Calculating distance (example)[edit source]
Calculating distance travelled with the Pythagorean theorem, using sqrt and pow:
Event OnEffectStart(Actor akTarget, Actor akCaster)
target = akTarget
coords = new float[6] ; let's not declare 6 separate vars
coords[0] = target.X ; X = hardcoded short for GetPositionX(), same for other axes
coords[1] = target.Y
coords[2] = target.Z
RegisterForSingleUpdate(5)
EndEvent
Event OnUpdate()
coords[3] = target.X
coords[4] = target.Y
coords[5] = target.Z
; Pythagorean theorem for 3D planes: sqrt((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)
float fDist = Math.sqrt(Math.pow((coords[3] - coords[0]), 2) + Math.pow((coords[4] - coords[1]), 2) + Math.pow((coords[5] - coords[2]), 2))
Debug.trace("Travelled " + fDist + " units.")
EndEvent
