Steps to reproduce:
1. Load this save:

timer_1000x_speed.zip: (394.91 KiB) Downloaded 114 times

2. Run this command:

/c game.take_screenshot{path=game.tick..".jpg"}

Expected result: The screenshot matches the file name.
Actual result: The screenshot is 129 ticks higher than the file name on my computer.

You can change game.speed to 1, to verify the timer really is in sync. It is a bug in the take_screenshot() function.

I was trying to automate screenshots of very short events far in the future, and this bug messes up my timing.

Hi, take_screenshot just queues screenshot request for rendering thread. If there are multiple updates in between rendering, screenshot is not from the same tick as take_screenshot was called.
You might call it a bug, but we won't "fix" it, I am sorry.

I found a workaround.

Code: Select all

/c game.take_screenshot{path=game.tick..".jpg"}
for i = 1, 1000000000 do end
