Hello everyone, I'm somewhat new to Pawn, and I'm getting an error while working entities when I use GetEntProp.

The error looks like this in the console / SM logs:

[SM] Native "GetEntProp" reported: Entity -1 (-1) is invalid

I'm hooking SDKHook_Spawn for tf_projectile_rocket.

I'm then using GetEntProp, to get the owner of the rocket:

//Condition is true if the rocket's owner's rocket launcher is level 101 (normally impossible to get unless using asherkins TF2 items extention)
if( IsClientInGame(iOwner) && IsPlayerAlive(iOwner) &&  GetEntProp(GetEntPropEnt(iOwner, Prop_Send, "m_hActiveWeapon"),  Prop_Send, "m_iEntityLevel") == 101)

And that's where I'm getting that error. Anyone have any pointers? Is there a condition that i should be checking for before calling GetEntProp?

Also, I just want to clarify, the above DOES work, however my console gets spammed with that error sometimes (it's either spamming like crazy, or not at all).

PHP Code:

if( IsClientInGame(iOwner) && IsPlayerAlive(iOwner) )
{
    new Weapon = GetEntProp(iOwner, Prop_Send, "m_hActiveWeapon");
    if( Weapon != -1 &&  GetEntProp(Weapon,  Prop_Send, "m_iEntityLevel") == 101 )
    {
        // Do stuff
    }
} 


You have to check "weapon" does not equal -1 is what the error is telling you.

GetEntPropEnt is for getting an entity index from a client (something like that, someone can hopefully elaborate) so use GetEntProp instead... as above.

OhhH!! Okay, I'm assuming it would = -1 if they fired a rocket, then died before the hook on the rocket entity is killed or something like that. I didn't understand where the -1 was coming from though. Thanks Silvers, I'll use GetEntProp instead!

GetEntPropEnt is to get the index of an entity handle (the 'h' properties). You above code was correct other than that you needed to check to see if there was a valid weapon. -1 is invalid entity, commonly used as "none" like in m_hActiveWeapon or m_hOwnerEntity.
