How to disable collision between 2 SKPhysicsBody?

I would like to add a new superpower to my superhero in a spritekit game.

Once this superpower is enabled, he will be able to pass through any other SKPhysicsBody.

Setting the contactTestBitMask to 0x00000000 will only disable contact detection (didBeginContact:).

self.hero.physicsBody.contactTestBitMask = 0x00000000;

while setting dynamic to NO will let it pass through any SKPhysics body (but at the same time it will disable the gravitational force as well)

self.hero.physicsBody.dynamic = NO;

I want it to pass through the hero instead of just disabling the contact detection.

How to achieve this?

Add a variable to tell if you have the power-up, then set it to true when you run the function that activates your power-up.

In the didBegin function, you should then add a guard else { return } statement with the conditional being the variable name == true. The only thing to be careful of is to set the variable back to false when the power-up is disabled, or the power-up will continue forever.

(Just to be clear, this is in 2024 with slightly outdated Swift 5.5. I am guessing that a solution didn't exist in 2014, but I don't know as that was before I was born!)
