ofxSceneManager duplicate scenes

beginners
#1

hello
i try to test ofxSceneManager addon to switch some sketch and examples, but when I compile, change scenes, they will copy!

when compile, show the first scene normal:

change to the second scene, normal.
2.jpg1068×834 155 KB

change to the first scene again. double gui…
3.png1108×874 25.3 KB

change to the second scene… double particle system.
4.jpg1068×834 202 KB

change to the first scene… triple.

the code:

#include "ofApp.h"
#include "msafluids/FirstScene.h"
#include "wiiacuarium/SecondScene.h"

//--------------------------------------------------------------
void ofApp::setup(){
    server.setName("The Floor");
    FirstScene* firstScene = new FirstScene;
    firstScene->setSceneDuration(0.5, 1.5, 0.5);
    
    SecondScene* secondScene = new SecondScene;
    secondScene->setSceneDuration(0.5, 3.0, 0.5);
    
    sceneManager.addScene(ofPtr<ofxScene>(firstScene));
    sceneManager.addScene(ofPtr<ofxScene>(secondScene));
    //sceneManager.setExitByTime(true);
    
    sceneManager.setTransitionDissolve();
    //sceneManager.setTransitionFade();
    
    sceneManager.run();
}

//--------------------------------------------------------------
void ofApp::update(){
 sceneManager.update();
}

//--------------------------------------------------------------
void ofApp::draw(){
    sceneManager.draw();
    server.publishScreen();
    ofSetColor(255);
    ofDrawBitmapString("scenes: "+ofToString(sceneManager.scenes.size()), 10,10);
}

//--------------------------------------------------------------
void ofApp::keyPressed(int key){
    if (key == ' ') {
        sceneManager.changeScene();
    } else if (key == '0') {
        sceneManager.changeScene(0);
    } else if (key == '1') {
        sceneManager.changeScene(1);
    }
}

anything work with this addon? eny help?

thanks community!!!

Hi
You should show here the first scene code

#3

My guess is you’re calling GUI construction in setup() method of your scene,
and setup() in ofxScene is called each time this scene is called (when you call changeScene)

#4

gui and particle system called in setup() of scene scene

#5 
#include "FirstScene.h"

//--------------------------------------------------------------
void FirstScene::setup() {
    ofSetLogLevel(OF_LOG_VERBOSE);
    
    isGui = true;
	
	// setup fluid stuff
	fluidSolver.setup(100, 100);
    fluidSolver.enableRGB(true).setFadeSpeed(0.002).setDeltaT(0.5).setVisc(0.00015).setColorDiffusion(0);
	fluidDrawer.setup(&fluidSolver);
	
	fluidCellsX			= 150;
	
	drawFluid			= true;
	drawParticles		= true;
    
    tuioXScaler = 1;
    tuioYScaler = 1;
	
	ofSetFrameRate(60);
	ofBackground(0, 0, 0);
	ofSetVerticalSync(false);
	
	tuioClient.start(3333);
	
	gui.addSlider("fluidCellsX", fluidCellsX, 20, 400);
	gui.addButton("resizeFluid", resizeFluid);
    gui.addSlider("colorMult", colorMult, 0, 100);
    gui.addSlider("velocityMult", velocityMult, 0, 100);
	gui.addSlider("fs.viscocity", fluidSolver.viscocity, 0.0, 0.01);
	gui.addSlider("fs.colorDiffusion", fluidSolver.colorDiffusion, 0.0, 0.0003);
	gui.addSlider("fs.fadeSpeed", fluidSolver.fadeSpeed, 0.0, 0.1);
	gui.addSlider("fs.solverIterations", fluidSolver.solverIterations, 1, 50);
	gui.addSlider("fs.deltaT", fluidSolver.deltaT, 0.1, 5);
	gui.addComboBox("fd.drawMode", (int&)fluidDrawer.drawMode, msa::fluid::getDrawModeTitles());
	gui.addToggle("fs.doRGB", fluidSolver.doRGB);
	gui.addToggle("fs.doVorticityConfinement", fluidSolver.doVorticityConfinement);
	gui.addToggle("drawFluid", drawFluid);
	gui.addToggle("drawParticles", drawParticles);
	gui.addToggle("fs.wrapX", fluidSolver.wrap_x);
	gui.addToggle("fs.wrapY", fluidSolver.wrap_y);
    gui.addSlider("tuioXScaler", tuioXScaler, 0, 2);
    gui.addSlider("tuioYScaler", tuioYScaler, 0, 2);
    
	gui.currentPage().setXMLName("ofxMSAFluidSettings.xml");
    gui.loadFromXML();
	gui.setDefaultKeys(true);
	gui.setAutoSave(true);
    gui.show();
	
	//windowResized(ofGetWidth(), ofGetHeight());		// force this at start (cos I don't think it is called)
	pMouse = msa::getWindowCenter();
	resizeFluid			= true;
	
	ofEnableAlphaBlending();
	ofSetBackgroundAuto(false);
}

you should use single instance

where?

As I said, you must not create your gui in setup() of your ofxScene, it is called each time the scene is changed.

sceneManager.changeScene(0);

-> calls setup()

You should create an init() or initGUI() method and call it when you create your scene

FirstScene* firstScene = new FirstScene;
firstScene->setSceneDuration(0.5, 1.5, 0.5);

firstScene->initGUI()
