Whyzard

Works with Jade (optional). No Jade? You get a small line under your crosshair instead.

Look at a block and see why it isn’t working, and how to fix it.

What it shows

Furnaces (and Iron Furnaces): no fuel, output full, wrong furnace, can’t be smelted, exact time left
Crops and saplings: too dark, dry farmland, needs a 2×2, no room
Sugar cane, cactus, bamboo: no water, blocked on top, fully grown
Beds: too far, blocked, monsters nearby, how many players must sleep
Hoppers: chest full, wrong side, pointing at nothing
Brewing stands: no fuel, ingredient does nothing, exact time left
Spawners: too bright, no room, too many mobs, next try
Trial spawners and vaults: cooldown left, already opened

How to use it

1. Look at a block. The answer shows up by itself.
2. Press K for the full story and the fix.
3. Want it quieter? Turn on Quiet mode in the config: it only speaks up when something is wrong.

Only reads, never changes gameplay, never goes online. Says how sure it is: Confirmed or Likely.

Coming next

More vanilla: portals that won’t link, redstone that won’t power, villagers without a job, anvils that say “Too Expensive”.
Planned tech mods (no dates yet): Create, Mekanism, AE2 + ExtendedAE, Modern Industrialization.
