SDK 2.7.3, macOS 15.5.
This minimal lua example consistently crashes the simulator. I’m not sure what happens on device – I’m afraid to test that because it somehow leaves the simulator in a broken state where it hangs on subsequent launches, and I have to force quit and reopen it several times before it starts working again.
import "CoreLibs/graphics"
import "CoreLibs/sprites"
local gfx <const> = playdate.graphics
local testSprite = gfx.sprite.new()
testSprite:setSize(10, 10)
function testSprite:draw(x, y, width, height)
local testImg = gfx.image.new(10, 10, gfx.kColorWhite)
gfx.pushContext(testImg)
gfx.setColor(gfx.kColorBlack)
gfx.fillRect(0, 0, 10, 10)
gfx.popContext()
testImg:draw(0, 0)
end
testSprite:setStencilPattern(0.5) -- this in combo with the above draw method makes it crash
testSprite:add()
function playdate.update()
gfx.sprite.update()
end
I know the way this code creates a new image every frame is silly, it’s just a quick example that triggers the crash. In my actual project I have a sprite that creates new images on the fly in its draw method, but it caches them so it isn’t doing it every frame. This works fine unless I set a stencil on the sprite, at which point it crashes.
The crash still occurs if push/popContext are swapped for lock/unlockFocus.
