ok, i am trying to get the battery percentage into a variable, so i have this:
batlev = System.powerGetBatteryLif ePercent()
but when i try to run my program it says its not a proper command... anybody have a better way of getting the battery percentage (i just want a plain number in the variable)

**Jenay** · 09-28-2005, 03:12 PM

System.powerGetBatteryLif ePercent() is a number you need to convert it to a string to print it, something like

screen:print(425, 254, string.format("%d", battlvl), white)

okay, but i can't even get THAT far, it stops me right when it sees System.powerGetBatteryLif ePower() it says its a nil value... so maybe i am not using the right command or somthing, kuz lua just isn't wanting to execute that command... and yes i have the latest version of lua.

EDIT: here is the error i get:
error: index.lua:46: attempt to call field 'powerGetBatteryLifePerce nt' (a nil value)

**Jenay** · 09-28-2005, 03:25 PM

what's the error message exactly, and what's on the line number above it, it, and below it

**Koba** · 09-28-2005, 03:29 PM

read up ^ i gave the exact error, and here is whats above it:
-- battery power
and heres what is below it:
screen

rint(11, 2, string.format("%d", blvl), white)

Okay, I'm looking through all the luaplayer examples I know of to try to find how they implement it.

I'm not finding anything though

**Koba** · 09-28-2005, 04:50 PM

i wonder if lua has a official forum... i am sure someone there is a lua pro.

lol thats you??? ok well i fixed it, now when i try to go screen

rint(11, 2, string.format("%d", batlev), white) it says bad arguement 'format' (number expected, got nil)

**Jenay** · 09-28-2005, 05:49 PM

did you spell batlev the same each time?

**Koba** · 09-28-2005, 07:47 PM

heh, never mind, i fixed it, i just had to declare the variable as an integer before i told it what to contain, string.format so i'm ok now. i just need to know how to make a png keep its transparency, like, gradient transparencies, i dunno how to tell LUA to keep the transparency on a PNG image.
