按钮在 Processing 4 beta 1 中不起作用

Question

我只是无法让我的代码工作。它使按钮，但它不工作。那你能帮我吗？

它使文本正常显示，按钮也出现了。但它不起作用，我也尝试过使用不同的功能，如 background(10) 等

Button login1;
boolean clicked = false;

void setup() {
  fullScreen();
  loginPage();
}

void draw() {
  if (login1.isClicked()) {
    print("AAAA");
  }
  login1.update();
  login1.render();
}

void loginPage() {
  background(27, 50, 131);
  textSize(70);
  fill(255);
  text("System Statku Organizacji 587 'Aurora'", 600, 150);
  login1 = new Button(100,50,400,200,"Zaloguj sie",64, 136, 253,255,255,255);
}

class Button {
 boolean Pressed = false;
 boolean Clicked = false;
 PVector Pos = new PVector(0,0);
 float Width;
 float Height;
 color Colour;
 color textColour;
 String Text;
 
Button(int x, int y, float w, float h, String t, int r, int g, int b, int tr, int tg, int tb) {
 Pos.x = x;
 Pos.y = y;
 Width = w;
 Height = h;
 Text = t;
 Colour = color(r,g,b);
 textColour = color(tr,tg,tb);
}
 
void update() {
  if (mousePressed == true && mouseButton == LEFT && Pressed == false) {
    Pressed = true;
    if (mouseX >= Pos.x && mouseX <= Pos.x+Width && mouseY >= Pos.y && mouseY <= Pos.y+Height) {
    
    }
  } else {  
    Clicked = false;
    Pressed = false;
  }
}
 
 void render() {
   noStroke();
   fill(Colour);
   rect(Pos.x,Pos.y,Width,Height);
   
   fill(textColour);
   textAlign(CENTER,CENTER);
   text(Text,Pos.x+(Width/2),Pos.y+(Height/2));
 }
 
 
 boolean isClicked() {
  return(Clicked);
 }
 
}

将此添加到代码底部（在按钮 class 下方）。我不确定您是否真的需要 Pressed 和 Clicked 布尔值。

void mousePressed(){
 if((mouseX >= login1.Pos.x) && (mouseX <= login1.Pos.x + login1.Width) && (mouseY >= login1.Pos.y) && (mouseY <= login1.Pos.y + login1.Height)){
  println("You hit the login button.");
 }
}
