cannon.js detecting collisions without any physical contact occurring

I'm currently working on a basic car game using cannon.js and I've hit a roadblock.

The Goal:

My objective is to detect collision between the car and another object (such as a sphere) without applying any physical forces to either object.

For instance, I want to update the score or trigger certain events upon collision, but I don't want the objects to interact physically.

What I Have Tried Unsuccessfully:

I attempted to use the following:

chassisBody.addEventListener("collide",function(e){ "mycode"};

in conjunction with grouping like this:

var GROUP1 = 1; etc..

However, I believe the purpose of groups is to specify which objects should collide or not, but in my case I need them to "collide" without causing any physical impact, only to register that they intersected so I can implement scoring logic, etc.

(I included the threejs tag just in case someone who works with it might find this helpful since it's part of my project)

EDIT 2022:

If you're curious, here's how the code looked back then, though be warned, it's an outdated version :)

Answer №1

I came across the code snippet below on a website and decided to give it a try. I used your event listener callback, and everything worked perfectly.

To prevent the rigid body from responding to collisions, simply set its collisionResponse property to 0:

b2.collisionResponse = 0; // disable collision response
b2.addEventListener("collide", function(e){ console.log("sphere collided"); } );
