actionscript 3 - Move and Scale a MovieClip smoothly between multiple points -

i have set-up of 3 horizontal rows button aligned each of them , character (centered each row) want move between these rows (think of little big planet). able program character moves between 3 rows , has set scale when does, want see character moving between points; not watch teleport location. i've tried can think of: loops, boolean on/off, velocity/distance/difference shenanigans, etc., i'm having no success getting move @ button click , continue moving until reaches point. i'm not sure if can set-up scale incrementally until reaches desired end scale size or not. saw similar problem asked on site, solution gave uses point class , lot of math, , have never had success getting flash use points. suggestions appreciated.

sounds you'd simple. suggest using tweening library. prolific of greensocks tweenlite, part of animation platform

using tweenlite, following:

in place of:

player.y += 100; 

you do:

tweenlite.to(player, 1,{y: player.y + 100, ease: quad.easeinout}); 

this tween (move gradually on time) player object it's current position specified y (player.y + 100). on 1 second , nice in , out ease.

you can add more properties tween (scalex/y, x) really.

do note, there many tweening platform alternatives, including 1 baked flash professional. tweenlite not free use if charge end users fee application. sure review license if use commercially.
