileEntity {

private String entityName;
private int spawnTimer;
private Random rand = new Random();

@Override
    public void readFromNBT(NBTTagCompound tag) {
        super.readFromNBT(tag);
        this.entityName = tag.getString("EntityName");
    }

@Override
    public void writeToNBT(NBTTagCompound tag) {
        super.writeToNBT(tag);
        tag.setString("EntityName", this.entityName);
    }

@Override
    public void updateEntity() {
        super.updateEntity();
        for(int n = 0; n < 3; n++) {
        	DivineRPG.proxy.spawnParticle(this.worldObj, this.xCoord+0.5, this.yCoord+0.5, this.zCoord+0.5, "blackFlame", true, 3);
        }
        if(!this.worldObj.isRemote && this.worldObj.getClosestPlayer(this.xCoord+0.5D, this.yCoord+0.5D, this.zCoord+0.5D, 16D) != null) {
        	if(this.spawnTimer > 0) this.spawnTimer--;
        	if(this.spawnTimer == 0) {
        		int c = this.worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(this.xCoord, this.yCoord, this.zCoord, this.xCoord+1, this.yCoord+1, this.zCoord+1).expand(8, 6, ).size();
        		if (c <  {
        			for(int i = 0; i < 4; i++) {
                		Entity e = EntityList.createEntityByName(this.entityName, this.worldObj);
        				if (e != null) {
        					int x = this.xCoord + this.rand.nextInt(9) - 4;
            				int y = this.yCoord + this.rand.nextInt(3) - 1;
            				int z = this.zCoord + this.rand.nextInt(9) - 4;
                			AxisAlignedBB boundingBox = AxisAlignedBB.getBoundingBox(x+e.boundingBox.minX, y+e.boundingBox.minY, z+e.boundingBox.minZ, x+e.boundingBox.maxX, y+e.boundingBox.maxY, z+e.boundingBox.maxZ);
            				if (this.worldObj.checkNoEntityCollision(boundingBox) && this.worldObj.getCollidingBoundingBoxes(e, boundingBox).isEmpty() && !this.worldObj.isAnyLiquid(boundingBox)) {
            					e.setLocationAndAngles(x, y, z, this.rand.nextInt(360), 0);
            					this.worldObj.spawnEntityInWorld(e);
            				}
        				}
        			}
        		}
        		this.spawnTimer = 400;
        	}
        }
    }
    
    public void setEntityName(String name) {
    	this.entityName = name;
    }
}

 

Putting print statements in updateEntity shows that sometimes it works as expected, with the worldObj being remote half the time and not the other half, but sometimes it is constantly remote. Even when it isn't, mobs are never spawned. If I make it spawn mobs on the client, they appear normally (but don't move of course).

So it works when it is placed by other means, but it only doesn't work if used in provideChunk within your own ChunkProvider?

 

Can we see your ChunkProvider then?

Here's the ChunkProvider: http://pastebin.com/6wahCzv3

 

The ArcanaChunk class just has methods to set blocks. Here it is:

public class ArcanaChunk {

private Block[] data;
private byte[] meta;

public ArcanaChunk() {
	data = new Block[32768];
	meta = new byte[32768];
}

public void setBlock(int x, int y, int z, Block b) {
	this.setBlock(x, y, z, b, 0);
}

public void setBlock(int x, int y, int z, Block b, int m) {
	data[x<<11 | z<<7 | y] = b;
	meta[x<<11 | z<<7 | y] = (byte)m;
}

public Block getBlock(int x, int y, int z) {
	return data[x<<11 | z<<7 | y];
}

public Block[] getChunkData() {
	return data;
}

public byte[] getChunkMetadata() {
	return meta;
}

}

How did you place your StupidSpawner? Please show the code related with placing the block.

It seems that there would be the problem.
