FRIENDLY
This monster doesn't target the player.

Does this mean that any actor with this flag is automatically a monster? If not, what would setting this flag on a non-monster actually do?

[edward850]

It will only target non-friendly monsters, but not automatically. It still need to be awoken by the player (or other means).

I been wanting to ask involving sprites, how would you make a sprite 16:9 compatible? As I've been trying to make 2 weapons a Marathon-like weapon and the Duke43 GL but sadly they are only for 4:3 so they get cut off

You can use this flag with any actor, not necessarily with monsters. Any actor with this flag will get a visible [edit]HOSTILE MONSTER[/edit] as target when it calls an A_Look, for example.

No, the flag only makes something friendly. It's just that it's not really useful to put it on something that isn't a monster: a friendly medikit will not behave in any way differently from a normal medikit.

Does A_ChangeFlag remove flags as well?

I kinda wanted to utilize the wound state to give bosses +Missileevenmore at half-health, but I don't want them to have both +Missile and +Missileeven

[Blue Shadow]

Yes. For example, if you do this: A_ChangeFlag("<flag_name>", TRUE), you set the flag. And if you do this: A_ChangeFlag("<flag_name>", FALSE), you clear/remove the flag.

Oh ok, I didn't know it was a true or false sort of thing

All the wiki says is that it's a "value" so I got confused http://zdoom.org/wiki/A_ChangeFlag

No, but it will feel friendlier. It's all in the feel, man.

It clearly says "bool value". What is a boolean if not a true or false value?

[Toberone]

Well, I guess I learned something new today.

This is both humorous and informative, thanks for the info.

Hey, I'm trying to get a ReFire state going for a CustomInventory item to check if the player's holding down the itemuse button.
Unfortunately, GetPlayerInput doesn't have an ItemUse button.

Can I force-map BT_User1 to the itemuse key across players, or am I stuck here?

Thanks!

[edward850]

You're stuck, because "itemuse" (invuse) isn't player input to start with. Inventory usage (and weapon selection by extension) processes the name of the inventory you want to use. This is regardless if it's actually the "selected" inventory or not (see the use ccmd).
The invuse key is nothing more then a console command that processes whatever happens to be selected at the time.
