Gravity not working for setBlock()

[rob_bb]

Hi, I have a block that extends from BlockSand. 

 

When placed by the player it behaves as expected and falls if it is not on another block. but when my mod does this:

 

boolean result = world.setBlock(x_shift, y_shift, z_shift, Bloc_ID, metadata, flag);

 

The block remains floating in the air.

 

How do I make it fall if it needs to?

Based on this

 

Flag 1 will cause a block update. Flag 2 will send the change to clients (you almost always want this). Flag 4 prevents the block from being re-rendered, if this is a client world. Flags can be added together.

 

I have it set to 3

Here it is, but it's pretty standard I think.  I am very new to modding.

Is it because I use world rather than player to set the block?  I just thought of it but am at work so can't test it for hours yet :-(

 

Are there was to simulate the player placing a block?

world.setBlock(x, y, z, block, meta, 3);

 

If that's not sufficient though, you can always schedule a block update manually.

 

world.scheduleBlockUpdate(x, y, z, triggeringBlockID, numTicks);

Same result, the blocks (sand) remain floating in the air instead of falling back to the ground.

I am watching for ItemTossEvent like this:

 

    @ForgeSubscribe

    public void onItemToss(ItemTossEvent event) {

    if (event.isCancelable()) {

 

 

and in there if player tosses my item I do a scan of the area in front of the player, pick a random block of air and place the block there using this line:

 

    place_result = world.setBlock(x_shift+x, y_shift+y, z_shift+z, BlockIDs.BANANA_SKIN_BLOCK_ID, metadata, flag);

 

In the above line, flag is set to 3

 

I then cancel the event with:

 

  event.setCanceled(true);

 

I have no @side anotations in this class.

I have been digging a little deeper, and World.java file I have has this as the scheduleBlockUpdate() method.

 

/**

    * Schedules a tick to a block with a delay (Most commonly the tick rate)

    */

    public void scheduleBlockUpdate(int par1, int par2, int par3, int par4, int par5) {}

 

 

So it does nothing.  So how do I get it to call  the method on the server rather than on the client?

The answer is perhaps so simple that no one thought to mention it.  In my ItemTossEvent I was simply grabbing  a world from the client, not from the server.

 

The solution is to get a world from the player like this:

EntityPlayer player = event.player; 
World world = player.worldObj;   //  Not from Minecraft.getMinecraft().theWorld;

That would be a function that's implemented by a subclass.  Because if that function did actually nothing, a hell of a lot of stuff wouldn't work (most redstone, for instance).

Yes,  hence it being important how you get your world object, Minecraft.getMinecraft().theWorld; retruns a world obejct that does nothing on shcheduelBlockUpdate() so calling that does nothing, load World.java and WorldServer.java for more info.
