I am trying to learn Lua, but in the tutorials on the garrysmod wiki do not explain what hooks are.

Can someone explain what hooks are, and/or add a tutorial there explaining them?
Hooks "hook" into certain functions..
Here's an example, dono if it will make sense.
[b]Function[/b] - This is a normal function, no hooks.
[lua]
function GM:PlayerSpawn(p)
Msg("hi!\n")
end
-- When you spawn you will see the message - hi! - in your console.
[/lua]
[b]Hook[/b]
[lua]
function MySpawnFunction(p)
Msg("How are you?")
end
hook.Add("PlayerSpawn", "HookName", MySpawnFunction)
-- I just "hooked" into the PlayerSpawn function, no when you spawn
-- you will see.
-- hi!
-- How are you?
[/lua]
Hope that makes sense.
Basically this hook system lets you set up a function to be run when a certain event happens, like a player dying, an entity taking damage, a prop being spawned etc. So if you wanted to ban a model you'd add a prop spawn hook that checks the model and blocks the prop from being spawned if it's a banned model.
If this clarifies: a hook is a function that is called when the function you have hooked into is called.
Which is exactly why I wonder why most aimbots actually use hooks. Mine doesn't :wink:
