The X in XNA represents a powerful software tool that can reach cross-platform across Windows Xbox and partners. N means "next generation (Next-generation)", and a means "schema (architecture)". XNA is a game development environment based on DirectX, a revised and expanded version of Microsoft for Managed DirectX. Its mission is to help developers reduce costs when creating better, faster and cross-platform games. By consolidating Microsoft's best innovation and the industry's best innovation fo

In the 2.x processing of events need to use the principal agent (delegate), I believe that the learning of the 2.x touch events, students know that the creation and removal of the process is very cumbersome. In 3.x, because of the addition of the c++11 feature, the distribution mechanism of the event is managed through the event distributor Eventdispatcher. The main event listeners are: > Touch events: Eventlistenertouchonebyone, eventlistenertouchallatonce > Mouse Response Event: Eventlistenerm

Overview Hardware on the use of stm32f4+mpu9150 implementation of the neural network recognition gesture, but not with the IMU geomagnetic data, only with the three-axis accelerometer and three-axis gyroscope data, the board is the main reference to the Italian official Development Board schematic diagram (Life painting the first board has not been wrong ha, Let's have a little bit more fun ... ）。 MPU9150 drive is used by the InvenSense to provide EM

Explanation of several angles Euler angle:http://baike.baidu.com/link?url= Vajuhz-luawv7zua-67dibb0jjwyyqqnwnqeejdrcomwdt1xrtjgq2anyojngfrkfoo3t_1gcwpebbgp3npfzq With Euler's angle, you can determine the following, roll angle, pitch angle, and yaw angle . In general, the right, front and top three directions of the carrier are formed right-hand system, the axis around the forward rotation is the roll angle , rotation around the right axis is the pitch angle , the axis around the upward

structure that forms the UI layout of the entire game. The following is a brief introduction to the UI System module: Window Layout group: The same feature UI build merged into one layout layouts, unified management: Initialization/load/update/event response/unload operation; Based on the processing mode of message event, it is convenient to expand the script. Use external configuration to process/support dynamic configuration. Independent root window (uilayer): The bottom of the System window

has a significant performance boost over the Vaio duo 11 core i5-3317u. In particular, the difference between the two in the video card test is more obvious: in the 3dmark06 test, Duo 13 scored 6047, whereas his predecessor was only 4807. The former results also beat the Ivy Bridge platform for the best results-the Acer Aspire S7 scored 4918 points. And for overall performance, like the PCMark7 test, we're not seeing that much improvement-in fact, the duo 13 scored even slightly below the duo

emulator), can not play and accept the phone, and can not send and receive text messages. No GPS simulator can automatically generate the GPS simulation data. The simulation data for the Gravity Accelerator (accelerometer) simulator are not updated and remain as matrices (0, 0,-1), indicating that the simulator has not been moved. Cannot simulate a built-in lens. The emulator does not contain a WebBrowser control. This can be done and can not do

application, and this control can appear on the level of detail, which exposes a large number of functional details, users can determine the use of the application needs to display what features. In many cases, when the user is familiar with the application and its complex operations, it is natural to explore more control in the application, simplifying its own process.Think: Today, many apps appear to be customized to meet the user's control requirements. Users can simplify their own operation

. CCScene: Scenario The scenario does not have any special functions. It serves as a layer container and process control. 3. CCLayer: Layer void addChild（CCNode* child）；void addChild（CCNode* child，int zOrder）；void addChild（CCNode* child，int zOrder，int tag）；Child is the added node. For a scenario, a node is a layer. to specify the order, different zOrder values can be used. zOrder represents the order of elements under the node, the larger the value, the closer the display order is, the default v
