好的，我想为我的GUI制作2d地图（游戏的文字地图）。在游戏中，我将地形数据导出到一个外部lua文件中，该文件如下所示：Info = {{1 = {颜色=“蓝色”，x = 0，y = 0}，等等...}大数组。我的gui读取此文件并wxDrawcircle并将像素大小的彩色点放置在坐标上。这一切都可以，并且创建了一个漂亮的地图，但是问题是当我单击或执行任何操作时，它都冻结了，看起来GUI无法处理所有这些点。几乎就像我每次单击GUI一样，刷新并重新渲染所有这些点。因此，我的问题是我应该制作纹理，还是我的GUI有一种方法可以一次又一次地渲染地图，而不是像刷新自身一样一遍又一遍？
更新：感谢您的反馈，他们确实提高了加载速度。但是我添加了if canrun then，所以它只能运行一次，因为我发现每次移动滚轮时，它都会重新生成整个地图，从而导致崩溃。因此，如果有一种解决方法可以防止在向上或向下滚动时地图消失，那么这将起作用。
我的GUI。更新

您可以改进几件事：
dc。这是非常低效的，因为您只需要在循环之前创建一次即可（实际上，您可以这样做，但不要使用它）。dc相同；循环后只做一次DrawPoint呢？所以我的问题是我应该改用一个纹理，还是我的GUI有一种方法可以一次渲染地图，而不是像刷新自身一样一遍又一遍地渲染地图？
是的，您可以将要绘制的内容保存到位图，然后绘制位图本身，而无需花费时间绘制其组件。您的OnPaint处理程序将如下所示：
local function onPaint()
local dc = wx.wxPaintDC(frame)
dc:DrawBitmap(bitmap, 0, 0, true)
dc:delete()
end
您的绘图将在需要时在bitmap上绘图：
mdc:SelectObject(bitmap)
mdc:SetPen(WHATEVER)
mdc:DrawPoint(x, y)
mdc:SelectObject(wx.wxNullBitmap)
其中mdc=wx.wxMemoryDC()。
