When a BUILDING is successfully Invadeed, the invading player may capture some RESOURCEs from the invaded player. For each type of RESOURCE specified in the ``Capture val'' column of Table 4, the game engine generates a random integer between 0 and the specified number. The resulting number of FRUs of that resource are deducted from the invaded player's BANK and added to the invading player's BANK.
For example, suppose that Alice owns a Fortress, and Bob successfully Invades that Fortress.2 Bob will receive between 0 and 3 food and between 0 and 3 iron. Suppose the game engine generates the values 0 and 2. Then Alice loses 2 FRUs of iron from her BANK, and Bob's BANK gains those 2 FRUs of iron.
