irregular vertical counter

[SolarB]

Hi,

My target platform is iOS.

I have a vertical counter with an irregular shape. I'm using the ASB to display it as it is the only way (that I can find) to do this.

However, I can only make it move downwards (example below). I want to move it upwards but stupid ASB only lets me align the image to top-left rather than bottom!!

bar.mfa

Very frustrated. If there are no workarounds I would request that ASB be able to align the image to whichever sides the user wants. This or be able to resize the dimensions of an active (to cut off bits of it) without stretching. Or an Interface Bar object port to iOS.


Also none of this works in HWA as the picture does not respond to dimension changes.

The workaround that I'm sure you don't want to hear, is to just make an active with a line of pixels removed from each frame until the object is totally erased... But that would be a massive amount of frames.

MMF really needs a way to select the draw area of an image... You could cut up sprite sheets or use the feature for doing exactly what you're trying to do. Basically a crop at runtime.

That, or masks.

There is a way using fastloops

Konidias - Yep, 200 frames eats up massive memory. Masks won't do it because the background needs to be transparent, I can do it with a shader but of course iOS...

Popcorn - Thanks, this is really good but probably won't work for a more complex image (the one provided was more of a placeholder) such as this:

bar.png

Black = transparent

SolarB - Haven't checked your mfa file, but you can probably do something like that using an Active Picture object and Offset in Y with Wrap turned off. Load your full bar image at the start of your frame, then Offset in Y by Max-Counter and reposition in Y by Counter-Max (I think!). You'll be limited to a horizontal top to your bar, but should be fine for transparent sections, you can even use alpha channel and save as a PNG to get a professional look.

Thanks Ayre, after a bit of a fiddle it works great! Tested on device too.
