Bouncing Ball Tutorial, SwishMax - Beginner Options

[fudoki]

[color=#669900]the script for the ball in my sig, i was not the original creator of the ball script although i learnt from it and tweaked it, so this should not be used for commercial use. That said here is the script for the ball in my sig.

create a circle and give it this script

on (press) {
startDragUnlocked();
dragging = true;
}
on (release,releaseOutside) {
stopDrag();
dragging = false;
}

then group the circle as a sprite and give the sprite this script

onFrame (1) {
_x=0;
_y=0;
xspeed=Math.random()*60-30;
yspeed=Math.random()*60-30;
rightedge=300;
leftedge=0;
topedge=0;
bottomedge=40;
gravity=1;
drag=.98;
bounce=.9;
}
onFrame (2) {
if (!dragging) {
_x = _x+xspeed;
if (_x+_width/2>rightedge) {
_x = rightedge-_width/2;
xspeed = -xspeed*bounce;
}
if (_x-_width/2_x = leftedge+_width/2;
xspeed = -xspeed*bounce;
}
_y = _y+yspeed;
if (_y+_height/2>bottomedge) {
_y = bottomedge-_height/2;
yspeed = -yspeed*bounce;
}
if (_y-_height/2 _y = topedge+_height/2;
yspeed = -yspeed*bounce;
}
yspeed = yspeed*drag+gravity;
xspeed = xspeed*drag;
} else {
xspeed=_x-oldx;
yspeed=_y-oldy;
oldx=_x;
oldy=_y;
}
}
onFrame (3) {
gotoAndPlay(2);
}

i did this and it didnt work it flew all over the place i jsut want the circle to repeat it self but going up and down

onFrame (1) {
_x=0;
_y=0;
xspeed=Math.random()*60-30;
yspeed=Math.random()*60-30;
rightedge=300;
leftedge=0;
topedge=0;
bottomedge=40;
gravity=1;
drag=.98;
bounce=.9;
}
onFrame (2) {
if (!dragging) {
_x = _x+xspeed;
if (_x+_width/2>rightedge) {
_x = rightedge-_width/2;
xspeed = -xspeed*bounce;
}
if (_x-_width/2<leftedge) {
_x = leftedge+_width/2;
xspeed = -xspeed*bounce;
}
_y = _y+yspeed;
if (_y+_height/2>bottomedge) {
_y = bottomedge-_height/2;
yspeed = -yspeed*bounce;
}
if (_y-_height/2<topedge) {
_y = topedge+_height/2;
yspeed = -yspeed*bounce;
}
yspeed = yspeed*drag+gravity;
xspeed = xspeed*drag;
} else {
xspeed=_x-oldx;
yspeed=_y-oldy;
oldx=_x;
oldy=_y;
}
}
onFrame (3) {
gotoAndPlay(2);
}

Grate Codes i like it very much.

Tried this but variables aren't all initialized. I tried to initialize them from _root but that didn't work, so I tried to initialize them within the same scope and while that worked, all I end up with is a ball that moves right to left slower and slower and does not respond to my dragging.

Bummer.

Good begining. Hope to see more experiments here!

[fedhater]

A good experiment would be 3d collision meshing.
Great work Fudoki

[MrCradler]

Great Code...

[Andrew_F]

Too much errors!!!
The code do not work!
I'll try repair it later...

[Andrew_F]

tryed to initialise variable "dragging" as _global
Then named object ball as "bb", sprite as mm thou, in Scene code:
on (press) {
mm.bb.startDrag(false);
mm.bb.dragging = true;
}
on (release,releaseOutside) {
stopDrag();
mm.bb.dragging = false;
}
in sprite "mm" in this string made:
if (!_root.mm.bb.dragging)
Yeah-h-h-h? after testing no errors, but bouncing only from left to right and does not respond to my dragging!!!
What the matter?

[Andrew_F]

By the way in SwishMax3 I've done something working NOT in internal player (embedded in Swish),but in external.
May be this is a reason?
And what the result from the author himself? His source file swi or flv?
