Hi.
I'm making a bow that shoots arrows with bombs attached to them. I've got most of the features down, but I want to attach a stickybomb to the player where the arrow hit, so their team has an indication that he has a bomb on him, I better keep away from him!

Is it even possible?
Thanks for any replies that come through

Tracerays and Parenting would be the route to take.

Yeah, I'm lost. Like my signature says. I haven't been doing Sourcepawn for very long, and I learn off of other people's work rather than the wiki since I've had previous experience in coding.

PHP Code:

public Thing(whatever)
{
    decl Float:fEnd[3];
    new Handle:trace = TR_TraceRayFilterEx(cOrigin, cEyes, MASK_SHOT, RayType_Infinite, TraceRayDontHitSelf, client);
    if(TR_DidHit(trace))
    {
        TR_GetEndPosition(fEnd, trace); //Returns a vector with the ending position
        new entity = TR_GetEntityIndex(trace);
        /*   
        *    Teleport Stickybomb to fEnd and SetParent to the entity. Something like...
        *    SetVariantString("!activator");
        *    AcceptEntityInput(stickyBombEnt, "SetParent", entity);
        *    ...
        */
        CloseHandle(trace);
    }
}

public bool:TraceRayDontHitSelf(entity, mask, any:data)
{    
    if(entity == data)
    {
        return false
    }
    else if(entity != data && entity > 0 && entity <= MaxClients)
    {
        return true;
    }
    return true
} 


Additionally, you could check if entity was a player and use that index for parenting the stickybomb to the target.
Added to the code instead.

TR_TraceRayFilterEx

The easier route is to just hook SDKHook_StartTouchPost onto the entity "tf_projectile_arrow" at OnEntityCreated().
Then in StartTouchPost get the origin of where the arrow hit and spawn the sticky bomb there.

If you need an example code, take a look at my explosive arrows plugin. It creates a delayed explosion whenever an arrow hits someone which is similar to what your asking, except spawning an entity instead of exploding.

The code is 4 years old, so if you need a cleaner/better example, ask away.

Thanks. I have an idea of what I'm supposed to do after looking at your plugin. As for spawning the stickybomb and keeping it there I'm not sure what to do, as I believe if I spawn a normal stickybomb it will either flop to the ground or bounce off of the victim. And like abrandnewday said parenting the model to the player will result in it becoming invisible.

Parent the sticky to player to prevent it from falling down.
You can parent the sticky entity, just not a prop_dynamic entity.

[Chaosxk]

There are other entities like prop_static and tf_wearable that turns invisible.
I didn't test but I doubt the sticky entity would turn invisible.

Have you considered attaching the bomb to the arrow instead?

Are you sure you didn't mean prop_physics instead of prop_static? prop_static is a compile-time map entity that doesn't exist at runtime as it gets compiled into the map geometry.

Yep, writing on phone. I just know prop_* turns invisible if parented. Not sure about ragdoll though.
