gametime united

Well, the first blog post in the blog Garden (I ordered a blog post to import wordpress. There is no news here =) Let's first introduce the background. I used Pygame to write a semi-finished game in Python. I felt that the weak type of Python caused a problem in the expansion of the Code Scale (in fact, it was impossible to be lazy without automation ~) I have a book about XNA, so I plan to migrate it to XNA. XNA should have been abandoned. Now we can only find XNA Game Studio 4 and only suppor

Just a friend asked me how to implement the jump. In fact, I don't know about xna either. In Zzk, there is no matching record for searching "XNA jump". I was a little impulsive when I was surprised. Do I have to do it myself? But xna really doesn't understand it. I found two or three source codes, and I was really stupid. I was so sorry to understand its algorithm. Simply implement it from the ground up by yourself. The reason to consider taking off from reality is the Take-off Speed (v1) weight

tutorial, it stores the ball in the tag attribute of the model. This tag attribute can store any object of the model and is suitable for storing the sphere of the model. Use the following in the loadcontent method:Code: Mymodel = xnautils. loadmodelwithboundingsphere (ref modeltransforms, "tiny", content ); Collision Detection is required for both mobile cameras and models. If a collision is detected, you will cancel the last change of the camera by restoring the camera position to the init

converts the data to the gamedata object: Private void loadgame (storagedevice) {storagecontainer Container = storagedevice. opencontainer ("bookcodewin"); string filename = path. combine (container. path, "save0001.sav"); If (file. exists (filename) {filestream SaveFile = file. open (filename, filemode. open); xmlserializer = new xmlserializer (typeof (gamedata); gamedata = (gamedata) xmlserializer. deserialize (SaveFile); SaveFile. close ();}} Code The update method checks whether the user

void Initialize(){int centerX = Game.Window.ClientBounds.Width / 2;int centerY = Game.Window.ClientBounds.Height / 2;//Mouse.SetPosition(centerX, centerY);//base.Initialize();} OK, we 've set the basis. only two more methods to implement. in the loadgraphicscontent method we'll calculate our projection. in the update method, we'll calculate our view. first the projection:protected override void LoadGraphicsContent(bool loadAllContent){float ratio = (float)GraphicsDevice.Viewport.Width / (float)

Only two more methods to implement. In the Loadgraphicscontent method we'll calculate our projection. In the Update method, we'll calculate our view. The projection:protected override void Loadgraphicscontent (bool loadallcontent){float ratio = (float) GraphicsDevice.Viewport.Width/(float) GraphicsDevice.Viewport.Height;Proj

frame.For example the game runs very fast and the update is called every 20 milliseconds and we need to update the frame every 200 ms, then the progression of the frame will happen at every 10th game update. Here's the code: 01 public void update(long gameTime) { 02 if (gameTime > frameTicker + framePeriod) { 03 frameTicker = gameTime; 04

the coordinates of a model file consisting of a large number of triangles to our own coordinate system? The image of the skeleton is used here. There is bone data in the 3D model file, just like the human skeleton, as long as the skeleton is determined, the coordinates of the associated part attached to the skeleton are determined. If the coordinate of the skeleton is transformed, the associated part is also transformed. Therefore, before creating a model, a matrix array is required to store th

view matrix and projection matrix of skybox as the camera parameters: camera = new Camera(this, new Vector3(100,100,100), new Vector3(0, 0, -1), Vector3.Up, MathHelper.PiOver4, GraphicsDevice.Viewport.AspectRatio, 0.1f, 500); skyBox.projectionMatrix = camera.projection; skyBox.viewMatrix = Matrix.CreateWorld(new Vector3(0,0,0),new Vector3(0,0,-1),Vector3.Up); Finally, in order to see the effect, add the following code to update: protected override vo

After reading the xNa practical keyboard article-moving an image based on the arrow key (3), do you still feel a bit confused? Let's see how xNa handles mouse events, save the previous experiments. Let's create a new project named "mysecondgame". This time we will not give allCodeI have read the previousArticleIt is clear. Define the "global variables" in the class ": /// /// Image Position/// Private vector2 picposition;/// /// Define a 2D Texture Image/// Private texture2d texture;

compilation can not go through. The first XNA program Hello World! 1. Create an XNA project, add the spritefont font file to the Content project, and configure the font to be used. Add the code to the Game1.cs file: Protected override void Draw (GameTime gameTime) { Base. Draw (gameTime ); SpriteBatch. Begin (); SpriteBatch. DrawString (Font, "Hello World !",

draw the target sprite. By default, SpriteBatch determines the relative value of layer depth according to the order in which you call it, for example, you first call SpriteBatch to draw Sprite A, and then call SpriteBatch in the same place to draw Sprite B, then, Sprite B will block Sprite a. If we rely on the order in which the spritebatch is drawn to determine the depth of the sprite, then it is too inflexible, and to do so, when invoking the SpriteBatch rendering method, you can specify a pa
