math.random.whats wrong with my code?!!

[joe dc]

Why is it doing this??

What I want is for my mc to slide to a new random x position when it is less
than 5 pixels away from its target, it keeps doing this. the problem is for
some bloody &*?$(()** reason my random numbers only keep going up!! why is
this?? i want to produce random numbers between 1 and 770 - this is my code..

Please somebody help me please..


onClipEvent (enterFrame) {
_root.xdif = _root.targetx-this._x;
if (_root.xdif<5) {
_root.targetx = Math.floor(Math.random()*(770))+1;
}
if (_root.xdif<5) {
this._x = null;
} else {
this._x += (_root.xdif/50);
}
}

Because you have put "if (_root.xdif<5)", this will always be the case for
negative numbers ie/when targetX is less than _x.
try something like this
onClipEvent (enterFrame) {
_root.xdif = _root.targetx-this._x;
this._x += (_root.xdif/50);
if (Math.abs(_root.xdif)<5) {
this._x = _root.targetX;
_root.targetx = Math.floor(Math.random()*(770))+1;
}
}
