Detecting collisions in sprite kit

Question

I\'m trying to make a simple game with sprite kit. The basic idea is that there is one player who can jump to avoid blocks. But i have a problem I don\'t know how to make it

Answer 1

Handling collisions is a bit messy. :) There are a number of approaches, but one place you should start with is this fairly simple example from Apple. The readme provides a good intro, and then you can start poking around with the code.

Another approach (which Apple mentions in their guide) is to use Double Dispatching (see wikipedia for a long desc). I wouldn't start by trying to grok that approach right off however. It is a somewhat advanced approach given it depends on dynamic selectors and similar techniques to enable the magic to take place. However, even with that caveat, you can find a simple example someone put together on how to do it, along with a lot of supporting description here.
