I found the Error. No Map was defined.

Just a quick note:
If you comment your code better and explain what it should do, it's easier for others to look through your code.

You might want to change your variable names to more descriptive ones too, no point in making it harder for yourself . The error you were most likely getting was too many draws at a time. Draws are much like texts, you write them but then you need to remove them before they go away, and if you are drawing 3 lines every frame you will most likely reach the limit(256 or 512) pretty soon. Plus, you might want to write your variables with write_int or write_float, as they update the values automatically, saves the trouble of writing them again every frame.
