param($key) # Any OnKey_ script is passed the key press as a parameter. # If you don't ignore either key up or key down, it will behave unexpectedly. # If you want the key to respond to being held down, you'll want to ignore KeyUp if (-not $key.KeyDown) { return } # (which we do here) if ($Player) { # If there was a player on the screen $Player | # Move it UP # (this works by piping the current player in, and using a [ScriptBlock] to alter the value for Y) Move-Sprite -Y { $_.Y -1 } } |
