Thanks RokuMarkn, that helps a lot! One last question(I hope), how do I check if a button on the remote is pressed? I've looked through the examples and documentation but I can't get anything to work.

See page 58 of the Brightscript 3.0 Reference. The roUniversalControlEvent object that you receive has a GetInt method that returns the id of the key pressed.

--Mark

I finally got it working, but how would I check if the button is still being held instead of just pressed?
This is what I have so far but it's not working:

while true
        x = x+xto
        y = y+yto
        scr.setalphaenable(true)
        BackGround(scr)      
        scr.drawobject(x, y, logo)
        scr.swapbuffers()                
        msg = wait(0, port)
if type(msg) = "roUniversalControlEvent" then
        if msg.getint()= 2
           yto = -5
        else if msg.getint()= 3
           yto = 5
       else	if msg.getint()= 4
           xto = -5
        else	if msg.getint()= 5
           xto = 5
        else if msg.getint()= 102
           yto = 0
       else if msg.getint()= 103
           yto = 0
        else	if msg.getint()= 104
           xto = 0
        else	if msg.getint()= 105
           xto = 0
       end if
end if
end while

Alright, I got that fixed, but now I figured out that the background is taking a ton of memory and causing the game to run super slow(from 59.9 fps to 8 ). Any suggestions?

When you press a button, you will get 2 events. First, you will get the press event (i.e. 2), then you release the button, you get the release event (i.e. 102). That allows a lot of flexibility. If you want to enforce only receiving "presses", then just set a release var when you get the press event, and clear it when you get the release event. (If you're not sure what I mean, I can give you a piece of code)

Also, I don't know if it makes a difference to roku, but I recommend making a small change to your code. Instead of using:

   if msg.getint() = 2 then
     ...
   else if msg.getint() = 3 then
    ...

Use this instead:

    key = msg.getint()
    if key = 2 then
        ....
    else if key = 3 then
        ...

Good question. I'm noticing that a bit on the HD version of my memory match game. I don't have the solution yet, but I am looking into speed improvements. I'll keep you posted with that I find.

Thanks YungBlood. The problem was msg = wait(0, port), I changed it to msg = port.getmessage() and it works fine.
EDIT:
I fixed the speed issue, the problem was bg = CreateObject("roBitmap", "pkg:/images/grass.png") was in the while loop. I moved it and now it's running at 60 fps.

Good to know you got it running better. I don't have the create object in my loop, but my code runs a bit slow in HD. Could simply be the number of objects I'm drawing...
