ofxHelpMessage

Overview

This is an addon for openFrameworks. I made it to show help message on window easily.

Requirement

ofxHelpMessage doesn't depend other addons.

Tested system

• Windows 10 + VS2017 + of0.10.1 .

I think compatible almost all versions, because it's simple addon.

Usage

1. Add this addon. 1. Include ofxHelpMessage.h. 1. Put the static method ofxHelpMessage::addMessage("Key S: save") in setup(). 1. When program running, press '?' key to show help message.

You can use some method to change appearance and behaviour. For example.

// add message
ofxHelpMessage::addMessage("HELP (dummy message)");
ofxHelpMessage::addMessage("Key S: Save");
ofxHelpMessage::addMessage("Key L: Load");

// clear message
//ofxHelpMessage::clear();

// set text color
// default: ofColor::white
ofxHelpMessage::setTextColor(ofColor(255, 255, 0));

// set background color
// default: ofColor(0, 0, 0, 150) this is black transparently
ofxHelpMessage::setBackgroundColor(ofColor(0));

// set font
// draw with ofTrueTypeFont if loaded
ofxHelpMessage::loadFont("arial.ttf", 30);

// set position
// default: (10, 10)
ofxHelpMessage::setPos(500, 500);

// change show message key
// default: '?'
ofxHelpMessage::setHelpKey(' ');

// set show mode to momentary/toggle
// default: true (momentary)
ofxHelpMessage::setMomentary(false); // toggle mode
