Weird shaking that occurs...

[TaroNuke]

Whenever I zoom in or out using _root._xscale,
my character shakes up and down ever so slightly.
I am using a while loop that makes the character's _y -= 0.1 if character is touching ground,
but it's really weird because everything works just fine without zoom.
It is the kind of game in which the camera often needs to zoom in or out.

What happen? Did somebody set me up the glitch?

this is one of flash's little idiosynchracies. It has to do with how the Vectors are re-drawn. Since it is redrawing everything at the different zoom levels sometimes you will see "jittering" and sometimes not. my guess is that your character is falling through the terrain for a split second before the code corrects this. and at some zoom levels you can see this occurring. you could post your terrain code here for us to have a look at if you want.

this isn't surefire but you could try bitmapCacheing your character sprite, this will eliminate some of the evidence of redrawing in some cases.

this.cacheAsBitmap = true

this.cacheAsBitmap = true

Never heard of this sentence... how it works??

PROBLEM SOLVED.

I Math.round()ed the _root._x and _root._y co ordinates. No more shaking.
