Game crashes from spawning enemies

[Brutile]

My game so far consists of enemies spawning at random locations on a terrain.

After testing half a dozen times, I've found that the game would consistently crash/stop responding after spawning exactly 130 enemies. I've also found that around the 80 mark, some enemies will be invincible. I've done all that I can to prevent memory leaks and after monitoring the memory usage, everything seems in order, but it still crashes after 130 enemies have spawned. Note that there are not 130 enemies alive at the same time, only 20 are allowed to be alive at once, and when they die, their entities and resources are released.

 

Is this likely a fault with my code or is there something in the engine that is causing this?

Without seeing code we can only guess. How do you spawn enemies?

[Brutile]

Spawning script:

In Start:

enemyModel = Model:Load("Models/Characters/Crawler/crawler.mdl")
enemyModel:Hide()

Spawn Code:

local enemy = Pivot:Create()
enemy:SetScript("Scripts/Objects/AI/Enemy.lua")
enemy.script.player = self.player
enemy:SetPosition(Vec3(math.random(-1000, 1000), 1000, math.random(-1000,1000)), true)

local pick = PickInfo()
local p = enemy:GetPosition()
--places enemy above the terrain
if self.world:Pick(p, Vec3(0, 0, 0), pick, 0.0, true) then
pick.position = pick.position + pick.normal
enemy:SetPosition(pick.position)
end

Enemy Script:

In Start:

--makes an instance of the enemy model in the spawning script
self.playerModel = enemyModel:Instance()
self.playerModel:SetParent(self.entity)
self.playerModel:SetPosition(Vec3(0))
self.playerModel:SetRotation(0, 180, 0)
self.playerModel:SetScale(1.5, 1.5, 1.5)
self.playerModel:Show()

self.entity:SetMass(10)
self.entity:SetPhysicsMode(Entity.CharacterPhysics)
self.entity:SetCollisionType(Collision.Character)
self.entity:SetPickMode(0)

 

Let me know if there is anything else you want to see.
