bool UI_is_dest_reachable(actor npc, int pos[])
bool npc->is_dest_reachable(int pos[])
Checks if a NPC can walk from its present location to a specified position.
Parameters
| Parameter / value | Description |
|---|---|
npc |
The NPC we wish to check. |
pos |
Destination [x, y] or [x, y, z]. With two elements, z defaults to zero. |
Return
true if the NPC can walk to the supplied destination, false otherwise.
Invalid NPCs, positions with fewer than two elements, and negative z values return false. The path test accepts reaching within one tile of the destination; it does not require occupying that exact tile. SI beta also has UI_sib_is_dest_reachable(pos, npc), with the arguments reversed.
