Lua Programming Help Thread

ok i dont know if this is noob question or not, (probably is), ok so is there a way to to write so that whenever a the cursor goes on a certian picture it can trigger a command if the x button is pressed such as opening another image without writing something like this

if x0 < 80 then
if x0 > -10 then
if y0 < 242 then
if y0 > 215 then

EDIT, nvm allready figured out how to do it.

yeah, i know the feeling, because, actually, no one has answered my question, but its allright, i like helping people. I dont know what the problem it is. Very strange...

k i'm back finally my comp got all mean to me in a better way to put it so i did what he said and what do u mean missing an end well maybe explaining what im trying to do well help so here it is what i'm trying to do is make something where if you push left it will blit the a certain picture left and keep going but if i press right it will go back one picture and if i push left it will go forward a picture so thats wheat i'm trying to do i'll be glad to answer questions if it helps also it still just says running script anyway so you dont gatta go back a page or 2 to find my code i well post it here i havnt really made any changes to it because my dam comp's been screwey anywho here it is

Ok well doing vblankstart is what i did before I even posted and it didnt work but for some reason after like 5 hours of changing things around it finally works.

Yet I have 2 MORE noob questions:

1) if I use the vblankstart for the delay in the image blit when I hold down the button it will flash the picture then go back to waiting, then blit it again. Its in a non stop vblankstart then blit mode. All I want is just to wait then blit it. Yet using vblankstart doesnt seem to do that.

2)If I blit too many images at once in a somewhat small space they tend to not show up if i do it fast. Yet if I go really slow in pushing the buttons i can successfully get all of them to show, but the point of my game is to move fast to blit all the images when the buttons are pushed but they tend to show whenever they feel like it.

I hope I portrayed my problem well. If not im willing to answer questions because this is the only thing holding me back from completinga major part in my code.

Thanks in advance

Since we started a new page I think people might forget my problem so im posting it again. Not to be a jerk, just to bump the chacne of my question being answered.

Thanks again

Hi folks!
I'm writing an application in LUA with LUAEDIT and I'd like to test it on my PC before putting it in the PSP, but...
how can I simulate on my PC the commands for the PSP (cross, square, x and triangle or whatever) in order to see if everything is OK?
I don't like to move each time the .lua file because I don't want to change the paths of the images) :PC:

I did it, but I can't see any differences in this release...
so how can I play the buttons when I have my .lua program working in the DOS windows?
