The prompt works fine, so when the prompt is triggered, the prompt action text will change to open and viseversa, it is just the tween that is not working It doesn’t fire.
Well,
I tested it with the base part itself [the main door part] and it worked, there’s possibly an issue with your Hinge ,because the rest of the code looks fine
My parts were anchored, and worked fine, so I don’t think it has to do something with that.
Is the hinge your main part?
Also, since your tween doesnt play, there is apparently an issue with the tween[ maybe the tables you set], try to see if theres any error with the tables inside the tweens[print,warn ,etc] - debugging.
