i make that
in instance variable of this sprite called 'lerpA' and 'lerpB +150'
on start of layout> set to lerpA to self.x so on started 'lerpA' store sprite position x
on start of layout> set to lerpB to self.leppA+150 so on started 'lerpB' store sprite position x +150
now when instance 'variableA' is 1
lerp(self.lerpA, self.lerpB, 0.1)
i expect this lerp should move position x 150 forward even if i change sprite position
anywhere on layout
