How do you catch a bore on the sims 2 castaways?

you have to craft an obsidian tipped speared first. Then when you have the weapon in your inventory and you happen to be in the same area with a running boar, simply get in front of his path. He will stop and a picture balloon will pop up in your sims head. Then a big fight between your sim and boar will take place in a cloud of dust. When you are successful, you end up with the meat, the tusk & skin (which you can use for fashion and grooming).
