All language subtitles for 7. Displaying frame rates

And this video, we're going to take a look at frames per second.

If we move back over to our game and we switch on our stats, you've actually got the FPS right here.

So it's actually showing you in terms of graphics.

How many frames per second you'll get.

So if I press play at bear in mind in the game, I won't be able to interact with this item.

So if I click and drag on it.

Oh, actually, I can.

Which is interesting, OK.

And I'm getting roughly about 500 frames per second, 400, something like that.

And that's because I'm running on the PC.

Now, if I were to export this now, put it onto a mobile phone, it's going to run around 30 frames

per second, maybe less on some phones.

But I think there's hardly anything at the moment.

So I should imagine it's going to get at least 30 frames per second.

But by default, your phone actually limits your frames per second to 30.

OK.

There is a way to override that.

We can have a target frame rate and get it to run faster than its default so we can get it to run about

60 frames per second instead.

I suppose the mobile phones try and limit it to about 30 frames per second.

So it's not overloading the CPU or the graphics card.

So it doesn't get to point.

All right.

And by going above that 60 feet per second, there is always, you know, the situation whereby the

phone could get really hot.

And he used to call itself down.

So it starts to limit your frames per second.

That's usually when you start to see that dip, when it goes down to like ten frames per second.

Eight five two is simply because the phones to what it's trying to call itself down.

So that's the reason why it's limiting that.

But what we're going to do, we're going to go back into our main, you know, start we're actually

going to set our own frames per second.

So we're going to type application dart set.

Oh, actually, no, sorry, it's not set its target frame rate.

OK, and then I can make that equal sixty.

You can actually set up to anything you want if you want.

It's a thousand frames per second.

You can do that.

I probably would never try that with mobile, to be honest.

If you try and get it to run around the thousand frames per second.

It's pretty good chance it's going to heat up and just instantly kill your frames per second and down

one or two, almost immediately, 60 frames per second is achievable.

Most mobile devices.

So if I press save now and then.

Switch my stats back on and press play.

You will notice these should now come out at about 60.

There we go.

Fifty nine.

It's getting as close as it can to 60.

It's not going above that.

All right.

And now I do have a script.

If I go into assets and into the mobile game resources.

We've got an FPS counter just going to drag this onto the canvas.

This script came directly from the standard assets.

And it's there in order to basically display your frames per second on screen.

Now, I can go back to my simulator, and when I press play in the top left hand corner, you should

see it now display new frames per second.

It's got straight up to 60.

And because this is running by script, it's actually more reliable than the stats element.

It also means that when we're on mobile, we can display enough frames per second as we're playing through

this.

OK, but at the moment, you can see how Metzner constant 60 frames per second.

All we're interested in is mobile, is that we stay above 30 frames per second, if possible.

60 is going to help us to achieve that.
