I'm working on a kind of map with different points in which when the user hovers over them, text appears. However, when I hover over a point, the text prints over and over again (on top of the previous text), but I only want it to display once when I'm hovering over.

my draw() function:

void draw()
{
 update(mouseX, mouseY);
 
 noStroke();
 if (btnOver) {
   fill(95);
   textover("JHE (John Hodgins Engineering)");
 } else {
   background(222);
 }
 
 stroke(255);
 fill(btnColour);
 ellipse(btnX, btnY, btnSize, btnSize);
}



and my textover function:

void textover(String s)
{
 fill(95);
 text(s, btnX+12, btnY+6);
}


Thanks for your help.
