Gmod Lua: Entity takes damage when owner collides with it

I have swep that throws the owner fly forward to a certain extent.

self.Owner:SetVelocity((self.Owner:GetUp() * 300) + (self.Owner:GetForward() * 1000));

I would like the owner to deal damage to anything he collides with.

Any help would be appreciated.

Just to check, if the player hits an object, does

GM:EntityTakeDamage get called? If so, you can modify the scale of the damage so it’s more noticable
