I need a few ABS RGSS command

[Trix]

Hi.

I need help with some RGSS commands. I'm trying to make ABS in RGSS, but my knowledge in this isn't really big. I know some things, but with this few below I need help.

How can i write (and use, if it possible to explain it to me) these commands & conditional branches in RGSS:

if player's weapon is included in array $ranged_weapons


if player have item included as a player's weapon missle in array $missles


create event with graphic that's set as player's weapon's missle


if missle's event coords are equal to enemy's event (enemy is set in class ABS_Enemy)


if @hp <= 0 and in "/Characters" folder is file named: enemy battler name + "_Corpse.png" change this event's graphic into this charset that's set few words back, else erase event


decrease actors HP ($game_party.actors[0]) by the enemy's attack power (after decreasing it by actor's pdef)

Thanks in advance for helping me


P.S. I'm Polish, so sorry for any mistakes in English.
