Update : I tried removing everything, even the player, and there is still a lag ! It seems like half the problem comes from the looping background, it’s as if on some irregular number of seconds, there is a jerky movement as if the background pauses and generates again.
Hello everybody,
I’ve been scratching my head over this problem of general jitteriness/latency all over my minimal project (2d, mobile). At first – as seen in the first video – there is just a player with camera moving to simulate a sort of runner game, there is some jitteriness there but it’s still minimal, the moment other game objects are introduced – cats, as seen in the second video – the game become more jittery, both the game objects and the background.
When i try to add interpolate to game objects, it just makes the player jump become inconsistent without solving or improving the latency/jitteriness. So i suspect it may have something to do with the way framerates are processed, in another phone there is less lag – but still more than enough to ruin the game -
I know the problem is complicated for a beginner, having to do with Unity Game Engine/Frame Rates and i don’t expect some magical 1 paragraph solution, but i’ve been searching the whole of the internet just looking for a hint, an idea of where/what i have to look for and i still can’t find any. So i’m asking for the community generosity in directing me towards any hint/direction/rough draft of where to go.
Those videos are from a test on mobile. (In the first 5/6 seconds there is a jitteriness from the recording app, don’t mind that)
Video 1 :
Video 2 (with GameObjects) :
Video 3 (with a static GameObject, to see if the problem comes from the animator/animation) :
Code and more elements/pictures :
Player GameObject Code :

What i’m trying to do with the Player Code as it may seem – and it is – convoluted. Player moves once (or twice if double tap under a certain time constraint) top or bottom. With a constraint on top and a constraint on bottom.
