1. Street Racing Game

2. Create the opening screen

3. 相信大家在之前的練習中已學會了如何加入圖片、聲音及背景等素材。

4. Create the room and set the background image.

5. Set the vertical speed to 3, therefore the background will move down slowly at a speed 3.

6. Create the controller_start to control the object in the room0.

7. Set the probability to generate a car_down is 1/50

9. Similarly, set the probability to generate a car_up is 1/100

11. Left click the mouse to add the controller_start in room0.
You can preview the game now!!!

12. Add an event to start the game by pressing any key

13. Set the transition style as you want.

14. Set the background music at the “Game Start” Event
Add event  other  Game Start
Play sound!!!

16. Under the “Game Start”
Set the “New score” = 0

17. New lives = 3

18. Add some instruction for the user
Add Event  Draw

19. Select the Font and alignment

20. Select the Colour

21. Add the Text and the position as you want

22. Similarly, add the second row of text.

26. SET the Object: car_down

27. Reset the variable “dead” to “false”

28. As there are four kind of car, we set the game to generate the car randomly among the four.

29. Use the “Jump to start” the set a car created in lane 3
Set the vertical speed is 6

30. Set the car created at lane 3 with a chance 1/2

31. Preview

32. Start a block

33. Similarly, Set the Use the “Jump to start” the set a car created in lane 2
Set the vertical speed is 5

34. Set the car created at lane 3 with a chance 1/3
Similarly, Set the Use the “Jump to start” the set a car created in lane 2
Set the vertical speed is 5

35. When the car go outside the room

36. If the car y position of the car > room_height

37. Destroy the instance

38. Overlap

39. Check object Overlap

41. car_up x = 44+300 speed = 2 x = 44+240 speed = 1 x = 44+180
Similarly, Set the car_up

42. Complete the opening room
End of Lesson 1

43. Lesson 2
Create the Room 1

44. Create the required “Object”

45. Create Object: controller
It is used to control the generation of car_up, car_down, police car, petrol, score and lives.

46. Set the variable name and value as global.petrol and 1000.

47. Set the Alarm0 as 300.

48. Alarm0 is used to generate the petrol in the game.
Add Event  Alarm  Alarm0

49. Main1  Create  Object  Gas
X  40+random(320)
Y  -40

50. Main2  Create  Set Alarm  Number of Steps : 300+score/100

51. Add Event  Step  Score  new score  1 (relative)

52. Then Set the step as below:
car_down
car_up
Police car

53. When there is no more lives :
Show the Highscore table
2. Restart the Game

54. Draw the score caption :
Lives (Cars left)
3. Petrol

55. Draw the petrol left box

57. 480+max(0,min(100,global.petrol/10))

58. Create car_racing

59. Set the variable “dead “ as “false”

60. Set the vertical speed as 0

63. What happen after “Crash”
Racing car

66. Similarly for the car_up

67. Create the Room 1

70. What happen after “Crash”
car_down, car_up
and police car

76. Control the racing car to move
Left

78. global.petrol > 0 && x >32 && not dead

80. Left: global.petrol > 0 && x >32 && not dead
Right: global.petrol > 0 && x < 360 && not dead
Up: global.petrol > 0 && not dead
Down: global.petrol > 0 && not dead
Left: x = -2, y=0
Right: x = 2, y=0
Up: x = 0, y=-3
Down: x = 0, y=3

84. End of Lesson 2

85. When the racing car get the petrol

88. Create petrol

89. Set the speed of petrol as the background = 3

90. If the y position of the petrol as the height, destroy the instance.

91. Go back to the setting of the racing_car.

93. Create the police car

95. 1. Sound = sirens, loop =true
2. Variable “dead” = false
3. Vertical speed = -1.5
4. X  car_racing.x
Y  room_height
5. Check object ”racing car”
6. Destroy the instance
7. Check object ”racing car”
8. Destroy the instance
9. Check object ”racing car”
10. Destroy the instance

97. If dead = true
2. Exit
3. If “car_racing.x<x && place_empty(x-8,y)”
4. Jump to left (-2) relatively
If “car_racing.x>x && place_empty(x+8,y)”
6. Jump to right (2) relatively

98. Similar to car_down and racing_car.
Vertical speed =3
Similar to car_down and racing_car.

99. y<0 || y > room_height+20

100. Completed!!

101. End of the Game

102. Additional tasks Add hearts to increase the lives
