Looks excellent? Have you tried a stress test to see how far it can go (i.e. multiple objects tracking a moving object).

Not yet max I tried is seven. will test later.

Pretty soon. It's on github so there's a clue...

Found a bug: http://dl.dropbox.com/u/39044660/path_bug.PNG

Thanks this is to do with the heuristic I think. Added a square root should make it better.

Here is a demonstration of the costing feature. The blue is lower than the dark green but they aren't blocked so the blip will move there. The blip will just try to avoid if possible very simple but great for AI. Combine this with rexrainbow's MoveTo behavior and it will be great!

Thanks. I was wondering where those bugs were. I just integrated a good open source astar script into a plugin. Few changes so far added cost weighting and an open source bit array script. works very well on iPhone 5. The plugin is called astar and the behavior is "pathfinder"

Very nice and thanks for mentioning that method and sharing the example! Sure seems like it'd help minimize code and optimize things.

Would be especially helpful in constructing a Terraria-like game methinks. :)

The full article mentions adding extra tiles Terraria style. Although the process is exponential so many many images to add! There will be faster ways of doing auto tiling. Currently my plugin only changes tiles that need changing rather than checking every tile which increases speed. This is just one optimization of probably many.

Thanks for the comment!

This is released.

Thank you,

Thanks rex! Your timeline method worked a treat. The plugin is a super fast path finding plugin that uses "pathfinder" behaviors. The original path finding algorithm is MIT License not my own code but the interesting part is someone added bit vectors and arrays to optimise it increasing speed *substantially*. Not sure who this person is though... Still MIT license so will upload eventually.

Using your first method would this allow dynamic access? As the data is changed in the plugin would it also update in the behavior? Sorry if this is a simple question! <img src="smileys/smiley5.gif" border="0" align="middle" />

I remembered you had some plugins that did this, thought I'd throw this out there before delving deeper.

Your plugins/behaviors are massively useful Rex! Thanks for your time and effort.

I noticed this post mentions access. I'll have a further look later.

Ashley or whoever

Is it possible to have a single plugin with some data/methods then have a separate behavior that can access this plugin data/methods?

If it is possible what would be the best/simplest way of access?

This would be very similar to the Solid behavior actually but I haven't had a good dig around that yet.

Thanks for your time,

Rez
