Code:
ACTION_ENVIRONMENTAL_DAMAGE = "damaged";
ACTION_ENVIRONMENTAL_DAMAGE_DROWNING = "Drowning";
ACTION_ENVIRONMENTAL_DAMAGE_FALLING = "Falling";
ACTION_ENVIRONMENTAL_DAMAGE_FATIGUE = "Fatigue";
ACTION_ENVIRONMENTAL_DAMAGE_FIRE = "Fire";
ACTION_ENVIRONMENTAL_DAMAGE_LAVA = "Lava";
ACTION_ENVIRONMENTAL_DAMAGE_SLIME = "Slime";
STRING_ENVIRONMENTAL_DAMAGE_DROWNING = "Drowning";
STRING_ENVIRONMENTAL_DAMAGE_FALLING = "Falling";
STRING_ENVIRONMENTAL_DAMAGE_FATIGUE = "Fatigue";
STRING_ENVIRONMENTAL_DAMAGE_FIRE = "Fire";
STRING_ENVIRONMENTAL_DAMAGE_LAVA = "Lava";
