Trying to fade a graphic in on a roScreen.

trans=00
inc =5
while true
msg=wait(50, m.port)
trans=trans+inc
ba=createobject("roByteArray")
ba.push(255)
ba.push(255)
ba.push(255)
ba.push(int(trans))
hexcolor="&h" + ba.tohexstring()
? hexcolor
screen.drawobject(   410,  240,  saverbitmap, hexcolor)  'LOGO
screen.swapbuffers()
End while	

the byte array is incrementing properly
&hFFFFFF0D
&hFFFFFF12
&hFFFFFF17
&hFFFFFF1C
&hFFFFFF21
etc.

I am getting a type mismatch on the hexcolor variable above on the screen.drawobject line.

hexcolor &h8010 bsc:roString (2.1 was String), refcnt=1

I suspect it is some sort of issue between strings and integers but don't know how to deal with this with a hex value.
if i paste in a value from what the bytearray is outputting it shows the graphic fine.
would appreciate any help thanks.

That's a bit more complicated than it needs to be. You can do something like this instead of creating the bytearray:

hexcolor = &hFFFFFF00 + trans

Thanks Mark, that is indeed a lot simpler, and it works!
