Slope Detection
(160 posts) (31 voices)-
here i will show you all y it isn't working hopefully one of you can help me cuz i cant think at the moment
one of the balls goes to far on the big slopes and so it screws up the rotation

I think that's the same technique I use...
Do you calculate the angle between the 2 balls and rotate the line according to that?
I'm still trying to write a code that the 2 balls stay on the same distance towards eachother, that should fix some problems.Not in cruelty

Nyubis, you're figuring out a constant distance script?
Look here, there's a bit on constance distance: http://www.emanueleferonato.com/2007/08/26/creation-of-a-ragdoll-with-flash-part-2-constraints/
Also, I'm currently in the process of fine-tuning my slope detection

I did very much like the example in the kirupa thread in the author's post that he was troubled with, it used slope detection but unfortunately he provided no source, so I guess I won't find out.
I say:
What thread?? Link?? I am doing the same thing on KF and need some help

1. create a rectangle with a curved in top (large)
2. create a square (small)
3. convert to movie clips- give instance names: rectangle = slope, square = player
4. set the square's registration to middle bottom
5. apply this code to first frame on root level:player.onEnterFrame = function() { back = player._y; front = player._y; center = player._y; while (slope.hitTest(player._x-20, back, true)) { back -= 1; } while (!slope.hitTest(player._x-20, back-1, true)) { back += 1; } while (slope.hitTest(player._x+20, front, true)) { front -= 1; } while (!slope.hitTest(player._x+20, front+1, true)) { front += 1; } while (slope.hitTest(player._x, center, true)) { center -= 1; } while (!slope.hitTest(player._x, center+1, true)) { center += 1; } player._y = center; player._rotation = Math.atan2(front-back, 40)*180/Math.PI; if (player._x<500) { if (Key.isDown(Key.RIGHT)) { player._x += 3; } } if (player._x>0) { if (Key.isDown(Key.LEFT)) { player._x -= 3; } } };yoPosted 4 years ago # -
That's where I learned it. It's a great tutorial.
Just got back on the internet after losing my access for a week. Read more on Random Discussion.Posted 3 years ago # -
Thanks! It works, but it's a bit jerky. Here's my code:
var r:Boolean = false;
var l:Boolean = false;
var jumping:Number = 0;
var jumpingd:Boolean = false;
var falling:Boolean = false;
var walkSpeed:Number = 3;
var jumpSpeed:Number = 10;
var fallSpeed:Number = 0;
var xspeed:Number = 1
var yspeed:Number = 0;
var gravity:Number = .5;
var dir:Number = 1;ground.visible = false;
stage.addEventListener(Event.ENTER_FRAME, movement1);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keysDown);
stage.addEventListener(KeyboardEvent.KEY_UP, keysUp);function keysDown(event:KeyboardEvent) {
if (event.keyCode==Keyboard.SPACE) {
jumpingd = true;
}
if (event.keyCode==Keyboard.RIGHT) {
r=true;
}
if (event.keyCode==Keyboard.LEFT) {
l=true;
}
}function keysUp(event:KeyboardEvent) {
if (event.keyCode==Keyboard.SPACE) {
jumpingd = false;
}
if (event.keyCode==Keyboard.RIGHT) {
r=false;
}
if (event.keyCode==Keyboard.LEFT) {
l=false;
}
}function movement1(event:Event) {
if((jumpingd==true) && (!jumping)) {
yspeed = -12;
jumping = 1;
}
yspeed += gravity;
while(ground.hitTestPoint(char.x, char.y + char.height/2, true)) {
char.y--;
yspeed = 0;
jumping = 0;
}
if ((!ground.hitTestPoint(char.x, char.y+char.height/2+1, true)) || (yspeed<0)) {
char.y += yspeed;
} else {
yspeed = 0;
jumping = 0;
}
if (r==true) {
char.x+=walkSpeed;
dir=1;
}
if (l==true) {
char.x-=walkSpeed;
dir=-1;
}
var back:Number = char.y;
var front:Number = char.y;
var center:Number = char.y;
while (ground.hitTestPoint(char.x-20, back, true)) {
back -= 1;
}
while (!ground.hitTestPoint(char.x-20, back-1, true)) {
back += 1;
}
while (ground.hitTestPoint(char.x+20, front, true)) {
front -= 1;
}
while (!ground.hitTestPoint(char.x+20, front+1, true)) {
front += 1;
}
//while (slope.hitTest(player._x, center, true)) {
//center -= 1;
//}
//while (!slope.hitTest(player._x, center+1, true)) {
//center += 1;
//}
//player._y = center;
char.rotation = Math.atan2(front-back, 40)*180/Math.PI;}
Do you know how it could get less jerky, or just how to make the char jump in the angle that he's at?
EDIT: To jump at the angle, I think you'd need something like:
char.y += Math.sin(char.rotation * Math.PI/180) * yspeed;
char.x += Math.cos(char.rotation * Math.PI/180) * walkSpeed;But, I don't know where it would go...
Any help?

Oh, you mean this post?

I found that, but I still couldn't convert it to as3. Here's the code (It's inside the character):
onClipEvent (load) {
this.dir = 1;
function updateBB () {
while (!_root.ground.hitTest (_root.bb._x, _root.bb._y, true)) {
_root.bb._y++;
}
while (_root.ground.hitTest (_root.bb._x, _root.bb._y, true)) {
_root.bb._y--;
}
}
}
onClipEvent (enterFrame) {
if (Key.isDown (Key.RIGHT)) {
this._x += 10;
this.dir = 1;
}
if (Key.isDown (Key.LEFT)) {
this._x -= 10;
this.dir = -1;
}
while (!_root.ground.hitTest (this._x, this._y, true)) {
this._y += 5;
}
while (_root.ground.hitTest (this._x, this._y, true)) {
this._y--;
}
_root.bb._x = this._x + (20 * this.dir);
_root.bb._y = this._y;
updateBB ();
rot1 = Math.atan2 (_root.bb._y - this._y, _root.bb._x - this._x);
this._rotation = rot1 * 180 / Math.PI;
if (this.dir == -1) {
this._rotation += 180;
}
updateBB ();
}I couldn't port it to as3, though... Can any of you?

nice guys! and if you want to get a smoother rotation changelization
instead of just saying this._rotation=(wanted rotation)
dovariable1=(wanted rotation)-this._rotation;
this._rotation+=1/5*variable1;The only reason I don't have a Nobel Prize is because I'm too much of a genius for the common mind to grasp.Posted 3 years ago # -

do
variable1=(wanted rotation)-this._rotation;
this._rotation+=1/5*variable1;example:

(spoof of fpa, its called, the Fancy Shorts Adventure)
p.s. i'll work on a code for more than 90 degree rotation.
