hey i'v made 'Vashta Nerada' & 'Sontaran' skins if u want them. if u wanna see them let me know by mailing me =). also u should add Jenny (the Doctors daughter) as a companion, & that u get her on messaline.
The problem is is that when an item is used you get an I, J, K input value (x,y,z) of what it's looking at but when you are too far away to reach those values say you are looking at nothing or the air block or what not. I tried implementing it "if that block is a lever and you use the screwdriver turn it on" the thing is you just click it like its a normal button or lever.
It's also kinda similar problem with the door when trying to use the item it does the block on click instead which would come back as false sense you can't open iron doors.
you could make it so when you are holding the sonic screwdriver you have a longer reach then when you aren't eh ehhh
