Animator.StringToHash

Parameters

Returns

int The hash of the input string.

Description

Generates a parameter id from a string.

This method uses CRC32 to generate an id from a string. Use a generated id to optimize assigning and retrieving parameters. A generated id is valid as long as the input string doesn't change. This means that a generated id persists between sessions and can be used for networking.

    // The Animator component on the GameObject this script is attached to.

    // Cache the hash of the bounce state.
    int m_BounceStateHash;

        m_Animator = GetComponent<Animator>();
        m_BounceStateHash = Animator.StringToHash("Base Layer.Bounce");

        {
            // Play Bounce but start at a quarter of the way through
            m_Animator.Play(m_BounceStateHash, 0, 0.25f);
        }
