findnearactor <actor> <distance> <gamevar>

Gets the actor ID of the closest <actor> within <distance> into a <gamevar>. If no actor within range is found, the gamevar is set to -1. The input for <actor> may be its tile number (example: 2000) or its defined name (example: PIGCOP). The <distance> will be determined on the x and y plane only; for finding actors on the x, y, and z axes use findnearactor3d instead.

By getting the actor ID of a nearby actor, the current actor can use getactor/setactor to edit the properties of the target actor or getangle to face the target actor, among other potential uses.

For non-actor sprites or asleep actors, use findnearsprite.
