Should i spawn hitboxes locally or on the server?

[Omellete_777 (Hola123Hola456)]

im trying to make the best hitboxes i can, and i would like to know what are the best option when spawning the hitbox, on the server, or on the client and what are the benefits and the cons of using one over another?

Here’s a good comment (and thread) for this:

Hitbox in Client or Server

Client & Server hitboxes both have their drawbacks. Use client hitboxes if you want mediorce security (you can only do approximate checks on the server) & seamless gameplay smoothness. Use server hitboxes for high security, at the expense of accuracy. (laggier players will have a major disadvantage) For your question, I’d recommend going with client hitboxes, because: Attackers get a WYSIWYG (What You See Is What You Get) experience. Depending on your implementation, they can also be quite se…

I would personally use client hitboxes because it favors user experience (UX). Correct me if I’m wrong, but I’m pretty sure that the standard client-sided hitbox implementation is like:

@CLIENT-SIDED

swing sword → calculate hitbox on client → check what the player hit (on the client) → send that info to the server → server validates it → server does the magic (damage, cooldown, etc.)

The implementation above is usually used for raycasting, however, if you’re looking into something like query hitboxes (like the box hitboxes in Forsaken), you can do this instead:

@CLIENT-SIDED

swing sword → send hitbox position (on the client) to the server → check what the player hit (on the server) → server validates it → server does the magic (damage, cooldown, etc.)

Side note: if the player is lagging, the hitbox position may actually be waayy more off than the server-sided approach...? I'm not really too sure about this method -- you may be better off with the client-sided implementation above.

@SERVER-SIDED

swing sword → tell server you swinged sword → server calculates hitbox position → check what the player hit (on the server) → server validates it → server does the magic (damage, cooldown, etc.)

And if you’re looking into server-sided hitboxes, you can definitely look into velocity / ping prediction:

@SERVER-SIDED

swing sword → tell server you swinged sword → server calculates hitbox position + velocity / ping offset → check what the player hit (on the server) → server validates it → server does the magic (damage, cooldown, etc.)

Do your research on velocity / ping prediction though, it can get really messy and it might not even be recommendable tbh. It really is up to your discretion!
