Re: [pygame] Continuous Shooting
Yeah.. I applied the counter logic and it worked for me :) Thanks a lot :)

Re: [pygame] Continuous Shooting
First off, you need some sort of time management. As it is now, it'll run at
variable speeds depending on how fast the processor is. Use pygame.time.Clock
to limit the frame rate and/or use delta timing.
As for your problem, all you need is a counter variable. Have the counter
variable start at 0 and decrease it by 1 (or the amount of time passed if
you're using delta timing) each time the loop happens. When the shoot key is
pressed, create a bullet and set the counter to the amount of time you want to
wait for the next bullet. Then, if the shoot key is held down while the loop
variable is 0, create another bullet and reset the counter to the wait time.

HeyI was making a demo shooting game and problem is that I want
a continuous stream of bullets. As of now on pressing the space key only one
bullet comes out of the plane (I want this to be continuous stream). On
pressing space key again bullet starts from its initial point. My problem in
the code is that I am able to make a single object of Bullet only (thats why it
is throwing single bullet) and unable to find the another logic. Please help me

[pygame] Continuous Shooting
Hey
I was making a demo shooting game and problem is that I want
a continuous stream of bullets. As of now on pressing the space key only
one bullet comes out of the plane (I want this to be continuous stream). On
pressing space key again bullet starts from its initial point. My problem
in the code is that I am able to make a single object of Bullet only (thats
why it is throwing single bullet) and unable to find the another logic.
Please help me out. Attaching the files along with this mail.
