Actionscript 2 to 3. please help!

1

hey,

i have just started studying actionscript 3 at college and need some help migrating some script from 2 to 3. any help would be greatly appreciated:

ryu_mc.step=15;
ryu_mc.attack = false;
ryu_mc.stance= 1;
ryu_mc.crouch=false;

this.onEnterFrame = function()
{
if(ryu_mc.attack==false)
{
if (Key.isDown (Key.RIGHT) )
{
ryu_mc._xscale = 100;
ryu_mc.stance=1;
ryu_mc._x+=ryu_mc.step;
ryu_mc.gotoAndStop(“walking”);
}
else if (Key.isDown (Key.LEFT) )
{
ryu_mc._xscale = -100;
ryu_mc.stance=0;
ryu_mc._x-=ryu_mc.step;
ryu_mc.gotoAndStop(“walking”);
}
}
}

it is simply script in AS2 to make a character move left and right on the key getting pressed. any help migrating this to AS3 would be appreciated.

thanks

My advice would be searching Google, for action script tutorials in your native language. Also maybe learning more English would help you, as there are lots of tutorials in English.
