I'm just trying to make polygons alongside a character like their hitbox but I don't know to make that a part of their Sprite so I'm doing it this way I tried first using a rect since I knew they were simpler But it doesn't seem to work Can you guys see any problems with my code

main.lua

import "ANIMATEDIMAGE"

import "LDtk"

import "CoreLibs/timer"

import "CoreLibs/object"

import "CoreLibs/sprites"

import "CoreLibs/graphics"

import "enity"

import "level/level”

local gfx = playdate.graphics

local anim = AnimatedImage

local timer = pd.timer

function playdate.update()

playdate.graphics.clear()

chunk1()

end

level.lua

import "CoreLibs/sprites"

import "CoreLibs/graphics"

pd = playdate

gfx = pd.graphics

pgp =pd.geometry.polygon

rect =pd.geometry.rect

arc =pd.geometry.arc

l = 0

r = 20

d = 400

a = 50

r1 = rect.new(l,r,d,a)

function chunk1()

gfx.drawRect(r1)

print(l , r)

if playdate.buttonIsPressed("a") then

    l = l + 100

    r = r + 100

end

end

It's because when you call rect.new it copies those values, so when you update the originals it doesn't update the copied version

Then is there any way to change the variables or such no way to change the position of a rect or Polygon Once it has already been placed

Not sure about polygon, but you can move a rect by simply setting the x or y property.

E.g. r.x = 10

You can move polygons like so:

local transform = pd.geometry.affineTransform.new()
transform:translate(x, y)
gfx.drawPolygon(transform:transformedPolygon(pgp))
