Spawning Hounds like a Varg

[FurryEskimo]

I've been poking around the varg (warg) code, and I know this determined how many hounds a varg summons but what actually spawns them?  I'm working to update the code I use now, which spawns a hound in a puff of smoke, but would like to figure out how hounds are spawned normally, slightly off screen.

local function NumHoundsToSpawn(inst)
    local numHounds = TUNING.WARG_BASE_HOUND_AMOUNT

    local pt = Vector3(inst.Transform:GetWorldPosition())
    local ents = TheSim:FindEntities(pt.x, pt.y, pt.z, TUNING.WARG_NEARBY_PLAYERS_DIST, TARGETS_MUST_TAGS, TARGETS_CANT_TAGS)
    for i,player in ipairs(ents) do
        local playerAge = player.components.age:GetAgeInDays()
        local addHounds = math.clamp(Lerp(1, 4, playerAge/100), 1, 4)
        numHounds = numHounds + addHounds
    end
    local numFollowers = inst.components.leader:CountFollowers()
    local num = math.min(numFollowers+numHounds/2, numHounds) -- only spawn half the hounds per howl
    num = (math.log(num)/0.4)+1 -- 0.4 is approx log(1.5)

    num = RoundToNearest(num, 1)

    return num - numFollowers
end

From varg stategraph, activated in varg brain

local function SpawnHound(inst)

    local hounded = TheWorld.components.hounded --> code/component where all the meat of it is
    if hounded ~= nil then --> if the code is present it does it thing

        local num = inst:NumHoundsToSpawn() --> code from varg caclulating the readonsable amont of hounds to spawn
        local pt = inst:GetPosition() --> saving location of the varg

        for i = 1, num do --> looping though each time a varg must be spawned in
            local hound = hounded:SummonSpawn(pt) --> spawining in the varg and saving it

            if hound ~= nil and hound.components.follower ~= nil then --> depending whenever you can make it a follower converting it over
                hound.components.follower:SetLeader(inst)
            end
        end
    end
end

From hounded code

local function SummonSpawn(pt)
    local spawn_pt = GetSpawnPoint(pt) --> checks location of possible spawn
    if spawn_pt ~= nil then --> if exists it does the code

        local spawn = SpawnPrefab( 
            (math.random() >= GetSpecialSpawnChance() and _spawndata.base_prefab) or --> if you're lucky you get epic hound
            ((TheWorld.state.iswinter or TheWorld.state.isspring) and _spawndata.winter_prefab) or -->depending on the season you can varied hounds for each season
            _spawndata.summer_prefab
        )

        if spawn ~= nil then --> if atleast one of the hounds were chosen it spawns in one
            spawn.Physics:Teleport(spawn_pt:Get()) --> spawns the hound at position given
            spawn:FacePoint(pt) --faces the target

            if spawn.components.spawnfader ~= nil then --> literalyly no idea
                spawn.components.spawnfader:FadeIn()
            end
            return spawn --> this is just so it works dw about it, remove it in your code 
        end
    end
end

From hounded code
I'm assuming this is what you want but if it works with normal hounds i'll leave the rest unless you made custom ones, just use this to get a location though unless spawnfader is the meat of it.

--math

local function GetSpawnPoint(pt)
	if TheWorld.has_ocean then
		local function OceanSpawnPoint(offset)
			local x = pt.x + offset.x
			local y = pt.y + offset.y
			local z = pt.z + offset.z
			return TheWorld.Map:IsAboveGroundAtPoint(x, y, z, true) and NoHoles(pt)
		end

		local offset = FindValidPositionByFan(math.random() * 2 * PI, SPAWN_DIST, 12, OceanSpawnPoint)
		if offset ~= nil then
			offset.x = offset.x + pt.x
			offset.z = offset.z + pt.z
			return offset
		end
	else
		if not TheWorld.Map:IsAboveGroundAtPoint(pt:Get()) then
			pt = FindNearbyLand(pt, 1) or pt
		end
		local offset = FindWalkableOffset(pt, math.random() * 2 * PI, SPAWN_DIST, 12, true, true, NoHoles)
		if offset ~= nil then
			offset.x = offset.x + pt.x
			offset.z = offset.z + pt.z
			return offset
		end
	end
end

@Thomas Die

Thanks a lot!  I hadn't noticed the 'hounded' code.

Sorry for the late reply, I've been pretty bus this weekend.
I'll give this code a try as soon as possible.

@Thomas Die
I think I got it!!

There were a few missing variables, and a whole function was missing, but I think I got it!

This isn't the whole thing, but it's what I used to replace the "hound.Transform:SetPosition(x, 0, z)  --Spawns the actual hound." part:

local function NoHoles(pt)  --Test code.
	return not TheWorld.Map:IsPointNearHole(pt)
end

local function GetSpawnPoint(pt)  --Test code.
	local SPAWN_DIST = 30  --hounded.lua::SPAWN_DIST
	if TheWorld.has_ocean then
		local function OceanSpawnPoint(offset)
			local x = pt.x + offset.x
			local y = pt.y + offset.y
			local z = pt.z + offset.z
			return TheWorld.Map:IsAboveGroundAtPoint(x, y, z, true) and NoHoles(pt)
		end

		local offset = FindValidPositionByFan(math.random() * 2 * PI, SPAWN_DIST, 12, OceanSpawnPoint)
		if offset ~= nil then
			offset.x = offset.x + pt.x
			offset.z = offset.z + pt.z
			return offset
		end
	else
		if not TheWorld.Map:IsAboveGroundAtPoint(pt:Get()) then
			pt = FindNearbyLand(pt, 1) or pt
		end
		local offset = FindWalkableOffset(pt, math.random() * 2 * PI, SPAWN_DIST, 12, true, true, NoHoles)
		if offset ~= nil then
			offset.x = offset.x + pt.x
			offset.z = offset.z + pt.z
			return offset
		end
	end
end

		local pt = Vector3(inst.Transform:GetWorldPosition())
		local spawn_pt = GetSpawnPoint(pt)  --Checks location of possible spawn.
		if hound ~= nil then  --The hound is ready for edits.
			hound.Physics:Teleport(spawn_pt:Get())  --Spawns the hound at position given.
			hound:FacePoint(pt)  --Faces the target.

			if hound.components.spawnfader ~= nil then  --Adds a fade effect when spawning.  --Note: Makes poof of smoke unneeded.
				hound.components.spawnfader:FadeIn()
			end
		end

I used to spawn the hounds at the player, with a big puff of smoke, but now they appear offscreen and run to the player! 

Also, the 'spawnfader' that you had no idea about, thank you for finding!  That's the hole reason I was using a puff of smoke in the first place!  See, when a Varg summons a hound, it just fades into existence.  I had no idea how, but this should help a ton!

Nice to hear, happy modding!
