Mobile interactive HUD. What's the way to do this?

[Ivan84]

I need to create this for a game:
an HUD made of an image with different squares inside it in the top of the screen, with the face of the teammates inside the different squares, their current health and some other information. I think i can do this (maybe), but i want also that during the game i can pick up an object from the floor and drag it inside one of this squares, and this should give the dragged object to the teammate inventory and show a texture under the square of the player who received the item.

It's difficult to explain, for instance think to the potions in Diablo II, when you drag a potion you can see a texture of it inside the HUD. I have one of this space under every square with the face of each teammates.

I don't need to know exactly how to do this (but if you want to tell me i would love you!) but to understand what to study to do it.
I read the mobile input system documents of UDN and the HUD techical guide, but i don't know if for this i must study Scaleform (is it possible to use this on IOS?) or if the normal Canvas can works.

You can use either Scaleform or Canvas for this. My recommendation is to use Scaleform.

Is it possible to use scaleform now with mobile? I read in many posts that it is not supported, but if you say that is possible probably it's the better way.

Latest versions of UDK support Scaleform.

Great, thank you. Another question if i can, is it heavier computationally than the canvas? My game is going to be a little too much heavy and on my ipad2 it isn't fluid now (but i have to optimize yet) so i'm trying to keep the complexity down.

Have to try it to find out.
