2816  * You may only fire items that "match" your missile launcher.
2817  *
2818  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2819  *
2820  * See "calc_bonuses()" for more calculations and such.
2821  *
2822  * Note that "firing" a missile is MUCH better than "throwing" it.
2823  *
2824  * Note: "unseen" monsters are very hard to hit.
2825  *
2826  * Objects are more likely to break if they "attempt" to hit a monster.
2827  *
2828  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2829  *
2830  * The "extra shot" code works by decreasing the amount of energy
2831  * required to make each shot, spreading the shots out over time.
2832  *
2833  * Note that when firing missiles, the launcher multiplier is applied
2834  * after all the bonuses are added in, making multipliers very useful.
