Stack Animation Development

[Panta]

Next, I might do "fireworks"! :cool:

This one promises to be explosive! I want it!!

Now, let me download your new effects and give them a try...

btw, Thanks!

Great! you can help me then! I still haven't even been introduced (in school) to grade 10 trigonometry yet :slant:. Can you write a direction (in radians) function from 0 to 2pi in math? Arguments are x1,y1,x2,y2. Return from 0 to 2pi radians

Edit: so if (x1,y1) was the center of a circle, (x2,y2) is a point on the circle represented as (cos θ, sin θ) and I need θ

Edit2: either arctan((y2-y1)/(x2-x1)) isn't working, or my bug lies elsewhere.

Edit3: I don't know delphi either I'm really just learning as I go along. Take a look at online pascal tutorials.

Edit4: I'm an idiot, I figured it out

Edit5: Hehe, I've almost got it now. Just need to make a matching fan animation and I'm all set

Edit6: Alright. I released it into the other thread. It's now available in all its bezier-curve goodness

Where did you post your new bezier-curve goodness animation. In the skins, you have the wobble and expand, but not bezier-curve.

And what's the difference between expand and wobble, I tested them both out, 1 after the other, and can't see a difference.

EDIT: ok so the Wind animation is the bezier-curve animation.

Also, to be truthful, I personally like fountain better than fountain2. Also, I cant decide which animation to use, Deal or Wind, because they're both awesome. Hopefully in newer versions, different stacks can have different effects.

Fireworks has been made need more ideas!

@Atreiu: I haven't yet gone and taken a detailed look at fan stacks. However, I can report that index 0 is the topmost icon, and index count-1 is the lowermost icon. Could you do a dump of the following?

Width

Height

Width2

MaxCount

I have no idea what they might be... Max Count might be the "auto mode threshold" in the settings.

Edit2: ugh... having come up with a much simpler implementation of bezier curves, I want to shoot myself.

Edit: added optional obfuscated code

Hi Andrew, your tutorial on Animation will help a lot, i think! Thanks.

To do a Dump add this to the end of your GetFanRect()

  // *** here you put together, what shall be dumped in one line. ***
  // use IntToStr(value) to dump Integer values
  // use IntToStr(round(value) to dump Real values rounded to Integer or
  // use FloatToStr(vaule) to dump Real values completely.
  outStr:= IntToStr(k1)+';'+IntToStr(k2)+';'+IntToStr(width)+';'+IntToStr(height)+';'+
		   IntToStr(Width2)+';'+IntToStr(Index)+';'+IntToStr(Count)+';'+IntToStr(MaxCount)+';'+
		   IntToStr(Result.Left)+';'+IntToStr(Result.Top)+';'+
		   IntToStr(Result.right)+';'+IntToStr(Result.Bottom)+';';

  // *** here you write your String to the dump-file ***
  assignfile(datei, 'C:dump.txt');  // <-- File name of the dump
  if FileExists('C:dump.txt') then  // if File exists, append the line, if not, create the File
	Append (datei)
  else
	rewrite(datei);
  writeln(datei, outStr); // write your Line
  closefile(datei);

To your var-section add:

var
  datei: Textfile;
  outStr: String;

Cool after the dump, this is what I get:

Hey Andrew, how about a nuke mushroom effect?

[AndrewYY]

Hey Andrew, how about a nuke mushroom effect?

Haha. No limit to the excitement eh? I'll work on it tomorrow if I have time

[Panta]

Yeah, you know, XWD is da bombshell!!

[haran]

Yeah, you know, XWD is da bombshell!!

haha yea but how would that work? 1 item coming from the top to bottom, then they all explode into position? Sounds pretty cool.

[AndrewYY]

Yes I was gonna ask how it works too o_O

@Panta: Could you draw out (in paint or whatever) the path the icons will follow? I'm having troubles visualizing the direct path... I figured we were going for the mushroom cloud effect, but I'm not sure if I can do that without a: intense coding, or b: ugliness

Edit: this is what I was thinking:

[Panta]

Me too... only as one grid I use has 63 icons, the mushroom would be more impressive! But the general idea is exactly this one you depicted.

btw, after that, ... spirals!!

Funny, i had a very similar idea last evening. I call it "snake" (you remember the number-eating ascii-reptile? ) It would be something like in the screenshot. Red-path would be easier, I guess, something like the green-path would be more interesting (i love asymetrical animations like Wind)

I can never do this, but if Andrew likes the idea, maybe he does

Ugh.... looks like a huge pain in the... to implement Both paths look pretty hard. For one thing, I can't tell how many icons are in every row/column because the last row can be different, and anything past the first column can be different

I'd have to loop through everything once, store the values somewhere, and re-call them. Way too much work for just a simple animation

hehe, no problem.

Could someone link me to a page on working with arrays in pascal/delphi and possibly the functions that have to do with arrays? Since this animation is really complex, I figured I'd need to store things in a 2d array...

Gah. This is gonna hurt

Hehe. Good. I love dynamic arrays. So much less work . Any programming language without 'em should be shot o_O.

Thanks for the link. Everything is working well.
