Whenever a random encounter initiates, a gauge will appear on screen. And depending on the timing regarding a player’s Z button input, the battle will start off as a pre-emptive attack for the party, a normal battle, or even a surprise attack from the enemy.
Create or download an image with the filename “BattleAdvantage” within the Graphics\Pictures\ folder of your project.
When a player presses Z on these parts of the bar, different effects will occur:
Green – Pre-emptive Battle
Yellow – Normal Battle
Red – Surprise Attack
If the player fails to press Z in time, the battle will start with the enemy giving the player a surprise attack.
Note that the gauges vary depending on the party’s AGI compared to the enemy’s AGI. Advanced users can change the rate of pre-emptive rates versus surprise attack rates within the script.
I can see that and I'm sure Yanfly has as well. It would be perfect if it would appear randomly or after a certain amount of battles or even the boss battles too, I personally think if it had it for boss battle, holy shit that could be a difficult battle lol.
