Hello!
I've just seen the moveObjects function, and I was thinking of adding it to the Map Editor:
With a GUI that have these 'options':
"Open when player/vehicle is at [(Example)10] meter(s)"
"Set Closed Point" and "Set Opened Point"
"Time to move [(Example)3] second(s)"
And then, after you saved your map, it'll insert the line code to the map's file!
