控件不会进入我的xna代码中的update（）和Draw（）方法。 [英] Control is not going into the update() and Draw() methods in my xna code.

问题描述

我写了一个代码来更新XNA中某个骨骼的位置。



Mycode由三部分组成



第一部分是Loadcontent（）

I wrote a code to update the position of one of the bones in XNA.

Mycode consists of three parts

First part is Loadcontent()

firstmodel = Content.Load<Model>("Models\\second-sample-");
  worldtransforms = new Matrix[firstmodel.Bones.Count];
  originalbonetransforms = new Matrix[firstmodel.Bones.Count];
  bonetransforms = new Matrix[firstmodel.Bones.Count];
  firstmodel.CopyAbsoluteBoneTransformsTo(originalbonetransforms);
  firstmodel.CopyAbsoluteBoneTransformsTo(bonetransforms);
  aspectratio = graphics.GraphicsDevice.Viewport.AspectRatio;

第二部分包括更新骨骼位置和更新worldtransform。

更新。

Second part consists of just updating the position of the bone and updating in worldtransform.
Update.

bonetransforms[Index] =  originalbonetransforms[Index]* Matrix.CreateRotationX(50.5f) ;
worldtransforms[0] = bonetransforms[0];

           for (int bone = 1; bone < worldtransforms.Length; bone++)
           {
               int parentbone = firstmodel.Bones[bone].Parent.Index;
               worldtransforms[bone] = bonetransforms[bone] * worldtransforms[parentbone];
           }

，最后Draw（）方法和往常一样。



但控制直接进入

and finally Draw() method is as usual.

But control is directly going to

protected override void Initialize()
        {
            base.Initialize();
        }

我将所有方法都定义为受保护。

我的问题是，只要我运行代码控制从Lodecontent（）移动到Initialize（），模型显示在屏幕上，为什么它没有移动到Update（）

I defined all my methods as protected.
My question is that as soon as i run the code control moves from Lodecontent() to Initialize() and the model is displayed on screen, why it is not moving in to Update()

推荐答案

我认为你有提出了一个好的有效问题。但无论如何，对于这种思维错误，我总是首先尝试阅读文档（如果我使用特定技术（API），则更多）。



请查看 http://msdn.microsoft.com/ en-us / library / microsoft.xna.framework.game.update.aspx [ ^ ]



另请阅读有关Initialize和Draw的信息 - 我认为这很好在那里解释 - 以及调用方法的顺序（或间隔）（简而言之：不要指望在初始化阶段调用更新的beeing）。

I think you have formulated a good and valid question. But anyway, for this kind of "mind bugs" I'd always try to read the docu first (even more if I use a specific technology (API)).

so have a look at http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.game.update.aspx[^]

Read also about Initialize and Draw - I think it's well explained there - and the sequence (or interval) the methods get called (in short: don't count on Updated beeing called during initialization phase).
