Hello,

I am doing like a space invaders game and there's everything ok. But the only way I have to move my spaceship is using the mouse, and I also need to add keyboard movements (left, right and space to shoot), but I don't know how. Please help me!

PImage img;
PImage studio;
PImage story;
PImage year1;
PImage studioc;
PImage storyc;
PImage yearc;
PImage background;

void setup(){

studioc=loadImage("studiocortina.jpg");
storyc=loadImage("storycortina.jpg");
yearc=loadImage("yearcortina.jpg");
background= img;

}

void draw(){
    image(studioc,0,0,width,height);
    image(storyc,0,0,width,height);
    image(yearc,0,0,width,height);
    image(background,0,0,width,height);

}

void mousePressed(){
    if(mouseX>200 && mouseX <300 && mouseY>500 && mouseY <580){
      background=studioc;
      } else if(mouseX > 400 && mouseX < 500 && mouseY > 500 && mouseY < 580){
      background = storyc;
} else if (mouseX > 600 && mouseX < 700 && mouseY >500 && mouseY < 580) {
      background = yearc;
}
}

When I click on a button (for example 'studio') it appears a new background and I need that in that new background show me a text file that when I click it will appear the whole information.

Please help me.

I need some help to create buttons. I want to click on a button created with an image and change the whole 'background' and then it appears OTHER button (image) with the same function (and on and on and on). Please help me. I don't really know how to do and I need this to do an assignment.

for example:

background1 (img1)
background2 (img2)
button1 (b1)
button2 (b2)
.
.
.

I want to have the img1 and the b1, and when I click on b1 it change to img2 with b2...

how do I click on an image to go to a different one?

I'm new here and I wanna know how do I click on an image (like a button) and it appears a different one (like a new page). This is to do like a 'data file', or like a program that shows me new information when I click on that image (like a web page).

example:

void setup()
{
size(850 ,638);
background(0);

PImage img;

img = loadImage("cortinaanimationfilms2.jpg");

image(img,0,0);

img = loadImage("story2.jpg");

image(img,600,500);

img = loadImage("studio2.jpg");

image(img,200,500);

img = loadImage("year2.jpg");

image(img,400,500);
}

void draw()
{}

-------------------------------------------------------------

I have "cortinaanimationfilms2.jpg" as a background and I wanna click on "story2.jpg" to show me a different page(image). Can you help me please? It's for college and it's kind of urgent...
