Lua Programming Help Thread

I set a sound file so that whenever I press X, it plays a sound (in this case, the mario boing). So when I run it and press X, the sound plays. The problem is that the sound is delayed. Any way I can speed it up or synch it so that it plays directly after (or when) I press the X button?

Thanks in advance.

Edit: Nevermind.. I got it. There really was no problem because when I ran it on the PSP, it worked like a charm. Damn windows Lua Player :P

OK here is my prob when i fire a bullet its not where the gun is its way off how can i do so that when i move my char the bullet place =
x and y = player x and y

Code:

play around with the 32 and the 16. I think thats the part that changes the bullets position.

i have a prob. i am making an animation of 10 images. when i run the script in luaplayer windows, it works fine. when i run it in psp luaplayer, it says that bg[x] could not be loaded.

x is always a number 1-10.

help.pls.

Mr.game i doesn't work So sad il have to find out.
