[Inhib]

I'm writing a plugin, and I need to be able to track the projectiles fired by a specific player, and I currently have no idea how to do this. By track, I mean to identify so I can remove it or other stuff. One of the problems with other methods is that there might be multiple of a particular type of projectile. So if possible, I would like to find the 'newest' projectile fired by a certain player.

Would appreciate any help

PHP Code:

#define rocket_name "tf_projectile_rocket"
new players_rocket[MAXPLAYERS+1]; //this only tracks the latest rocket fired by each client

public OnEntityCreated (entity, const String:classname[]) {
    if(StrEqual(classname, rocket_name)) //search for rocket projectile model
    {
        new entity_owner;
        entity_owner= GetEntPropEnt(entity, Prop_Data, "m_hOwnerEntity"); // retrieves the client who owns the entity
        players_rocket[entity_owner] = entity;
        
        SDKHook(entity, SDKHook_Touch, On_Projectile_Touch); //this means the rocket has exploded. set players_rocket[entity_owner] = 0 here
    }
}

what would the classname be for a demoman pipe, or say a sandvich? is there any index for all these?

[turtsmcgurts]

You should be able to use GetEdictClassName.

Add that into OnEntityCreated and have it print the classname out, then fire the pipe.

What datatype does
"entity_owner= GetEntPropEnt(entity, Prop_Data, "m_hOwnerEntity");"
return?
I'm guessing it's an integer, for the clients entity id, but when I print it to the server, it returns -1, this causes all following operations to break.

Here's the portion of it in my code:
new playerpipe[MAXPLAYERS+1]
public OnEntityCreated (entity, const String:classname[])
{
if(StrEqual(classname, "tf_projectile_pipe"))
{
PrintToServer("Found Pipe");
new String:pipeowner;
new String:pipeownerstring[10];
new Float:pipevelocity[3];
pipeowner= GetEntPropEnt(entity, Prop_Data, "m_hOwnerEntity");
//Format(pipeownerstring, sizeof(pipeownerstring), "%d", pipeowner);
//PrintToServer(pipeownerstring);
if(pipeowner==-1)
{
PrintToServer("-1");
}
playerpipe[pipeowner] = entity;
GetEntPropVector(playerpipe[pipeowner], Prop_Data, "m_vecVelocity", pipevelocity);
TeleportEntity(pipeowner, NULL_VECTOR, NULL_VECTOR, pipevelocity);
RemoveEdict(entity);

//SDKHook(entity, SDKHook_Touch, On_Projectile_Touch); this means the rocket has exploded. set players_rocket[entity_owner] = 0 here
}
return Plugin_Continue
} <------Line 105

sourcemod compiler returns "/groups/sourcemod/upload_tmp/textBAkXp5.sp(105) : warning 213: tag mismatch" and I have no idea why.

I imagine that tf_projectile_pipe doesn't use "m_hOwnerEntity".

Using the sm_dump_datamaps command and searching for "tf_projectile_pipe", I found this.

Try replacing "m_hOwnerEntity" with "m_hThrower".

[Inhib]

the reason the output was -1 is because at (OnEntityCreated), the owner has not been assigned, avoided this by using SDKHook to hook that projectile and assign the owner when (SDKHook_Spawn).

So yes, it does use m_hOwnerEntity.

BTW whats that link abt? It looks really interesting, might be useful for future reference.

[turtsmcgurts]

It shows the different properties for the entity. It's useful for a lot of different situations.

PHP Code:

SpawnRocket()
{
    rocket_entity = CreateEntityByName(rocket_entity_name); //creates a new "tf_projectile_rocket" entity 
    
    TeleportEntity(rocket_entity, origin, angles, velocity); //sets the position, angle and velocity of the rocket so it flies to where you want.
    
    SetEntPropEnt(rocket_entity, Prop_Send, "m_hOwnerEntity", client); //sets the owner of the rocket
    SetEntData(rocket_entity, FindSendPropInfo(rocket_class_name, "m_iTeamNum"), team, true); //sets the team value of the rocket
    SetEntDataFloat(rocket_entity, FindSendPropInfo(rocket_class_name, "m_iDeflected") + 4, 100.0, true); //not sure why, but this is required in order for it to do damage.
    SetEntData(rocket_entity, FindSendPropInfo(rocket_class_name, "m_bCritical"), 1, 1, true); //set it to be critical
    
    DispatchSpawn(rocket_entity); //spawns the rocket
}

Ammo(client, amount)
{
    new weapon = GetEntPropEnt(id, Prop_Send, "m_hActiveWeapon"); //this allow us to read or manipulate properties of the clients active weapon
    if(IsValidEntity(weapon))
    {
        new ammo_in_clip = GetEntProp(weapon, Prop_Send, "m_iClip1"); // this would retrieve how much ammo is in the persons clip.
        
        SetEntProp(weapon, Prop_Data, "m_iClip1", amount); //this would set the amount of ammo in the persons clip to 'amount'
    }
}

//if you need to get the position or angles of an entity instead of client (GetClientAbsOrigin only works on clients), you would do something like this.
Get_Entity_Position(entity)
{
    new Float: origin[3];
    new Float: angles[3];
    GetEntPropVector(entity, Prop_Send, "m_vecOrigin", origin);
    GetEntPropVector(entity, Prop_Data, "m_angRotation", angles);
} 


These were all found using the output of the various "sm_dump_*" commands.

sm_dump_datamaps datamaps.txt
sm_dump_classes classes.txt
sm_dump_netprops netprops.txt

should be all you really need, I think.
