within Radius

Sets the farthest (maximum) distance from this selector’s base coordinates. This is a useful way to change the maximum distance of an existing target selector.

Only mobs that are within this distance from the selector’s coordinates are selected.

mobs.target(ALL_ENTITIES).withinRadius(0);

Parameters

• radius: the maximum distance (in blocks) for this target selector, like: 5

Example

First: This code creates a target selector to select all chickens within 5 blocks of the current player’s world position. The target selector is stored in a variable called item.

Then: The target selector is changed to select chickens within 30 blocks of the player, instead of 5.

Finally: The selector is used in a teleport command. Because we changed the selector’s radius, all chickens now within 30 blocks (not 5 blocks like before) of the current player are teleported.

let item: TargetSelector = null;
item = mobs.near(
    mobs.entitiesByType(CHICKEN),
    player.position(),
    5
);
item.withinRadius(30);
mobs.teleportToPosition(
    item,
    pos(0, 10, 0)
);
