[SOLVED] Another health bar thread

gui health bar boxes 101


I'm not sure if it is what you have been looking for @krakov73 but explaining this solution looked like taking more time that actually sharing it done.

That looks lovely! I like the AI

Yeah this ai is little rough. I try to master use of boxes everywhere first
Glad it helped.

Hi,

 Impressive Andrew, very impressive. It clearly shows that you can do so much with playmaker!
I have added it to the wiki:

I think I will soon make a special page for such samples, cause more and more quality samples are shared.

I have however made a convenient custom action to do this billboard math in one go, which will be easier to replicate whenever:

Hi,

 Now the easiest way to go around this is the following:

I created an action to change the width and height of a gui texture:
http://hutonggames.com/playmakerforum/index.php?topic=2420.0

then I used the worldScreenToScreenPoint action:
https://hutonggames.fogbugz.com/default.asp?W571

that I set to "Normalize" which essentially is then becoming WorldScreenToViewPoint

then it's very easy to do a health bar following an object on screen.

I have attached a working example. Simply move the cube around using the editor, and edit the fsm "change gui texture size" value ( found in the inspector).

bye,

 Jean

Thanks Jean! Now I know how to do it with GUI at last
I wonder which method is better or faster.

[jeanfabre]

Hi,

 The fastest method will not be in terms of scripting but in terms of drawcall if you are on mobile, on desktop and web, I doubt you will every see a difference. That will be especially true if you start to have 20 30 healthbar or similar stuff on screen, then you WILL need to use systems like 2d toolkit or SM2 to combine all the 2d gui into one draw call.

 Actually that could be a good benchmark, taking Andrew system , using a lot more of playmaker, and custom actions.testing with a simply scene that keeps adding cubes with health bars and check perfs.

bye,

 Jean

I now have 3 examples that solve or effectively solve what I wanted to do, the support on here blows me away.

Thanks again all.
