get farthest (or minimum distance) visible main screen tile in a given direction?

If you have movement path found

LocalPathFinder pathFinder = new LocalPathFinder(scp.bot);
LinkedList<Position> path = pathFinder.findPath(entity);

you can just check its tiles for visibility from index 0 to 20 for example.

new MainScreenTileDestination(bot, path.get(i)).isVisible()

If you need specific direction, you can ray-trace the line:)

Load region

Add all visible tiles to a list

Grab the biggest or smallest (or a mixture of both if you want a most distant inter-cardinal direction position) x and y coordinates

 

I'm curious what you need this for tongue.png

I'm pretty sure the game map is 16 by 16, so the farthest position to the right would be:

new Position(myPosition.getX() + 16, myPosition().getY(), myPosition().getZ());

Farthest position below:

new Position(myPosition().getX(), myPosition().getY() - 16, myPosition().getZ());

etc...

 

 

Oh hey, perfect, this is exactly what I need QwPha8E.png For some reason I overlooked this, thinking I'd need something more complex.

Are you doing barrows tunnel traversal without a path finding algo ? huh.png

 

 

 

I originally tried using a simple A*-type algorithm, but I encountered the problem of rooms being too far to load. Because of this, there's no way to determine a path unless you're already in the center of the catacombs, making it pretty much useless :P 

 

So my solution is this: 

 

(for data I have an enum that stores room areas, as well as Point[]s that possible doors reside at)

  • analyze current room's number of openable doors
  • if viable doors < 2, that means there's only one possible path; follow that path to the next room
  • if viable doors = 2, there's two paths. If one of the paths leads to the previous room, forget it and use the other path. if said other path leads to a blacklisted door, blacklist the current room as well.
  • if viable doors > 2, prioritize in this order: 1) doors that lead to the chest 2) doors that lead to short tunnels 3) whatever is left (doors that lead to long tunnels)
  • if a room has only 1 door and it's not the ladder room or chest room, blacklist it

 

It works pretty okay so far  :D

You could just go to the center once and store all the required data once in a class though (as you would do for a webwalker).

If it works then that's all that matters I guess x)

Actually, I tried. the problem is that every time you spawn a new tunnel path (every chest run at barrows), you'd have to be able to check whether each door on a given path is openable. When I tried doing this via getActions.contains("Open"), unloaded doors return true whether they're actually openable or not, meaning it couldn't determine a path, since A* (and pathfinding in general afaik) obtains its path from the end point to the beginning.

You can get the openable doors via config(s) tho, without having the doors loaded.
