| Reinforcements:
I've tried, I didn't get it to work. |
| Headcrab Zombie:
if(%string $= "") ? |
| Penguin/Person:
Why would it have nothing as in the variable hasn't been assigned to anything or nothing as in the variable = 0? |
| Headcrab Zombie:
I'm not sure I understood what you just said. If it's a string, you have to use $= "" if you just use == 0 it will always be true because trying to convert a string to a number will always be 0 |
