Show(e) makes things appear
Hide(e) does the opposite.
Since you are going to use a trigger most likely you will need the entity ID, so, if your entity id is let's say 8 then rather than Hide(e) it would be Hide(8); anyway, it is not the best due it might change along with the game development; so, the best way is using the entity name.
Quote: "for k,v in pairs(g_Entity) do
if GetEntityName(k) == "Your entity name goes here" then
Hide(k) -- or Show(k) depending what you want to do
break
end
end"
Of course no the whole script, but can give you an idea.
