Well I want to know how to do script if I want to do mixure ( or mixture Im not sure ) of three potions like I put one in the burner then the other one to it and it will make other one potion and script like this ... I really need help with this and second thing I need help with is how I have to set player look at because I do the script and the player doesnt look at the thing even the whole script is ok I mean that it plays sound etc etc but player doesnt look at the thing ( In this case its helmet ) well and third is how can I name level doors like If i look at them and I want to interact with them it will show something like "Storage" and when I click on it it will say something like "Locked and I need to find key" Well thats all I really need help with it ...
