How do I procedural animate ring/pie timer?

I'm not sure quite what else to call it. Attached capx is the first idea that came to mind, but it seems clunky, and I'm wondering if there is a better approach.

how about something like this...

spongehammer:

Thanks for the capx. Your approach looks great, but makes way too many objects for my game. I came up with another solution, which I'll post when I get it done, but mine is a trade off too: I need two 'force own texture' layers to accomplish the necessary masking. It's enough to make my iGPU hurt.

Once I post the capx, maybe someone else can figure out how to do it on one layer; masking makes my head hurt.

In the end, I think I'm going to go with a hybrid approach: spawning 4-8 segments and animating them the old fashioned way: multiple frames.

Here's the version using spongehammer sprite and Paster plugin.

Thanks for the post. I'll be on my desktop a little later, and I'll give it a spin. I'd forgot about the paster plugin!

Better late than never. Here is a procedural approach using 4 objects (two masks and two ring halves) that can display any kind of pie animation.

WARNING: this uses two 'force own texture' layers, so it's probably not a good approach for mobile.

OTHER WARNING: this is very much unfinished. The basic functionality works, but there are a lot of bells and whistles that don't work yet (I got a little overzealous ). If you have a lot of different pies that will be animating a lot of different ways, this might be useful. Otherwise, shinkan's approach should be alot more straightforward and funtional. Make of it what you will.
