Array inside a function

pleurespam

I'm trying to create a function has an array of images. However, I keep getting an error. Is it possible to put an array inside a function? If so, how do I do it correctly? If not, what is another way to create a function that has images in it?

Would be helpful if you posted some code and told us what error messages you are getting.

"error message: the method image (PImage,float,float,float,float) in the type PApplet is not applicable for the arguments(PImage[], float,float,int,int)"

void monument(PImage[] img, float x, float y, int sz) {
img = new PImage[10];
for ( int i = 0; i< img.length; i++ ) {
  img[i] = loadImage( i + ".jpg" );
}
if (dist(x, y, mouseX, mouseY) < sz/2) {
  if (mousePressed) {
    cursor(MOVE);
    x = lerp(x, mouseX, 0.2);
    y = lerp(y, mouseY, 0.2);
  } else {
    cursor(HAND);
  }
  cursor(ARROW);
} 
image(img, x, y, sz, sz);

}

Your function above is completely outta touch on how animation is done in Processing! :-??
There are things which should be done in setup() at the top, and the rest in draw() and event functions! [..]
Anyways, the error there is about passing an Array w/o specifying which index to use from it.

As GoToLoop pointed out there are several problems here. This might get you started, but you can find more tutorials on the wiki :

PImage[] img = new PImage[10];
int imgIndex = 0;

void setup(){
    size(400,400); // change to size you want
    // Load images here
    for ( int i = 0; i< img.length; i++ ) {
          img[i] = loadImage( i + ".jpg" );
    }
}

// The draw method is executed ~ 60 times per second
void draw(){
    background(255); // clear background
    monument(img[imgIndex], 10, 10, 200);
}

void monument(PImage pimg, float x, float y, int sz) {
    if (dist(x, y, mouseX, mouseY) < sz/2) {
        if (mousePressed) {
            cursor(MOVE);
            x = lerp(x, mouseX, 0.2);
            y = lerp(y, mouseY, 0.2);
        } else {
           cursor(HAND);
        }
    }
    else {
        cursor(ARROW);
    }
    image(pimg, x, y, sz, sz);
}
