XNA 4.0应用程序突然关闭当它击中的方法没有抛出任何异常 [英] XNA 4.0 app closes suddenly when it hits a method without throwing any exceptions

问题描述

正如标题所说，我有一个XNA应用程序，突然关闭，当它击中的应用程序，但不显示任何错误，所以我没有线索如何甚至开始调试它做。代码很简单 - 我只是用XNA玩，并试图呈现一个简单的三角形 - 所以我不能想象为什么它停止。该公司正在运行的代码是

As the title says, I have an XNA app that closes suddenly when it hits an app, but doesn't show any errors so I don't have a clue how to even begin to debug it. The code is very simple - I'm just playing with XNA and trying to render a simple triangle - so I can't imagine why it's stopping. The code that's running is

    VertexPositionColor[] vertices;

    public Terrain()
    {
        vertices = new VertexPositionColor[3];
        vertices[0].Position = new Vector3(-0.5f, -0.5f, 0f);
        vertices[0].Color = Color.Red;
        vertices[1].Position = new Vector3(0, 0.5f, 0f);
        vertices[1].Color = Color.Green;
        vertices[2].Position = new Vector3(0.5f, -0.5f, 0f);
        vertices[2].Color = Color.Yellow;
    }

    public void Draw(GameTime gameTime)
    {
        ScreenManager.GraphicsDevice.DrawUserPrimitives<VertexPositionColor>(
            PrimitiveType.TriangleList,
            vertices,
            0,
            1,
            VertexPositionColor.VertexDeclaration);
    }

和它的Draw（）函数的螺丝它。当我删除DrawUserPrimitives线运行良好（虽然什么都不显示...）

and it's the Draw() function that screws it up. When I remove the DrawUserPrimitives line it runs fine (although show nothing...)

推荐答案

我将假设屏幕管理'是继承了一个类的DrawableGameComponent'，你是从那里访​​问图形设备？使你的游戏类你初始化的GraphicsDeviceManager（本）的构造肯定的地方。

I'm going to assume that 'ScreenManager' is a class that inherits off 'DrawableGameComponent' and you are accessing the graphics device from there? Make sure somewhere in the constructor of your Game class you are initialising the GraphicsDeviceManager(this).

我认为这是'GraphicsDevice的你的ScreenManager是抓住了静态可能未正确初始化。

I think it's the 'GraphicsDevice' that your ScreenManager is grabbing statically that might not be initialised properly.
