Fungsi kode Motion yang ada di scratch

1. Code (move (10)steps) 

functions to give the sprite a step forward movement, for example: (move (5) steps) the number in the middle is 5 then the sprite will move 5 steps. we can change the number according to our wishes to make the sprite move several steps

2. Code  turn ↻ ( 15 ) degrees 

Function: Rotate the sprite to the right (clockwise)

The angle can be changed (e.g. 90°, 180°).

3. Code  turn ↺ (15) degrees

Function: Rotates the sprite to the left (counterclockwise).

Usually used to control the direction of movement.

4. Kode go to (random position)

Function: Moves the sprite directly to a random position.

No animation (moves straight away).

5. Kode go to x: ( ) y: ( )

Function: Moves the sprite to a specific coordinate.

Example: x = left/right  

              y = up/down

Useful for determining exact position. 

6. Kode glide ( ) secs to random position

Function: Moves to a random position with smooth animation (gliding).

Travel time can be set (e.g. 1 second, 2 seconds).

7. Kode glide ( ) secs to x: ( ) y: ( )

Function: Smooth movement to specific coordinates.

More realistic than “go to”.

8.Kode point in direction ( )

Function: Sets the sprite's facing direction.

Example direction: 90 → right

                         -90 → left

                            0 → top

                          180 → down

9.Kode point towards (mouse-pointer)

Function: Directs the sprite to a specific object.

Can be changed to: mouse-pointer

                             sprite lain

Often used for games (e.g. enemies following the player).

10.Kode change x by ( )

Function: Changes the horizontal position (X axis).

Positive values ​​→ to the right

Negative values ​​→ to the left 

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 

1. Kode set x to (-43)

Function: Sets the horizontal position (X axis) of the sprite to a certain value.

Example: x = 0 → center of screen

              negative x → to the left

              positive x → to the right

➡️ So the sprite immediately moves to position X = -43.

2. Code change by (10)

Function: Changes the vertical position (Y axis).

Positive value → up

Automatic moving object ball game

➡️ The sprite doesn't leave the screen, but bounces back.

5. Kode set rotation style (left-right)

Function: Sets how the sprite rotates.

Options:   all around → free spin     

              left-right → only facing left/right

              don't rotate → does not rotate

➡️ Suitable for characters to avoid being upside down.
