Hi @mortal_phoenix,

To set a p2.js body to act as a trigger set the Sensor option to true:

From there you can use the following method to listen to contact events and filter your trigger e.g. with its name:

// --- this should be added to a script attached to your p2 World entity
this.entity.script.p2World.world.on("beginContact",function(evt){

    if( evt.bodyA.entity.name === 'Trigger' || evt.bodyB.entity.name === 'Trigger'){
        // set velocity to zero
    }

}, this);

This tutorial explains, among other things, how p2 physics work:
