Street Racing Game

Create the opening screen

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。 由於時間關係，我們直接開啟我們範本。 \\schoolpublic\…..

Create the room and set the background image.

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

Create the controller_start to control the object in the room0.

Set the probability to generate a car_down is 1/50

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

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

Add an event to start the game by pressing any key

Set the transition style as you want.

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

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

New lives = 3

Add some instruction for the user Add Event  Draw

Select the Font and alignment

Select the Colour

Add the Text and the position as you want

Similarly, add the second row of text.

SET the Object: car_down

Reset the variable “dead” to “false”

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

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

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

Preview

Start a block

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

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

When the car go outside the room

If the car y position of the car > room_height

Destroy the instance

Overlap

Check object Overlap

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

Complete the opening room End of Lesson 1

Lesson 2 Create the Room 1

Create the required “Object”

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

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

Set the Alarm0 as 300.

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

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

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

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

Then Set the step as below: car_down car_up Police car

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

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

Draw the petrol left box

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

Create car_racing

Set the variable “dead “ as “false”

Set the vertical speed as 0

What happen after “Crash” Racing car

Similarly for the car_up

Create the Room 1

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

Control the racing car to move Left

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

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

End of Lesson 2

When the racing car get the petrol

Create petrol

Set the speed of petrol as the background = 3

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

Go back to the setting of the racing_car.

Create the police car

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

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

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

y<0 || y > room_height+20

Completed!!

End of the Game

Additional tasks Add hearts to increase the lives Add coins to increase the score Add gun to shoot the other cars
