I wonder if someone might throw up a little code that will show a plain cube rotating in front of a background image?

I am new to DBPro and have been playing around. I wanted to do what I described above, so I took my best guess at it and it's almost there, but when the object is rotating it wipes out a section of the background with gray.

Here's what the code looks like now:


The commented out bits just texture the cube and make it appear to fly away into the screen. I turned them off while trying to figure it out, but those parts work fine. I just can't see what I'm doing wrong...

Thanks!

1. Place the following at the top of your code: SYNC ON : SYNC RATE 0

2. Place a SYNC command at the bottom of your loop.

3. If you can see the backdrop (anywhere where you can't see anything else) change SET BACKDROP OFF to SET BACKDROP ON.

That should smarten up your code.

No dice Jane

That gives me the exact same behavior. I'll attach a snapshot showing what I mean.

If I turn the backdrop on, my background image is replaced by a blue screen with the cube spinning, so that doesn't help either.

Thanks for helping out!

I'd make it a sprite also. I think they may be faster and you can also do more with them if needed. So add this:

then in your loop:
paste sprite 1, 0, 0

OK, changing it to Load Image and then putting Paste Image in the loop doesn't work. Basically, it draws the background, draws the cube, then pastes the background over the cube, hiding it from view. Even if I throw a Show Object in the loop after the Paste Image, I still can't see the cube.

Off to try the sprite method...

Thanks!

Sprite method doesn't work either. I never see the cube at all that way.

Any other ideas are more than welcome...

Ahhh, Draw To Back was the ticket! Thanks WindowsKiller!

For those following the discussion, here's the final code that works as I had wanted it to:
