pygame的“定时事件”功能

Question

I've never found a clear answer to how I could create a timed event in pygame,

I want to create a timed movement with duration and cooldown. (let's say 1s and 2s respectively for this example). Similar to an Evade or Dash skill in games

I've reedited the code and:

dash_now = 0
dash_cooldown = 2
    if dash:
        while dash_now < 2 and dash_cooldown >= 0:
            dash_now +- clock.tick(60) / 1000
            player.dash()
            firing == False
        else:
            dash = not dash
            dash_now ==  0
            dash_cooldown == 3
            dash_cooldown +- clock.tick(60) / 1000

Not working so far... I must be commiting a stupid mistake over here and I can't see which it is.

Answer 1

Its actually pretty simple:

Lets say you have a timer variable

timer = 0

After that, during every iteration, you add the time that has passed since the last frame:

timer += my_clock.tick(60) / 1000

Finally, later in the code, you can check if it meets a certain threshold.

if timer >= 2:
    # Insert whatever you want

    timer = 0

Therefore your code can be greatly simplified like this, as long as youre not expecting to be in a loop for the entirety of the movement.

self.dash_delay = 0
self.is_dashing = 0

def dash(self):
        if dash_delay < 0 and self.is_dashing < 2:

            self.rect.x += self.speedx * 2
            self.rect.y += self.speedy * 2
            self.is_dashing +- clock.tick(60) / 1000

        elif self.is_dashing > 2:
            self.dash_delay = 3
            self.is_dashing = 0

        self.dash_delay -= clock.tick(60) / 1000
