So I’m currently making an attack for a project right now, and I was planning to use raycasting, but after thinking, my attack has an area of attack, and raycasting may not be the best.
Example:
Should I use Region3 for this, or should I stick with raycasting?
Raycasting. Are you gonna create a region3 every time the player does an attack? Seems complicated
Edit: I suggest you cast multiple rays to cover up the area
You can’t just delete a reigion3?
Could you break the article down please, I’m kinda confused
Sorry about this, I’m still new to coding and professional articles still confuse me 
Yes, you can. Just seems complicated.
But wouldn’t making multiple rays also be complicated?
Hmm, I guess it would add more lines to your code. Well, you could do it with Region3. Best of luck!
Edit: Could you just send one raycast and make the attack vfx cover the entire area? And then you could check whether the VFX is touching a player?
OverlapParams is a new feature that allows integral raycasting, much like Region3, except it is far easier to work with and it was designed for better workflow. “OverlapParams” specifically, is a filter for possibly involved parts. Functions similarly to Raycasts, but with integrals.
Perhaps you should use OverlapParams for area damage as stated in the OP.
It really depends. There are a couple modules for raycast melee hotboxes but they are expensive to run.
If this is an area attack or a very large AOE attack you might want to use Region3 or if you want to have an accurate melee attack or projectile based use raycast.
As stated by other people, using Region3 is not recommended anymore, instead, the use of the new SpatialQuerry Api (OverlappParams) is. Functions such as worldroot:GetPartsBoundsInBox and worldroot:GetPartsBoundsInRadius replace the need for region3 in part detection.
