From Customui Class

  Customui:setText(playerid, uiid, elementid, text)

--This function is executed when the player clicks on the block
local function clickblock(event)
 
    local playerid = event.eventobjid --Click on the player's mini number of the block
 
    local uiid = "6986982063319417057"--Interface ID
    local elementid ="6986982063319417057_1"--Text element id
    local text="Hello"-- The text content to be set
 
    --Set the display of the player's text ui element
    Customui:setText(playerid, uiid, elementid, text)
 
end
 
-- Register Event for Player.ClickBlock
ScriptSupportEvent:registerEvent([=[Player.ClickBlock]=], clickblock)

This Lua code creates an event handler that responds when a player clicks on a block in the game.

local function clickblock(event)

* Declares a function named clickblock that triggers on the event * The event parameter contains information about the interaction

local playerid=event.eventobjid

* Extracts the player's unique identifier from the event object * Identifies which player clicked the block

local uiid="6986982063319417057" // Interface ID
local elementid="6986982063319417057_1" // Text element ID 
local text="Hello" // Text content to display

* uiid: Unique identifier for the UI component * elementid: Specific text element within the UI * text: The message that will appear (“Hello”)

Customui:setText(playerid, uiid, elementid, text)

* Calls the game's CustomUI system to show text to the player * Parameters:

• playerid → Which player sees it
• uiid → Target UI component
• elementid → Specific element to modify
• text → Message content

ScriptSupportEvent:registerEvent([=[Player.ClickBlock]=], clickblock)

* Registers the clickblock function as a handler for Player.ClickBlock events * Syntax breakdown:

• [=[Player.ClickBlock]=] → The event type (block clicks)
• clickblock → Handler function name

This demonstrates:

• Event-driven programming (responding to player actions)
• Game engine API usage (CustomUI system)
• Basic Lua syntax (functions, variables)
• Game development concepts (player interaction, UI updates)

Result: When any player clicks a block, they see “Hello” in a UI element.

Example :

 -- Let's assume UIID and Element id is already defined 
 -- This Will set text with _Typewriter_ animation in 1 seconds (default playback once)
