Well , This System is now currently being used by a famous CnR Server and it has been very popular and many have requested this type of Gps System. i had made/scripted this for my server, so if any bugs has been found i will be fixing it.

Its designed currently with cordinate command. you can enter a cordinate by using command /findpath (x,y,z) and the arrows will appear on roads and you will have to just follow it and it will till there you reached your destination node. this System required Modern Gps Plugin. the system also detects if there is a route change. its also easy to just add new cordinates to it.

new vpaintjob[MAX_VEHICLES] = {3, ...};
new vcompids[MAX_VEHICLES][MAX_COMPONENT_TYPES];

vpaintjob[vehicleid-1] = 3;

for (new c = 0; c < MAX_COMPONENT_TYPES; c++)
{
	vcompids[vehicleid-1][c] = 0;
}

- Fixed small errors.
- Code optimizations.
*ADDED* File based language system allows you to add new languages without hard coding it!
*ADDED* Editor compact mode that creates a smaller editor interface that you can move in the X and Y coordinates!
*ADDED* File base template system allows you to add new templates in different languages within a single file!
*ADDED* Feature to change the layer of a Textdraw.
*ADDED* Manual value change using the ALT key while changing values.
*REMOVED* Polish TXD buttons.
*REMOVED* Update check due to non existence domain.
*IMPROVED* Dialog page change with now both "Next" and "Back" button.
*IMPROVED* Small changes in the interface colors and style.
*IMRPOVED* New Splash Screen/Welcome Screen.
*IMPROVED* Changed from simple for-loops to much faster foreach-loops for projects, textdraws, languages and templates.
*IMPROVED* Custom color changing dialog now allows you to insert both HEX and RGBA values.
*IMPROVED* Editor interface is now always on top of everything.

*ADDED* Player Progress Bar (By Southclaws) support.
*ADDED* "Player Progress Bar" template in "templates.xml"
*FIXED* Deleting a TextDraw wasn't deleted from the iterator so it was been saved anyways.
*FIXED* Callback OnPlayerDisconnect had a missing parameter in code and while project export.
*FIXED* A bug with the list item recognition in "ndialog-pages.inc" and the NTD itself.
*IMPROVED* Editor Buttons are now disabled when a textdraw isn't supporting a feature.
*IMPROVED* Default TextDraw name is now categorized according to the type.
*IMPROVED* Changed the "Preview Model" button to "TextDraw Settings".
*IMPROVED* Directory names are now lower case for use in linux OS.
- Changes in all language files (New dialog and messages).
- Code has been "Const-corrected" for use in the Zeex Compiler.
- Code optimization.
- Fixed other small bugs.
