AnimatorConditionMode

Параметры для указания оператора равенства или сравнения для оценки условия.

Режим condition соответствует оператору, используемому для оценки условия parameter. Оператор либо проверяет, является ли значение параметра true или false (см. AnimatorConditionMode.If и AnimatorConditionMode.IfNot), либо сравнивает его со значением threshold (например, AnimatorConditionMode.Greater).

Дополнительные ресурсы: AnimatorCondition, AnimatorTransitionBase.AddCondition.

// This script creates a state machine for handling the facial animations of characters in some hypothetical game.
// It demonstrates usage of each AnimatorConditionMode value.
// The character is in a neutral state by default. If their mood is high, they are happy. However, they cannot be happy if they are injured.
// If their mood is low, they are sad. At any state, the character can suddenly yawn or hum.
