#    Enemy Summon Skill
#    Version: 1.0
#    Author: modern algebra (rmrk.net)
#    Date: May 8, 2010
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#
#    This script allows you to make skills for enemies where they can summon or
#   call additional enemies to the battlefield. This is NOT a summon skill that
#   can be used by actors - it can ONLY be used by enemies.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#
#    Place this script above Main and below Materials in its own slot in the
#   Script Editor (F11).
#
#    You can set up some basic configuration options at line 52. Please see the
#   surrounding comments to see what each does.
#
#    To create a summoning skill (again, this skill can ONLY be used by
#   enemies), all you need to do is put the following code (can be changed at
#   line 69 if you desire):
#
#      \SUMMON_ENEMY[enemy_id, x, y, chance]
#        enemy_id : the ID of the enemy it can summon
#        x : the additional pixels along the axis the summoned creature is from
#          its summoner. If omitted, it defaults to the value at line 64.
#        y : the additional pixels along the axis the summoned creature is from
#          its summoner. If omitted, it defaults to the value at line 67.
#        chance: of the potential candidates for summoning, how likely this one
#          will be chosen over the others. If omitted, this defaults to 1.
#
#    As you can probably tell, you can place a number of these codes in the
#   same notebox and thus you can make the same skill potentially summon
#   different enemies, and you can control that through the chance.
#
#  EXAMPLES:
#
#    A skill with its notebox set up like this:
#      \summon_enemy[1, 35, 45, 3]
#      \summon_enemy[2, 25, 35, 1]
#
#  Would, when it succeeds (which is governed directly by the hit ratio of the
# skill) summon the enemy with ID 1 (Default: Slime) 75% of the time and the
# enemy with ID 2 (Default: Bat) 25% of the time, and the position, if it is
# a slime would be 35 pixels to the right of the summoner and 45 pixels down,
# or if it is the bat, then 25 pixels to the right of the summoner and 35
# pixels down. The chances are 75-25 because 3 + 1 = 4, which means that 3/4
# times the slime will be summoned and 1/4 times the bat will be summoned.

#  Summary of Changes:
#    new constant - MAES_VOCAB_SUMMON_FAILURE; MAES_MAX_TROOP_SIZE;

MAES_DEFAULT_X_PLUS = 35
# The default y offset for a summoned enemy from its summoner. If you manually
#  set this in the note box, this value will not be used.

Thanks

Known Compatibility Issues

No currently known incompatibility issues, but I suspect it will be incompatible with most custom battle scenes that deviate significantly from the default.

Demo

Please see attached demo.

Author's Notes

Just playing Skies of Arcadia, and liked this ability that some enemies would have. Also, I realize that this effect can be done with events, but I figure it is a lot easier to do with a script and can be a little more random as well, which is a good thing.

[Zylos]

Uh oh, monster breeding. o_o *flees*

[Cascading Dragon]

Just wondering, but if I edited this script to make it compatible with Yanfly's Melody Battle System, should I send you the edit for you to post on here?

[Zero2008]

OMG Modern this looks PERFECT!
This will go perfectly with my EarthBound game! Thanks!

No, you don't need to. I would appreciate if you posted it in this thread so that other people could find it, but no, you can do with it as you like.

[LuKo]

great Algebra, another cool and uncommon script^^

This give an really coll addiction to the battle.

Nice job^^

[cozziekuns]

This script looks awesome, though I thought the script could allow you to change the hue of the monster summoned -.-

It's still cool.

[Grafikal]

You could always summon the same monsters with a different hue. The only difference is that you'd have to make it a separate enemy in the database instead of coping an existing one and changing the color via the script.

[cozziekuns]

That would work, but it'd clog up some monster space. Oh well, the give us 1000 spaces, so I guess making hue recolours wouldn't hurt.

[Grafikal]

lol. I generally make hue adjustments to enemies for new monsters. So instead of having 100 different monsters, it's much easier to have only 50, then having 50 recolors of them all representing a 'more powerful' version of the one before it - or something similar.

[thanatos2k1]

Ok, so this looks like its nearly what I need, especially what I saw with the slimes..  Now, what I want to do is if an actor uses slash or pierce weapons to a slime it splits and the hp of the original is halfed with the new one.

So, if Slime A has 62 HP and an actor hits it:

"The slime has split in half, spawning a new slime!"

Now there is 2 slimes, A + B and they both have 31HP.

Can this be done with this script?

[Mr G W]

theres a small issue, if the summoner keeps summoning new monsters they eventually start appearing offscreen, even if you kill the older ones.

[bdcam]

Can this be used with ABS 9?

[DoctorTodd]

I know your new so you should probably read the rules first because that was a pretty big necropost. Any way I positive it won't unless you basically rewrote it.

Known Compatibility Issues

No currently known incompatibility issues, but I suspect it will be incompatible with most custom battle scenes that deviate significantly from the default.

[modern algebra]

It's actually OK to necro resource topics when it's on topic, but DoctorTodd is right that it won't work with any ABS. Depending on the nature of the ABS though, I would suspect that it would be possible to do something similar through eventing.

[pacdiggity]

Hey MA, would it be cool with you if I ported this to VXA? It seems like a pretty easy port, I'm bored, and it's a cool script.
I know that you're gradually converting some of your scripts, but I thought you could use a hand in the process

[modern algebra]

Sure, go right ahead!

[Darkrai1276]

very nice, coud defently get some use out of this, very good for enemy's that can multiply and is excellent move for my fina boss
i give it a 9/10= perfect
