Stage 7 tasks

Work through the steps in order. If something breaks, compare your blocks to the video.

Video 2 — Time 05:35Open at 05:35 ↗
How to use the videos (do this every stage):

You cannot watch the whole video and remember every step. Instead: watch ~30 seconds, pause, then build that section in Scratch. Repeat.

  • Split your screen so you can see Scratch and the video at the same time.
  • Windows: open Scratch and the worksheet/video, then press Windows key + Left Arrow to snap one app to the left. Click the other window to fill the right.
  • If you want Scratch bigger: drag the divider so Scratch takes about 2/3 of the screen and the video takes 1/3.

Create and set health

  • Variables → make health.
  • On Main: set health to 100 and score to 0 when green flag clicked.

Win condition (timer reaches 0)

  • In timer loop: if time remaining = 0 then switch backdrop survived, broadcast survived, stop this script.

Lose condition (health reaches 0)

  • On Main: if health = 0 then broadcast dead and stop other scripts in this sprite.

Make Buddy deal damage

  • On Buddy: if touching Main → change health by -1.
  • Optional: add a tiny wait to avoid instant death.

Clones: swarms of enemies

  • On Buddy: wait 3 seconds → create clone → go to random position.
  • When I start as a clone: wait 3 seconds → create clone.
  • Make sure clones also chase and deal damage.

Randomise enemy speed

  • Replace move 7 steps with move pick random 3 to 7 steps.

Hide Buddy when dead/survived

  • When I receive dead → hide
  • When I receive survived → hide
  • When I receive start → show
Quick check (it works if…)
  • Health starts at 100 and goes down when enemies touch you.
  • At 0 health you see the dead screen.
  • At 0 time remaining you see the survived screen.
  • Enemies multiply over time (clones).
Extension:
  • Add a proper health bar sprite (challenge).
  • Hide the health variable display so only the health bar shows.

Scratch tips for this stage:
  • If you die instantly, add a tiny wait 0.1 after taking damage (optional).
  • Clones need their own script: when I start as a clone — otherwise they won’t multiply properly.
  • Randomise enemy speed with pick random so swarms don’t clump into one blob.
