# BackpackDisplay
Adds a tooltip to show what's in your backpack, shulker box or other container item.
Configurable of how to get contents for the container item.
The mod has out-of-the-box support for vanilla shulker boxes, storage drawers drawers, and forestry backpacks. You can add support to more items by writing custom rules in the mod's config.
Configurable options(See the mod's config):
- The items that the mod's tooltip should be shown for
- Position and color of the tooltip
- Optional hold or release a keybind to show the tooltip
## Config Format
`displayRules` is the main config of the mod. It lets you to add new container items to display the backpack tooltip, with the following format:
Format: `:[:meta]##`
meta is a comma-separated list for meta-values to match.
For example,`1,2,5-8` allows tooltip to show on the item with metadata 1,2,5,6,7,8.
When meta is absent, tooltip to show on the item ignoring meta.
Rule definition is according to the rule type selected.
### Paths
Path is commonly used in the rules, and have a format like `path.to.the.item`.
For example, in this NBT structure:
```
{"list":[{"key1":"value"},{"key2":"item"}]}
```
The path `list.1.key2` will get the tag "item" from it.
### List rule
Rule type: `list`
In this rule, items are all under a NBTTagList or a NBTTagCompound.
Rule definition:`path.to.the.list[;path.to.the.itemstack[;path.to.the.counts]]`
The last 2 paths is relative to the tag item in the list.
If the counts is absent, the count in the itemstack is used instead.
Example: Show contents when hovering a purple shulker box
```
minecraft:purple_shulker_box#list#BlockEntityTag.Items
```
### Single rule
Rule type: `single`
In this rule, an item is under a fixed path, with an optional external count value.
Rule definition:`path.to.the.itemstack[;path.to.the.counts[;calculations for the counts]]`
If the counts is absent, the count in the itemstack is used instead.
Example: Show content for every basic drawers in storage drawers mod
```
storagedrawers:basicdrawers:0#single#BlockEntityTag.Drawers.0.Item;BlockEntityTag.Drawers.0.Count
storagedrawers:basicdrawers:1,3#single#BlockEntityTag.Drawers.0.Item;BlockEntityTag.Drawers.0.Count
storagedrawers:basicdrawers:1,3#single#BlockEntityTag.Drawers.1.Item;BlockEntityTag.Drawers.1.Count
storagedrawers:basicdrawers:2,4#single#BlockEntityTag.Drawers.0.Item;BlockEntityTag.Drawers.0.Count
storagedrawers:basicdrawers:2,4#single#BlockEntityTag.Drawers.1.Item;BlockEntityTag.Drawers.1.Count
storagedrawers:basicdrawers:2,4#single#BlockEntityTag.Drawers.2.Item;BlockEntityTag.Drawers.2.Count
storagedrawers:basicdrawers:2,4#single#BlockEntityTag.Drawers.3.Item;BlockEntityTag.Drawers.3.Count
```
This rule supports further calculation to get the real item count if it's not in the tag directly but can be calculated from the values in the tag.
Calculations are a string starting with a operator in `+-*/^%` and followed by a path. The order of calculation is like that on a basic calculator that cannot input expressions.
All calculations is done in integer.
Example: Show content for compact drawers in storage drawers mod
```
storagedrawers:compdrawers#single#BlockEntityTag.Drawers.Items.0.Item;BlockEntityTag.Drawers.Count;/BlockEntityTag.Drawers.Items.0.Conv
storagedrawers:compdrawers#single#BlockEntityTag.Drawers.Items.1.Item;BlockEntityTag.Drawers.Count;/BlockEntityTag.Drawers.Items.1.Conv
storagedrawers:compdrawers#single#BlockEntityTag.Drawers.Items.2.Item;BlockEntityTag.Drawers.Count;/BlockEntityTag.Drawers.Items.2.Conv
```
