These collision boxes are next to each other, not overlapping, however they are returned in as overlapping by sprite.allOverlappingCollisions.
Do you have code that demonstrates this? In the console in your screenshot it looks like the allOverlappingSprites array is empty, but maybe there is something I'm not seeing.
I created an example to reproduce what it looks like you're doing and it does not look like it's detecting any collisions.
If you run the following, it should output: #collisions: 0
import 'CoreLibs/sprites'
local gfx <const> = playdate.graphics
class('Box').extends(playdate.graphics.sprite)
function Box:draw(x, y, width, height)
local cx, cy, width, height = self:getCollideBounds()
gfx.setColor(playdate.graphics.kColorWhite)
gfx.fillRect(cx, cy, width, height)
gfx.setColor(playdate.graphics.kColorBlack)
gfx.drawRect(cx, cy, width, height)
end
local function addBox(x,y,w,h)
local block = Box()
block:setBounds(x, y, w, h)
block:setCollideRect(0,0,w,h)
block:addSprite()
end
addBox(0, 0, 32, 32)
addBox(32, 0, 32, 32)
addBox(0, 32, 32, 32)
addBox(32, 32, 32, 32)
addBox(64, 32, 32, 32)
addBox(0, 64, 32, 32)
addBox(64, 64, 32, 32)
local collisions = gfx.sprite.allOverlappingSprites()
print("#collisions: " .. #collisions)
function playdate.update()
gfx.sprite.update()
end

You're correct. It's 100% my not reading my own code. Sorry Dan, thanks helping though, I would probably have carried on not reading it properly if you hadn't replied.
Here's some code to prove it:
import "CoreLibs/object"
import "CoreLibs/graphics"
import "CoreLibs/sprites"
local pd <const> = playdate
local gfx <const> = pd.graphics
class ("Cell").extends(gfx.sprite)
function Cell:init(x, y)
self:moveTo(x, y)
self:add()
self:setCollideRect(0, 0, 32, 32)
end
Cell(32, 32)
Cell(64, 32)
Cell(32, 64)
local overlappingSprites <const> = gfx.sprite.allOverlappingSprites()
print("collisions: ", #overlappingSprites)
printTable(overlappingSprites)
function pd.update()
gfx.sprite.update()
end
Will generate this:
Will output this to the console:
collisions: 0
{
}
i.e. No collisions and an empty list of overlapping sprites.
