How to Use This Calculator
  1. Enter Start X, Start Y, and End X.
  2. Set End Y and Arc Height.
  3. Review the Arc Length (px) result.
  4. Use Straight Distance (px) and Speed (px/frame @24fps) to inform your decision.

What each input means

Start X
X coordinate of the start position.
Start Y
Y coordinate of the start position.
End X
X coordinate of the end position.
End Y
Y coordinate of the end position.
Arc Height
Height of the arc above the straight-line path (0 for straight).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Start X = 100, Start Y = 500, End X = 700, End Y = 500 = 5 input(s) provided
  2. Calculate Arc Length
    721.11 = 721.11
  3. Calculate Straight Distance
    Straight Distance
    600 = 600
  4. Calculate Speed
    Speed
    30.05 = 30.05
