HUD Custom Button

[gregdwilson]

I'm trying to make a button that when pressed allows me to run a function/push an event for my character.

 

I have created and placed the button and It is working up to the point where I can run functions that affect the character. Here is the code I have.

function DragonClawPostConstruct(self)	local offset = 0	local width = 1	local value = 75		self.DragonClaw = self:AddChild(ImageButton("images/hud/DragonClaw.xml", "DragonClaw.tex"), self.owner)	self.DragonClaw:SetScale(1,1,1)	self.DragonClaw:SetPosition(-296,190,0)	self.DragonClaw:Show()	self.DragonClaw:SetClickable(true)		width = value/100	offset = 29 - width * 29	self.DragonClaw.DragonClaw_cd = self.DragonClaw:AddChild(Image("images/hud/DragonClaw_cd.xml", "DragonClaw_cd.tex"), self.owner)	self.DragonClaw.DragonClaw_cd:SetScale(width,1,1)	self.DragonClaw.DragonClaw_cd:SetPosition(offset, 0, 0)	self.DragonClaw.DragonClaw_cd:Show()		function self.DragonClaw.DragonClaw_cd:SetValue(value) --out of 100		width = value/100		offset = 29 - width * 29		self:SetScale(width,1,1)		self:SetPosition(offset, 0, 0)	end		self.DragonClaw:SetOnClick(function()			self.DragonClaw.DragonClaw_cd:SetValue(math.random(100))			self.inst:PushEvent("DragonClawClick")		end)				end

and in my character config I added a listener under the master_postinit

inst:ListenForEvent("DragonClawClick", DragonClawClick)

and then a simple function

local function DragonClawClick(inst)    inst.components.talker:Say("You Clicked Me!")end

The "DragonClawClick" event doesn't get recognized by my character though. I can see the value change when I click it but not the message. I eventually want to make this server friendly but first I just want to figure out how to make it work. Any help would be appreciated.

It's not self.inst, it's self.owner, in the button.

In your character it is inst:ListenForEvent("DragonClawClick", DragonClawClick).

Thank you, that worked perfect.

[gregdwilson]

So I ran this in a server and the event would no longer push. If I put the code inside the SetOnClick function instead of pushing the event and changed inst to self.owner then it worked but only sporadically. Is there something special that I need to do for it to work with host/clients?

 

[DarkXero]

AddModRPCHandler(modname, "DCC", function(player)    player:PushEvent("DragonClawClick")end)self.DragonClaw:SetOnClick(function()    self.DragonClaw.DragonClaw_cd:SetValue(math.random(100))    SendModRPCToServer(MOD_RPC[modname]["DCC"])end)

Get those two in modmain.

self.DragonClaw inside the PostConstruct.

@DarkXero you are a genie. I got it working and the bugs worked out now I have a cosmetic thing I'm trying to fix. I make the character perform a custom action defined in modmain by

local DRAGONCLAW = AddAction("DRAGONCLAW", "Dragon Claw", function(act)    local target = act.target    local attacker = act.doer    local old_damage = attacker.components.combat.damagemultiplier    attacker.components.combat.damagemultiplier = old_damage*5    attacker.components.combat:DoAttack(target)    attacker.SoundEmitter:PlaySound("dontstarve/common/destroy_wood")    GLOBAL.SpawnPrefab("mining_fx").Transform:SetPosition(target:GetPosition():Get())    attacker:PushEvent("DragonClawCooldown")    attacker.components.combat.damagemultiplier = old_damage    return trueend)DRAGONCLAW.rmb = trueAddStategraphActionHandler("wilson", GLOBAL.ActionHandler(GLOBAL.ACTIONS.DRAGONCLAW,    function(inst, action)        inst.sg.mem.localchainattack = not action.forced or nil        if not inst.components.health:IsDead() and not inst.sg:HasStateTag("attack") then            return "attack"        end    end))

which works and causes the action to occur however when playing as the client the action happens but no animation occurs. How do I push the animation client side?

@gregdwilson, try making the client do ThePlayer:EnableMovementPrediction(false), or add the handler to the "wilson_client" stategraph.

 

You may want to switch the inst.components.health:IsDead() into inst.replica.health:IsDead(), since clients don't have all the components.

 

It's odd, you can be a client and get the yawn state, for example, despite it being invalid for clients, only valid in the normal stategraph. Not sure what is happening here.

@DarkXero, I duplicated the stategraph for wilson_client but switched to inst.replica.health and it worked like a charm. Thank you again.
