hook.Add seemingly does nothing when inside SWEP:SecondaryAttack/PrimaryAttack

[MrPlaidSquirrel]

function SWEP:SecondaryAttack()
hook.Add( "HUDPaint", "HUDPaint_DrawABox", function()
surface.SetDrawColor( 0, 0, 0, 128 )
surface.DrawRect( 0, 0, 128, 128 )
end )
end
why am i so bad at this shit

[c👌de_g🎷]

SecondaryAttack will only run on the client in single-player, and even then it's not always guaranteed. You should network to the client.

[MrPlaidSquirrel]

I understood none of that

[c👌de_g🎷]

HUDPaint is a clientside hook. SecondaryAttack is only guarenteed to be called serverside. Network to the client from SecondaryAttack to add the hook.

[MrPlaidSquirrel]

I'm really just messing around in singleplayer right now, but what makes the Clienside version of SecondaryAttack bad?

[c👌de_g🎷]

It's never called on the client in single-player, and only for prediction reasons in multi-player - in other words, it doesn't have to be called.

[MrPlaidSquirrel]

By the way you're wording this it sounds like SecondaryAttack shouldn't be used

[c👌de_g🎷]

There's nothing wrong with SecondaryAttack, but if you want to do something on the client from it, you should network.

[MrPlaidSquirrel]

Please bear with me here.
So SecondaryAttack wont run on a clientside lua script?

[c👌de_g🎷]

SecondaryAttack will always run serverside. It will run clientside in multi-player only (it will NEVER run clientside in single-player), but it should only be used for prediction matters (which is linked above). If you want to do something like add a clientside hook from SecondaryAttack, network to the client from the server.

[MrPlaidSquirrel]

Still confused to why it would run Clientside in multiplayer if it's for handling things like firing bullets

[c👌de_g🎷]

The prediction page explains that - the client will also "fire the bullet" to make it appear instantly and smoothly, regardless of server ping. It's not needed in single-player since the client has server information instantly.

[MrPlaidSquirrel]

Oh I know about that, I'm just saying wouldn't the fire bullet command also have to run on the server so it could relay damage to other clients?

[TFA]

yes, it runs on both. on server, it fires the bullet and networks it to everyone except who shot it ( except in SP ). Client is only visible on the shooting client.
