im tryin to make the white box that appears around my sprite transparent

+ Code Snippet

rem load images
load image "c:\users\jon\pictures\sprites\spriteup.jpg",1
load image "c:\users\jon\pictures\sprites\spriteright.jpg",2
load image "c:\users\jon\pictures\sprites\spritedown.jpg",3
load image "c:\users\jon\pictures\sprites\spriteleft.jpg",4

rem state what image first comes out

c = 2
x=1
y=1
sync rate 256
do
cls
ink color,0
rem keys = what image is show ex: leftarrow is char facing left

if upkey() then c = 1 
if rightkey() then c = 2
if downkey() then c = 3
if leftkey() then c = 4

rem character movement

repeat if rightkey()=1 then x = x+1
sprite 1,x,y,c
until rightkey()=0  

repeat if leftkey()=1 then x = x-1
sprite 1,x,y,c
until leftkey()=0

repeat if upkey()=1 then y=y-1
sprite 1,x,y,c
until upkey()=0 

repeat if downkey()=1 then y=y+1
sprite 1,x,y,c
until downkey()=0

You can use SET IMAGE COLORKEY to set the color that will be transparent. But because your using .jpgs it'll be hard because .jpgs don't keep solid colors. It'll probably only make a little bit of the images transparent and you'll still see some off-white on the sprites. It's best to use .png for all images so they stay exactly the way their drawn (no color changes) and .pngs allow you to use transparencies (like a window that you can see through).

Edit: Wow that's a huge SYNC RATE you've got there.

Most people use 60 or totally off like I do (at zero... but when you do that you need TIMER() based movement).

Edit again: I just looked at the bottom of your code. You don't have to use REPEAT/UNTIL because just having an IF/THEN to check for the arrow keys will look just the same without the REPEAT/UNTIL for each key. You can also have more than one command within an IF/THEN check if you drop the THEN and use ENDIF to close the IF/THEN conditional check (so there's no need to have two checks for arrow keys). And you only need one SPRITE command to show where the player is outside of any IF/THEN check.

If you haven't checked them out yet take a look at TDKs tutorials to learn the basics:
