WEBVTT 00:00.000 --> 00:11.720 Welcome back, young coders! 00:11.720 --> 00:17.400 Today, we embark on an even more exciting journey in Scratch, exploring the realms of 00:17.400 --> 00:21.720 conditional statements, variables, and nested loops. 00:21.720 --> 00:27.120 These advanced tools will open up a world of possibilities, allowing you to create intricate 00:27.120 --> 00:29.520 and interactive projects. 00:29.520 --> 00:35.400 Let's dive into the deeper end of coding. 00:35.400 --> 00:40.160 Section 1 Introduction to Advanced Concepts in Scratch 00:40.160 --> 00:45.600 Imagine having the power to make your characters react to different situations or keep track 00:45.600 --> 00:47.560 of scores in a game. 00:47.560 --> 00:52.400 That's what we're about to explore. 00:52.400 --> 00:55.200 Conditional statements Conditional statements are like the 00:55.200 --> 00:57.360 decision-makers in your code. 00:57.360 --> 01:02.840 They can tell your sprite to laugh when clicked or change color when it touches something. 01:02.840 --> 01:06.080 Activity 1 Use Conditional statements 01:06.080 --> 01:13.120 Objective Learn to make your sprite react with if then and if then else blocks. 01:13.120 --> 01:18.120 Steps Choose a sprite, select a character that can show emotions. 01:18.120 --> 01:25.160 Introduce if then block, drag an if then block into your coding area, set up a condition 01:25.440 --> 01:29.040 Attach a when this sprite clicked event. 01:29.040 --> 01:35.480 Add an action, place a say ha ha ha, block inside if then. 01:35.480 --> 01:40.440 Test your code, click your sprite and watch it laugh when clicked. 01:40.440 --> 01:47.640 Explore if then else, replace if then with if then else for more complexity. 01:47.640 --> 01:51.880 Activity 2 Change the color of sprite objective. 01:51.880 --> 01:56.360 Set a project where your sprite changes color upon touching another. 01:56.360 --> 02:01.320 Steps Choose two sprites, let's use a cat and a dog. 02:01.320 --> 02:06.600 Add Conditional statement Use an if then block for the cat sprite. 02:06.600 --> 02:11.520 Set up touching condition, insert a touching dog block. 02:11.520 --> 02:17.920 Add color change action, place a change color effect block inside if then. 02:17.920 --> 02:23.680 Select the interaction, manually move the sprites to see the color change. 02:23.680 --> 02:27.480 Section 2 Understanding variables. 02:27.480 --> 02:31.920 Variables are like little storage boxes in your code holding important information like 02:31.920 --> 02:34.960 scores or counts. 02:34.960 --> 02:41.520 Activity 3 Variables Counting clicks Objective Learn to use variables 02:41.520 --> 02:44.440 by counting clicks on a sprite. 02:44.440 --> 02:49.800 Steps Select a sprite Choose a simple object like a ball, create 02:49.800 --> 02:57.720 a new variable, name it click count, initialize click count, set it to zero at the start. 02:57.720 --> 03:03.080 Increment on click Add change click count by one under a click event. 03:03.080 --> 03:07.920 Display click count, enable its visibility on stage. 03:07.920 --> 03:12.720 Select your click counter, watch the count increase with each click. 03:12.720 --> 03:19.840 Activity 4 Catch the falling star's game objective, create a game using a variable to keep score. 03:19.840 --> 03:25.480 Steps Set up your game Choose a night sky backdrop and a basket sprite. 03:25.480 --> 03:30.640 Initialize score, create and set the score variable to zero. 03:30.640 --> 03:33.880 Add a star sprite, make it fall from the top. 03:33.880 --> 03:40.440 Watch and score, increase score when the basket catches a star, play and refine, adjust 03:40.440 --> 03:44.360 the star's speed and baskets movement. 03:44.360 --> 03:49.560 Nested loops for complex actions Nested loops are like putting a smaller loop inside 03:49.560 --> 03:54.720 a bigger one, creating intricate patterns or repeated actions. 03:54.720 --> 04:01.920 Activity 5 Drawing a flower pattern objective Use nested loops to draw a complex pattern. 04:01.920 --> 04:07.840 Steps Choose a drawing sprite, a simple dot or object works great. 04:07.840 --> 04:15.280 Set up the pen, use pen down to start drawing, create the outer loop, use forever or repeat 04:15.280 --> 04:21.240 for the main pattern, add the inner loop, create a smaller segment of the pattern, design 04:21.240 --> 04:28.120 the pattern, use move and turn blocks for petal shapes, add variation, change the starting 04:28.120 --> 04:31.880 position for each repetition. 04:32.440 --> 04:36.960 Reflect and preview As we wrap up today's lesson, think 04:36.960 --> 04:43.240 about how conditional statements, variables and nested loops add depth to your scratch projects. 04:43.240 --> 04:49.720 They're not just tools, but gateways to endless creativity. 04:49.720 --> 04:53.960 Preview Next lesson Next time, we'll become coding detectives, 04:53.960 --> 04:56.080 solving puzzles and debugging codes. 04:56.080 --> 05:00.280 Get ready to enhance your problem solving skills and uncover the secrets of successful 05:00.280 --> 05:03.280 coding. 05:03.280 --> 05:08.160 Homework Create a new scratch project at home using loops creatively, 05:08.160 --> 05:11.960 whether it's animating a day in your life or a scene from a favorite story, let your 05:11.960 --> 05:16.160 imagination run wild.
