Hi i tried several ways to get a linear Gradient to my buttons, simple form blue to red ....

i defined a Button class, where the color of the button changes for example when its pushed, including several more things.

Is there a easy way to include a linear gradient for that buttons ?

1.  TempButton(int xPos, int yPos, int buttonWidth, int buttonHeight, int redColor, int greenColor, int blueColor) {
   
       this.x = xPos;
       this.y = yPos;
       this.w = buttonWidth;
       this.h = buttonHeight;
      
       this.r = redColor;
       this.g = greenColor;
       this.b = blueColor;
      
       this.r_h = this.r + 20;
       if(this.r_h > 254) this.r_h = 254;
      
       this.g_h = this.g + 20;
       if(this.g_h > 254) this.g_h = 254;
      
       this.b_h = this.b + 20;
       if(this.b_h > 254) this.b_h = 254;
     }
   
   
     void render() {
    
       if ((mouseX >= x) && (mouseX <= x+w) && (mouseY >= y) && (mouseY <= y+h)) {
   
         hasFocus = true;
         isActive = true;
        
        
         fill(r_h, g_h, b_h);
         stroke(r_h, g_h, b_h);
   //drow
         rect(x, y, w, h);
   

Hi again,

sorry i am new to processing and programming.
I want to increase a counter +1 if i hit a key,  for example the "b" key on the keyboard.

The Problem is when i hit the key the counter doesn't stop by increasing one,
it counts on and on.

thats what my code is :

 
int count;

     void setup() {
       size(400, 400);
       stroke(255);
       background(192, 64, 0);
     }


// Click on the window to give it focus,
// and press the 'B' key.

void draw() {
  if (keyPressed == true) {
    if (key == 'b' || key == 'B') {
      count++;
      }
    } else {
    count=count;
  }
   
switch(count) {
  case 0:
    println("Zero");  // Does not execute
      rect(25, 25, 50, 50);
    break;
  case 1:
    println("One");  // Prints "One"
      rect(25, 25, 80, 80);
    break;
   
      case 2:
    println("two");  // Prints "One"
      rect(25, 25, 100, 100);
    break;
   
          case 3:
    println("three");  // Prints "One"
      rect(25, 25, 150, 150);
    break;
}
}

It would be realy nice if someone could fix me that !

Hi, sorry i am complete new to processing,

is it possible to build a button that does on every click something new what i define before ?

Example:
I made a new class for the button where the buttons settings are defined. (a number a color and some further stuff).
Now on the interface i want only one Button in the middle of the screen, the color and the number of that Button should change on every click.

For Example click1(red, number1), click2(green,number2),...click5(white,number5) after 5 clicks i can disappear.

Would be nice if you can help me with an example !
