<# .SYNOPSIS Sets the Turtle's position .DESCRIPTION Sets the position of the Turtle and updates its minimum and maximum. This should really not be done directly - the position should be updated as the Turtle moves. .NOTES Changing the position outside of the turtle will probably not work how you would expect. #> param([double[]]$xy) # break apart the components $x, $y = $xy # and add a position if we do not have one. if (-not $this.'.Position') { $this | Add-Member -MemberType NoteProperty -Force -Name '.Position' -Value ([Numerics.Vector2]@{ X = 0; Y = 0 }) } # Modify the position without creating a new object $this.'.Position'.X += $x $this.'.Position'.Y += $y # And readback our new position $posX, $posY = $this.'.Position'.X, $this.'.Position'.Y # If we have no .Minimum if (-not $this.'.Minimum') { # create one. $this | Add-Member -MemberType NoteProperty -Force -Name '.Minimum' -Value ([Numerics.Vector2]@{ X = 0; Y = 0 }) } # Then check if we need to update our minimum point. if ($posX -lt $this.'.Minimum'.X) { $this.'.Minimum'.X = $posX } if ($posY -lt $this.'.Minimum'.Y) { $this.'.Minimum'.Y = $posY } # If we have no .Maximum if (-not $this.'.Maximum') { # create one. $this | Add-Member -MemberType NoteProperty -Force -Name '.Maximum' -Value ([Numerics.Vector2]@{ X = 0; Y = 0 }) } # Then update our maximum point if ($posX -gt $this.'.Maximum'.X) { $this.'.Maximum'.X = $posX } if ($posY -gt $this.'.Maximum'.Y) { $this.'.Maximum'.Y = $posY } |
