Overview

An add-on helper to integrate an Undo Engine based on ofxUndo from nariakiiwatani, but simplified to easely use ofParameters and with an ImGui based GUI.

Screenshot

Features

• Controls the ofParameters inside an ofParameterGroup.
• Adds ImGui controls to improve the workflow.
• Files Mode to allow persistent Undo History between App sessions.
• Ram Mode should be faster on big files / too many params scenarios.

• Key Commands:

ENTER : SAVE UNDO CTRL + Z : UNDO CTRL + SHIFT + Z : REDO CTRL + C : CLEAR HISTORY CTRL + S : STATE STORE CTRL + R : STATE RECALL

Usage

• Check the example.

ofApp.h ``.cpp

include "ofxSurfingUndoHelper.h"

include "ofxSurfingImGui.h"

ofxSurfingUndoHelper undoManager; ofxSurfing_ImGui_Manager guiManager;

ofParameterGroup params;

ofApp.cpp

.cpp void ofApp::setup() { params.add(..) // -> add params

undoManager.setup(params);

guiManager.setup(); }

void ofApp::draw() { guiManager.beginWindow(); { undoManager.drawImGui(); } guiManager.endWindow(); }

void ofApp::keyPressed(int key) { if (key == 's') undoManager.doStoreUndo(); } `
