#40382 — Pygame mouse cursor load/unload

I am in the process of making a pong game in python using the pygame library.  My current problem is that when I move the mouse, it turns off as soon as the mouse stops moving.  The way I am doing this is by making the default cursor invisible and using .png files as replacements for the cursor.  Perhaps my code would best explain my problem.  I will take help in any way that I can.  Here are the links that contain my code:

Main class:  http://pastebin.com/HSQzX6h2
Main file (where the problem lies):  http://pastebin.com/67p97RsJ

If the links yield nothing, please let me know (agardner210@gmail.com)

Your mouse motion code draws the paddle in the new position, waits
1/10th of a second, and then draws over it again with the "invisible"
paddle.  Thus, approximately 1/10th of a second after you stop moving
the mouse, it disappears.

Mouse motion events are probably not the best way to do this.  You can
instead just capture the current position of the mouse on every frame
and use that instead.  I replaced your main loop with the following:

paddle_pos = (0, 0)
clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()

    # Erase the paddle from the old mouse position.
    screen.blit(bpaddle, paddle_pos)
    # Redraw the net before the paddle so that the paddle can appear over it.
    pygame.draw.line(screen, game.lineColor, game.net1, game.net2,
                     game.netWidth)
    # Get the new mouse position.
    paddle_pos = pygame.mouse.get_pos()
    # Draw the paddle at the new mouse position.
    screen.blit(beeper, paddle_pos)
    # Update the screen if it's double-buffered.
    pygame.display.update()
    # Finally, let the CPU idle until it's time for the next frame.
    # 50 here means that it will sleep long enough to achieve 50 FPS.
    clock.tick(50)

And I think you will find that this does what you want.

A couple more observations while I'm at it.  Generally there is no
need to be calling pygame.display.update() multiple times per frame.
Just draw everything that you need, and then call it once at the end
of the loop, as I have shown above.  Also, the shebang line only does
anything if it's the very first line in the file, so it would need to
appear before the module docstring to do anything useful.

Thank you very much, Ian.  I understand the code and have learned from it.  If I were more knowledgeable in python I wouldn't have had to ask; I am learning as I go with this project.  Again, thank you :)

I have a new problem :(.  I want to restrict the paddle to a certain plane.  I have it working but when the paddle reaches the limit it locks up.  I have no idea how I can redraw it back in the plane.  I am using the code that Ian provided (thank you so much).  I was thinking of making an else to redraw the paddle using the same code, but part of me thinks that it would be rather sloppy.

    if (0,0) <= paddle_pos <= (300,300):
         paddle_pos = pygame.mouse.get_pos() 
         screen.blit(beeper, paddle_pos)
         pygame.display.update()
         clock.tick(50)

I have a new problem that I'm dealing with.  I want to restrict the paddle to a certain plane.  When the paddle reaches the boundary, it locks up.  I am using the code that Ian provided earlier (thank you so much).  Here is what I have so far:

    if (0,0) <= paddle_pos <= (300,300):
         paddle_pos = pygame.mouse.get_pos() 
         screen.blit(beeper, paddle_pos)
         pygame.display.update()
         clock.tick(50)

I tried making an else statement and copying Ian's code in it, but I don't think that it would work.  I have tried to fix this myself; this is my second GUI program that I have ever made.... please forgive me if I seem needy.

This doesn't do what you think it does.  Tuples are compared
lexicographically, not element-wise.  So (250, 350) < (300, 300), but
(350, 250) > (300, 300).

You're updating paddle_pos inside the if block.  Once paddle_pos falls
outside that range, the if block won't trigger, and paddle_pos will no
longer be updated, so it will never fall inside that range again.

pygame has a Rect class for rectangle logic that can solve both of
these problems for you.  Given:

paddle_rect = beeper.get_rect()
bounds_rect = pygame.Rect(0, 0, 300, 300)

your position update code then becomes:

paddle_rect.center = pygame.mouse.get_pos()
paddle_rect.clamp_ip(bounds_rect)

Note that paddle_rect can replace paddle_pos entirely.  The code:

screen.blit(beeper, paddle_pos)

simply becomes:

screen.blit(beeper, paddle_rect)

I followed your advice, but now I have a drawing problem.  I simply tried rewriting the paddle with a black one, but its failing.  I would like to pester you fine folks one last time.  The code is here:  http://pastebin.com/gVPPJYWs

I really appreciate your help and am learning from your advice.

Thank you so much, Alex

I would like to bother you fine folks one last time!  There are drawing problems that I am running into.  The paddle keeps on moving but it doesn't rewrite the black paddle.  This is a problem because the paddle just keeps leaving a green trail.  The code is here:  http://pastebin.com/gVPPJYWs

I feel as though I am missing something...

You get the streaking because the first blanking operation only ever
blanks at (0, 0), and the second one blanks at the new paddle
position, not the previous position.

You don't need two separate rects to keep track of where the paddle
is.  blank_rect and b_bounds_rect are entirely unnecessary, so get rid
of them.

The line "screen.blit(bpaddle, paddle_pos)" should be replaced with
"screen.blit(bpaddle, paddle_rect)", because paddle_rect is what
you're using to track the paddle location.  Since paddle_pos is not
being updated, the former would always draw the blank paddle in the
upper-left corner.  This should also be the only place where you're
blanking the paddle, so get rid of the other one.

You also don't need the if statement at all.  The clamping operation
already ensures that the paddle is bounded to the region (0, 0, 300,
300).

Once that's gone, you no longer need paddle_pos at all, so you can
delete that as well.

Now the cursor isn't moving at all!

while True:
	for event in pygame.event.get():
		if event.type == QUIT:
			sys.exit()

	screen.blit(bpaddle, paddle_rect)
	# Draw the net
	pygame.draw.line(screen, game.lineColor, game.net1, game.net2, game.netWidth)

	paddle_rect.clamp_ip(bounds_rect)
	screen.blit(beeper, paddle_rect)

	clock.tick(50)

	pygame.display.update()

You deleted the line where you update the paddle_rect from the current
mouse position.

We're not psychic, so you'll need to post the current code if you want
any suggestions on how to fix it.

You're still drawing the blank paddle in two different places.  One of
those places is immediately after you draw the paddle, which undoes
the work you just did in drawing it.  That's why you're not seeing the
paddle.

You're also still not updating the paddle_rect from the current mouse
position, so if you fix the above issue you will find that the paddle
still will not move.  You should restore the "paddle_rect.center =
pygame.mouse.get_pos()" line that you deleted prior to the line that
clamps it.

Finally, you currently have the "clock.tick()" call before the
"pygame.display.update()" call, which makes no sense.  You're doing
your drawing, asking pygame to sleep for 20 milliseconds, and only
then updating the display.  You want to update the display before the
clock.tick() so that the user can actually see the most recent frame
during those 20 milliseconds.

I tried to append what you told me to.  Now it appears that I have a syntax error!  I checked my indentations and they look fine to me, but I get this error:

    paddle_pos = pygame.mouse.get_pos()
                                      ^
IndentationError: unindent does not match any outer indentation level

I added "paddle_rect.center = pygame.mouse.get_pos()" and removed the double blank paddles.  I have no idea if it works though because of the parse error!  New code:  http://pastebin.com/maqWCdNB

It's complaining because the preceding 'for' loop is indented more that
that line.
