Hey,

I was wondering if there is a way to force a light update on a certain block. I've tried forced block updates, forced render updates, changing the metadata of the block and even calling world.updateAllLightTypes without success.

This is my code right now http://pste.me/IvXo8

Btw it does update the lighting when the block is activated a second time.

Hi

 

curious that world.updateAllLightTypes(x,y,z) didn't work.

 

Did you try tracing in to see why not?

I've changed the code a bit. http://pste.me/1LCqv/

According to the console output the light level on the server is correct, however the client always has value 15. It even prints out 15 when the client world is dark at that position.

2013-12-23 20:23:20 [information] [sTDOUT] Client: 15
2013-12-23 20:23:20 [information] [sTDOUT] Server: 7

Try This

 

    @Override
    public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int side, float hitX, float hitY, float hitZ) {
if (player.isSneaking())
    return false;

ItemStack test = player.getCurrentEquippedItem();
if (test != null && test.getItem() instanceof ItemBlock) {
    Block b = Block.blocksList[test.itemID];
    if ((b.getRenderType() == 0 || b.getRenderType() == 16 || b.getRenderType() == 31 || b.getRenderType() == 39) && b.getBlockBoundsMinX() == 0F && b.getBlockBoundsMinY() == 0F && b.getBlockBoundsMinZ() == 0F && b.getBlockBoundsMaxX() == 1F && b.getBlockBoundsMaxY() == 1F && b.getBlockBoundsMaxZ() == 1F) {
	TileEntityMiniatureBlock tile = (TileEntityMiniatureBlock) world.getBlockTileEntity(x, y, z);

	    tile.blockID = test.itemID;
	    tile.damage = test.getItemDamage();

	world.markBlockForUpdate(x, y, z);

	world.notifyBlocksOfNeighborChange(x, y, z, blockID);

	world.notifyBlocksOfNeighborChange(x + 1, y, z, blockID);
	world.notifyBlocksOfNeighborChange(x - 1, y, z, blockID);
	world.notifyBlocksOfNeighborChange(x, y + 1, z, blockID);
	world.notifyBlocksOfNeighborChange(x, y - 1, z, blockID);
	world.notifyBlocksOfNeighborChange(x, y, z + 1, blockID);
	world.notifyBlocksOfNeighborChange(x, y, z - 1, blockID);

	world.markBlockForRenderUpdate(x, y, z);

	System.out.println(world.isRemote ? "Client: " : "Server: " + world.getBlockLightValue(x, y, z));
    }
}

return true;
    }

 

Not entirely sure why you are changing the block ID and damage only on one side. I rearranged your code so it notifies blocks of an update first, then marks it for a lighting update.
