Re: [pygame] Sluggish movement

[Jake b <ninmonkeys@xxxxxxxxx>]

You can do time independant movement:

xvel_per_frame = elapsed * xvel_per_second

yvel_per_frame = elapsed * yvel_per_second

So in your update() function:

def update(self):

self.last = self.now

self.now = pygame.time.get_ticks()

self.elapsed = (self.now - self.last) / 1000.

In your unit movement code:

self.loc += self.vel * game.elapsed

so i wrote this program, but the bullets coming out of the player's ship move at an irregular speed, first fast, then slow, then fast again... but they're supposed to move at a regular 12 pixels per frame. What am i doing wrong?
