The applet will be able to run on a webpage, this way you can use it regardless of your OS.
Pretty much all you do is select what you want to add, eg. Door, window, cupboard, etc. then just type in the stuff it needs to know; X, Y, view, loop, new.room, flag number.
Then the applet has two output text boxes;
One to put in the start of your Logic (just under "if (isset(f5)){") and the other to paste into your code( before the last "}" ).
The applet will output the code for all the things you need; opening the door, not close enough, going into next room, coming back out of the room, knocking or locking doors, objects in drawers. Any other ideas i will look into as well.
I've already done most of the doors part so far, but could take a while with the rest of it, as I'm doing the programming in Notepad.
