What happened here.. It was working before.. Now after an attack the enemy's HP automatically = 0.. The enemy's HP variable= $Enemy_HP btw. The damage displays correctly..

Initial observation:

 

$EnemyDamage3= round($EnemyDamage3 / 1.25);

 

Since you set EnemyDamage3 to 0 when there's insufficient Chakra, you're going to cause a division by zero.

 

Honestly, I'd be surprised if anyone has time to dig through all that code. Have you tried a 'dry run'? You will probably find any bug quicker than we will.

that is a problem.. But it wasnt 'the' problem. Because even with sufficent chakra, it does the same thing. For some reason all of its HP depletes. And well, it was working before and randomly stopped... I dont know why.. Thats why I want you guys to help.
