How to make a score multiplier with demo game

First, you will want to edit your player code with something like this:

on score_chain do
    if chain==0 then
        scorechain_bonus = 0
    end
    if chain>5 then
        scorechain_bonus = 1
    end
    if chain>10 then
        scorechain_bonus = 2
    end
    if chain>15 then
        scorechain_bonus = 3
    end
    if chain>25 then
        scorechain_bonus = 4
    end
    if chain>50 then
      scorechain_bonus = 5
    end
end

Then you want to create a item you can collect. I used the default disk item, so I didn't have to create anything, but add this code

on collect do
chain ++
tell event.player to
call "score_chain"
            if scorechain_bonus==0 then
                score += 1
            elseif scorechain_bonus==1 then
                score += 2
            elseif scorechain_bonus==2 then
                score += 4
            elseif scorechain_bonus==3 then
                score += 8
            elseif scorechain_bonus==4 then
                score += 16
            elseif scorechain_bonus==5 then
                score += 32
            end
        end
end

If you want the score to reset, you will also want to create a ground item. If you collect the item, you will want it to turn into the ground tile.

ground tile:

on collect do
    scorechain_bonus = 0
    chain = 0
end

Lastly, on the player code, add a draw event

on draw do
    label "Score:{score}" at 0,0
    if chain>5 then
        label "Score chain X {scorechain_bonus}" at 5,14
    else
    end
end

This is what you should get. I forgot to change Credits to score, because I was using code from another one of my projects:

I even made a demo game with some humor thrown in. Source code included. You are free to use the source code and/or learn from it.
