Hi guys,

I found this piece of code for attaching a sprite to a player.

My question is, can i parent this to the actual weapon instead? And if so, how do i do this? (Note - the weapon will always be a knife).

Cheers

PHP Code:

stock AttachSprite(client, String:sprite[])
{
    if(!IsPlayerAlive(client)) return -1;
    decl String:iTarget[16];
    Format(iTarget, 16, "client%d", client);
    DispatchKeyValue(client, "targetname", iTarget);
    decl Float:Origin[3];
    GetClientEyePosition(client,Origin);
    Origin[2] += 25.0;
    new Ent = CreateEntityByName("env_sprite");
    if(!Ent) return -1;
    DispatchKeyValue(Ent, "model", sprite);
    DispatchKeyValue(Ent, "classname", "env_sprite");
    DispatchKeyValue(Ent, "spawnflags", "1");
    DispatchKeyValue(Ent, "scale", "0.1");
    DispatchKeyValue(Ent, "rendermode", "1");
    DispatchKeyValue(Ent, "rendercolor", "255 255 255");
    DispatchSpawn(Ent);
    TeleportEntity(Ent, Origin, NULL_VECTOR, NULL_VECTOR);
    SetVariantString(iTarget);
    AcceptEntityInput(Ent, "SetParent", Ent, Ent, 0);
    return Ent;
}

Get the edict* index of the weapon.

You'll also want to edit that stock and change references from clients to edicts, since well it should've been done that way from the get-go. Clients ARE edicts.

Thanks for that.

I've never really dealt with edicts, entities etc - so just trying to figure out my way through this.

After a bit of trial and error, and searching the API, I've tried this:

PHP Code:

new weaponent = Client_GetActiveWeapon(client);
    decl String:weaponedict[32];
    GetEdictClassname(weaponent,weaponedict, sizeof(weaponedict)); 


So, the total code i've used looks this, which compiles without errors / warnings.

PHP Code:

new weaponent = Client_GetActiveWeapon(client);
    decl String:weaponedict[32];
    GetEdictClassname(weaponent,weaponedict, sizeof(weaponedict));

    new Ent = CreateEntityByName("env_sprite");
    if(!Ent) return -1;
        
    DispatchKeyValue(Ent, "targetname", weaponedict);
    DispatchKeyValue(Ent, "model", sprite);
    DispatchKeyValue(Ent, "classname", "env_sprite");
    DispatchKeyValue(Ent, "spawnflags", "1");
    DispatchKeyValue(Ent, "scale", "0.1");
    DispatchKeyValue(Ent, "rendermode", "1");
    DispatchKeyValue(Ent, "rendercolor", "255 255 255");
    DispatchSpawn(Ent);
    SetVariantString(weaponedict);
    AcceptEntityInput(Ent, "SetParent", Ent, Ent, 0);
    return Ent; 


However nothing actually shows once this is called - so im assuming im doing something incorrectly?

Also, not quite sure what you mean by this sorry? How would i adapt to suit?

As you may know, Edicts are networked Entities. Essentially, there can be 4096(?) Entities, where there can be 2048 Edicts until the server crashes. So essentially server entities number 1 to MaxClients are reserved for players themselves. Entity index 0 is worldspawn, AKA the map for the most part. https://developer.valvesoftware.com/wiki/Entity_limit

This is why we loop from 1 to MaxClients when we want to scan for all active players like so:
This bit of information is also in the "Clients" include file, or located in the API.

MAXPLAYERS is not the same as MaxClients. MAXPLAYERS is a hardcoded value as an upper limit.  MaxClients changes based on the server. Both GetMaxClients() and MaxClients are only available once the map is loaded, and should not be used in OnPluginStart().                     
#define MAXPLAYERS        65   /**< Maximum number of players SourceMod supports */ 
#define MAX_NAME_LENGTH 32    /**< Maximum buffer required to store a client name */ 
public const MaxClients;    /**< Maximum number of players the server supports (dynamic) */

PHP Code:

for(new i = 1; i < MaxClients; i++)
{
     if(IsClientConnected(i) && IsClientInGame(i))
     {
          //Do stuff
     }
} 


You'll need to activate the entity. It's kinda weird, and using valve hammer while working with entities is the best way to go sometimes.

AcceptEntityInput(sprite, "ToggleSprite");
AcceptEntityInput(sprite, "ShowSprite");

To give you an example of how in SM you need to turn on the entities, here's a block from my plugin ShootFX, I've also commented some stuff to make it a little easier to understand

PHP Code:

public createFire(Float:Origin[3], ownerIndex)
{
    new fire = CreateEntityByName("env_fire");
    DispatchKeyValue(fire, "damagescale", "0.0");
    DispatchKeyValue(fire, "firesize", "64");
    DispatchKeyValue(fire, "firetype", "0");
    DispatchKeyValue(fire, "fireattack", "2");
    DispatchKeyValue(fire, "health", "15");
    DispatchKeyValue(fire, "ignitionpoint", "1");
    DispatchSpawn(fire);
    TeleportEntity(fire, end, NULL_VECTOR, NULL_VECTOR);
    AcceptEntityInput(fire, "Enable"); //Enable it since by default it's disabled
    AcceptEntityInput(fire, "StartFire"); //Turn that bitch on
    SetEntPropEnt(fire, Prop_Send, "m_hOwnerEntity", ownerIndex); //Certain games will make this the killer if it kills a player or entity
} 


Feel free to use that if you ever need it.

Thanks for that information, however unfortunately im still not sure how to attach the sprite to the weapon, instead of the client. (or an enity to a weapon, as i could use either a sprite or an entity).

The original code i posted definitely does work without having to turn on the sprite, or activate it - The SpawnFlags, "1" for env_sprite means start activated.

It's just the parenting that sprite to the client's weapon, instead of the client itself. Are you able to provide an example of how i can do that?

Thanks so much again

Well you'd need to get the entity index of the client's weapon, then hook OnWeaponSwitch.
There's a couple routes you could take with this:

• Mitchell's Weapon Attachment API
• GetPlayerWeaponSlot

Then once you have the weapon index, you just do the above except replacing client with the weaponindex.

Just a note on this, I never actually added an easy way to parent stuff to the weapon, just an easy way to get the weapon shoot position, however if you look at the code I parent an info_target to the weapon to get that position so you can easily rip that out and use it.
