Re: moving and scaling an image
Thanks to all the help with this. I ended up with a script that created sequential moves, with an image scale in between each. I am amazed at how smooth it is. This is the 'pull towards' script: on embiggen put item 2 of the loc of grc "near" into tend put item 2 of the loc of me into tbeginning repeat with j= tbeginning to tend step 100 get item 1 of the loc of me & "," & j move me to it in 2 ticks set the width of me to the width of me *1.05 set the height of me to the width of me *1.05 end repeat move me to item 1 of the loc of me & "," & tend end embiggen The move after the repeat loop corrects the location overshoot because of the change in graphic size. I had to chuckle, because this kludge actually looks like a nice little 'bounce' a la iOS. Ha!

Re: moving and scaling an image
Hi, if you want to move and scale at the same time, changing the rectangle property is your friend. You will want to do this in a send in time structure and calculate where the the corner points of your control need to be at the given time. You will want to lock screen before you set the rectangle and unlock it afterwards. For the iPad a frameRate of about 20 to 45 fps can be achieved, depending on how many objects you move and scale at the same time. It is advisable to not use the "best" resizequality option for the image. If you are choosing not to use images, there is room for a little more fps. No true 3d with this, as Ken already said. animationEngine handles this task quite effeciently I guess with the aeChangeRect command. You can even let your movement and scaling ease with it. :-) Cheers, Malte ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Honest injun! I don't want a 3d environment! I just want to give the most basic impression of pulling towards and pushing away of images. The maths isn't the problem, its the moving and scaling at the same time. I took a quick look at AnimationEngine, which clearly does lots of fantastic things I don't need. However, I would get it if it was the only way to solve this problem. I couldn't see any commands that obviously related to scaling on the move though - can anyone say definitively?

I've read interesting things about Franklin3d.com, but that doesn't seem to work on an iPad. If you don't care about true 3D, you might be able to get away with cheating with a 2D solution and a little extra effort to make things "appear" 3D, but not /really/ be 3D. You could calculate the math for this yourself, but there's always AnimationEngine for moving stuff around. -Ken ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
moving and scaling an image
Hello folks, I am trying to get an image to slide from the middle of the screen either to the top or the bottom. However, the screen has a perspective, as if you were looking down a bowling alley, with a vanishing point somewhere above the screen. To maintain the sense of depth, images 'pushed away' should shrink into the distance, and ones 'pulled' closer should embiggen. Any suggestions how this could best be achieved? The eventual destination of this may well be iPad, so any special considerations there would be welcome.
