fill.y

Overview

This value is used to offset a repeating bitmap fill by a ratio of its height.

Instead of using a specific pixel value for this property, a value between -1 and 1 is required. This tells the GPU to offset the pattern by a full repetition in the vertical direction. So, using 0.5 will shift the pattern half of one repetition distance on the y axis.

An important distinction is that setting a positive value will shift the pattern in an upward direction, while a negative value will shift the object downward.

Example

-- Create a vector rectangle
local rect = display.newRect( 200, 200, 300, 300 )

-- Set the fill (paint) to use the bitmap image
local paint = {
    type = "image",
    filename = "texture1.png"
}

-- Fill the rectangle
rect.fill = paint

-- Offset the fill on the Y axis
rect.fill.y = 1
