I noticed that in the late game, animations start to stutter because Find.TickManager.TicksGame and pawn.thingIDNumber become very large, causing the wiggle value to always be the same. This makes the animations look choppy.
To keep animations smooth in the late game, I used (Find.TickManager.TicksGame % 1000) and (targetPawn.thingIDNumber % 1000) to maintain variation. If you’re experiencing this issue, you can try this approach.
