I want to cast spells based on a condition with lua programing ,example:

If the enemy pet HP > 500 than cast first spell

If the enemy pet HP < 500 and spell is cooldown than cast third spell else cast first spell.

You need good wow lua API and C# knowbase

To get health: 

        int enemyHealth = PetBattles.GetHealth(PetBattles.PetFaction.Enemy, PetBattles.GetActivePet(PetBattles.PetFaction.Enemy));
        int enemyMaxHealth = PetBattles.GetMaxHealth(PetBattles.PetFaction.Enemy, PetBattles.GetActivePet(PetBattles.PetFaction.Enemy));
        int enemyMaxPercent = enemyHealth * 100 / enemyMaxHealth;

 

thank you man

thank you,Hope to out API documentation
