void TE::Render::APIVertexBufferLayout::Enable()
{
if (m_hasPosition)
{
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, m_positionValueCount, m_positionValueType, GL_F ALSE, m_stride, (void*)m_positionOffset);
}
if (m_hasNormals)
{
glEnableVertexAttribArray(1);
glVertexAttribPointer(1, m_normalValueCount, m_normalValueType, GL_FALSE, 0, ( void*)m_normalOffset);
}
for(unsigned i = 0; i < m_textureCount; ++i)
{
glEnableVertexAttribArray(2+i);
glVertexAttribPointer(2+i, m_textureValueCount[i], m_textureValueType[i], GL_FALSE, m_stride, (void*)m_textureOffset[i]);
}
}
我在调用glEnableVertexAttribArray（0）时遇到访问冲突，在与#openg irc频道中的某个人交谈后，我的堆似乎已损坏。
所以我启用了带有应用程序验证程序的完整页面头，并通过debuger启动了我的应用程序（visual studio 2012）：

当我启动应用程序时，visual studio在下面的函数中显示m_apiVertexBuffers [＆amp; mesh] - ＆gt; Enable（）行上的断点..但是这是我之前得到断点的实际值之后.. m_apiVertexBufferLayouts [＆amp; mesh] - ＆gt; Enable（）是上面粘贴中对函数的调用，所以它在那里打破..
void TE::Render::Renderer::Enable( const Mesh& mesh )
{
assert(m_apiVertexBufferLayouts.find(&mesh) != m_apiVertexBufferLayouts.end() && "VertexBufferLayout not loaded");
assert(m_apiVertexBuffers.find(&mesh) != m_apiVertexBuffers.end() && "VertexBuffer not loaded");
assert(m_apiIndexBuffers.find(&mesh) != m_apiIndexBuffers.end() && "IndexBuffer not loaded");
m_apiVertexBufferLayouts[&mesh]->Enable();
m_apiVertexBuffers[&mesh]->Enable();
m_apiIndexBuffers[&mesh]->Enable();
}
如何进一步调试？这是我第一次使用调试器，所以我很困惑..
