changing fill color with if() and mouseReleased()

in Programming Questions • 2 years ago

i want this to make a circle each time i make a click, but also that it changes its color from red to green, (green to blue and blue to red, with alpha. ) so each team i click the circle is a different color.

maybe if() is not correct to use with color() but i don't know in what other manner i can do it.

color red= color(255, 0, 0, 10);
color green= color(0, 255, 0, 10);
color blue= color(0, 0, 255, 10);
void setup() {
size(240, 420);
background(255);
smooth();
}
void draw() {
noStroke();
fill(red);
if (mousePressed == true) {
ellipse(mouseX, mouseY, 50, 50);
}
}
void mouseReleased()
{
if (color(red))
{
color(green);
}
{
if(color(green))
{
color(blue);
}
}
{
if(color(blue))
{
color(red);
}
}

thank you

You need to use something like an integer to cycle through 3 different states, then make your fill() function be called with a different colour in the three different states... eg.

color red = color(255, 0, 0, 10);
color green = color(0, 255, 0, 10);
color blue = color(0, 0, 255, 10);
int counter = 1; // your state counter
void setup() {
size(240, 420);
background(255);
smooth();
}
void draw() {
noStroke();
if(counter == 1) {
fill(red);
}
else if(counter == 2) {
fill(green);
}
else if(counter == 3) {
fill(blue);
}
if (mousePressed == true) {
ellipse(mouseX, mouseY, 50, 50);
}
}
void mouseReleased() {
counter++; // increase the counter
if(counter == 4) {
counter = 1; // loop after 3
}
println(counter);
}
