Get distance between 2 arbitrary tiles

[Aeglen 328]

Hi, I've been trying to get the walking distance/penalty between a bunch of places (outside of loaded distance, in other floors, etc) but the following method does not work:

getWalking().getWebPathFinder().getMovementCost(sx, sy, ex, ey, z);

It gives:

• [ERROR]17:21:14: Exception has occurred while running! Please report error to developer if problem persists: java.lang.NullPointerException at org.dreambot.api.methods.walking.pathfinding.impl.PathFinder.getMovementCost(PathFinder.java:195) at NWalk.execute(NWalk.java:46) at org.dreambot.api.script.impl.TaskScript.onLoop(TaskScript.java:84) at org.dreambot.api.script.AbstractScript.run(AbstractScript.java:264) at java.lang.Thread.run(Unknown Source)

I also find it curious that there are 5 arguments as opposed to 6 (z could be sz and ez) and that it takes ints rather than Tiles. Is there a way to do this without presumably getting the movement paths and iterating through them?

Note: (sz, sy, z) and (ex, ey, z) were valid tiles at accessible points on the map when tested.

EDIT: Yeah iterating through the movement path works well enough for my purposes.

tileOne.distance(tileTwo);

It's the "walking" distance I'm interested in, not as the crow flies. Iterating through the WebNode path solves this problem well enough. However, it would still be nice to have a way to figure out whether the next step is something like Stairs or just another click on the map.
