Help with Custom Function

Zephirius · April 2021

Can anyone help me out with a custom function that would emulate A dragons wing effect upon a PC? I'm talking EffectKnockdown() + possibly moving the PC as a result of the force of its wings. This is above my paygrade so I can only say thanks in response to my query ahead of time.

void HurricaneWing(effect eEffect)
{

object oPC = GetNearestCreature
(CREATURE_TYPE_PLAYER_CHAR, PLAYER_CHAR_IS_PC, OBJECT_SELF);

effect eEffect = EffectKnockdown();
eEffect = EffectVisualEffect(VFX_FNF_SCREEN_SHAKE);

ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eEffect, oPC);
ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eEffect, oPC);

}

void main()
{



}

Like I said, a little out of my wheelhouse...

I just found this on The Vault in case anone was interested. It's AI code written by Jasperre.

/************************ [Dragon Wing Buffet] *********************************
    Filename: J_AI_WingBuffet
************************* [Dragon Wing Buffet] *********************************
    "The dragon will launch into the air, knockdown
    all opponents who fail a Reflex Save and then
    land on one of those opponents doing damage
    up to a maximum of the Dragons HD + 10."

    This is modified by Jasperre for use by Dragons in the AI. Instead of
    crashing, using effect appear, disspear, it just uses effect appear.

************************* [History] ********************************************
    Version 1.3 changes
    - Made the "action attack" work better, getting the nearest
      seen and heard instead of the nearest (which may not be seen or heard).
    - Added in random damage for each target!
    - Faction Equal as well as GetIsFriend check.
************************* [Workings] *******************************************
    Executed via. ExecuteScript from the AI file, it is seperate because it is
    almost a new AI ability.

It's difficult to help because I don't really know what you want to do.

Do you want to use the script above but add the screen shake effect? Then simple add that effect if oTarget is a PC. Perhaps it's also possible to move oTarget (like it is in Baldur's Gate) but you have to make sure to not move oTarget through walls or so.

If you want to do something else you would have to explain that a little bit more (at least to me).
