Moving Monsters without changing state.

[mallo]

What letters in state are allowed? (MEEN A 4)
Beacuse i created this monstrosity:

Code: Select all

MeenSpeen:
LOAD "ABCDEFGHIJKLMNOPQRSTUVWXYZ[];<>,?!{}\|@#$%^&*(" 4
Goto See

And this shows me this error:

Script error, "dinner~1.wad:DECORATE" line 97:
Invalid frame character string 'ABCDEFGHIJKLMNOPQRSTUVWXYZ[];<>,?!{}\|@#$%^&*('

There's nothing about it on wiki (And about using letters like [ or ;, i had to look in zdoom.pk3 for this)

[Popsoap]

All letters from A-Z are allowed. "[", "\", and "]" are also valid provided they are enclosed in quotation marks.

Okay, thanks! Thankfully, i know what to do.

EDIT: Another question - I want to make enemy move a bit to the right, and a bit to the left. I don't know how. I don't know how to use A_ChangeVelocity (Or something like that)

[Mr. Tee]

I'm assuming you don't want to use the CHF_FASTCHASE property in A_CHASE which has the monster strafe left and right around the player?

If not, you can use THRUSTTHING in an ACS script if you want it to move left and right at specific intervals (or random intervals depending on how the script is written).

Finally, here's how one could use A_CHANGEVELOCITY to do what you desire:

See:
SPRT A 4 A_ChangeVelocity (0, 12, 0, CVF_RELATIVE)
SPRT B 4 A_ChangeVelocity (0, -12, 0, CVF_RELATIVE)
Goto See

http://zdoom.org/wiki/A_ChangeVelocity

(someone correct me if this is wrong, I don't have ZDoom on this computer)

In this example, a monster's SEE state has two A_ChangeVelocity functions which alter the y-axis velocity (i.e. actor's left and right movement) by 12 units first in one direction, and next in the other direction. The constant CVF_RELATIVE ensures that the velocity will change according to the angle the actor is facing, as opposed to absolute map coordinates.
