Raid build: poster plus Scratch mini-game

A success list says what 'finished' looks like. The guild agrees it before anyone builds.

Each line must be something you can check: yes, it does that, or no, it does not.

1. The poster has one clear message.
2. Every image has a credit line.
3. The player moves with the arrow keys.
4. The game has a score and an ending.
5. The game tells the player one fact about the cause.
6. Another guild has tested the poster and the game.

Two people make the poster. Two people make the game. Both pairs follow the same success list.

The game pair uses decomposition: they break the game into parts, one job each.

Build the bin first and test it. Then the falling litter. Then the score, then the lives. Test after every part.

Here is the litter script once the score and lives parts are added:

when green flag clicked
go to x: (pick random (-200) to (200)) y: (170)
forever
    change y by (-5)
    if <touching (Bin v)?> then
        change [score v] by (1)
        go to x: (pick random (-200) to (200)) y: (170)
    end
    if <(y position) < (-170)> then
        change [lives v] by (-1)
        go to x: (pick random (-200) to (200)) y: (170)
    end
end

1. The litter starts at a random spot along the top.
2. Each time round the loop, it falls 5 steps.
3. Caught by the bin? Score goes up and the litter jumps back to the top.
4. Reached the bottom? Lives go down and the litter jumps back to the top.

A log is a short diary of the project. Write two or three lines at the end of each lesson.
