Update:
I have now completed the HUD editor and just require a few tweaks in order to marry it up with my calc to conduct the maths to work out how much to shift HUD items by, at the momment I am using a static value of 444 which will change to a variable soon.
Here the user can upload any .res file from any source engine game.
The editor scans the file for all the xpos values and their relevent sections (fieldName's).
Here you can manually select which items you may like to adjust, or simply apply a preset of selected items from the menu, in this case I am using the hudlayout.res file from L4D2. You may also notice that the page states that the HUD will be incremented by 444, this figure will change once I have finished tweaking this to marry it up to the calc, which will in turn define this value after the user enters details into the calc.
Once the items are selected, they are passed to the next page which then scans the file again and edits the selected items by incrementing them by the current test value of 444.
Clicking download presents a "save as" dialog box :)
Essentially the main aim of this tool was to remove all the donkey work of opening up .res files and manually finding and incrementing each of the xpos values, and as such will hopefully make editing of any .res files a lot less time consuming.
One of the added bosnuses is that even .res files from mods are supported although without any selection presets (least at present), for anyone that wishes to use thier fav HUD mod on a multi screen setup :D
EDIT: might help if I provide a link to it eh :P
