my last topic didnt go well but any way
is there a way to make an object move "forward" as in not in _x because if i am on a slope my over all speed increases but my _x speed doesn't making it look odd. i have the rotation but is there a link between rotation and direction?
thanks
moving 'forward'?

I was wondering the same thing! It seems like there should be a way... Maybe someone else knows.

Could you use some math to take the angle of the character and just subtract that from the character's xspeed? Something like
slowdown = angle/10;
if (Math.abs(xspeed)-slowdown > 0) { xspeed -= slowdown; }Note: I just pulled that out of my brain, I don't know if it would actually work the way you want it to.

I recommend that you learn some stuff about basic vector math/trig. Look up projection and components of vectors which should explain why the script works.
Basically what the script does is take a movement speed (vector) facing at an angle (like your character's rotation), then splits it into an x component and a y component.
This sort of math is really helpful in games.

moveRL = speed * Math.sin((_rotation)*(Math.PI/180))
moveUD = -speed * Math.cos((_rotation)*(Math.PI/180))Is what I have in my 'cache' fla...
Well, in FPA, it's set up something like:
this._x += this.RLx(this.moveRL)
this._y += this.RLy(this.moveRL)With the functions:
RLx = function(ex) { return (ex*(Math.cos((this._rotation)*(Math.PI/180)))) }
RLy = function(ey) { return (ey*(Math.sin((this._rotation)*(Math.PI/180)))) }When you're jumping, moveUD controls up and down motion, while moveRL controls only movement on the x axis, when you're on the ground, moveRL controls speed along the ground.

Click samples at the top, then the ActionScript 2.0 samples. Check out 'thrust movement.' That was some of the first code I ever learned, actually, heh.
