Easy peasy! To actuate blocks in Terraria, you first need to grab yourself an Actuator from a Mechanic NPC. Place those actuators on the blocks you wanna make passable. Then, hook 'em up to a switch, lever, or pressure plate using wires. Flip the switch and voila, passable blocks! It's like magic, but with more steps.
I spent hours building my secret base using actuators! Best way to hide your loot or create cool door mechanisms. Buy actuators from the Mechanic, place them on the blocks you want to toggle, connect them with wires to a control device, and bam - instant stealth mode for your blocks.
