I'm having a problem to delete 2D primitives, I have tried to create a rectangle in front of those primitives to hide them.
But I have to hide them when I click somewhere, so I guess that my draw() overpass the mouseclicked.
In my code, "maFenetre" is what I would like to hide/delete. So this is my code:
float hauteurR = 700;
float barreFenetre = 50;
float xIcone = 80;
float x = random(0,500);
float y = random(0,800);
color rouge = #FF0000;
color blanc = #FFFFFF;
void setup() {
//colorMode(HSB,360,100,100);
size(1500,1500);
background(#C1C1C1);
}
void rectangle(){
rect((x+largeurR)-xIcone,y,xIcone,barreFenetre);
}
void maFenetre(){
//fenetre
noStroke();
fill(#89E0FF);
rectMode(CORNER);
rect(x,y,largeurR,hauteurR);
//barre croix
rectMode(CORNER);
fill(blanc);
noStroke();
rect(x,y,largeurR,barreFenetre);
if ((mouseX>= (x+largeurR)-xIcone && mouseX <= x+largeurR) && (mouseY >= y && mouseY <= y+barreFenetre)) {
fill(rouge);
rectangle();
}
//barre aggrandir
if ((mouseX>= (x+largeurR)-xIcone*2 && mouseX <= (x+largeurR)-xIcone) && (mouseY >= y && mouseY <= y+barreFenetre)) {
fill(#CEDDDE);
noStroke();
rect((x+largeurR)-xIcone*2,y,xIcone,barreFenetre);
}
//barre reduire
if ((mouseX>= (x+largeurR)-xIcone*3 && mouseX <= (x+largeurR)-xIcone*2) && (mouseY >= y && mouseY <= y+barreFenetre)) {
fill(#CEDDDE);
noStroke();
rect((x+largeurR)-xIcone*3,y,xIcone,barreFenetre);
}
//icone réduire
stroke(#000000);
strokeWeight(2);
line((x+largeurR)-xIcone*2.65,y+barreFenetre/2,(x+largeurR)-xIcone*2.35,y+barreFenetre/2);
//icone aggrandir
stroke(#000000);
strokeWeight(2);
noFill();
rectMode(CENTER);
rect((x+largeurR)-xIcone*1.5,y+barreFenetre/2,20,20);
//icone croix
stroke(#030303);
strokeWeight(2.5);
line((x+largeurR)-xIcone*0.62,y+barreFenetre*0.35,(x+largeurR)-xIcone*0.38,y+barreFenetre*0.75);
line((x+largeurR)-xIcone*0.62,y+barreFenetre*0.75,(x+largeurR)-xIcone*0.38,y+barreFenetre*0.35);
}
void draw() {
maFenetre();
}
void mouseReleased(){
if (mousePressed == ((mouseX>= (x+largeurR)-xIcone && mouseX <= x+largeurR) && (mouseY >= y && mouseY <= y+barreFenetre))){
}
else{
//background(#C1C1C1);
noStroke();
rectMode(CORNER);
fill(#C1C1C1);
rect(x-1,y-1,largeurR+2,hauteurR+2);
//maFenetre();
}
}```
Deleting an object not drawing it. Add a variable that indicates whether an object needs to be drawn. Change the status of the variable if you want to hide (or show) the object:
boolean drawMyObject = true;
void draw() {
// [...]
rectMode(CORNER);
if (drawMyObject) {
rect(x, y, w, h);
}
}
void mouseReleased(){
if (mouseX >= x-w/2 && mouseX <= x+w/2 && mouseY >= y-h/2 && mouseY <= y+h/2){
drawMyObject = false;
}
