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!

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!
