Javascript, Matter.js: Disable Collision For One Body

As already mentioned in the title, I am looking for a way, to disable every collision of a body in Matter.js. It should still be linkable with Constraints, and there should be the

Solution 1:

You can use collision filters, like so:

const body = Matter.Bodies.rectangle(100, 100, 50, 50);
// turns off collisions
body.collisionFilter = {
  'group': -1,
  'category': 2,
  'mask': 0,
};

From the docs:

If the two bodies have the same non-zero value of collisionFilter.group, they will always collide if the value is positive, and they will never collide if the value is negative.

Using the category/mask rules, two bodies A and B collide if each includes the other's category in its mask, i.e. (categoryA & maskB) !== 0 and (categoryB & maskA) !== 0 are both true.

Solution 2:

see

Matter.IBodyDefinition.isSensor

in order to disable physical collisions for the Body. The Body can still be used as a sensor for collisions.
