What are good methods for hitbox detection?

[Wyzloc]

I want to be able to punch someone upside the head and send them flying with perfect aim. What other methods are there to detect hitboxes than raycasting (crazy math), and magnitude (bleh)?

You could try using Region3 detection

Region3 | Documentation - Roblox Creator Hub

If you want to do like 0 math then you can use the .Touched event but that’s not very reliable

Using Region3 is quite nice and accurate. I recommend using Egomoose’s module so you don’t have to do a ton of math.

Rotated Region 3 Module

Update: This module has served its purpose, but with the release of the new spatial query API this post is obsolete. It will be left untouched for learning purposes, but it’s strongly recommended to check out the built-in api solution instead. Recently I took another crack at an old module I wrote some time back. The goal of this module is to provide users with a way to create Rotatable Region 3’s which is useful for too many reasons to list. Even though this module (older versions) has been …

Mind giving a source for .Touched not being reliable?

Touching inconsistency

Main Problem I want to achieve creating parts that play music whenever you touch them. Currently it works, however there are some inconsistencies. The issues are: Sometimes, whenever leaving and entering the hitbox, the music will not play. Whenever jumping, it will call the TouchEnded event, which will stop the music I have been considering Region3's, however, you will need to detect them through while loops or RunService.Heartbeat. This will be performance heavy whenever having multiple …

There are plenty other cases of touched not working properly

[Wyzloc]

Yeah touched is super weird I tried using that to test hitbox and when standing still it’s some garbage.

Personally I like to use DistanceFromCharacter lol, just set the radius super low to detect a collision

Raycasting shouldn’t involve a lot of math, pretty sure Roblox handles all that for you. You just need to specify a starting position and a direction to cast a ray.
