HELP!!! Blowing objects around

[Sinem]

How can I make the mouse cursor blow objects around? I have several objects I want to be repelled by the mouse when the mouse travels near it. But I want some of the objects to be blown away from a longer distance than others...

How would I go about doing this?

Could somebody please send me a .fla file as I am a beginner in Flash...

thankyou

OooOOOoo a Trig problem most likely. Never done this but I imagine you use
the mouse._x and mouse._y components with the position of what ever object you are moving.

so:

(mouse._x - object._x)^2 + (mouse._y - object._y)^2 = distance_between^2

if (distance_between < some_value) {

*****move object function*****
}


I dont know if mouse._x, mouse._y is correct, didnt actually check. But I think the logic is right.

Hi
This should help.
Have a clip on stage called my_mc then this code on timeline.
Code found here on Flashkit.

code:

---

// Repulsion for a movie clip my_mc from mouse

// user set properties

// how close the mouse needs to be before repulsing the movie clip

my_mc.range = 100;

// the speed at which the clip is repulsed, 100% speed added when the

// mouse is directly over the clip, 0% when the mouse is greater than range

my_mc.speed = 20;

// friction applied to the clip to slow down by when not within range

// the closer to 1, the less friction; 1 is no friction

my_mc.friction = .8;

// internal properties

// the movement of the clip, set and used within onEnterFrame

my_mc.velocity = 0;

// the angle of the clip, set and used within onEnterFrame

my_mc.direction = 0;

// onEnterFrame event controls repulsion

my_mc.onEnterFrame = function() {

	// dx and dy are the differences in distance of

	// the mouse from this clip

	var dx = this._parent._xmouse-this._x;

	var dy = this._parent._ymouse-this._y;

	// pythagorean theorem used to get actual linear distance

	var distance = Math.sqrt(dx*dx+dy*dy);

	// if the distance is less than the range specified

	// the clip will need to be repulsed

	if (distance<this.range) {

		// assign direction to the angle the mouse is from the clip

		// using dx and dy with atan2

		this.direction = Math.atan2(dy, dx);

		// a proximity ratio is created to represent how close the

		// mouse is to the clip; when closer, more speed is applied

		var proximity = 1-distance/this.range;

		// increase velocity by speed factoring in proximity

		this.velocity += this.speed*proximity;

	}

	// here the clip is actually moved based on its velocity using

	// cos and sin to move based on the direction angle (away from mouse)

	this._x -= this.velocity*Math.cos(this.direction);

	this._y -= this.velocity*Math.sin(this.direction);

	// reduce velocity by friction so the clip won't move for infinity

	this.velocity *= this.friction;

};
