[Beta] Realistic Bullet Holes

Sorry for being late, but I've faced a surprise which is just amazing!
The Bullet Holes I told you about, won't be just local, but synced on everybody's screen !!
What ?? Yes!  And all just by client-side. (no data is sent to server)
(onPlayerShoot is called for everybody, not just for the local player)

I've set a limit for bullet holes, as we don't want to use too many resources.
(even if I'm not sure how hard will this hit some low-end pc)
So, if you face lag when playing alongside other players, reply to this post with your pc details, and according to the replies I get, I will try to find a way around to fix it.


How does it work ?
Well, it creates a sprite on the hit position, in client side.
With help from habi, sprites are rotated to be facing the player in the moment of shooting, so they won't look like ugly dots around.
Every player has a limit of 10 bullet holes that can create, so once the limit is touched, the first one created will be removed, and so on.

Sprites won't be removed, because:

Suggestion : Donot let the holes fade away, it will bring more realism,  if anyone passes by he/she may see that someone here fought here before

But, as I said, if some players will start facing lag using this script, then I will rethink it and solve it out.
Meanwhile, big thanks goes to @habi for his math skills which I Iack alot !


That's all I guess, so I will just post the code which you need to use CLIENT-SIDE
Also, better save the "hole.png" and place it in server/store/sprites

newy = pos.Y + cos( angle ) * distance;
return Vector( newx, newy, pos.Z ); //assuming z more or less same.

Great Work man.

[habi]

it is a very cool feature.

You have to download the client side script, put it in your store folder and go ingame to see the beauty of it..

the beauty of the bullet holes..

[Sebastian]

it is very cool feature

Also customizable,  which makes it funny,  but you need to play with the script a bit.
You can get different holes' sprite for different types of weapons,  or personalized for different teams (red holes for the red team,  blue for the blue team,  etc)

Ery nice. Never thought this was ever possible in VCMP. (I didn't even think about implementing anything like that in VCMP).

[Shafin]

Wow nice

[ressam]

nice
