Change fps when the button is pressed

I need to be able to change the fps while the program is running, is it possible? I think the code is right but it doesn’t work :face_with_raised_eyebrow:

import g4p_controls.*;

GImageToggleButton btn1,btn2,btn4,btn8;

public int fps = 30;

public void setup(){
  
 size(1200,700);
 frameRate(fps);
 //G4P.setCursor(ARROW);
   
  btn1 = new GImageToggleButton(this, 1050,400,"imagens/1x.png",1,1);
  btn2 = new GImageToggleButton(this, 1100,400,"imagens/2x.png",1,1);
  btn4 = new GImageToggleButton(this, 1050,450,"imagens/4x.png",1,1);
  btn8 = new GImageToggleButton(this, 1100,450,"imagens/8x.png",1,1);
  
 }

public void draw(){
  background(0);
  println(frameRate);
 }

public void handleToggleButtonEvents(GImageToggleButton button, GEvent event) { 
  //println(button.getState());
  if(button == btn1){
    println("botao 1x pressionado");
    fps = 30;
  }
  if(button == btn2){
  println("botao 2x pressionado");
  fps = 60;
  }
  if(button == btn4){
   println("botao 4x pressionado"); 
   fps = 120;
  }
  if(button == btn8){
   println("botao 8x pressionado"); 
   fps = 240;
  }
}

Hey There!

Yes it possible. But to change FPS in running time you need to call frame rate in draw.

haha, so simple! Thanks!!

Note to add to update that you should only change the frame rates when you click each button. Rather than in raw draw. This will just save some resources.

I set the frameRate() with each button press.

I have an NVIDIA card and with Vertical sync (On) the frame rate is limited to 60 (my monitor refresh rate). I can always use other settings if I wish; this was my setting at the time.

With Vertical sync (On):

size(1200,700);  //I can set 30, 60, 120, 240

size(1200,700, P2D); //I can set 30, 60 and it is limited to 60

size(1200,700, P3D); //I can set 30, 60 and it is limited to 60

Have fun!
