Is there any way to pass the arguments from one class to another?

in Programming Questions • 2 years ago

I have a project I'm working on to make pong for a class I'm taking. I have to put each object in its own class, and so right now I'm trying to pass the arguments for the Paddle locations so that the ball bounces off the paddles when it hits the paddle's coordinates. My professor tried to explain it to me in class but he was in a rush so I did not fully understand, if you could explain how to do this I would appreciate it. Would I need to put it in the main code, or is there a way to pass the arguments to the ball class so that way I can use them.

You could make it a global variable that is accessible from both classes, so it would be part of the main code. Or, you could make a variable accessible inside the class by either making it public or making a function that returned the variable.

Option 1

int pong = 1;
pongclass pc = new pongclass();
pongclass2 pc2 = new pongclass2();
void setup() {
}
class pongclass {
public pongclass() {
println(pong);
}
}
class pongclass2 {
public pongclass2() {
println(pong);
}
}

Option 2

pongclass pc = new pongclass();
pongclass2 pc2 = new pongclass2();
void setup() {
pc.getPong2();
pc2.getPong1();
}
class pongclass {
int pong = 1;
int getPong() {
return pong;
}
void getPong2() {
println(pc2.getPong());
}
}
class pongclass2 {
int pong = 2;
int getPong() {
return pong;
}
void getPong1() {
println(pc.getPong());
}
}
