Alternative attacks

[vinvin]

I'm currently working on my first Doom mod and i'm starting with new weapon logic. I'm trying to add alternative attacks for each weapon, like in Unreal Tournament, but i'm also looking into adding non-weapon specific attacks: punching, kicking and throwing a grenade. Are there any examples i can find where i can learn more about this non-weapon specific attack modes? Is there any specific changes needed for multiplayer? Where can i find more about bouncing projectiles, like grenades?

Look at the Decorate in complex-doom.v26a2.pk3 using Slade 3.

if by "alternative attack" you mean some "third" attack (FIRE being the "first" and ALTFIRE being the "second"), a_jumpifinventory mixed with ACS and KEYCONF is the key. First make an ACS that only gives you a special item, lets call it a "thirdattack", then make a KEYCONF that adds a new bind in the customize controls, executing that ACS (puke). And finally, make the Ready state of your weapon go TNT1 A 0 a_jumpifinventory("ThirdAttack",1,"ThirdFire")
with the first string of the ThirdFire state going a_takeinventory("ThirdAttack",999) followed by the attack of your choice.

If you are looking for a weapon able to make more than 2 attacks here is an example, hoping you will understand it.
