Can't disable physics in Sprite Kit

Question

I have two nodes one near another. And I want one node to be on top of another when I tap. I do so like this:

SKAction *moveUp=   [SKAction moveByX:0 y:25 duration:0.1];
SKAction *moveDown= [SKAction moveByX:0 y:-25 duration:0.1];
SKAction *playerSequence = [SKAction sequence:@[moveUp,moveDown]];
[self.player runAction:[SKAction repeatAction:playerSequence count:1] withKey:@"attack"];

And instead I get that one node pushes the other (bots nodes created via editor and both body type is set to none).

I tried adding these to didMoveToView on both nodes:

node.physicsBody.dynamic = NO;
node.physicsBody.collisionBitMask = 0;
node.physicsBody.contactTestBitMask = 0;
node.physicsBody.affectedByGravity = NO;

I even tried setting velocity to 0 on Update. And still no effect.

One couldn't tell unless you show the code where you create those nodes. — El Tomato, Nov 13 '15 at 13:55
I create nodes with drag and drop, via xcodes editor. (.sks file) — HelloimDarius, Nov 13 '15 at 14:15

Set your bit masks in -(void)didBeginContact:(SKPhysicsContact *)contact as shown in this post.

I think you have a timing issue if you set the bit masks in didMoveToView because only one of those will be run at a time and both physics bodies will need to mutually agree not contact each other.

You have to set the physics body to nil:

node.physicsBody = nil;
