What classes as a big main game loop?

[andymc]

MY main game loop right now which runs for every frame of the game, is around 500 lines of code, there's plenty of loops in there to look through game objects too, but the game still runs very smooth without any hiccups, so I've not done any optimization yet. I expect the final game loop to be around 2000 lines of code, with a few more loops for additional game objects.

What's your main game loop size right now? And have you hit any performance problems yet? I'm using B4A with Libgdx and finding it blazing fast.

i think the code size is not the main factor. more important is how many loops you have inside your code and what size of lists (arrays) are those loops using.
if you will use big lists (like 2k items in it) you will start see performance problems.

Here's mine:
#Region Main Cycle
Sub MainCycle As Boolean
'DesignerMode
DesignerModeControl

'Prepare cache variables for function results
Dim inMap As Boolean

'Player - The following operations order must be kept:
'Control, Physics, Collisions, Update
inMap = isInMap(player.actor, True)
PlayerControl
PlayerWorldInteraction(inMap)
AnimationControlMainCharacter
ApplyPhysicsToTheMainCharacter(inMap)
PlayerCollisionDetector(inMap)
ContentUpdate(player.actor)

'Objects - The following operations order must be kept:
'Control, Physics, Collisions, Update
For Each obj As GameObject In ObjectList
For Each actor As Actor In obj.actor
If actor.active Then
inMap = isInMap(actor, True)
ObjectControl(obj, actor)
ApplyPhysicsToObject(obj, actor, inMap)
ObjectCollisionDetector(obj, actor, inMap)
ContentUpdate(actor)
End If
Next
Next

'Characters - The following operations order must be kept:
'Control, Physics, Collisions, Update
For Each character As GameCharacter In CharacterList
For Each actor As Actor In character.actor
If actor.active Then
inMap = isInMap(actor, True)
ApplyCharacterAI(actor)
AnimationControl(actor)
ApplyPhysicsToCharacter(character, actor, inMap)
CharacterCollisionDetector(character, actor, inMap)
ContentUpdate(actor)
End If
Next
Next

'Destructables
ApplyPhysicsToDestructables

'Camera
CameraUpdate(player.actor)

Return True
End Sub
#End Region
