A_Chase flag; wandering movement

I'm trying to make an enemy that acknowledges that it's chasing the player and should attack him, but wanders normally rather than chasing him, as if calling A_Wander. Can a flag be added to allow mindless wandering in A_Chase?
Edit:
I would suggest the name CHF_WANDER.

I like this idea. A monster could stop to shoot at the Player, but still move erratically (like the bats in those games
).

Yeah.
This is meant for "friendly" marines who you can piss off, but they don't actively seek the player. Just shoot him on sight and keep on with their business.

A_Wander with 0-length A_Jump statements could fake it fairly well, I think.
Code: Select all
actor newzombie : zombieman replaces zombieman
{
States
{
See:
POSS AABB 4 A_Wander
POSS CCDD 4 A_Wander
TNT1 A 0 A_JumpIfTargetInLOS("Missile",360)
loop
Missile:
TNT1 A 0 A_Jump(128,"See")
POSS E 10 A_FaceTarget
POSS F 8 A_PosAttack
POSS E 8
goto See
}
}
Seems to work "okay".

One notable problem with that: It would be unaffected by MapInfo's ability to modify monster agressiveness.

Does anybody actually make use of that anyways?

I do. It's awesome for increasing the difficulty without boosting the Health of monsters to ridiculous levels.

I use it for skill settings.

You may want to call A_Chase/A_Stop more often though because it may not be aggressive enough.

Why the A_Stop calls? A_Chase has a CHF_DONTMOVE flag that will prevent the actor from moving.

Oh, that's even better then. Should make the code shorter. If only you could combine functions

I agree it would allow for much smoother movement.

Isham, quite a bump.
@Cutman: A_Stop wouldn't affect movement from A_Chase, since A_Chase movement is more akin to teleporting (it moves the actor's Speed every time it's called). Also, this would work better:
Code: Select all
See:
POSS A 0 A_Chase("", "Missile", 16)
POSS A 4 A_Wander
POSS A 0 A_Chase("", "Missile", 16)
POSS A 4 A_Wander
POSS B 0 A_Chase("", "Missile", 16)
POSS B 4 A_Wander
POSS B 0 A_Chase("", "Missile", 16)
POSS B 4 A_Wander
POSS C 0 A_Chase("", "Missile", 16)
POSS C 4 A_Wander
POSS C 0 A_Chase("", "Missile", 16)
POSS C 4 A_Wander
POSS D 0 A_Chase("", "Missile", 16)
POSS D 4 A_Wander
POSS D 0 A_Chase("", "Missile", 16)
POSS D 4 A_Wander
Loop
The 16 in the A_Chase is the CHF_DONTMOVE flag. This gives the wandering movement, but should attack as normal.
