Making Pong in Pico 8

Hi everyone,

I made a couple of videos on making Pong in Pico 8 if anyone's interested.

As I mention in the video I don't consider this to be a tutorial really, since I'm new to Pico 8 and programming as a whole but it'd be great to get some feedback!

[Help] Powerup Code

Fri, 26 Jun 2020 17:08:56 UTC

Hi everyone, I'm fairly new to programming and Pico8.

I'm trying to add powerups to one of my games. I've made an empty table and a function to create each powerup within it.
The problem I'm having is that I'd like one single random powerup to be created depending on the score (say when score==5)

I've managed to do this but the problem was that a second powerup gets created before the player has the chance to up the score.
I've tried to use time() and also creating a boolean but I haven't managed to get 1 single powerup on screen at a time, I either get more than one or nothing.

What would be the best way to do this?

here's the code I have at the moment:

function _init()
    score=0
        powerups={}
end

function _update()
        if score==5 then
        powerup=true
    end

    if powerup==true then
        create_powerup()    
    end
end

function _draw()
         for capsule in all(powerups) do
        spr(capsule.sp,capsule.x,capsule.y)
    end
end

--powerups

powerups_start=5
total_powerups=4
fall=1

function create_powerup()   
    capsule={
    sp=powerups_start+flr(rnd(total_powerups)),
    x=flr(rnd(100)+20),
    y=flr(rnd(10))+20
    }
    add(powerups,capsule)

    powerup=false

    if powerup==false then
        del(powerups,capsule)
    end                         
end

function update_powerup()
    for capsule in all(powerups) do
        capsule.y+=fall

        if capsule.x>=player.x and
                    capsule.x<=player.x+player.w and
                    capsule.y==player.y-player.h then
                        sfx(2)
                     lives.left+=1
                     del(powerups,capsule)
        end 

        if capsule.y>128 then
            del(powerups,capsule)
        end 
    end
end

Thanks in advance!
