This isn't so much of a Python issue as a Django issue - there are many ways in Python (and indeed most languages) of watching for a time to pass, but the problem is how you act upon it. …

The general process here is simply something like this: for row_number in rows: for column_number in columns: value = data[column,row] if value == 1: obj = ObjectType1() elif valu …

Generally speaking it isn't possible to do real-time per-pixel masking with software renderers if performance is a concern. So you need to do the processing offline. I don't understand the task you a …

If your tiles are rectangular, and if you make your tiles a 2D structure rather than a 1D structure then you can deduce the boundaries in world coordinates from the tile's position in 'tile coordinate …

When you embed Python into C++, you just have to set up the code to call the Python functions in C++. … The Python libraries that you use, such as Pygame, have no effect on the C++ binding code you need to use. …

There is no 'proper' way, just different approaches that vary from simple-but-slow to complex-but-fast. You can stick with that method, if your car list is small enough. However, there is a bug in yo …

For a rectangular selection, it would be a lot like your existing code. def mouseDown(self, button, pos): self.selection_rectangle_start = self.coord_convert(pos) def mouseMotion(self, pos): …

Load everything at the start. Don't complicate your program by splitting data between memory and disk unless you have to (eg. when there is too much to hold in memory at once). The important thing is …

You're using Python, so you should use a dict for this, mapping unique values to each item, letting you remove items without affecting the positions of others. …

In addition to what Adam has already said in his answer (and especially the second paragraph), it's worth noting that Python does not scale well with threads at all, because there is a global lock shared … across all Python threads so that only one can run at a time, except under certain conditions. …

Interesting. My guess is that the Convert call is changing the image into a form that does not have the 255,0,255 colour in it any more. You may need to read a pixel from the converted image which you …

In Python, that usually means pyglet, but you can roll your own using pyopengl. …

You accomplish the scrolling by moving the camera, and calculating the screen position for a tile based on the current camera position. You can skip drawing of any tiles that are not on screen. def d …
