showap is more of something from classic, it's not new it's been around for quite a while now, ap isn't really the thing for Ol' West as it's eating food and basing with guns. Not swords. Which of-course classic is.

It's more of like a health system. If you click on your profile, you'll see a number/50 this is your health. So, if you say you were 100ap. You'd look like this:
"SammyPs" (In a yellow golden font color/colour).

If your ap was to be 50? Which is a average, your still a-live health, let's just say 50 for ol' west is 25. As the maximum health limit is 50. It will look like this:
"SammyPs" (Smooth white font color/colour).

And of-course, if you're at 0, you would be on the ground.. well.. dead.

This all sums up to showap showing your health.
