pygame-text | Convenience functions | Graphics library

Well sometimes we can say it is not possible, but often times it is just not the main goal of that package. Nonetheless, let's see if we can solve the problem.

I am taking the liberty of assuming that other packages besides pygame are allowed, but that the end result should be visible in pygame. In order to create the blooming / glowing effect I use the packages opencv-python (cv2) and numpy (np).

The first part of the solution will talk about creating a glowing border and some glowing text. The second part will talk about how this can be rendered upon a pygame surface.

TL;DR; Skip to the Summary part below and copy the code in their respective files.

In order to get some nice glowing borders and text, we can use the blurring functionality of opencv, which is also called smoothing. Since we want to create varying intensity of glowing, we first apply the GaussianBlur, to create some random blurriness around the image, and then extend that blurriness with the normal blur.

Your third problem (truncated pickle data) is because you are using TCP, and you are unpickling whatever recv returns. You might be thinking that whenever you send something, and the receiver calls recv, returns the exact same thing, but actually it doesn't. TCP splits your data up into packets, so the receiver might not receive all the data at the same time.

For example, if you send "abcdefgh" and then separately send "ijkl", it's allowed for the first receive to return "abcd" and the second to return "efghijkl". Or the first one could return "ab" and the second one could return "cde" and the third one could return "fghijkl", or so on.

You have to design a way for the receiver to know when to stop receiving. For example, if you sent "8abcdefgh" and then "4ijkl", the receiver could get "8abcdefgh4ij", and then it knows "8abcdefgh" is one "send" (because it starts with 8 and then 8 more bytes) and it knows the "4ij" is the beginning of the next "send" but it's not the whole thing (because it starts with 4 but there aren't 4 more bytes).

Another way is to send a special character like a newline (enter key) after each message. This probably doesn't work with pickles because pickles can have newlines in them. But you could choose another byte that pickles don't have, like 0xFF. Then the receiver knows to keep on receiving until it sees the byte 0xFF.

Follow the traceback: in your file Doge those cars.py line 90, that is in the func play() there is a line that states self.text = font.render("text that should appear", True, (238, 58, 140)) but it isn't in your class, and there is no 'self' defined.
