Obtaining map grid reference (eg: Fg52)

[dr_eyeball 16]

How do you obtain the map grid reference (eg: Fg52) for a given position, or the position reference displayed on your GPS?

Is there a command for it or do you have to calculate it yourself?

Edit: Thanks for the code, Wolfrug.

Open notepad, copy-paste the "code" section this into it, save as something like 'gridRcoord.sqf'. Call by initing a unit. From readme :

(Also available with demo mission from OFPEC - alas these forums don't allow attachements!

Quote[/b] ]HOW TO USE IT:

Either check out the demo-mission on Rahmadi, included in this zip and find out how to implement it or use the following lines.

Use these lines to get the function to work:

fAdd = compile loadFile "getRCoord.sqf"; --> to compile the function and attach a name

hint format ["%1",[soldier] call fAdd]; --> shows a hint with the grid coordinates

or

titleText [format ["%1",[soldier] call fAdd],"PLAIN",1]; --> shows a titleText with the grid coordinates

Or any other use you can give to the function output. Just remember to use the first line to compile and load the function.

Good luck.
