Where have you installed luaplayer ? You will probably need to give an explicit path to the luaplayer.exe. The why I tend to do things is install something along the following: 1) install luaplayer in c:\luaplayer 2) Make a new directory for the game/app i am working on like c:\luaplayer\test 3) So ...

First off check out http://www.luaplayer.org/ There you can download both windows and PSP versions of Lua Player. You can use any text editor to edit your code. You can test your programs on your PC using the windows version of LUAPlayer and then transfer the code to your PSP. The file extension for...

Wonderful. Thanks for the help (and the quick replies).

Hi Folks, I not sure if what I am trying to do is possible, hopefully someone will be able to shed some light. I want to pass a function name to a second function and get the second function to call the first one. eg: Main(SubMain,"blah") function Main(pName,pstuff&...

Yep, that's correct.

Check out these links, they are pretty usefully

It's pretty easy once you break down what you want to do: 1) See if you enemy is lined up with your character (check the X or Y setting were appropriate) 2) If he is lined up use a random number to decide whether or not to shoot (if math.random(1,3) = 1 then ......... end) As far as movement is conc...

You need the math.randomseed(os.time()) to ensure you random numbers really are random. If you don't seed the random number generator (or if you seed it with a known value) then the number sequences will be the same each time. By using os.time to seed it you use a different number each time the prog...

Thanks Drakonite,


Does the trick.

I am getting a 'strange' result using string.find to find a '.' (full stop) in a string. The function always returns 1 regardless of where the full stop is. The code below illustrates the issue. It prints two numbers the top one should be the position of the full stop within the string "abcdef....

Thanks guys,

Both your suggestions will enable me to acheive what I want.

_VERSION returns LUA 5.0.2 on both windows and PSP.

Another thought I had was maybe I could suppress the error message, is that possible ?

Hi Folks, I am coding using windows Lua Player. I want to display battery/memory information. The following works on my PSP but not on windows: screen:print (10,10,"battery: " .. System.powerGetBatteryLifePercent(),Color.new(255,255,255&#...

Thanks,

I think I've got it now.

Thanks for the replies, I am still cutting my first teeth with Lua and from reading some of the documentation it suggested that the waitVblankStart() should come before the flip (I see a lot of programs that use it this way). But from what you guys are saying it should always come after the flip, it...

Works the same with either screen.flip() or screen:flip()

Hi Folks, I have a question regarding how to use screen:flip() and screen.waitVblankStart(). From what I have read you should issue the screen.waitVblankStart() before you do a screen:flip() , to wait for the start of the vblank etc. So based on that the following should work: screen:print&a...
