Stop blinking

mma

Hi I'm new to processing and I was trying different codes but it seems that everytime I use the mouseMoved and mouseDragged my screen starts flashing or blinking instead of just showing me what I want according to the code. It would be really helpful please, thank you.

boolean drawA = false;

boolean drawB = false;

boolean drawC = false;

void setup() {

size(600, 600);

noStroke();

background(255);

}

void mouseMoved(){

background(126);

float x = mouseX;

float y = mouseY;

float ix = width - mouseX; // Inverse X

float iy = height - mouseY; // Inverse Y

fill(255);

triangle(x, height/2, y, y,ix,iy);

fill(0);

ellipse(ix, height/2, iy, iy);

}

void keyPressed() {

if ((key == 'A') || (key == 'a')) {

drawA = true;

} else if ((key == 'B') || (key == 'b')){

drawB = true;

}else if ((key == 'C') || (key == 'c')){

drawC = true;

}

}

void keyReleased() {

drawA = false;

drawB = false;

drawC = false;

}

void mouseDragged(){

background(255);

fill(0);

ellipse(mouseX,mouseY,70,70);

}

void draw() {

background(255);

fill(0);

if (drawA == true) {

ellipse(100,300,25,25);

} else if(drawB == true) {

quad(290,0,290,600,310,600,310,0);

} else if (drawC == true){

triangle(500,200,400,400,600,400);

}

}

edit post, highlight code, press ctrl-o to fix formatting.

it's the background calls. remove them all apart from the one in draw().

if you need to change them based on mouseDragged / mouseMoved, set a flag and check it in draw()

Thank you so much, it's just that I'm really new to this. Could you help me by showing me how the code it's supposed to be please? I'm sorry

@mma as koogs requested, please edit your post above, highlight the code, and press ctrl-o to fix formatting.

Once that is done, it is much easier to read and understand your code.
