Lol, this is a long script.

So anyways, i have made a punch script that deals knockback and does diffrent things if difrrent keys are pressed together.

I am integrating sound, where if the punch makes no contact, it plays "Sound1" and if contact is made, it plays "sound2"

So, there is nothing wrong with the sounds themselves, rather the way the script determines what sound to play.

I have a variable called "succ" that does this job. (BTW it means succsess, not, you know)

At the beggining, it is set to "0" (no contact), then if it makes contact, it is set to "1", (contact). Then at the end of the script, it determines what sound to play.

For some reason, it always plays 0, even when contct is made. I know there is no problem defining the variable, because when i remove the line of code that sets the variable to 0, it will play sound2, but then it won't play sound1 (obviously). And i put a print to print what succ was right after succ was told to be 1, and it did become 1. it just magically becomes 0.

I can't figure out whats wrong.

Thanks in advance.

(BTW i put comments next to things that are important to this question. Comment if more information is needed)
