> It's been quite a while since I posted last. I'm working on a new character, and I'm almost done with it, but I'm having trouble with one of the super attacks. A projectile drops from the sky and is supposed to land on the ground, then disappear after a second. However, the projectile instead disappears just before hitting the ground. Here's the code for the Projectile state controller...

[State 3100, Projectile]
type = Projectile
trigger1 = AnimElem = 8 ;kicks in when animation reaches its eighth frame
attr = S, HP ;Attributes (Standing, Super Projectile)
damage = 180, 18 ;Damage points to deal
getpower = 0, 0
givepower = 180, 18
guardflag = MA ;Can be blocked by standing or aerial opponent
ground.type = High ;opponent goes into hit high animation
animtype = Hard ;opponent goes into hit hard animation
ground.hittime = 10 ;opponent recovery time
ground.velocity = 0 ;how fast grounded opponent slides back
ground.slidetime = 1 ;how long opponent slides back
air.velocity = 0, 5 ;how fast aerial opponent slides back
fall = 1 ;knocks down opponent
sparkno = -1 ;displays no spark
palfx.add = 250, 0, 0 ;opponent turns red
palfx.sinadd = 120, 60, 60, 10 ;opponent's flashing effect
palfx.time = 30 ;opponent's color change effect lasts for 30 ticks
hitsound = S0, 7 ;plays Slam - Normal (sound effect)
guardsound = S0, 10 ;plays Hard hit - Blocked (sound effect)
ProjID = 3161 ;ID number of projectile
projanim = 3161 ;projectile animation (sprites)
;projhitanim = 3271 ;projectile spark (sprites)
projremove = 0 ;does not self destruct after hit
projremovetime = 60 ;projectile self destructs automatically after 60 ticks
velocity = 0, 5 ;how fast projectile moves
;remvelocity = 0, 0 ;how fast spark moves while it self destructs
accel = 0, 1 ;changes velocity of projectile
projhits = -1 ;number of times projectile hits before it self destructs
postype = p2
offset = 0, -500 ;adjusts the projectile's origin 500 pixels directly above opponent
afterimage.length = 10 ;after image lags 50 ticks above anvil
afterimage.time = 20 ;after image lasts for 20 ticks

Try using projheightbound instead of removetime.

> Thanks for the advice, Phantom. I replaced "projremovetime = 60" with "projheightbound = -100, 100", and now the projectile simply passes through the ground instead of just disappearing in mid-air. Now, I just have to figure out how to get it to stop when it hits the ground, then disappear after a second. Is this something that can be done with a projectile, or do I need to use a helper for that?

I think your settings of -100, 100 will make it disappear 100 pixels below the ground, which is why you wouldn't see it. But yeah if you want a very specific behavior for it you may need a helper.

> OK, I fixed the problem. All I had to do was switch from using a projectile to using a helper instead. I replaced the projectile code with this...

[State 3100, Helper]
type = Helper ;type of state: Helper
trigger1 = AnimElem = 8 ;kicks in when animation reaches its eighth frame
PosType = p2
Pos = 0, -500 ;adjusts the projectile's origin 500 pixels directly above opponent
StateNo = 3161 ;projectile's custom state


> And then used the following code for the helper...

; Anvil Gag - Projectile

[Statedef 3161]
physics = N ;switches to neutral physics
movetype = A ;activates red hitboxes
juggle = 4 ;attack costs 4 juggle points
anim = 3161 ;helper appears as Anvil Gag - Projectile (sprites)
velset = 0, 5 ;how fast projectile moves

[State 3161, Velocity Multiply]
type = VelMul
trigger1 = Time = 0 ;kicks in immediately
y = 5 ;Projectile accelerates downward

[State 3161, After Image]
type = AfterImage
trigger1 = AnimElem = 1 ;kicks in when animation reaches its first frame
length = 10 ;after images lags 10 ticks behind projectile
time = 20 ;after images last for 20 ticks

[State 3161, HitDef]
type = HitDef
trigger1 = Time = 0 ;kicks in immediately
attr = S, HP ;Attributes (Standing, Super Projectile)
damage = 180, 18 ;Damage points to deal
getpower = 0, 0
givepower = 180, 18
hitflag = MAFD ;Can hit standing, aireal, falling, and lying down opponent
guardflag = MA ;Can be blocked by standing or aerial opponent
ground.type = High ;opponent goes into hit high animation
animtype = Hard ;opponent goes into hit hard animation
ground.hittime = 10 ;opponent recovery time
ground.velocity = 0 ;how fast grounded opponent slides back
ground.slidetime = 1 ;how long opponent slides back
air.velocity = 0, 5 ;how fast aerial opponent slides back
fall = 1 ;knocks down opponent
sparkno = -1 ;displays no spark
hitsound = S0, 8 ;plays Slam - Super (sound effect)
guardsound = S0, 10 ;plays Hard hit - Blocked (sound effect)

[State 3161, Velocity Set]
type = VelSet
trigger1 = Pos Y >= -5
;^kicks in if projectile is 5 pixels above the ground or lower^
x = 0 ;Projectile does not move horizontally
y = 0 ;Projectile does not move vertically

[State 3161, Play Sound]
type = Playsnd ;type of state: Play Sound
trigger1 = Pos Y >= -25
;^kicks in if projectile is 25 pixels above the ground or lower^
trigger1 = Vel Y > 0 ;kicks in if projectile is not falling
trigger1 = P2MoveType != H
value = S0, 8 ;plays Slam - Super (sound effect)

[State 3161, Environment Shake]
type = EnvShake ;Shakes the screen
trigger1 = Pos Y >= -25
;^kicks in if projectile is 25 pixels above the ground or lower^
trigger1 = Vel Y > 0 ;kicks in if projectile is not falling
Time = 30 ;Screen shakes for 30 ticks
Ampl = -5 ;How far up & down the screen shakes
Freq = 100 ;How fast the screen shakes

[State 3161, Destroy Self]
type = DestroySelf ;type of state: Destroy Self
trigger1 = Time = 80 ;kicks in after 80 ticks into the animation


> The attack does everything I want it to do, except for two things. One, I couldn't get the PalFX to work, but there's a chance I'll try again later. And two, I need a whistle sound, but I'll probably include one in the second version of the character. Thanks for all your help, and I can now mark this topic as Solved.
