[NS2 CreateEntity] How to spawn an entity in Client VM ?

Katzenfleisch

Hi,

I am working on mod and I wonder if there is a way to create entity on Client side only ? In my case I would like to spawn an alien entity which can only be seen and killed by one player (without any perturbation in the server side, for all the other player this one is just shooting at nothing).

I was looking in Utility.lua but CreateEntity is only Server. Any idea ?

Also, if it is possible to render an alien visible to a single marine in the team, this could do the job for what I need.

Thanks.

you have to create the entity on the server and check "function ViewModel:OnGetIsRelevant(player)" for an example. with that function you can limit relevancy to specific player(s) only. you also need to check out the physics group code, so other players wont be able to collide or shoot that entity.

After hours of tries and code source reading, I am sorry to ask again. (there are 2 maybe 3 files at least who use this function)

This is what I found on Weapons/ViewModel.lua
/**
* ViewModel is the class which handles rendering and animating the view model
* (i.e. weapon model) for a player. To use this class, create a 'view_model'
* entity and set its parent to the player that it will belong to. There should
* be one view model entity per player (the same view model entity is used for
* all of the weapons).
*/
==> CreateEntity(ViewModel.mapName):SetParent(??)

But i do not understand really how it should work. For me there are 3 elements
* The ViewModel class (created via CreateEntity)
* The "client only" element
* The player

Should I create a new class from ViewModel, and then call SetParent ? how do I join those 3 elements ?

Thanks

you create a new

class "YourClassName" (ScriptActor)

function YourClassName:OnGetIsRelevant(player)
return self.forPlayer == player
end

function YourClassName:SetTargetPlayer(forPlayer)
self.forPlayer = forPlayer
end


something like this! you dont need to use SetParent, this would attach the entity to the player, im sure you dont want that. also i dont really understand why you want to derive from view model, it has a very different purpose from what you want

In fact, I do no want to derive from view model, this was some test to try if it would work.
The major problem I have while overloading the OnGetIsRelevant() (like you suggest) is that it is never called.

I have tried the following
function CLASS:OnGetIsRelevant(player)
Print("Is called")
self.forPlayer = player
end

with CLASS equal to Player (or) Marine (or) Fade. (Marine -> Player -> ScriptActor)
I will try later to create a complete new class and see if it work.

Sewlek

you need to call
self:SetPropagate(Entity.Propagate_Callback)
in OnCreate

I will try today and tell you if its ok.
Thanks.

It work like a charm, thanks a lot.
