How do I stop my screensaver from running in the middle of games?

Wow, I'm almost certain this is perfect for me! But, despite it being free, they still require a valid card number for App Store. I've recently (just hours ago) called in for replacements for all of my cards [due to some possible attempts at fraud] so it will be a few days before I can report back.

Thank you so much for giving me a heads up on this, though. I'll definitely let you know how well it works for me.

Hi,

Thanks for the response. Unfortunately, I already have hotcorners initiated and this method doesn't work due to the game window locking my cursor within it whenever the window is active regardless of whether or not I even tab into the application. It was a good thought. Thanks anyway.

Right, yes, now I just daft for so narrowly missing that. My apologies, I've been a little distracted recently.

I've tested it out and it works perfectly. This is just what I needed. Thank you greatly for checking back and giving me that light wake-up smack.

Edit: This will also help with an unrelated issue of keeping my computer's screensaver on a timer for when I'm streaming media to a separate device. Whenever my screensaver cuts on, I lose the connection for the stream. But, with this, I can set the screensaver to turn back on in several hours to avoid getting out of bed and moving my cursor away from the "disable screensaver" hot corner.
