To unlock the achievement now, you must build a dynamic trap that tricks the new AI and keeps the mob alive. Required Materials
In the early versions of Lovely Craft, the Piston Trap achievement was awarded when a player successfully immobilized a mob using mechanical pistons. The game's code looked for a specific triggers: a piston extending, a mob entering a specific coordinate grid, and the mob's movement speed dropping to zero.
The update fixed the collision detection between the beads and moving pistons. Now, when you drag the beads against a character’s hitbox while a piston is running, the game no longer “resets” them or forces a teleport. The beads simply stay where they are, and no clipping occurs.
