📝 Text – Your “Textual Communication”

What it is: Blocks that allow you to work with words, phrases, and letters within your program.

What it does: It allows you to work with words, phrases, and letters.

Example: Display the message “Hello World!” on an LCD screen, combine a number with a word (“Temperature: 25°C”), or send text via Bluetooth.

👉 It’s the robot’s written voice, the way it can express itself with words.

🧩 Fun Guide to Text Blocks (Clu-blocks Pro)

✍️ Important! Text blocks help your robot read, write, and play with words. You can join words, count letters, change characters, and even format messages. It’s like giving your robot a voice and a keyboard!

#	Block	What it does	Dropdown options	What the options mean
1	`"Hello Clu-Bots"`	A text string	—	You can type any message or word here
2	`Hello join Clu-Bots`	Combines two texts	—	Joins words together like LEGO blocks: “HelloClu-Bots”
3	`Ascii to Char 65`	Turns a number into a character	—	65 becomes “A” — great for secret codes or character tricks
4	`Char to Ascii A`	Turns a character into its number	—	“A” becomes 65 — the opposite of the block above
5	`toString x`	Converts something into text	—	Turns numbers, booleans, or other data into readable words
6	`get length Clu-Bots`	Counts how many characters are in the text	—	“Clu-Bots” has 8 characters (including the dash!)
7	`equals Clu-Bots Clu-Bots`	Compares two texts	`equals`, `startsWith`, `endsWith`	– `equals`: exact match – `startsWith`: begins with – `endsWith`: finishes with
8	`Clu-Bots get # 0 to 2`	Gets part of the text (substring)	—	Picks characters from position 0 to 2 — like slicing a word
9	`Clu-Bots get # 0 of Clu-Bots`	Gets one character at a position	—	Gets the first letter (position 0) — “C” from “Clu-Bots”
10	`Clu-Bots Random one character`	Picks a random character from the text	—	Great for games or surprises — like picking a random letter
11	`ASCII encode string Clu-Bots`	Turns text into encoded format	`encode`, `decode`	– `encode`: turns into ASCII – `decode`: turns back into readable text
12	`ASCII encode string Clu-Bots`	Choose encoding type	`ASCII`, `gb2312`, `gbk`, `utf-8`, `utf-16`, `utf-32`	Different ways to store text — `utf-8` is most common
13	`get Hello_Clu-Bots MidCharacter # 2`	Gets the middle character at position 2	—	Picks the third character (starts at 0) — great for puzzles
14	`Using string Clu-Bots to concatenate the sequence mylist into a string`	Joins a list of items into one string	—	Turns `[A, B, C]` into “ABC” using “Clu-Bots” as glue
15	`Hello_Clu-Bots Replace Clu with Clu-block`	Replaces part of the text	—	Changes “Clu” to “Clu-block” — becomes “Clu-block-Bots”
16	`Clu-Bots A B C Split`	Splits text into pieces	—	Breaks “Clu-Bots” into parts — great for analyzing words
17	`I love Clu-Bots Strim Both Space`	Removes spaces from text	`Both`, `Left`, `Right`	– `Both`: trims both ends – `Left`: trims start – `Right`: trims end
18	`format string Random No. % with: random int from 0 to 100`	Inserts a value into a sentence	—	Makes “Random No. is 57” — great for messages and scores
19	`Get string input(1+2*3) Execution result`	Runs a math expression inside a string	—	Calculates the result of the expression and returns it as text

🧠 Quick Tips for Students

Use join, replace, and format to build cool messages.
Use length, get, and split to explore and break apart words.
Use encode/decode for secret messages or advanced text tricks.
Use random and substring for games, puzzles, and creative effects.
