Using GFXP lib

Before you begin, import gfxp.lua from Source/lib folder into the source folder of your project.

import 'lib/gfxp'

It is enough to do this once, for example in main.lua

Use cases GFXP lib

The library includes 136 ready-made patterns (w/o inverted versions). To use any of them, all you need is to indicate its name. In any file with your code:

Option 1:

Declare a local variable

local gfxp <const> = GFXP

then specify the name of the pattern

gfxp.set('gray')

or

gfxp.set('dot-1')

or the inverted version (with transformation), just add an i at the end, for example:

gfxp.set('dot-1i')

or a custom pattern table

gfxp.set({0x55, 0xAA, 0x55, 0xAA, 0x55, 0xAA, 0x55, 0xAA})

or with mask

gfxp.set({0x55, 0xAA, 0x55, 0xAA, 0x55, 0xAA, 0x55, 0xAA, 170, 85, 170, 85, 170, 85, 170, 85})

Available transformation flags for named patterns:

i - Invert

r - Random

t - Transparency

Option 2: set only

Declare a local variable

local gfxp <const> = GFXP.set

then specify the name of the pattern

gfxp('dot-1')

or a custom pattern table

gfxp({0x7F, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF})

Option 3: lib only

Declare a local variable

local gfxpLib <const> = GFXP.lib

then specify the name of the pattern

playdate.graphics.setPattern(gfxpLib.gray)

or

playdate.graphics.setPattern(gfxpLib['dot-1'])
