Hmm, the script does look correct at first glance.

No crashes? No warnings in the log?

If you enable debug environment, you might get a warning message if it cannot find a certain something.
Also double check that all names are correct and no typos.

One thing you can change is to set 30 to 30.0f instead (as it's a float value).

I don't get any warnings ingame and no crashes. I'll look in YouTube how to open debug mode, still if you think it's hard to do, can you tell me how to? You don't have to answer for the debug, I might learn it myself via another video.
