Forcing 24fps camera frame rate

mtsml

Is there a way to force camera movement to a fixed frame rate (e.g. 24fps) instead of the player's system frame rate? (e.g. 30/60fps etc). I'm trying to emulate the slight stuttering of film pans. Thanks.

You can set Application.targetFrameRate to target a specific FPS, but AC wouldn't be involved.

I created a new object and attached a script to it to limit frame rates. Now frame rates can be set via the UI. How would I go about creating a custom action to change this value via actionlists?

If there's only a fixed number of potential values you'd set it to, you could extent your script with different public functions for each, i.e.:

public void SetTo24 ()
{
    Application.targetFrameRate = 24;
}

Then, attach to an empty GameObject, make that object a prefab, and use the Object: Call event Action to trigger that prefab's SetTo24 etc functions.

Alternatively, it's possible to write a custom Action to replace the script. How many values are you looking to be able to set the frame-rate to?

Just need 24fps and default (e.g. unrestricted).

This is the script I'm using, I attach it to an object and then trigger the function via Object>Call Event using actionlists.

`
public class SetFPS : MonoBehaviour
{
[ContextMenu("Set frame rate to 24")] // Exposes this in the drop-down of Object->Call Event
public void SetTo24()
{
QualitySettings.vSyncCount = 0;
Application.targetFrameRate = 24;
}

[ContextMenu("Set frame rate to Default")] // Exposes this in the drop-down of Object->Call Event
public void SetToDefault()
{
QualitySettings.vSyncCount = 0;
Application.targetFrameRate = -1;
}

}
`

It appears to me working... although when set to 24fps, the onscreen display shows 50fps...so who knows!

`
public class FPSDisplay : MonoBehaviour
{
private float fps;
public TextMeshProUGUI FPSCounterText;

// Start is called before the first frame update
void Start()
{
    InvokeRepeating("GetFPS", 1, 1);
}

void GetFPS()
{
    fps = (int)(1f / Time.unscaledDeltaTime);
    FPSCounterText.text = "FPS: " + fps.ToString();
}

}
