Universal script to make any monsters have fall damage?

[Spaceman333]

Some newer mods feature the ability to "push" monsters via weapons, abilities or items, so I'd love to have a universal addon script that would apply fall damage, so I could have monsters actually die or get hurt when pushed off a cliff. Only the monsters, not the player though.

I also want to know if applying floor damage - liquids or floors that usually hurt the player - can also be applied to monsters too.

I'm new to zScript, so I want to ask how to go about making this work, or if it even is possible?

You can set up an event handler to automatically give all monsters a special item.
In that item you can override DoEffect() to create a custom function of dealing fall damage.
For example:

---

Code: Select all

version "3.0"

Class FallingHandler : EventHandler
{
    Override void WorldThingSpawned(WorldEvent e)
    {
        If(!e.Thing.FindInventory("FallingItem") && e.Thing.bISMONSTER) //If a monster is a monster and lacks the item
        {
            e.Thing.A_GiveInventory("FallingItem",1); //Give it to them
        }
    }
}

Class FallingItem : Inventory
{
    double oldvel;
    double curvel;
    Override void DoEffect()
    {
        Super.DoEffect();
        curvel = owner.vel.z; //Store current velocity
        If(oldvel < curvel) //If previous velocity is lower than the current one, which can only happen when the monster hits the floor and gets to 0 current velocity
        {
            If(oldvel <= -16) //If the previous velocity is less or equal to 16, from the Falling Damage wiki page that translates into 128 units
            {
                int dam = (int)(oldvel); //Set the damage, you can do some math operations to tweak it
                owner.DamageMobj(null,null,-dam,"Falling"); //Deal the damage
            }
        }
        oldvel = owner.vel.z; //Store previous velocity
    }
} 

Remember that you also have to specify this in MAPINFO:

Code: Select all

GameInfo
{
    AddEventHandlers = "FallingHandler"
}
