Character movement

1 Walking animation

2 Follow mouse

3 Keyboard controls (up down left right arrow keys)

For a maze: change each one like this:

(If it bmps into the wall, it bounces back in the opposite direction)  Same idea works for other movelment controls.

4 Keyboard controls (left-right)

5 Keyboard controls (forward and steer)

6 Jump

7 Gravity and platforms

Baddies

8 Follow a set path

Drag the sprite to each point before you choose each block

13 Random falling ovjects

 

14 Randomly timed objects

9 Sprite reacts to another sprite

I’ve made mine hide, but you could go bck to start, lose a life, score a point…

Next level/ game over

10 Door to next level

 

11 Game over

Coins / points / lives

Challenges

1. Theme your project for a game called “Blackout” bu changing costumes and backgrounds.
2. Come up with an idea for a game about the blackout – think of the sim, what characters and backgrounds you will need, controls, 1 player/2 player, lives, coins, levels, points, whether it is timed,

1 Work on game

1 Work on game

1. Work on your own or as a team – everyone needs to be actively coding and contributing.
2. Create all sprites (characters, buttons, doors, objects) and backgrounds that you need – even if they are just sketches
3. Choose which Scratch game toolkit blocks you need for your game.
4. Adapt them to change timings, actions, triggers to suit your game.
   1. Movement of main character
   2. Movement of enemies/other characters
   3. Reaction to other sprites – enemies, doors, coins
      1. new background, respawn, hide,…
      2. Make sure these reverrt back “when green flag clicked”, eg “show”
   4. Scores, lives, timers
   5. Game complete/over
5. Variables – if you have lives, score, timer…create variables for these. Remember to set them at the beginning (when green flag clicked) then change them when something happens.

Success: I have –

• Chosen blocks of code to make my game happen
• Created all sprites and backgrounds needed
• Read code to check what I’ve told it to do

2 Try each other’s games

• Compliment
