defineprojectile <tilenum> <function> <value>

Defines a projectile to be fired by the [[shoot]] command and its variants.

To use this command, several things must be done.  First, include the following defines somewhere before your defineprojectile lines:

define [[PROJ_WORKSLIKE]] 1

define [[PROJ_SPAWNS]] 2

define [[PROJ_SXREPEAT]] 3

define [[PROJ_SYREPEAT]] 4

define [[PROJ_SOUND]] 5

define [[PROJ_ISOUND]] 6

define [[PROJ_VEL]] 7

define [[PROJ_EXTRA]] 8

define [[PROJ_DECAL]] 9

define [[PROJ_TRAIL]] 10

define [[PROJ_TXREPEAT]] 11

define [[PROJ_TYREPEAT]] 12

define [[PROJ_TOFFSET]] 13

define [[PROJ_TNUM]] 14

define [[PROJ_DROP]] 15

define [[PROJ_CSTAT]] 16

define [[PROJ_CLIPDIST]] 17

define [[PROJ_SHADE]] 18

define [[PROJ_XREPEAT]] 19

define [[PROJ_YREPEAT]] 20

define [[PROJ_PAL]] 21

define [[PROJ_EXTRA_RAND]] 22

define [[PROJ_HITRADIUS]] 23

define [[PROJ_VEL_MULT]] 24

define [[PROJ_OFFSET]] 25

define [[PROJ_BOUNCES]] 26

define [[PROJ_BSOUND]] 27

define [[PROJ_RANGE]] 28


Second, we must figure out a proper WORKSLIKE flag for our projectile.  The WORKSLIKE flag can be determined by looking at the following defines:


define [[WORKSLIKEBULLET]] 1

define [[WORKSLIKERPG]] 2

define [[WORKSLIKEBOUNCESOFFWALLS]] 4

define [[WORKSLIKEBOUNCESOFFMIRRORS]] 8

define [[WORKSLIKEKNEE]] 16

define [[WORKSLIKEWATERBUBBLES]] 32

define [[WORKSLIKENOENEMYHITS]] 128

define [[WORKSLIKESPIT]] 256

define [[WORKSLIKECOOLEXPLOSION1]] 512

define [[WORKSLIKEBLOOD]] 1024

define [[WORKSLIKELOSESVELOCITY]] 2048

define [[WORKSLIKENOAIM]] 4096

define [[WORKSLIKERANDDECALSIZE]] 8192

define [[WORKSLIKEEXPLODEONTIMER]] 16384

define [[WORKSLIKEIMPACTDAMAGE]] 32768


To determine the proper WORKSLIKE flag for your projectile, simply add the numbers for the various functions you'd like your projectile to have together.  Obviously, some flags are not compatible.


Here is an example of a working user-defined projectile:

defineprojectile 1653 [[PROJ_WORKSLIKE]] 6150

defineprojectile 1653 [[PROJ_SPAWNS]] EXPLOSION2

defineprojectile 1653 [[PROJ_VEL]] 1000

defineprojectile 1653 [[PROJ_EXTRA]] 300

defineprojectile 1653 [[PROJ_DROP]] -200

defineprojectile 1653 [[PROJ_ISOUND]] PIPEBOMB_EXPLODE

defineprojectile 1653 [[PROJ_HITRADIUS]] 2560

defineprojectile 1653 [[PROJ_BOUNCES]] 5

defineprojectile 1653 [[PROJ_OFFSET]] 224

defineprojectile 1653 [[PROJ_CLIPDIST]] 24

defineprojectile 1653 [[PROJ_TRAIL]] SMALLSMOKE


In this example, the projectile has the following WORKSLIKE flags set: WORKSLIKENOAIM, WORKSLIKELOSESVELOCITY, WORKSLIKERPG and WORKSLIKEBOUNCESOFFWALLS.  This gives us an RPG-like projectile that doesn't automatically aim at enemies/players (we need this because the projectile in question fires in an arc), automatically slows down during flight, fires like an RPG and bounces off the walls.

Please take care not to set a projectile's velocity over 1000.  Instead, set PROJ_VELMULT and a lower PROJ_VEL.
