In this theory, recognition only involves the latter of these two stages, or processes, and this is thought to account for the superiority of the recognition process over recall. Recognition only involves one process in which error or failure may occur, while recall involves two. child to scene scene->addChild(layer) // return.

Īnother two stage theory holds that free recall of a list of items begins with the content in working memory and then moves to an associative search Encoding specificity However, recall has been found to be superior to recognition in some cases, such as a failure to recognize words that can later be recalled. With the default Cocos2dx template the back button on your phone wont close the application. The theory of encoding specificity finds similarities between the process of recognition and that of recall. The encoding specificity principle states that memory utilizes information from the memory trace, or the situation in which it was learned, and from the environment in which it is retrieved.
In other words, memory is improved when information available at encoding is also available at retrieval. Encoding specificity helps to take into account context cues because of its focus on the retrieval environment, and it also accounts for the fact recognition may not always be superior to recall.įor example, if one is to learn about a topic and study it in a specific location, but take their exam in a different setting, they would not have had as much of a successful memory recall as if they were in the location that they learned and studied the topic in. Philosophical questions regarding how people acquire knowledge about their world spurred the study of memory and learning. Add that CCMenuItem to a CCMenu, and then add the menu as child of the layer: CCMenuItem itemTSCCLayer. Recall is a major part of the study of memory and often comes into play in all research. You don't have to add a menu item to it, but a menu. setPositionX (float x) Gets/Sets x or y coordinate individually for position. Gets position in a more efficient way, returns two number instead of a Vec2 object. For this reason, the main studies on memory in general will also provide a history to the study of recall. Sets the position (x,y) of the node in its parent's coordinate system. In 1885, Hermann Ebbinghaus created nonsense syllables, combinations of letters that do not follow grammatical rules and have no meaning, to test his own memory. He would memorize a list of nonsense syllables and then test his recall of that list over varying time periods.

Open up ActionLayer.mm and add the following code right after the +(id)scene method: So before we go any further, let’s give that a try and see what happens. There may be some of you out there that are thinking, “HUD?! I don’t need no stinking HUD! I’ll just add the labels directly to the layer!” Never fear – HUD to the rescue! Why You Need a HUD What’s worse – when you win or lose nothing happens except for a sound effect – there’s no way to retry! If you get hit by a laser as you play the game, you’ll notice that you take a hit – however there is nothing on the screen to show you your lives. Your goal is to avoid the lasers, and make it to the end! You’ll see this is a simple game where you tap to move, or double tap to jump. We create a variable named pMenu of the CCMenu type and add it to the layer: CCMenu pMenu CCMenu::create(pCloseItem, NULL) pMenu. If you’re curious, this game was made in this and that tutorial, but I don’t recommend those tutorials for beginners. Start by downloading the sample game that we will be using for this tutorial.

This tutorial is for beginners to Cocos2D who have gone through the How To Make a Simple Game with Cocos2D tutorial, or have equivalent knowledge. In this tutorial, we’re going to take a Cocos2D game that has been made with a single scene and single layer, and add a second layer to use as a HUD. You might want to use the HUD to contain extra controls (like a joystick or buttons) or you might want to use it to display status information (like lives or score).
A common question for beginners to Cocos2D is how to add a second layer to your scene to use as a Heads-Up Display, or HUD.
