How to draw a timer in scratch - How to draw a timer in scratch

Scratch is a graphical programming tool designed by MIT. By dragging and dropping building block code modules, users with no basic knowledge can easily create animations, games and interactive stories. It not only cultivates logical thinking and creativity in a fun way, but also relies on a global sharing community to promote learner communication and collaboration. It is a popular programming enlightenment platform around the world. Next, let the editor of Huajun explain to you how to draw a timer in scratch and how to draw a timer in scratch!

first step

Create a new character and use the Circle Tool to draw two concentric hollow circles, making sure that the center of the circle is aligned with the crosshair in the center of the canvas.

Step 2

Create a new pointer character and draw a thin line segment upward from the center

Key: Accurately align the bottom endpoint of the pointer with the center point of the canvas

Step 3

Create a new rectangular character as fill, align the bottom midpoint of the rectangle with the center of the canvas, and adjust the height so that it can completely cover the ring;

Step 4

Set pointer animation

Add a motion script for the pointer: when the green flag is clicked

Facing 90 degrees

Repeat 360 times:

Turn right 1 degree

Wait (total time/360) seconds

Step 5

Synchronized fill animation. Add a synchronization script for the fill bar: when the green flag is clicked

Move to the bottom

Repeat 360 times:

Increase the y coordinate by (fill height/360)

Wait (total time/360) seconds

Step 6

Add a ticking sound as the background sound, create a "total time" variable to control the timing duration, and adjust the fill height parameters to ensure a perfect match for the ring.

The above is how to draw a timer in scratch and the method of drawing a timer in scratch compiled by Huajun editor for you. I hope it can help you!
