Need help with hit detection issues in Roblox games—hits don’t register properly

Hey everyone,
I’m having trouble with hit detection in Roblox—whether I use the official client or bootstraps like Bloxstrap, my hits often don’t register on other players or NPCs. I’ve tried fiddling with FastFlags and settings, but the problem persists even at low ping.

I suspect it’s related to how Roblox handles hit detection between client and server or how fast-moving hitboxes work. I’d appreciate any advice on:

• Better scripting methods for reliable hit detection (raycasting, shapecast, etc.)
• Known workarounds or existing hit detection modules/tools
• How to handle fast or growing hitboxes effectively
• Any similar experiences or fixes you can share

Thanks in advance!
