Background Images

Are there any cheap tricks to having a nice big background image without using a large(800x600) jpg?

My sketch is now very fast since I've gained a lot of fps with a smaller res.

but, its to small... damn you trade-off.

The jitter.... again

Ok, so for the record,

I have slightly more complicated sketch than the one below, but it has almost the same amount of jitter.
As far as processing sketches go, you cant get much simpler than this one.

And still, there is quite a serious jitter, or short jumps, between seemingly random frames.

Could It be my JRE? or my crapy laptop?

does it also do that on your machine?

anyone? Phi.Lo??

<start sketch>

float x, y;
float size = 40.0;

void setup()
{
size(800,150);
noStroke();
frameRate(60);
}

void draw()
{
background(102);

x = x + 2.0;

if (x > width + size) {
x = -size;
}
translate(x, 75);
fill(0);
rect(-size/2, -size/2, size, size);

}

<end sketch>

Mac books being full of @#$*

http://processing.org/learning/basics/keyboard.html

that didn't work on the mac I used for testing...

the mouse starts flickering when I hold down a key. wtf?! (Chrome and safari)

first the keyboard was working, now it freaks out, and doesn't do anything.

mousewheel functions workis differently to the when running on my pc, (should give -1 or 1)

mouse can't move out of the sketch borders when dragging.

generally, macs are full of issues with my sketches.

I work on my old warhorse pc, and all is running well, until I start forwarding links to mac users.

Its killing me.

Anybody else having issues with macs?

Sheeeeshhhhhh.

Preloading images

I made a sketch, where at some point during run time an object gets instantiated and loadShape("my_pic.svg") runs.

It locks up my sketch for a whole second every time.

I need to preload the shapes, but stil be able to reference them deeper down a class structure.

How do you go about loading all your shape and stuff in the start, and still call from within a class without pasing them alll the way down in the constructors?

Mouse Wheel on mac

Hi there,
I'm adding a mouseWheel method to my sketch using these lines from the processing reference page.
1. addMouseWheelListener(new java.awt.event.MouseWheelListener() {
2. public void mouseWheelMoved(java.awt.event.MouseWheelEvent evt) {
3. mouseWheel(evt.getWheelRotation());
4. }});
It works fine on my pc win 7, but my cousin is having trouble on his mac book.

I forwarded him this link to the PeasyCam lib:

http://mrfeinberg.com/peasycam/

he says that mouse wheel zoom on the block works.

what can I tri before digging through the PeasyCam source?

Thanks

OpenGL vs default 2D

I made a cool looking sketch with the default processing drawing:

size(640,480);

it has some ellipse's and some small png's

I'm not sure what the ACTUAL framerate is but I set it 60 with the frameRate(60); func.

It looks good.

But when I import the OPENGL lib, and use:

size(640,480, OPENGL);

the framerate is still good, but every 30 to 40 frames(i think) it has a bit of an hickup.

kinda like a GC hickup, but constantly... why? and is it worth it to tri to implement OPENGL?

can OPENGL make my basic drawing(standerd 2D shapes and some images) sketch go faster and allow my drawing to be more complex in the main loop?

loadShape NullPointerError

I've been working on the "old" processing 1.5.1 and I used loadShape like this.

PShape s;

s = loadShape("spaceship.svg");

...

shape(s,0,0,100,100);

=============

But now I've changed to the "new" (processing 2.0a4) and

loadShape("spaceship.svg");

is giving me a NullPointerException.

I see they say on the website that they have made changes to these functions, and that you should use the default loadShape() function, I thought that i AM using the default loadShape()?

anyway..

Please help, my program is full of SVG's and the need to drawn!

Thanks

Distance without sqrt() func

I'm looking for a function that can give me a good enough distance between two points that does not use the sqrt() function hoping that it will save me some processing time.

Does anyone know of something I can use for this goal?

I don't want to many distance calcs per frame when things go crazy, and hopefully they do... :)

Thanks

Nest Drawing nodes

Hi

Do you think I need check if objects are in the field of view of my 2D world?

I'm scaling and translating things in and out of the screen, was wondering if I need to not draw them at all if they're not visible or do you think I shouldn't worry about that? Something tells me processing is smart enough though.

I'm just trying to keep everything running smooth.

Thanks

Hi eric,

I'm playing with nest, would like to know how I would go about printing a child behind a parent. I looks like you made plans for that to be possible. Please tell me how you would go about doing something like that.

Thanks man Rotti
