Tips for PSP Dev

I posted this a while ago on a different forum. It might have more use here:
This is ment for PSP but it can also help to speed up normal flash apps also.

When I first had the idea to make a game for the PSP flash player, I loaded a game I already had. I was disappointed because of the extremely low frame rate. This can be easily changed. With the help of Genesis F5, I got my game from about 4FPS to about 20+frames. These tips will hopefully speed up your game.


Almost never set a variable to the same value continuously! Too much of this can slow the app down.

Another important thing is using an extremely small amount of enterFrame events. They are CPU killers. Once again, if you can, try to keep the script in the single root frame.

Another bad CPU killer is hitTests. Only detect hits if its needed, for example, if the player is walking right, only detect in that direction if the button is down.

Avoid redundant conditional checks. In one section, you added "&& cut == false" on each conditional, when they were all part of one global conditional. If they reference the same conditional, globalize it.

When you're doing a lot of if / then conditionals, always opt for a switch statement if you're checking for a value. Switch statements are faster and make the code more readable.

Another killer that I found rather annoying was the slow down produced from alpha blending and scaling. Try to use it only when absolutely necessary.

Good luck with the games!

Re: Tips for PSP Dev

I would like to see the game you made we could do with some more games on the site, and at the moment I have revision to do for some exams at the end of the month so have no time to make any more games.

There are some very good tips there most of which I use myself when I make a game and they definitely do work.

Re: Tips for PSP Dev

Hmm, my brain is being a bit slow today - if you're planning to use Smart FTP to upload stuff to the user ftp account, you can't, because it's not enabled any more. You can, however, still upload stuff - just go to http://www.pspflashgaming.com/user_uploads/ and if you're a registered user and logged in, you'll have your own filespace...

There's a post on the homepage about it here and a forum post here

Re: Tips for PSP Dev

yeah, it only allows .swf flash file uploads at the moment - i did this because i wanted to stop people uploading massive files and for security reasons.

Why do you want to upload music? Can't you just save it on your psp?

Re: Tips for PSP Dev

i honestly can't remember how i wrote the protection in... If it's the most basic of protection and it just looks for a .swf in the filename, then yeah (and it's not hugely secure). I think i might have done a slightly more secure version though which uses other methods to check the filetype...
