Due to the recent help topic stating a Add-on maker exsisted. (Which I doubt btw) I find this would be a good idea.
It would be a program separate from blockland, and how it would work is you just assemble a bunch of pieces together to get your result.
Kinda like Dreamweaver or our friendly event system. You just drag certain components, such as projectile properties, or weapon firerates, or tool functions and set certain values for each. And boom. Press a key and it creates a script for the weapon. The only thing you need to do is model the weapon. (or bribe a friend).
Seems like a good thing to me, and considering it doesn't have to run on tourqescript, it seems very possible.
