How do I start shattered pixel dungeon on "first thread" on MacBook m1 pro (Sonoma)?

[Prakash4844]

I have tried the following commands:

$ open -n ./Shattered\ Pixel\ Dungeon.app -args XstartOnFirstThread
$ open -n ./Shattered\ Pixel\ Dungeon.app -args -XstartOnFirstThread
$ ./Shattered\ Pixel\ Dungeon.app/Contents/MacOS/Shattered\ Pixel\ Dungeon -XstartOnFirstThread
$  open -n ./Shattered\ Pixel\ Dungeon.app &
$ ./Shattered\ Pixel\ Dungeon.app -XstartOnFirstThread

None of them worked. i always get the following output:

❯ java -jar is-seedfinder-2.4.1v1.jar -mode find -floors 4 -items in.txt -output out.txt
Error: ShatteredPD must start on the first thread in order to work on macOS.
  To avoid this error, run the game with the "-XstartOnFirstThread" argument
  Now attempting to relaunch the game on the first thread automatically:

sorry i have no idea as i have never owned a mac device. i'll keep the issue open and ask around to try and find a solution for the future if you have a discord i can send you an invite to a server where the seedfinder is hosted as a bot accessible through commands and hosted on my own PC

@Prakash4844 Add -XstartOnFirstThread before -jar

[ifritdiezel]

it appears that the automatic restart wipes all the arguments. i'm not sure how to fix this and don't have a mac device to test on. if someone creates a pull request to fix this i'll merge it

[Prakash4844]

Thanks! @TextualMold9830 @ifritdiezel

Add -XstartOnFirstThread before -jar

Solved the issue.

Now i am seeing

java -XstartOnFirstThread -jar is-seedfinder-2.4.1v1.jar -mode find -floors 4 -items in.txt -output out.txt
[Controllers] added manager for application, 1 managers active
[Controllers] removed manager for application, 0 managers active
Starting IS-Seedfinder, game version: 2.4.1

Not sure why it says game version as 2.4.1 when i have 2.4.2

Anyway, this can be closed.

@ifritdiezel is this not available for V2.4.2?

@ifritdiezel is this not available for V2.4.2?

dungeon generation is identical between minor versions so i didn't make a release for 2.4.2
