![]() ![]() However, redstone components only update other blocks a maximum of two spaces away, but quasi-connectivity can create situations where a piston should be activated from a redstone component three spaces away. When redstone components change their state, they update other redstone component around them of the change so that they can update their state in response (for example, when a lever turns on, it updates nearby components that they should now be powered or activated). Where quasi-connectivity gets complicated is that it can cause states where a piston should be activated by QC … but doesn't know it. The Update Problem - The lever can activate the piston by quasi-connectivity, but is too far away to update the piston when it changes. powered redstone dust configured to point at the mechanism component (or on top of it, for mechanism components that can support redstone dust, but not beneath it), or adjacent "directionless" redstone dust a mechanism component is not activated by adjacent powered redstone dust that is not configured to point at it.a powered redstone comparator or redstone repeater facing the mechanism component. ![]() an adjacent powered opaque block (either strongly-powered or weakly-powered), including above or below.Levers and buttons don't power blocks they aren't attached to, but can activate mechanism components in any space next to them. an adjacent active power component, including above or belowĮxceptions: a redstone torch does not activate a mechanism component it is attached to, and a piston is not activated by a power component directly in front of it Examples: Redstone torches don't power blocks that aren't above them, but can activate mechanism components in any space next to them.Most Minecrafters would just say they are "powered", but it can be useful to distinguish powered and activated.Īll mechanism components are activated by: Mechanism components (pistons, doors, redstone lamps, etc.) can be activated, which causes the mechanism component to do something (push a block, open the door, turn on, etc.). Rather than repeating "dispensers, droppers, and pistons", this tutorial discusses only pistons, but everything discussed here applies to dispensers and droppers as well.Īctivation of Mechanism Components - Mechanism components can be activated by power components (for example, redstone torches), powered blocks, redstone dust, repeaters, and comparators (not shown), but only if configured correctly.īefore discussing activation by quasi-connectivity, let's review more general methods of activation. Other terms used for this property include "connectivity", "piston connectivity" (as the property originated with pistons), "indirect power" (but that term is also sometimes used for activating mechanism components with an adjacent powered block), and "BUD-powered" (although quasi-connectivity and block update detectors are not synonymous). Quasi-connectivity can be abbreviated as QC. "Quasi-connectivity" means the block's activation is quasi-connected to the space above itself ("quasi-" means "seemingly" or "apparently"). While quasi-connectivity can be difficult to work around sometimes and might seem like a bug, it is officially recognized as a feature that "works as intended" and does make some builds much easier (for example, piston walls). Quasi-connectivity is a property of dispensers, droppers, and pistons that allows them to be activated by anything that would activate the space above them, no matter what is actually in that space.
