PROJ WORKSLIKE

defineprojectile <tile number> PROJ_WORKSLIKE <flag value>

PROJ_WORKSLIKE is a defineprojectile property used to set flags for projectile function.

Note that the damage on impact bit (32768) must be set on the WORKSLIKE of any RPG type projectile (i.e. nonhitscan) for which the projectile itself does damage, as opposed to the damage being caused only by the hitradius.

Add all the desired flags together, and use that value for <flag value>. This works similar to cstat.

Flags

The following values are used with defineprojectile.

Exposed	Value	Hex	Label	Description
Yes	1	0x000001	PROJECTILE_HITSCAN	Indicates that the projectile is hitscan. It cannot be applied simultaneously with PROJECTILE_KNEE, PROJECTILE_RPG, or PROJECTILE_BLOOD.
Yes	2	0x000002	PROJECTILE_RPG	Indicates that the projectile is a moving actor. It cannot be applied simultaneously with PROJECTILE_HITSCAN, PROJECTILE_KNEE, or PROJECTILE_BLOOD.
Yes	4	0x000004	PROJECTILE_BOUNCESOFFWALLS	Nounce off of all walls, like pipebombs and freezeblasts.
Yes	8	0x000008	PROJECTILE_BOUNCESOFFMIRRORS	Bounce off of mirrors only, like shrinker blasts and firelasers.
Yes	16	0x000010	PROJECTILE_KNEE	Indicates that the projectile is melee, essentially hitscan with limited range. It cannot be applied simultaneously with PROJECTILE_HITSCAN, PROJECTILE_RPG, or PROJECTILE_BLOOD.
Yes	32	0x000020	PROJECTILE_WATERBUBBLES	Spawn water bubbles (WATERBUBBLE, tile #661) if underwater.
Yes	64	0x000040	PROJECTILE_TIMED	If projectile is flagged as an RPG projectile, then this flag will make the projectile disappear. You have to define the projectile with PROJ_RANGE. 30 units = 1 second. Which is the ammount of time before the projectile will disappear. Keep in mind. If this flag is set, the projectile won't start the spawn option, sound options, and probably a few more options.
Yes	128	0x000080	PROJECTILE_BOUNCESOFFSPRITES	Bounce off of sprites.
Yes	256	0x000100	PROJECTILE_SPIT	Draw loogies on a player's screen and tint it green if the player is hit by the projectile.
Yes	512	0x000200	PROJECTILE_COOLEXPLOSION1
Yes	1024	0x000400	PROJECTILE_BLOOD	Indicates that the projectile is a blood splat, like the hardcoded BLOODSPLAT1 through 4 found in state random_wall_jibs. It cannot be applied simultaneously with PROJECTILE_HITSCAN, PROJECTILE_RPG, or PROJECTILE_KNEE.
Yes	2048	0x000800	PROJECTILE_LOSESVELOCITY
Yes	4096	0x001000	PROJECTILE_NOAIM	The projectile will not automatically aim at any targets
Yes	8192	0x002000	PROJECTILE_RANDDECALSIZE	If this flag is set in the PROJ_WORKSLIKE variable, then the projectile will randomize the size of its decals.
Yes	16384	0x004000	PROJECTILE_EXPLODEONTIMER	If projectile is an RPG with PROJECTILE_FLAG_TIMED flag set, then it normally wouldn't spawn sounds and more things. To prevent that, use this flag.
Yes	32768	0x008000	PROJECTILE_RPG_IMPACT	Setting this flag in the PROJ_WORKSLIKE variable means that the actors\players that are hit by the projectile will receive direct damage in addition to hitradius, making the total damage close to twice PROJ_EXTRA, similar to the hard-coded RPG projectile. The projectile will also add momentum with direct damage, which can be used in conjunction with setting PROJ_HITRADIUS to 0 in order to create an effect like shooting a rock, if you want it to be realistic.
Yes	65536	0x010000	PROJECTILE_RADIUS_PICNUM	This flag sets the projectile's picnum to its target's htpicnum instead of the default RADIUSEXPLOSION, or 1670.
Yes	131072	0x020000	PROJECTILE_ACCURATE_AUTOAIM
Yes	262144	0x040000	PROJECTILE_FORCEIMPACT
Yes	524288	0x080000	PROJECTILE_REALCLIPDIST	Allows the value of PROJ_CLIPDIST to take effect if set. Otherwise the hardcoded clipdist of 4 takes effect.
Yes	1048576	0x100000	PROJECTILE_ACCURATE
Yes	2097152	0x200000	PROJECTILE_NOSETOWNERSHADE
Yes	4194304	0x400000	PROJECTILE_RPG_IMPACT_DAMAGE
