Changing AI max health only

Hello guys, having a hard time changing AI health only, I tried the following code:
                if (player == 1) {
                    if (this.namePlayer1 != null) {
                        this.namePlayer1.text = character.characterName;
                        print (character.lifePoints);
                        if (characterIndex == 1) {
                            character.lifePoints = 1000;
                        }

                    }

Is there a better way to do this? thanks! really appreciate the help
