Buffer.write

Available since: Gideros 2025.1
Class: buffer_luau

Description

Writes data to the buffer by converting the number and writing a single byte or reinterpreting it as individual bytes.

buffer.writei8(b,offset,value)
buffer.writeu8(b,offset,value)
buffer.writei16(b,offset,value)
buffer.writeu16(b,offset,value)
buffer.writei32(b,offset,value)
buffer.writeu32(b,offset,value)
buffer.writef32(b,offset,value)
buffer.writef64(b,offset,value)

Parameters

b: (buffer) the buffer
offset: (number) offset from the beginning of the buffer memory, starting from 0
value : (number) one of the following:

• writei8: an integer number in range [-128, 127]
• writeu8: an integer number in range [0, 255]
• writei16: an integer number in range [-32,768, 32,767]
• writeu16: an integer number in range [0, 65,535]
• writei32: an integer number in range [-2,147,483,648, 2,147,483,647]
• writeu32: an integer number in range [0, 4,294,967,295]
• writef32: a single-precision floating-point number
• writef64: a double-precision floating-point number

Example

local str = "Hello Gideros!"
local b = buffer.fromstring(str)
local offset = 0
local value = 0
buffer.writei8(b, offset, value)
buffer.writeu8(b, offset, value)
buffer.writei16(b, offset, value)
buffer.writeu16(b, offset, value)
buffer.writei32(b, offset, value)
buffer.writeu32(b, offset, value)
buffer.writef32(b, offset, value)
buffer.writef64(b, offset, value)
