They use an `item_attribute` macro that defines many pieces of data at once: - **price:** The price in Marts. Prices range from ¥0 to ¥65535 ($FFFF, the maximum value of a two-byte quantity). Items can be resold for half the price. -- **held effect:** The effect when held by a Pokémon. Usually `HELD_NONE`, except for items like Leftovers. The `HELD_*` constants are defined in [constants/item_data_constants.asm](../blob/master/constants/item_data_constants.asm). Creating a new held item effect is beyond the scope of this tutorial, but you can look at which effect constants are used by existing items to see what they do. +- **held effect:** The effect when held by a Pokémon.

Usually 0, but some item effects use this parameter. For instance, BrightPowder's parameter of 20 is interpreted by `BattleCommand_CheckHit` as an extra 20/256 (~7.8%) chance to miss a move. - **property:** Controls whether you can select and/or toss the item. `NO_LIMITS`, `CANT_SELECT`, `CANT_TOSS`, or `CANT_SELECT | CANT_TOSS`.

When a Pokémon is traded via Time Capsule from RBY to GSC, the byte in its data structure that represents its catch rate is interpreted as its held item. (A catch rate byte no longer exists in GSC, since that's part of base data.) For example, Jigglypuff's catch rate is 170, or $AA, so it holds a Polkadot Bow when traded to GSC because `POLKADOT_BOW` is $AA. |
