nice!
concerning my oop tutorial: i didn't talk about the "constructor" concept, which can be quite useful,
here's how it can be applied to your "lines_7b.pde" example:
when you initialize your object-instances, it goes like:
Code: for (int i = 0; i < count; i++) {
myThings[i] = new Thing();
myThings[i].x = random(0, width);
myThings[i].y = random(0, height);
myThings[i].init_x = myThings[i].x;
myThings[i].init_y = myThings[i].y;
myThings[i].x2 = myThings[i].x;
myThings[i].y2 = myThings[i].y;
myThings[i].x3 = myThings[i].x;
myThings[i].y3 = myThings[i].y;
myThings[i].make_color();
myThings[i].this_thing = i;
} |
|
instead, you could have a "constructor", placed inside your class declaration, as follow:
Code:Thing(float myX, float myY, int myI)
{
x = init_x = x2 = x3 = myX;
y = init_y = y2 = y3 = myY;
make_color();
this_thing = myI;
} |
|
then, in order to initialize your object instances, it would go as follow:
Code:for (int i = 0; i < count; i++) {
myThings[i] = new Thing(random(0, width), random(0, height), i);
} |

useful no?

really? I thought that was the worst one. I guess I've always preferred things that (at least try to) disguise what's actually happening and that one sort of just lets it all hang out there... some latent programming-confidence-issues maybe. hah!
hey, thanks so much for your help (again) ariel. that really does clean things up,

I liked 3 very much as well, very modern art-esque.
The dark ones are also eerily cool.
Awesome!
