[H3LP] FindEntityInSphere

Hello. Can someone show me how to use FindEntityInSphere using sdktools?
I want to search for entities in sphere of 100.0 by looping.
On AMXX it can be done this way:

PHP Code:


		
			
while((iEnt = engfunc(EngFunc_FindEntityInSphere, iEnt, fOrigin, 100.0)) != 0)

Code:

"Games"

{

        "#default"

        {

                "Signatures"

                {

                        "FindEntityInSphere"  // "    magnitude: %f"

                        {

                                "library"       "server"

                                "windows"       "\x55\x8B\xEC\x83\xEC\x0C\x53\x56\x8B\xF1\x8B\x4D\x08\x57"

                                "linux" "@_ZN17CGlobalEntityList18FindEntityInSphereEP11CBaseEntityRK6Vectorf"

                        }

                }

        }

}

Thanks !

FindEntityByClassname + GetVectorDistance

Ye but that only finds by specific classname. And looping through entities is not a good practice anyways. For what I need now it could be enough, but I've other plugin where I wanna get all entities in given sphere.

Re: [H3LP] FindEntityInSphere

I'm sure FindEntityInSphere() do the same looping. Devs will correct me if I'm wrong.

Code:

        for( int i = 0; i < 4096; i++ )

        {

                if( IsValidEntity(i) && IsValidEdict(i) )

                {

                        GetEdictClassname(i, sTemp, sizeof(sTemp));

It looks that way.

Also why loop 4096 times you don't need to
you only can have 2048 entities +1 for world spawn.

Re: [H3LP] FindEntityInSphere

GetEntityCount is what I use for looping. I am unaware of any issues.

Worldspawn counts as one of the 2048 entities, specifically entity 0.

So for sphere it's a good idea to just start a loop from 1 to 2048 if I want to find all entities in a given distance, check if they are valid and get vector distance between player origin and entity origin? That's fine too, but using directly FindEntityInSphere from the server dll would be faster because it only makes 1 call, whereas using the mentioned method would make plenty of calls to the engine, each time it checks if the entity is valid and gets origin between the 2. Turns out that the signature is wrong, FF uses the 2006 sdk and I used IDA to search for that signature of bytes and it couldn't find any function. My plug-in also reported that the signature could not be found.

Yea dam thanks for pointing that out.

If your game is CSGO
you can use backup's extension

PHP Code:


		
			
 //Find entities within a radius. Pass 'null' to start an iteration, or reference to a previously found entity to continue a search

    //hscript FindInSphere(hscript, vector, float);

    public static native HScript FindInSphere(HScript a, float[] b, float c);

Re: [H3LP] FindEntityInSphere

If you end up looping, it's probably faster to use FindEntityByClassname with a classname of "*". (It supports wildcarding the end of the string). That will just loop over all entities in the global entity list, rather than checking every possibly index.
