Entity firing SWEP tutorials?

[cleversheep]

(Had a quick search, but couldn't find anything answering the question)

I'm currently attempting to make a SWEP that fires a custom entity in a straight line until it hits something, upon which I wish it to disappear and deal damage.

However, not only could I not find any advice on doing so, neither can I find anything on making entities in G-Mod in the first place.

Any help would be appreciated, etc.

For a rough outline of an entity, check this out:

I'll try to explain most of the stuff I use for you with the ents.
All entities contain the following functions:

The type of entity you want is called an anim, basically a prop that does something.

Most of the functions are self-explanatory, and the one I would use for this case is:

[B]You can use this to have set at a constant speed, or if you want to constantly increase speed.[/B]

For the part where it hits something, I use this one:
[URL]http://wiki.garrysmod.com/?title=ENT.PhysicsCollide[/URL]
It is called anytime something touches it.

Put together:

SWEP:
SWEP:PrimaryAttack()

local missile = ents.Create("sent_missile") // Sets up missile
missile:SetAngles( self.Owner:GetAimVector() ) //Sets your angles to where you are looking
missile:Spawn() //Spawns it

end

Your entity:
ENT:PhysicsUpdate( phys )

phys:SetVelocity( self.Entity:GetForward() * 3 )

end

ENT:PhysicsCollide( data, physobj )

local hitent = data.HitEntity // sets the entity it hit as hitent

if hitent:IsPlayer() then //Checks if it is a player

hitent:SetHealth( hitent:Health() - 5 ) //Subtract 5 health
self.Entity:Remove() //Remove itself

end
end
