Class: TripWireTripAfterEventSignal

Manages callbacks that are connected to when a trip wire is tripped.

Example

import { Vector3, world, BlockPermutation, TripWireTripAfterEvent, system } from '@minecraft/server';

const overworld = world.getDimension('overworld');
const targetLocation: Vector3 = { x: 0, y: 0, z: 0 };

// set up a tripwire
const redstone = overworld.getBlock({ x: targetLocation.x, y: targetLocation.y - 1, z: targetLocation.z });
const tripwire = overworld.getBlock(targetLocation);

if (redstone === undefined || tripwire === undefined) {
    console.warn('Could not find block at location.');
} else {

redstone.setPermutation(BlockPermutation.resolve('redstone_block'));
tripwire.setPermutation(BlockPermutation.resolve('tripwire'));

world.afterEvents.tripWireTrip.subscribe((tripWireTripEvent: TripWireTripAfterEvent) => {
    const eventLoc = tripWireTripEvent.block.location;

    if (eventLoc.x === targetLocation.x && eventLoc.y === targetLocation.y && eventLoc.z === targetLocation.z) {
        console.warn(
            'Tripwire trip event at tick ' +
                system.currentTick +
                (tripWireTripEvent.sources.length > 0 ? ' by entity ' + tripWireTripEvent.sources[0].id : ''),
        );
    }
});
}
