How Use animation in processing

in Programming Questions • 1 year ago

I created a simple animation. To animation work correctly I should use background(0) under draw().

Now I want to use this animation in main processing file. Actually this animation is a class of main file.

But if I use background in class all the background of main file will be affected. What should I do?

Is there another way for using animation in processing?

int nFrame =2;
int frame = 0;
PImage[] img = new PImage[nFrame];
void setup()
{
frameRate(5);
img [0] = loadImage("01.gif");
img [1] = loadImage("02.gif");
}
void draw()
background(0);
frame++;
if (frame == nFrame)
{
frame =0;
}
image(img[frame], 0,0);
}

If the main draw() loop has a background() call already, and everything is redrawn on each frame, you just have to display the right animation frame when asked.

I call animation class after main draw loop that has background, but the animation doesn’t work correctly.

BTW, Can we use ready animation with other extensions like (e.g gif, jpg …) in processing? And then moving the the animation for instance via mouseX & mouseY

Only Gif has animation capabilities, and to use it in Processing, you must use the GifAnimation library.
And I don't understand what " doesn’t work correctly" covers exactly.

I mean both frames overlap each other at the same time. In the other words I see both frames at the same time. But what I want is to see first frame and then the first frame hide and see the second frame and so on.

If draw() is calling background(), it should erase the previous frame, so I don't see where the problem is.

The code that I sent before, I used it in the frame class :

class frame
......
....
void animation()
{
// I don't use background() here
frame++;
if (frame == numFrame)
{
frame = 0;
}
image(img[frame], 0, 0);Then in the mein draw I call the class:

Maybe the problem is because I use image(firstPage,0,0) as a background

//In the main draw I call the frame class
void draw()
{
background(0); // I used background here
image(firstPage,0,0);
frame.animation(); // calling animation

But I encounter problem
