Re: Optimization help

Look into AdobeScout or hxScout to give you more details about what's taking so much time.

My most basic tip is to not create new enemies, instead using FlxGroup's pooling feature to recycle the enemies.

What I have on screen at once:

Player (SpriteGroup) and various bullets

flixel addons star filled background

some UI (eg hp bars, controls, buttons etc)

constantly spawning enemy sprites (FlxNestedSprite) that can shoot bullets etc too

explosions, particle effects (already cut down on these!)

Running the built-in debugger (on desktop) shows these stats:

update: 79 (2.7ms)

Draw: 46 (1.1ms)

DrawTiles: 46

QuadTrees: 61

Lists: 144

Any tips for optimizations? (i realize its difficult without the source code but still..) this is my first game.. really hyped to have it released in the next few days

Already have that, thanks!

You already have used Scout? What does the profile say is the problem?

[ThunderXBlitZ]

Its mostly draw related stuff... all taking 1ms

BitmapData.draw 
FlxTypedGroup.draw

FlxSprite.draw

copyPixels

camera.fillRect

and occasionally: (also 1ms)

emitter.recycle

player.flicker

flxpoint.set_x

Hmm, that's a contradiction to what Flixel is saying about draw/update, can you send the profile?

My first game is almost done, rly excited to release it this weekend. Only this lag issue is holding me back..

Btw, is FlxAtlas dev branch only? The tutorials i can find online are all in dev. No idea how to use the flxatlas in the stable version of flixel
