Im trying to make a flock of birds in a massive cage using boids. But they keep flying through the walls. How do I tell them to stay in the cage?

  1. Create your cage, I have used a box
  2. Select your box and enable Edit Mode (Tab)
  3. Keep the box selected and go to Mesh > Normals > Flip Normals
  4. Then go to the Physics tab, and enable the Collision modifier

Now your boids should interact with the cage. Hope it helps.
