An '''activator rail''' is a type of [[Minecraft:rail]] that, if [[Minecraft:powered]], can eject [[Minecraft:entities]] from regular [[Minecraft:minecart]]s, lock [[Minecraft:hopper minecart]]s, ignite [[Minecraft:TNT minecart]]s, and activate the command in a [[Minecraft:command block minecart]]. If not powered, it can only unlock locked hopper minecarts.

Activator rails (and other rails) can be used as "roads" for [[Minecraft:minecart]]s. A minecart that enters an activator rail's space from either end of the activator rail continues to move, losing only a little velocity (which can then be increased again with [[Minecraft:powered rail]]s). A minecart that enters an activator rail's space from the side turns east or south (depending on the activator rail's orientation), or in the downward direction for a slanted activator rail.

A hopper minecart stops picking up items in the same tick it touches an active activator rail or in the same tick the inactive rail it is standing on is powered (it does not collect the item it could have taken from a container above in the same tick the activator rail turns on and takes the first item in the same tick the rail turns off again).

Template:Infobox block An activator rail is a type of Minecraft:rail that, if powered, can eject entities from regular Minecraft:minecarts, lock hopper minecarts, ignite TNT minecarts, and activate the command in a command block minecart. If not powered, it can only unlock locked hopper minecarts.

Obtaining

Breaking

The correct tool to break an activator rail is a Minecraft:pickaxe. It will always drop itself when broken, regardless of the tool used. Script error: No such module "breaking row".

Generated loot

Script error: No such module "lootChest".

Crafting

Template:Crafting

Usage

An activator rail can be used as a rail and as a redstone component.

To place an activator rail, {{#vardefine: control | right click on mouse or left trigger on gamepad }}use an activator rail item while pointing at a surface facing the space the activator rail should occupy. An activator rail can be placed on:

An activator rail cannot be attached to the side or bottom of any block, but attempting to make such an attachment may cause the activator rail to attach to the top of a block under the destination space. For example, if a fence is on the ground, attempting to attach an activator rail to the side of the fence causes the activator rail to be attached to the top of the ground next to the fence instead.

When placed, an activator rail configures itself to line up with any adjacent Minecraft:rails (including detector rails, powered rails, and other activator rails), as well as adjacent rails one block up. The behaviors in Template:Editions diverge in the following ways.

in Template:Editions:

If there are two adjacent rails on non-opposite sides, or three or more adjacent rails, or no adjacent rails at all, an activator rail aligns itself in the direction the player is facing. If an existing activator rail is connected to only one other rail or none at all, and a new rail is placed perpendicular to the activator rail, then the activator rail aligns itself in the east-west direction (if it isn't already facing that way). If a rail it would align with is one block up, an activator rail slants upward toward it (with multiple options to slant upward to, an activator rail "prefers" west or south). Other configurations can be created by placing and removing various rails.

Template:R

in Template:Editions:

If there are two adjacent rails on non-opposite sides, or three or more adjacent rails, an activator rail aligns itself in the east-west direction. If there are no adjacent rails, an activator rail aligns itself in the north-south direction (but if a rail is later placed to the east or west, the activator rail re-orients itself in the east-west direction even if it is already connected to another rail to the north or south). If a rail it would align with is one block up, an activator rail slants upward toward it (with multiple options to slant upward to, an activator rail "prefers", in order: west, east, south, and north). Other configurations can be created by placing and removing various rails.

It cannot be placed suspended in midair, even with commands.<ref>Template:Bug</ref>

Rail

{{#vardefine:params|0 }}Template:Hatnote

Activator rails (and other rails) can be used as "roads" for Minecraft:minecarts. A minecart that enters an activator rail's space from either end of the activator rail continues to move, losing only a little velocity (which can then be increased again with powered rails). A minecart that enters an activator rail's space from the side turns east or south (depending on the activator rail's orientation), or in the downward direction for a slanted activator rail.

Redstone component

{{#vardefine:params|0 }}Template:Hatnote

Activator rails can be used to affect minecarts that travel over them.

Activation
An activator rail is a redstone mechanism and can be activated by:
  • an adjacent active power component (for example, a redstone torch, a block of redstone, a daylight sensor, etc.)
  • an adjacent powered block (strongly-powered or weakly-powered)
  • a powered redstone comparator or redstone repeater facing the activator rail
  • powered redstone dust configured to point at the activator rail, or configured as a plus sign. An activator rail is not activated by adjacent powered redstone dust that is configured to point in another direction.
  • in Template:Editions, activator rails can only activate on input/consumer redstone ticks (C-tick).
An activated activator rail also activates any adjacent activator rails it is connected to, up to eight away from the original activation source. Thus a single activation source can activate up to 17 rails (one original in the middle and eight on either side). An activated activator rail does not activate adjacent rails not connected to it.
Activation and deactivation are instant and occur in the same gametick the power source turns on or off (any eventual delay depends on the power source).
Behavior

An activator rail affects minecarts above it with varying effects that occur as soon as any part of the minecart is on the activator rail.

An active activator rail:

  • starts shaking, and ejects mobs (including players) from minecarts — the destination location is picked the same way as when dismounting a minecart
  • repeatedly activates minecarts with command blocks — a command block minecart executes its command every four game ticks until the command block minecart is no longer on the activator rail
  • disables minecarts with hoppers — a disabled hopper minecart cannot pick up items it travels through until it is enabled by an inactive activator rail (or until it is broken and re-placed)
  • primes minecarts with TNT — primed TNT minecarts explode after four seconds with an explosive power proportional to their speed over the activator rail.

An inactive activator rail enables minecarts with hoppers — an enabled hopper minecart picks up items it travels through until it is disabled by an active activator rail.

A hopper minecart stops picking up items in the same tick it touches an active activator rail or in the same tick the inactive rail it is standing on is powered (it does not collect the item it could have taken from a container above in the same tick the activator rail turns on and takes the first item in the same tick the rail turns off again).

Mob interaction

Like other types of rails, spiders, cave spiders, and Minecraft:wardens are the only land mobs that can walk onto activator rails.Template:Only

Piston interactivity

An activator rail can be pushed by a Minecraft:piston, and can be pulled by a sticky piston. However, it breaks and drops as an item when it is unsupported due to being moved.

Trivia

  • The Minecart shake animation when passing over an activator rail is caused by the rail actively damaging the Minecart. This can be noticed by attempting to punch a Minecart right after it plays this animation, seeing how the Minecart is inmediately destroyed.
