Can you make a (sprite) health bar for the NPC's?

Fits this thread more since it is about "npc".

that plugin will give you an general idea of how to do an health bar over the npc, thats why you were given the link, in that plugin ( from my guess after just seing the sprite used ) they most likely use a sprite that they put over the targets head, then set the frame of the sprite.

Have take a look on it already and it just confused me, so I found this on the last page -> http://forums.alliedmods.net/showpos...8&postcount=99
A bit less code which was a bit easier to understand, so I started to give it a try to make it over a NPC.
I am stuck at several lines, I don't know what to do about them and the events.
This is why I'm asking for a full code for the health bar.

[liinuus]

well, these plugins are just placing a sprite over the objects head, then they set the frames, frame 99 are for full hp, and frame 1 or 0 would be when theyre out of hp, then just use some math and calculate what frame it shud be, ofc this is just a quick explaination of how it works, you will need to check the code for the other settings you need to put on the bar, like the nodraw effects and such.

When the plugin starts, the entities for the health bars are created, on the addtofullpack, the origin of the bar is updated, and theyve hooke the "Health" event to change the size of the bar.

gj, will definitly use this tutorial if i will make an npc plugin

[Rirre]

Alright, this is what I've done.
model in create_npc() is replaced by EngFunc_SetModel when make_healthbar() is executed (which means the NPC is invisible in-game), I don't know how to fix this.
And at some lines I am unsure about.
Please, correct this script (also, remove the sprite/entity when it dies).

PHP Code:

#define NPC_CLASSNAME "npc"
