fade question

[aiaf]

  context->SetColor(0.0, 0.0, 0.0, alphaInitial);
  context->DrawRect(0, 0, context->GetWidth(), context->GetHeight());
 
  if (alphaInitial > 0.1) {
    alphaInitial = alphaInitial - 0.005;
  }

I need another way of doing this fade that is not dependent on machine speed,

Want this fade to take 3 seconds no matter the machine is running on.

Any idea how to do this ?

Multiply by Time::GetSpeed().

Thanks

alphaInitial = alphaInitial - (0.003 * Time::GetSpeed());

I leave it here in case someone need in future.

Here are some values of the Time::GetSpeed() on my machine:

1
20.36
11.74
9.59
6.295
4.6775
3.80875
3.43438
3.21719
3.07859
3.0693
3.00465
3.12232
3.21116
3.07558
3.06779

You can also do this:

fadeouttime = Time::GetCurrent() + 3000;

And then this:

float alpha = 1.0f - float(fadeouttime - Time::GetCurrent()) / 3000.0f;
