Does anyone know/has anyone used a method that checks whether a GroundItem is reachable or not?

For example clicking something that's on the other side of a closed door should say "I can't reach that!" does anybody know a method that recognises the player cannot reach the item?

 

Thanks in advance!

GroundItem g = groundItems.closest("bobrocket is a nub");
if (g != null && g.exists() && map.canReach(g)) {
    //blah
}

apa

GroundItem g = groundItems.closest("bobrocket is a nub");
if (g != null && g.exists() && map.canReach(g)) {
    //blah
}

apa

 

 map.canReach() just what I was looking for, thanks!!

GroundItem g = groundItems.closest("bobrocket is a nub");
if (g != null && g.exists() && map.canReach(g)) {
    //blah
}
