Since the health is a float, yeah, it can create issues. A health of 0.000000001 will sill be greater than zero, but that would almost assuredly be displayed to the user as simply 0. The easiest solution is to have health and damage always be integers. A less great solution is to use a non-floating point decimal format. If such doesn’t exist in your language, you can emulate one by having health and damage both always be integers, but move the decimal point over, say two points, when displaying it to the user.
I asked this question on this post on a different instance, but would there be issues being that the code compares a float to integer zero “0”?
