What is the best way for an object to check if it has been clicked on?
Previously I have been using:
//pseudo-code
void mouseClicked(){
loop through array of objects
check if mouseX and mouseY inside the bounds each object in the array
//do something
}
I was wondering if there is a way to get each object to monitor whether it has been clicked and dispense with the array method entirely. Something like this:
class Obj{
void MouseClicked(){
check if in bounds of this instance
//do something
}
}
It appears that mousePressed don't work inside objects - I am guessing this is something to do with them being inside a class.
Am I thinking about this the right way? I haven't used event listeners yet. I'm not sure if they are what I want.
Here's some example code I have been working with:
Circle[] circles = new Circle[11];
void setup(){
size(400,400);
for(int i=0;i<circles.length;i++){
circles[i] = new Circle(i*40,height/2,random(20,30), i);
}
}
void draw(){
for(int i=0;i<circles.length;i++){
circles[i].display();
}
}
class Circle{
float x,y,w,h;
int id;
Circle(float x, float y, float w, int id){
this.x = x;
this.y = y;
this.w = w;
this.h = w;
this.id = id;
}
void display(){
ellipse(x,y,w,h);
}
void mouseClicked(){
/*
I want each circle to check if it has been clicked
Can I do this from inside the circle class?
Is there a way to do this without looping through the array in void draw?
I always sucked at trig and I am currently trying to teach myself polar coordinates (and PVectors). I had an idea to build a line that rotates around a point but will always rotate towards the mouse. However, I think my implementation is probably pretty scrappy (the whole prev/curr angle thing) and the sketch jitters a great deal.
