You are correct about it allowing you to have zero health and not die, but whether or not that’s the correct behavior will depend on the game. Off the top of my head I know that Street Fighter, some versions at least, let you cling to life at zero.
I know this is /c/Progammerhumor, but I wanted to pull on this thread a little bit for my own edification. I’m a Python guy and have been a while, but I’ve dabbled in other languages. The screenshot says “MonoBehaviour” which makes me assume this is mono or a .Net-like language (you know what happens when you assume).
If your player health is a float, would mono or .Net have an issue comparing the float with integer zero “0”? I mean, it seems like floating point precision may make it impossible for it to ever “equal” integer zero, but it also seems like the code isn’t accounting for that precision error.
Floating point errors are a product of how floating points work as a mathematical concept. So they’re independent of the programming language and can happen everywhere.
In this case though, I doubt it’s a critical issue. So the player “died” when they actually had 0.000000000027 hp left or whatever. Who cares? Do you need to be that precise?
This won’t work if you can ever take more than 1 damage. If you were at 1 and received 2 damage you would become invincible. You’d want to do less than or equal to.
Should it be
?
Otherwise the player could have 0 health and not die? I’m sleep deprived so forgive me if I’m wrong
You are correct.
Counting this meme as my first FOSS contribution
Holy shit I was there with you sir! With the zeros and stuff
Open up ticket first, please. Thanks Codemonkey.

Am I overthinking this?

Hanging on with 1.70E-31 health.
