Astrolabe ยป Astrolabe/API ComputeDistance
Takes two sets of coordinates and computes the distance between them in game yards.
dist, xDelta, yDelta = Astrolabe:ComputeDistance( c1, z1, x1, y1, c2, z2, x2, y2 )
[edit]
Arguments
- c1, z1, x1, y1
- World Map Point - point 1
- c2, z2, x2, y2
- World Map Point - point 2
[edit]
Returns
- dist
- Number - the absolute distance between the two points in game yards
- xDelta
- Number - the East/West distance from point 1 to point 2 in game yards
- yDelta
- Number - the North/South distance from point 1 to point 2 in game yards
[edit]
Details
Specifically, the calculation is (point 2) - (point 1), so adding the xDelta and yDelta information to the first point would get you to the second point. Note that all distances follow the World Map API convention of using TOPLEFT as the 0,0 point.
This function returns nil for all arguments if trying to compute a distance between the two specified points is meaningless. (IE. one point is on Azeroth and the other is in Outland)
