I'm pretty curious... could anyone explain this function and its parameters?

Quote:

findpathinarray(obj, obj, obj, obj, obj, int, int, int) - returns object - simple pathfinding; parameters are a two-dimensional array ('tiles'):
tiles were we are allowed to walk
tiles where we are not allowed to walk
tiles where we may stop
tiles where we should not stop
start x and y
maximum path length

I have never seen that before. o_O

Umm... Well, I get the syntax and all... But... How do we decide the final destination? Doesn't make sense.

"tiles where we may stop" <-- Those tiles maybe?

If such is true... Then...

PHP Code:


		
			
allowedToWalk = new[level.width][level.height];

notAllowedToWalk = new[level.width][level.height];

allowedToStop = new[level.width][level.height];

tileShouldNotStop = new[level.width][level.height];

tileShouldStop = new[level.width][level.height];

tileShouldStop[ dest.x, dest.y ] = 1;

for ( (every tile in level) as tile)

  {

    allowedToWalk[ tile.x, tile.y ] = !onwall( tile.x, tile.y );

    notAllowedToWalk[ tile.x, tile.y ] = onwall( tile.x, tile.y ); // Eh? Isn't this implicit from the last param?

    tileShouldNotStop[ tile.x, tile.y ] = !tileShouldStop[tile.x, tile.y]; // Implicit?

  }



findpathinarray(allowedToWalk, notAllowedToWalk, tileShouldStop, tileShouldNotStop, IdontKnow, startX, startY, 100);

That would be my best guess at the syntax. Though, I have done zero attempt to confirm this, and there is a Parameter that I am unsure about. ( This is pseudo-code. )
