What causes stuttering in my game with RigidBody2Ds?

jgrauman

Hi all,

I have a simple asteroids type game. I am using RigidBody2D's for ships, rockets, etc. They are working great. But when they move fairly quickly there is a pretty obvious 'stutter' (almost every second), and the graphics get 'choppy' whether they are ships, rockets, bullets, etc. The stutter is probably there even when objects are moving slow but isn't noticable in that case. In the monitor is says I am getting over 120 FPS and it never drops below that that I can see. I am running Godot_v3.1.1-stable_x11.64 under Linux. Any ideas of what to try or how to track down what is causing the stutters?

You should use:

func _physics_process(delta):

Rather than "_process()" for physics/movement related code.

Also make sure you are taking delta into account if you are hand-coding the velocity logic (or using "move_and_slide()" or "move_and_collide()", which already account for delta).

Thanks, that is a good suggestion, but I am already doing everything in _physics_process(delta). And I am only using apply_central_impulse() and apply_torque_impulse() for movement...
