Vice City: Multiplayer

Okay So I had other methods of using spheres but I hate my methods. So I went into a big hunt in script releases in VCMP and LU, then I noticed Juppi's pay n spray release in LU "Awesome/amazing scriptwriter btw".

How in the heck did he determine what sphere is what, I am mind fu$#ed. I love it though,
So with that I want to take this as a learning opportunity.

The entire script is below \/.

Please I would really love to understand his method better as well in general, I would love the learning opportunity PLEASE :D

He saves the sphere ID in a variable inside the class.

So basically:

gSpheres <- array( 1, null );

gSpheres[0] = testSpheres();

class testSpheres
{
sphereId = 0;
function constructor()
{
local sphere = ::CreateSphere( pos, someradius, somecolor);
  if ( sphere )
  {
   sphereId = sphere.ID;
  }
}
}

Then you can do gSpheres[0].sphereId to get the ID.

Code is copy pasted, and probably doesn't work because how spheres are made, parameters all that shit. It should give you an idea though.

Thank you This did give me a better idea/comprehension.

The last idea I am trying to understand is to be capable of spiting things off,

Like a bomb shop,

Or even setting a camera matrix and putting that player in a virtual world similar to MTA for gta 3 for buying weapon options.

In that case would I have to use something like
[/list][code]function onPlayerEnterSphere(player, sphere) {
if (sphere.ID == 0 ) { etc etc

 or is there a more professional way to specify the spheres

I want to know how to implement Open/CloseGarage.

@Thijn I still do not know how to use correct methods of many spheres and specifying them to there correct ones. So instead with pay n sprays I removed spheres and now I am checking if that player is in the vicinity, if so process the garage. "Loop methods, ;D it's not laggy as your mind would imagine, It's actually pretty clean"

This is more professional in general as even Rockstar-North does not use spheres in the PNS :D.


I'm going to attempt to continue to not use spheres for garages etc. Instead use spheres for there correct usages, like virtual worlds.
