Hi guys, I'm having some problems with an interactive instalation...the idea is to have a kiosk where a tree will be (pics here: http://antoniopdgomes.wordpress.com/) and by sensors, I want to trigger some animations....my problem is, as it is right now, my code is very slow so I created gif files but I have no idea on how to adapt this....anyone can help me? for "B" i made a mix_CaseB.gif, better than loading 600png's like i'm doing now i guess...thanks in advance for any help u can give me

(I had the topic previously but i hit trash by mistake --')

PImage bg;
int b; int c; int a; int z;
int bb; int cc; int aa;
int Baa;
int i =1; int m =1; int s =0; int v =176;
int j =0; int p =0; int w = 180;
int k =20; int l =136;
int mode = 0;
boolean a_mode=false;
boolean b_mode=false;
void setup()
{
size(1005, 1005);
frameRate(15);
background(255);
PImage z;
z = loadImage("back.jpg");
image(z,2,2);
}
void draw()
{
PImage z;
z = loadImage("back.jpg");
image(z,2,2);
if (a_mode) // A 출력 모드일때
{
Agroup();
}
if (b_mode) // B 출력 모드일때
{
Bgroup();
}
}
void keyReleased()
{
if (key == 'a' || key == 'A')
{
a_mode = !a_mode;
}
else if (key == 'b' || key == 'B')
{
b_mode = !b_mode;
}
}
void Agroup()
{
if (j <= 601)
{
PImage aa = loadImage("AA_00"+nf(j,3)+".png");
image(aa,2,2);
println(j);
++j;
} else {
j=0;
a_mode = false;
background(0); // Or other color
}
}
void Bgroup()
{
if (p <= 629)
{
PImage aa = loadImage("BB_00"+nf(j,3)+".png");
image(aa,2,2);
++p;
} else {
p=0;
mode = 0;
background(0); // Or other color
}
}

At first glance, don't load an image in the draw. Do this in your setup.

PImage z;
void setup() {
z = loadImage("back.jpg");
}

Thanks!!! My mistake...changed it now, but it doesn't solve anything....whatever framerate i use, it's still veryyyyy slow loading everything ;)

I see you also load the others in the draw(). I'd create a PImage[] and load all your images in setup. Then just call the appropriate image. You're not going to get good performance trying to read images from the disk 60 times a second. Load once, draw many.

Oh, and this probably isn't helping, unless you want 15 frames a second.

frameRate(15);

Maybe something like this...

PImage bg;
int b;
int c;
int a;
int z;
int cc;
int Baa;
int i =1;
int m =1;
int s =0;
int v =176;
int j =0;
int p =0;
int w = 180;
int k =20;
int l =136;
int mode = 0;
boolean a_mode=false;
boolean b_mode=false;
PImage[] aa, bb;
void setup()
{
size(1005, 1005);
background(255);
aa = new PImage[602];
bb = new PImage[630];
for (int i=0;i<= 601;i++) {
aa[i] = loadImage("AA_00"+nf(i, 3)+".png");
}
for (int i=0;i<=629;i++) {
bb[i] = loadImage("BB_00"+nf(i, 3)+".png");
}
}
void draw() {
if (a_mode) // A 출력 모드일때
{
Agroup();
}
if (b_mode) // B 출력 모드일때
{
Bgroup();
}
}
void keyReleased()
{
if (key == 'a' || key == 'A')
{
a_mode = !a_mode;
}
else if (key == 'b' || key == 'B')
{
b_mode = !b_mode;
}
}
void Agroup()
{
if (j <= 601)
{
image(aa[j],2,2);
println(j);
++j;
}
else {
j=0;
a_mode = false;
background(0); // Or other color
}
}
void Bgroup()
{
if (p <= 629)
{
image(bb[p],2,2);
++p;
}
else {
p=0;
mode = 0;
background(0); // Or other color
}
}

Thank you so much! I understand the concept of loading the images before i actually use them however i have to try with smaller png's, as is, out of memory after 1xx images.....same for my 1.4mb gif file, doesn't load --'

I can't really make smaller png's, I tried running in a powerful computer but no luck, not even with 1gb memory dedicated....but i don't think there's anything wrong with the last code jeff kindly posted....any ideas what's going on?

Thank you so much!

yeah...i raised up to 800mb but no luck --' it says is out of memory, either because of an infinite array or loading thousands of images....which is the case

Have you changed the memory settings in the PDE? Java needs to be told how much memory (min and max) it can use.

If you can except the transition delay, you could load A & B independently, erasing the other as you change. This would allow you to consume half the memory, since only A is loaded, or B, not both.

Perhaps something like this...

PImage bg;
int b;
int c;
int a;
int z;
int cc;
int Baa;
int i =1;
int m =1;
int s =0;
int v =176;
int j =0;
int p =0;
int w = 180;
int k =20;
int l =136;
int mode = 0;
boolean a_mode=false;
boolean b_mode=false;
boolean loading = false;
PImage[] aa, bb;
void setup()
{
size(1005, 1005);
background(255);
textAlign(CENTER);
textSize(30);
fill(0);
}
void draw() {
background(255);
if (!loading) {
if (a_mode) // A 출력 모드일때
{
Agroup();
}
else if (b_mode) // B 출력 모드일때
{
Bgroup();
}
else {
text("Waiting for Input...", width/2, height/2);
}
}
else {
text("Loading...", width/2, height/2);
loading = false;
}
}
void keyReleased()
{
if (key == 'a' || key == 'A')
{
a_mode = !a_mode;
if (a_mode) {
loading = true;
}
}
else if (key == 'b' || key == 'B')
{
b_mode = !b_mode;
if (b_mode) {
loading = true;
}
}
}
void Agroup()
{
bb=null;
if (aa == null) {
cursor(WAIT);
aa = new PImage[602];
for (int i=0;i<= 601;i++) {
aa[i] = loadImage("AA_00"+nf(i, 3)+".png");
}
cursor(ARROW);
}
if (j <= 601)
{
image(aa[j], 2, 2);
println(j);
++j;
}
else {
j=0;
a_mode = false;
background(0); // Or other color
}
}
void Bgroup()
{
aa=null;
if (bb == null) {
cursor(WAIT);
bb = new PImage[630];
for (int i=0;i<=629;i++) {
bb[i] = loadImage("BB_00"+nf(i, 3)+".png");
}
cursor(ARROW);
}
if (p <= 629)
{
image(bb[p], 2, 2);
++p;
}
else {
p=0;
mode = 0;
background(0); // Or other color
}
}
