Test 1

defineprojectile <tilenum> PROJ_WORKSLIKE <flag value>

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.

defineprojectile <tilenum> PROJ_SPAWNS <spawn tilenum>

Used to spawn an actor on impact.

Set <spawn tilenum> to -1 to spawn nothing, otherwise <spawn tilenum> defaults to SMALLSMOKE.

Doesn't work with bullet-type projectiles fired by actors other than the player.

defineprojectile <tilenum> PROJ_SXREPEAT <spawn xrepeat>

Used to set the x size of an actor spawned on impact.

Where <spawn xrepeat> is the size you wish to set the spawned actor's x to.

Test 2

PROJ_WORKSLIKE	Used to set flags for projectile function. Add all the desired flags together, and use that value for <flag value>. This works similar to cstat. 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.
PROJ_SPAWNS	Used to spawn an actor on impact. Set <value> to -1 to spawn nothing, otherwise <value> defaults to SMALLSMOKE. Doesn't work with bullet-type projectiles fired by actors other than the player.
PROJ_SXREPEAT	Used to set the x size of an actor spawned on impact. <value> is the size you wish to set the spawned actor's x to.
PROJ_SYREPEAT	Used to set the y size of an actor spawned on impact. <value> is the size you wish to set the spawned actor's y to.
PROJ_DECAL	Used to set the tilenum of any decal spawned by the projectile, i.e. bullet holes. <decal tilenum> is the tilenum of the decal used. Only works with bullet projectiles. Doesn't work with bullet type projectiles fired by actors other than players.
PROJ_TRAIL	Used to set the tilenum of any trail sprites spawned. <trail tilenum> is the tilenum of the trail sprites spawned.
PROJ_TXREPEAT	The x size of the trail used by the projectile. Note that if the trail is an actor with a size specified in its code (e.g. by a sizeat command) then the specified size will override the one you give it.
PROJ_TYREPEAT	The y size of the trail used by the projectile. Note that if the trail is an actor with a size specified in its code (e.g. by a sizeat command) then the specified size will override the one you give it.
PROJ_TOFFSET	The y offset of the trail spawned by the PROJ_TRAIL variable. Positive numbers move the sprite down.
PROJ_TNUM	The maximum number of trails that an individual projectile can spawn. By default, RPG (non-hitscan) type projectiles will spawn trails even if TNUM is not set. But bullet type (hitscan) projectiles will not spawn any trails unless TNUM is given a non-zero value. The way it works, is that if TNUM value is set to 2, then it will spawn 2 of the sprites on the same location. The default value is 1 if a trail is set for the projectile.
PROJ_SOUND	Used to play a sound when a projectile is fired. For bullet projectiles this is the sound played on impact. <fire sound> is the name of the sound you wish to play.
PROJ_ISOUND	Used to play a sound when a projectile impacts a surface. This is ignored on bullet-type projectiles. <impact sound> is the name of the sound you wish to play. Set PROJ_ISOUND to -1 to disable impact sounds.
PROJ_VEL	Used to set the velocity of a projectile. <velocity> is the speed of the projectile. Values over 1000 are not encouraged. Use PROJ_VEL_MULT to go at higher speeds.
PROJ_VEL_MULT	Used to set multiply velocity of a projectile (causes an artificial acceleration). <velocity multiplier> is the amount to multiply by. On a given tic the projectile will move PROJ_VEL_MULT times, for example, if you set PROJ_VEL_MULT to 1, it will only move at its current velocity (stored in its sprite's xvel / zvel) once per tic.
