As2 Basics: Vcam, Rolling physics and much more!

Latest tutorial, talkin' 'bout Rolling physics and vCam, along with some other little basics. Here's the link if you wanna play the engine: http://spamtheweb.com/ul/upload/210110/55903_roll.php

Vcam link: http://bryanheisey.com/blog/?page_id=19

Actionscript:

Dude:
onClipEvent (load) {
var Rotation:Number = 0;
}
onClipEvent (enterFrame) {
this._rotation += Rotation;
this._x += Rotation;
if (Key.isDown(Key.LEFT)) {
Rotation -= 1;
}
if (Key.isDown(Key.RIGHT)) {
Rotation += 1;
}
if (!Key.isDown(Key.RIGHT) and (!Key.isDown(Key.LEFT) and (Rotation-"fewer than" symbol-0))) {
Rotation += 0.25;
}
if (!Key.isDown(Key.RIGHT) and (!Key.isDown(Key.LEFT) and (Rotation-"greater than" symbol-0))) {
Rotation -= 0.25;
}
}

Shadow code:

onClipEvent (enterFrame) {
this._x = _root.dude._x;
}

vCam code:

onClipEvent (enterFrame) {
this._x = _root.dude._x;
this._y = _root.dude._y;
}

How do you make the ball roll along a ground and, more importantly, up/down a hill?

[roojames]

@Bikkits This is a lot harder of a thing to do than you probably expect - if you're trying to have grounds at different levels you're better off trying to combine the code from this tutorial with that of a traditional platformer tutorial. As for hill physics, that's really advanced stuff. I can make a hill engine, but it'd be very hard to teach it as my tutorials are generally aimed at beginners.

[zitroooz]

Hi I don't know if you do this anymore, but I would like to know if there is some way to have like a wall stoping the speed and rotation like a wall would.

[roojames]

@zitroooz Sorry for the 3 part answer (damn character-count), but if that was too complicated for you, I'm about to make a tutorial about it.

[JhamPowL19]

i have a question..how can you put a word in v-cam?

[PsychoNinjaPirate]

Thanks dude

[Bikkits]

@roojames Okay so...

I've copied code from two sources now but from either one when the ball touches the ground it starts bouncing like crazy.

Code: /watch?v=BCPwTIsSVSw

Also, thew ball falls through all the platforms but the first one it lands on.

Damn... this is harder than I ever thought it would be.

[alexk175]

Great tutorial for beginners, but sorry, i already knew how to do this. In fact, I want to put a gravity in so it doesn't bounce upon hitting the ground... but mine still vibrates. I would love some help- alex

[roojames]

@HueyF003 a'ight send me all of your code via a private message and I'll see what I can do

[HueyF003]

@roojames Im STOMPED man, i can't figure out what im doing wrong, do you think you can send me a code, or i can send you the code for my character and you can use your more experienced eye to see if you can spot the error, if you have time of course? I would REALLY appreciate it.

[zitroooz]

@roojames I found a way by trying some stuff.. took a while but I got it done. :)

[HueyF003]

@roojames thx for responding man, yea i kno about the instance name, my characters instance name is "player" so i normally just change it in your code, i looked at your character animation tutorial to get my character to move, but you didn't add a jump or gravity so i got that from another tutorial, maybe the two different codes are throwing things off, what do u think, because i am stumped right now :(

SN: I'll check for curlies, hopefully it's something that simple
