Hi!
so basically, i aint very good at scripting, so what i really need is some of you guys to help me with some stuff! i already got locked doors with keys and such... i looked that up on the wiki i also got how to make level doors and enemies spawn and follow a path... there are some other stuff that i think i know too... but i really need help to make a note! because i think there is something wrong with my .lang file... in the start i only had the name and description for my key, and then i make the note... and when get into the game, both the items appear blank... but when i remove the code for the note... they key works again...
i also need to know how to make scary noises like footsteps and such...
please respond!
thanks
