Blue Shadow

Since the player doesn't move like other creatures in the game, the speed you set there is a multiplier. For instance, a value of 0.5 cuts the speed in half. For the pointer thing, don't worry about it, you can omit it.

A_SetSpeed, obviously, can be used to change the speed of an actor. You can call it from a weapon. It works.

As a player, I like to be given the freedom and choice of how to solve a problem. Also, can we stop talking about cheese? :P

In ZDoom, it is changed by using 'borderflat' in a MAPINFO's gameinfo block. https://zdoom.org/wiki/MAPINFO/GameInfo_definition Wheher that works in those other ports or not is something I do not know.

What are these steps you're trying to repeat?

Yes, revenants and archviles, here too. Pain elementals? No. I just plain dislike them.

I don't like quantifying this sort of things. So I'm fine with it gone.

No, there isn't.

You have to be careful with ClearInventory(), since it doesn't just remove weapons.

I don't have or own many games, and with Doom, I just like it, and I can mod it as a bonus.

This might work: https://zdoom.org/wiki/GetLevelInfo (check the example).

With SetActorProperty, use APROP_SpawnHealth as the property. https://zdoom.org/wiki/ACS_actor_properties

You can, but you need to specify the path to the file along with its extension: imp/melee "sounds/path/to/sound/impmeleeattack.ogg"

Then educate yourself.
