Description
The default VX Ace's enemy targeting behavior just pick a random target for
any actions.
This script adds some AI targeting priority. With this script, the enemies
become able to pick a target based on the action specific priority.
--------------------------------------------------------------------------------
History
v1.0 (2014/03/20)
Initial release
--------------------------------------------------------------------------------
Terms of Use
- You are free to use this script for non-commercial projects.
- For commercial projects, at least contact me first.
- This script is provided as-is. Don't expect me to give support.
- Reported bug will be fixed, but no guarantee on requested features.
- No guarantee either for compatibility fixes.
- Give credit to Shad3Light (me), and do not delete this header.
--------------------------------------------------------------------------------
Installation
Put this script below ¥ Materials and above ¥ Main Process.
If there are scripts that overwrite the aliased methods below,
put this script below said script.
--------------------------------------------------------------------------------
Usage
In an enemy notebox, you can add some tags.
<target [action_id] [shortcut]>
where [action_id] corresponds to the enemy's action list, and [shortcut]
corresponds to one of the implemented targeting priority method.
Example:
<target 1 high_hp>
This will make the enemy target the battlers with the highest HP value when
using action number 1 (by default Attack).
<target 2 low_hp_rate>
This will make the enemy target the battler with the lowest HP percentage when
using action number 2. If the action no. 2 is set to Heal, the enemy will
proceed to heal its ally with the lowest percentage of health.
Available targeting shortcut is as follows:
low_hp
high_hp
low_hp_rate
high_hp_rate
low_mp
high_mp
low_mp_rate
high_mp_rate
low_tp
high_tp
low_tp_rate
high_tp_rate
self
not_self
If you want to make your own targeting condition, use
<target eval [action_id]>
[eval]
</target eval>
where [eval] is a ruby expression that takes returns -1, 0, or 1.
In the eval, a and b denotes the battlers that would be sorted.
For example, to make the enemy prioritize Eric when doing its ultimate skill,
the tag will be
<target eval 8>
if a.name == "Eric"
-1
elsif b.name == "Eric"
1
else
a.hp <=> b.hp
end
</target eval>
Do note that target selection is done at the start of the turn, like actors.
The enemy will not suddenly change target mid-turn, for example if its target
had already healed.
Also, TGR have no effect on acquiring target.
