Checking Actor Equipment Via Script

I'm not exactly sure how to do this. Is there a way to check via scripting if an actor has a certain piece of armor/weapon/shield/accessory equipped? And if so, how do you check for that? I'm going to use the code as part of Game_Battler calculations.

Code: [Select]

aGame_Actor.weapon_id # Weapon 1
aGame_Actor.armor1_id # Weapon 2/Shield
aGame_Actor.armor2_id # Helmet
aGame_Actor.armor3_id # Armor
aGame_Actor.armor4_id # Accessory

Remember to check for aGame_Actor#two_swords_style before checking aGame_Actor.armor1_id, just for those rare occasions.

Gotcha, thanks.
