Breaking Blocks

mc.player.breakBlock()               // break what you're looking at (waits until done)
mc.player.breakBlockAt(x, y, z)      // break specific coordinate (recommended)

breakBlockAt is recommended — it finds the best face to hit and doesn't rely on crosshair position.

Placing Blocks

mc.player.placeBlock()               // place where crosshair points (may drift)
mc.player.placeBlockAt(x, y, z)      // precise placement at target coordinate
mc.player.jumpAndPlaceBelow()        // jump up and place block under feet

placeBlockAt computes the correct face automatically; ignore crosshair position entirely.

Using Items

mc.player.use()                      // single right-click
mc.player.useItem(32)                // hold right-click for 32 ticks (eat/bow/shield)
mc.player.startUse()                 // start holding right-click
mc.player.stopUse()                  // release right-click

Use case	Code
Eat food	mc.player.useItem(32) — ~1.6 seconds
Pull bow	mc.player.useItem(20) — full draw
Hold shield	mc.player.startUse() ... mc.player.stopUse()
