So I have been messing with the construction set and wanted to have a personal lantern that wont be destroyed when submerged in water if it requires a script does anybody know the program for that?

I don't think you'd need a script.

Open the CS and select a latern, or create your own with textures/meshes, and open the details tab, if I recall correctly, there's an "Ignores Water" checkbox.

ok ill look for something like that.

so Im not seeing a ignore checkbox

There is already mod that does this. http://mw.modhistory.com/download-55-3779 it is. It is also part of my http://www.gamesas.com/topic/1574348-relz-dwemer-legacy-resourceplayable-plugin/ mod.
