Hey everyone,
I’ve been working on implementing a movement system in my game, and I’m encountering some challenges. My goal is to replicate the movement of my custom character from the client side to the server side seamlessly, similar to how Roblox’s default character system operates.
However, despite trying various approaches, I’m facing issues with getting my “FlyingBrick” to work properly. Even when I give network ownership to the player, it causes the brick to become stuck to the ground, preventing it from flying as intended.
Here’s a glimpse of my current setup:
- Check out my Space Ship Test With Brick video for a visual demonstration
- Additionally, I’ve created a RemoteEvent to make a fake brick follow the player on the server side: ServerSideView video
The main issue I’m encountering is latency and imperfection in the server-side replication. Currently, I’m using tweens, but they introduce delays and inaccuracies, especially when the player moves at high speeds or changes direction suddenly.
Here’s the behavior I’m aiming for, demonstrated in the “Chasing Stars Online Demo” video: Chasing Stars Online Demo video
Any insights or suggestions on how to achieve smoother and more accurate movement replication would be greatly appreciated.
Thanks in advance!
Also here is the Code if anyone Instrested.
