RADAR DOES NOT APPEAR INSIDE

[zRiaan]

I have a problem with the radar and I do not know how to solve it, with the radar activated, I go into some interior and the radar, hud does not work, could you help me?

There was a misplaced 'end' at the end of blips section instead of being at the end of map-render section. The above code is corrected, and I've included comments regarding where the error was, marked by -- //// comment //// to distinguish it from the original comments.

The code will not render the map when inside an interior. If you prefer the map to be rendered at any time, regardless of interior world, set the variable alwaysRenderMap to true.

P.S. Next time, when including any code, use [­code­] markup as it's easier to read.
