Join Todd Perkins for an in-depth discussion in this video Respond to collisions, part of iOS Game Development: Swift 2.0 and SpriteKit.
- So we've looked at which objects should physically collide…and react to other objects by bouncing off of them,…but what about responding to code when one object…hits a particular other object?…Let's look at how that works.…To talk about that, we need to discuss one feature…we've talked about very briefly up to this point.…I'll select this wall and let's look at the screen…and look at the feature Contact Mask.…Now we have all of these objects set to zero…and that's significant.…
The zero says, "Don't notify me…"when this object collides with another object."…We have our Ball set to one.…In other words, notify me when objects…collide with other objects.…The Contact Mask actually works…just like the Collision Mask.…We can define what objects, for example,…a ball collides with that we care about.…So by putting one in the Contact Mask,…what else has the number one?…Well, if we look at our GameScene,…the Collision Category for a wall is one.…
So what this is actually saying is…"Notify me in my code only…"when a ball collides with a wall."…
