Identical method to Unity's FixedUpdate?

I am writing raycast based car chassis but it needs to run at fixed rate independently from the frame rate. If I use heartbeat it will be affected by frame rate and as of result the rate will fluctuate, which will cause the chassis to misbehave due to forces being applied inconsistently.

I need something like FixedUpdate which can be found in Unity’s game engine.

void FixedUpdate() {
  // ...
}

IIRC, isn’t Unity’s FixedUpdate fired for every physics frame? If so, you could try using RunService.Stepped.

#3

Roblox states in their engine documentation that the rate will vary depending on the performance of the machine, which is not what I am looking for.

#4

Unless you use the deltaTime of the heartbeat and times it to the cars momentum, I honestly don’t think there’s a roblox equivalent to Unity’s FixedUpdate… Hopefully I’m wrong, though.

#5

I found an old topic which found a solution to something similar to this a while ago, so I wrote a fixed update module.

Also to vouch for the module I’m using it in my game DashBlox for the physics overhaul/rewrite that I am currently working on, It’s also being used in my game RoStrike, and I will use it again when I attempt a 1-1 port of source engine movement to Roblox.
