Profiling and Optimisation tools

[DRF.MGBV8]

Hi there

I am just finishing up my first app in solar 2d and Lua and I was wondering if anybody knows of any profiling or optimisation tools for LUA and Solar 2D ? I have had a quick look in the forum and cannot find much on it. I apologise in advance if this is a well known question I just can’t find much at the moment. Any advice greatly received Many Thanks David

Performance tip #193: Preload your fonts

So, I’m wrapping up a few sample projects that use my upcoming story/dialogue plugin and I decided to run some benchmarks. I know this is obvious to some, but I have been using Corona for almost five years and I never even considered how Corona loads fonts. So, this is for those two or three people wanting to optimise their games and who, like me, didn’t know about this yet. Simply put, creating a text display object for the first time takes a really long time. Let’s assume I have four custom f…

[Tips] Optimization 101

http://developer.anscamobile.com/content/performance-and-optimization Hey guys, just want to share some optimization techniques here with you. I will update this list when I can or add any techniques you guys may suggest. 1) Localization : Localizing Lua functions provides a decent > massive speed difference. How do you do this ? Like so : The slower way (Bad) local myRand = math.random(1, 10) The faster way (Good) local mRand = math.random local myRand = mRand(1, 10) Other example…

There used to be a tool called Corona Profiler, but it has been long abandoned. I don’t think that there are any that are specifically for Solar2D, but you could search for some generic Lua profilers (though your mileage will vary as they don’t account for a lot).

These days the most profiling that I do is using timers to measure differences in completion speeds of certain functions or measuring resource usage and resource usage changes when traversing scenes, but that’s just because most of my projects are rarely resource hogs, so I just want to find out if I have any leaks.
