PlayableBehaviour.PrepareData

Parameters

Description

This function is called during the PrepareData phase of the PlayableGraph.

Note: This method is obsolete and is not invoked by Unity anymore.

PrepareData is called as long as the playable is delayed.

using UnityEngine.Playables;

public class DelayedBehaviour : PlayableBehaviour
{
    public double Delay;
    public float LeadTime;
    private bool m_Started;

    public virtual void OnPrefetchData(Playable playable, FrameData info) {}

    public override void PrepareFrame(Playable playable, FrameData info)
    {
        if (m_Started) return;

        double remainingDelay = Delay - playable.GetTime();

        for (int i = 0; i < playable.GetInputCount(); i++)
        {
            var input = playable.GetInput(i);
            input.SetSpeed(0.0);

            if (LeadTime >= remainingDelay)
                InvokePrefetchData(input, info);
        }

        if (remainingDelay <= 0.0)
        {
            m_Started = true;
            for (int i = 0; i < playable.GetInputCount(); i++)
                playable.GetInput(i).SetSpeed(playable.GetSpeed());
        }
    }
