GridInventory Issue

Plugins Plugin Development
1

So, I’m doing some updating on an old plugin and I’ve run across an issue. Back in the 5.0 API, all I needed to get the Hotbar and Grid inventory was:

Hotbar hotbar = inv.query(Hotbar.class);
GridInventory gridInv = inv.query(GridInventory.class);

I tried the following code below and got no errors when compiling:

Hotbar hotbar = inv.query(QueryOperationTypes.INVENTORY_TYPE.of(Hotbar.class));
GridInventory gridInv = inv.query(QueryOperationTypes.INVENTORY_TYPE.of(GridInventory.class));

when I executed the command that ran this code, though, I got the following error:

   [14:04:52] [Server thread/ERROR] [Sponge]: Error occurred while executing command 'dz join Stygia PAB' for source EntityPlayerMP['SalvadorZXA'/659, l='world', x=-396.36, y=90.00, z=818.19]: org.spongepowered.common.item.inventory.query.result.MinecraftResultAdapterProvider$MinecraftQueryResultAdapter cannot be cast to org.spongepowered.api.item.inventory.type.GridInventory

It seems like it ran okay for the Hotbar, but not for the GridInventory. Did I mess up, or is this an actual bug? Thanks.

Try

PlayerInventory pInv = (PlayerInventoy)inv;
Hotbar bar = pInv.getHotbar();
GridInventory mainInv = pInv.getMainInventory();

Its something like that. On my phone so cannot test it

I wish it were that easy :joy:

Query for GridInventory gets you all grids in that inventory.
In this case there are more than one grid so you cannot just cast to GridInventory.

I explained it here why: Inconsistent behavior in Inventory API? · Issue #1875 · SpongePowered/SpongeAPI · GitHub

If you are looking for the player inventory (grid+hotbar) without armor just query for MainPlayerInventory
and call getHotbar and getGrid on it.
