I am not sure if this is the correct category but I could not think of where else to put this.
I went into a game that I have to test out some new features on when I noticed something strange:
There is a trail that I have that circles around a fixed point and changes in height. Previously, it would make one complete rotation before disappearing, but now it disappears only a quarter of the way through its revolution. I went into a game that I know did something similar with trails and found that they had the same issue. Did Roblox change the way that trail lifetime behaves?
It might be because it’s being drawn to a different song. The trails vertical movement also counts toward its length, so maybe a different song with higher peaks will use up that length a lot quicker.
Yes it is raining in this picture. The trails have shrunk sideways and longways and their shape has turned into a rectangle without me changing anything.
Oh wow, I noticed that too but I didn’t make the connection that it was based on FPS. I thought that maybe my raindrop animation code was being slowed down by low FPS but that wouldn’t make any sense since it’s not tied to FPS.
@UltChowsk this thread should be moved to #platform-feedback:engine-bugs
I have a suspicion that the unannounced trail behaviour change is because of a change in how trails are handled.
My trails look identical when I cap my FPS to 30 to as before the unannounced change around 2020-06-02T22:00:00Z.
So knowing that, I can only theorize that Trails were likely moved from being handled by LuaStep to RenderStepped, as LuaStep also works on 30 ticks.
Next to that, I also do not recall trail behaviour changing so drastically (or changing at all) when uncapping your FPS above 60.
