An item throw is an attack, performed when the character is holding an item, and then pressing the grab button. Depending on the Analog Stick's position, the direction and strength of the throw will be different. The player can throw an item while in midair or on the ground.
Directions and strength
The player may choose to throw the item in one of 5 directions, although the last is not exactly a throw: up, left, right, down, and none. When the grab button is simply pressed without a direction being inputted, the fighter will drop the weapon, if it can be dropped. It is this feature when used in mid air that forms the basis for bat dropping.
If a direction is inputted, the fighter will throw it in the same direction. The item can be thrown in 2 different strengths: smash (grab and direction are pressed at the same time) or tilt (the direction is held before pressing grab). While on the ground, the player can even throw an item while dashing.
The damage done by thrown items is usually dependent on how fast the item is moving at the time of impact; this is the only reason smash throws are stronger than tilt ones. In SSB64, the formula is
There is a small delay animation in each character prior to throwing an item. This delay is not equal in all characters. Some characters including Link, Mario, and Donkey Kong throw their items more quickly than Marth, Pikachu, and Bowser.
