p5.j​​s mousePressed在第一次迭代后停止

Question

I need just the first click. I cannot do mouseClicked() because it does not allow you to get the mouse button clicked (left or right). Anyone know any workarounds? I'm not opposed to doing this in vanilla js but I was wondering if anyone with more knowledge in p5 than me knows how to do this.

Answer 1

you can check if mousePressed once via this

int pressed = false;
mousePressed(){
    if(!pressed){
        //run code
        pressed=true;
    }
};
mouseReleased(){
    pressed=false;
};

As i learned how to code on a processingJS on khan academy which is extremely close to p5.js

EDIT looking at https://processing.org/tutorials/interactivity/ I learned that it isnt button it is mouseButton so if you run

mouseClicked(){
    println(mouseButton);  
   //0 === left
   //1 === right
}
