There's 2 items, 2 events, and a variable: a ball to throw, the ball with the creature, their respective events, and the variable for the odds (again, see above). You can also make some flashy animations for it; I suggest using Earth 1, which throws a rock at the target, for visuals. We'll use Arbok as our target, 'cause they're fun.
both items call up a common event, which work them. But there are differences:
capture ball-one enemy, only in battle, ignore defence, add incapacitate, consume-yes, common event-capture
Arbok ball-occassion-always (you can add him to your party in-battle! ) , consume-no,
That's about it....As you can see, it's very simple, and I'm sure there are better ones out there...I just didn't see any in this forum.
UPDATE : Remember how everyone was like "we can't tame more than one monster" ? Well, I FOUND A WAY. I "captured" 2 of the 3 enemies in the opposing party and added them to mine IN BATTLE. That's right, I took 2 enemies and added them to my party during the fight.
Troops tab-when enemy/monster x - health = 10% or less
show choices-catch, kill
call common event (the one above)
decrease HP enemy/monster x
- (nothing, since you're just finishing them off. Incidently, I have another event about that...)
you need to create one of these troop event tabs for each monster in the party (and have the slots open to add them to yours). The x corresponds to the monsters number ( 1 - 8 ) , and if you don't have the slots open, you can get around this by having them become items (again, see above) , which you get when the monster dies (even during the battle) , giving you the option to either add them during the battle (I'm pretty sure that you can call them back, too ) , or add them afterwards.
Take THAT, other taming systems!
