Know what you are looking at with this lightweight UI mod called What is That by mod developer SilentChaos512.
What is the Mod About?
WIT is a lightweight UI mod similar to WAILA (What Am I Looking At) Mod. The mod provides a simple display that shows information about blocks and entities when you look at them. The mod also has its API. The mod can display the following: Name of the block/ entity as well as from what mod it is from, ID Metadata and un-localized name, Harvestability info, contents of inventories, extra information, and more.
Should You Install it?
The mod is very similar to WAILA but features a different “flavor” and design. The API allows the player to adjust what is displayed, which is handy and helpful.
Features
HUD Overlay
A little window pops up to tell you about whatever your cursor is on. You need to be within a few blocks of the target. Some things WIT currently displays:
The name of the block/entity and the mod it is from.
Registry name (“minecraft:stone”, “minecraft:villager”, etc.)
Harvestability info
Indicates tile entities with “[TE]” after block name
Contents of inventories that sync with the client, including Storage Drawers
Extra information can be added by mods
Look at blocks and entities for basic information. Sneak for more information. The background also has a fancy sliding animation, just for fun.
Sticky Time
The version for Minecraft 1.13 adds a “sticky time” to the HUD overlay. The overlay sticks around for a short, configurable time whenever something goes out of range. By default, the sticky time for entities is much longer than that of blocks. This should help with getting details on fidgety mobs or during combat.
Tooltips
WIT also displays the mod name, tool durability and speed, food values, and ore dictionary entries (1.12.2 and earlier) in item tooltips. You typically need to hold a shift to see these. Support for 1.13 item tags is being considered, but it may not be practical to implement.
Config
What is displayed, whether or not it requires sneaking, and most elements’ formatting (color) can be changed in the config file.
