All this functions start as ofUTF8* and if you want to do something with text which might have characters other than ascci, because UTF8 has variable length characters you should be using this functions instead of the corresponding string methods. Its syntax mimics that of glsl so working with it while working with OpenGL, shaders makes things easier cause the syntax is almost the same across the different languages. Recreation Special Events & Activities. There are 545 watchers for this library. for example instead of doing: to insert a character you should be using: or when creating a string from keypresses: theres also ofUTF8Substring, ofUTF8ToString and ofUTF8Length. Up until now listening to an event in OF looked something like: That has several problems mainly if we want to add a class to listen to a mouse event we would be tempted to do something like: So when creating an instance of that class it would listen to the mouse and when the object is destroyed itll remove itself as a listener so theres no calls once the object has been destroyed, otherwise we would get a crash. Then Ring Of Fire . They serve as a fantastic overview of the functionality that openFrameworks provides, as well as a kind of cheat sheet that you can refer back to to see how a particular class, function, or technique works.

Basically I just want to find out where openFrameworks thinks my current directory is, for starters. Weve organized documentation sprints which has been helpful in the short term, but it doesnt take long for the documentation to begin to drift out of sync with this codebase and as it is an area where there isnt active ongoing contributions we believe it needs us to take a different approach. The rest of the clases are mostly data containers that represent different elements, mostly: ofColor for colors, ofRectangle for rectangles!, ofPoint which is an alias for ofVec3f, ofStyle which can hold the whole state of the graphics system and is used internally by OF to keep track of it. But introducing a copy constructor is error prone since from now on well need to copy every new member we add to the class. This is known as Painters Algorithm, and simply put, it just means that things drawn last appear on top. This is mainly for performance reasons, although I find that it encourages a more readable kind of code also. 4th Of July Festivities. This happens when the first OFActivity is created. OF addon to enable retina graphics on iOS app without modifying the original appearance. An ofParameterGroup can also notify when any of it's children changes.

Also when you receive a key event you can also check if a modifier is pressed at the same time using ofKeyEventArgs::hasModifier() as in: hasModifier() also exists for mouse events so you can query it when a mouse event happens as in: The callbacks in ofApp are still the simple ones that just receive the int key for key events and the position x and y and mouse button for mouse events but you can easily change them to: and itll just work without having to explicitly listen to that event. To remedy this problem, we can tell our application that, when we draw a circle, we want to draw something more like a hectogon (100 sided shape). Each function is called automatically by openFrameworks at specific points during the runtime of your application. Like many programming languages, c++ has a special function called main() that is used to kick off the program. OpenFrameworks supplies a base activity called OFActivity when the following conditions suits the project: 1) The first activity is this activity, meaning, the first activity in the application shows a gl canvas. I do not update this site much any more. By being able to pay for some contributions we expect to help overcome that barrier and increase range of people contributing and shaping the future of openFrameworks.
