Push Client HUD event

[gregdwilson]

In my mod Shadow Dragons I have an event where the player becomes tired after using an item through an even push. In single player this works fine but I cannot figure out a way to have the event pushed the client. I found out that you can't call inst.HUD since this is removed from the client on the server.

 

I also tried using a seperate mod that would run on the client and watch for the event but it still doesn't seem to work. Here is the code for the seperate mod I was trying to use. All implemented in modmain

 

local function StatusPostConstruct(self)
--Create the Tired status label

   self.tiredtext = self:AddChild(Text(GLOBAL.NUMBERFONT, 28))
    self.tiredtext:SetScale(1,.78,1)
    self.tiredtext:SetPosition(40,-55.5,0)
    self.tiredtext:SetString("Tired")

--Initialize the state.

    if self.owner:HasTag("tired") then
            self.tiredtext:Show()
        else
            self.tiredtext:Hide()
        end
 --Listen for triggertired even to update tired status      
    self.inst:ListenForEvent("triggertired", function(inst)
    if self.owner:HasTag("tired") then
            self.tiredtext:Show()
        else
            self.tiredtext:Hide()
        end
    end, self.owner)
    
end

AddClassPostConstruct("widgets/statusdisplays", StatusPostConstruct)

@gregdwilson, you have to use a net variable in order to send an event to the client. You can learn more about net variabled form this post: http://forums.kleientertainment.com/topic/48264-net-variable-types-and-sending-data-from-serverhost-to-clients/

So I tried net_variables but with no luck

 

Here is my function

 

local function fn()

       inst.AddComponent(
        inst.Tired = net_bool(inst.GUID, "triggertired", "triggertireddirty")  
        inst.Tired:set(true)
        inst:ListenForEvent("triggertireddirty", OnPlayerTiredDirty)
    end
end

 

which I call in common_postinit in my character lua

 

The listener function is then given by

 

local function OnPlayerTiredDirty(inst)
   if  inst.TiredStatus ~= nil then
        if inst.Tired:value() then
            inst.TiredStatus:Show()
        else
            inst.TiredStatus:Hide()
        end
    end
end

 

where TiredStatus is my HUD element set up in mod main by

 

function StatusPostConstruct(self)
    self.TiredStatus = self:AddChild(Text(GLOBAL.NUMBERFONT, 28), self.owner)
    self.TiredStatus:SetScale(1,.78,1)
    self.TiredStatus:SetPosition(40,-55.5,0)
    self.TiredStatus:SetString("Tired")
    if self.inst:HasTag("tired") then
            self.TiredStatus:Show()
        else
            self.TiredStatus:Hide()
    end
end
AddClassPostConstruct("widgets/statusdisplays", StatusPostConstruct)

 

I then use  "owner.Tired:set(true)" in the OnUnequip function in my custom item lua.

 

It is also changed in the onwake function of the sleepingbag component in modmain using

self.sleeper.Tired:set(false)

 

Again, this works fine in singleplayer using PushEvent and event listeners but I have been unable to get it to work with a client. Am I calling the statusdisplay wrong by using inst.TiredStatus:Show() in OnPlayerTiredDirty? I know that TireStatus initializes for the client becuase if I set it as visible when I declare it in modmain it shows up on the client. I just can't get it to switch with the net variable.

 

In the net_bool declaration

 

        inst.Tired = net_bool(inst.GUID, "triggertired", "triggertireddirty") 
 

what exactly do "triggertired" and "triggertireddirty" do. I thought they were like event markers which you can then listen to.

 

Any help would be appreciated

@gregdwilson, in the example you've given if you are using it exactly as shown, you have a coding syntax error. inst:AddComponent( is never adding an actual component. 

 

To Quote the relevant post:

 

 

In our latest hotfix, we've added a net_event wrapper.

net_event = Class(function(self, guid, event)self._bool = net_bool(guid, event, event)end)function net_event:push()self._bool:set_local(true)self._bool:set(true)end--Example:inst.screenshakeevent = net_event(inst.GUID, "screenshake")inst:ListenForEvent("screenshake", OnScreenShake)--Servers can push this and it will trigger on clientsinst.screenshakeevent:push()

Thanks @Kzisor, I figured it out. I put my solution in the thread you linked. Thanks for your help.
