Target shooting game.

mickeyj13

Hello, I have a project where we have to make a target shooting game. however, I can't figure out how to work the dist function to figure out if the two circles are touching.

Heres the main class where I am having issues. Thanks in advance for any help

[code below]

Sorry, it formatted weirdly.

class Ball {

  PVector pos;
  PVector velocity;
  PVector acceleration;
  PImage ballImage, targets;
  Boolean alive;
  float rs = random(2,10);
  //float rx=  random(75,1068);
//float ry= random(100,550);


  Ball(PVector v_) {
    pos = new PVector(70, 520);
    velocity = v_;
    acceleration = new PVector(0, 0.2);
    alive= true;

    ballImage= loadImage("Cannonball.png");


  }


   void targetCollision(){
   //noLoop();
   for (int t=0; t<21;t++){
 image(targets,rx, ry);
 if(dist(pos.x, pos.y,rx ,ry )<5){
 hitsCounter++;
   text("Hit", width/2, height/2);
 }
   }

 }

  void move() {
    pos = pos.add(velocity);
    velocity = velocity.add(acceleration);
  }
  void display() {
    pushMatrix();
    translate(pos.x, pos.y);
    image(ballImage, 0, 0);
    popMatrix();
  }

  void smoke(){
  ellipseMode(CENTER);
  for(int i=0; i<20; i++){
    fill(random(20,220));



}

}

  void checkGroundCollision() {
    if (pos.y>546) {
      smoke();
      alive =false;
    }
  }
  Boolean isAlive() {
    return alive;
  }
}

Best is to hit ctrl-t in processing first before copy paste into the forum (https://forum.processing.org).

You can edit your post (click the small gear and the 'Edit').

How to format Code:

empty line before and after the code section

select (highlight) entire code with the mouse

hit ctrl-o OR click the small C in the command bar

mickeyj13

Thanks for that help

Chrisir

please in processing hit ctrl-t to get auto indents in processing

can you post the entire code so that we can run it?

koogs

AND DO IT HERE

don't start a new thread when this one has nothing in it.

Chrisir

5 might be too small here

dist(pos.x, pos.y,rx ,ry )<5){

mickeyj13

whenever I try to paste my code using ctrl-o or the c I get

Chrisir

you solved it?

mickeyj13

No, that's all of the code that we need to use to make the project work. I just can't figure out how to tell when the cannonball and target collided

Chrisir

Please format it better

mickeyj13

I am unsure how to

koogs

edit post, highlight code, press ctrl-o. That's all it needs.

koogs

Then read the Common Questions about arrays because hitcount20 etc is ridiculous.

mickeyj13

Okay, thanks. there's the formatted one

koogs

Line 73 has a loop. But nothing inside the loop changes so you're just doing the exact same test 21 times.

mickeyj13

That's the part where i was trying to test if the cannonball touched the target

TfGuy44

Please use loops. Please. :((
