Okay question.

Do you want these blasts to be homing?


I have something in mind.. But I kinda need to have that at least  cleared up

Alright well first things first. we are going to create a series of helpers.

Im assuming this is a dbz character?

C= Character H1=Helper 1  B1=Blast 1 B2=Blast 2



Now... you can basically use these 3 helpers over and over again.

so to start your coding should look like this.

Code:

[StateDef 710,Call Striker]
type                           = S
movetype                       = A
physics                        = S
juggle                         = 5
poweradd                       = 0
ctrl                           = 0
velset                         = 0,0
anim                           = 195 ; you can change this to any number you like, just make sure you change any other number with the same statedef
sprpriority                    = 0



[State 715, H1]
type                           = Helper
trigger1                       = time=50 ;<--this means that the helper will appear after the parent has been in anim 195 for 50 ticks
id=710
helpertype                     = normal
name                           = "H1"
stateno                        = 715 ; make sure the numbers here, matches the numbers on the helpers statedef
BINDTIME                       = 300
removeongethit                 = 1
pos                            = -10,0
postype                        = p1
sprpriority                    = -4



[State 710, 4]              ;<---This is where your character will go into another state to proceed with the attack
type                           = ChangeState
trigger1                       = animtime=0
value                          = 1232 ;<----Use any number you like here
ctrl                           = 0


;Now for the helper itself



;-------------------------------------------------------------------------------
; h1
[Statedef 715]
type                           = S
movetype                       = A
physics                        = N
juggle                         = 15
airjuggle                      = 15
poweradd                       = 0
velset                         = 0,0
anim                           = 2555 ; you can change this to any number you like, just make sure you change any other number with the same statedef
ctrl                           = 1
sprpriority                    = 4

;Helpers are basically characters themselves so add in explods, projectiles, and any other crap you can think of here.

[State 715, 4]   ;<---This part is optional.. This would be to make the helper go into another state
type                           = ChangeState
trigger1                       = animtime=0
value                          = 717
ctrl                           = 0


[State 718, Destroy]   ;<---Whenever your helper is done doing what it was supposed to do. Put this at the end of its last state
type                           = DestroySelf
trigger1                       = animtime = 0

Huh? I thought everything here was self exclamatory Do you not understand the way the .air file works or something?

Scatter shot :
1.create as many helpers as you want to fire. You can create them all at once or during a time interval one at a time, spread out by persistent=x, whichever you prefer.
2.generate a random number in the helper's code, store it in a variable
3. set X velocity to cos(your random number*pi/180) and Y to -sin(same). This spreads them to all 360 degrees, if you want only a certain range of angles, limit the random number into that range.
4. If the stuff you shot has a front side (usually it will unless it's just a simple ball shaped thing), you should turn it towards the direction it is moving, using angledraw. The angle is already in the variable you generated, or you can copy the code that turns it to the correct direction matching the velocities from my characters. The latter will work even if it changes directions later.
Example code : My Cirno's 99 Needles spellcard (all directions) or Patchouli's Watergun (forward only), and lots of others.

Striker :
1. Create a helper, it will be the striker
2. Make sure it cannot be hit, or define what should happen to it using a hitoverride if you prefer it to get hit.
3. Make the helper do the stuff you listed as though you were coding a normal character to do the same. It's not any different. A helper is essentially an extra copy of your character with its own state/animation/etc.
4. Use destroyself to remove the helper when done.
...But if you are making a Touhou character, you should have used lots of helpers for your projectiles and know all of this already.

[State 1100]
type = Explod
trigger1 = AnimElemTime(5) >= 0
trigger1 = Random%2 = 0
anim = 1105 ;+ Random%4
ID = 1105
pos = -6+Random%25,-48+Random%25
postype = p1
bindtime = 1
removetime = -2
ownpal = 1

accel = 0.01*var(1), 0.01*var(2)
ignorehitpause = 1
trans = add

Anyways, yes it can be accomplished with helpers, but you have to replicate the behavior with statecontrollers instead of defining the velocities as parameters to the intial controller that creates the helper, as you would normally use for Explods. What you're looking for is the VelSet controller. When applying acceleration you'll need to apply it in the form of a velocity. Some knowledge of calculus is needed to convert acceleration into velocity but for those that aren't calculus-literate:

Acceleration = 0.001
Velocity = 0.001*time + constant

in other words, the accel parameters of the explod:

[mcode]vel = 0.1*var(1), 0.1*var(2)
accel = 0.01*var(1), 0.01*var(2)[/mcode]

.. need to be rewritten as:

[mcode][State XXX, VS]
type = velset
trigger1 = 1
x = 0.1*var(1)+0.01*var(1)*time
y = 0.1*var(2)+0.01*var(2)*time[/mcode]

Of course if you store time as a separate variable then that can be used as well. Also keep in mind that this uses the var(1) and var(2) values of the helper rather than the player creating the helper.

You didn't set var(1) and var(2) so you are setting your velocity to 0. Obviously it won't move.
Same goes for your var(0) at your changestate, it's 0 so it never triggers.
Helpers have their own variables, that start as 0 when the helper is created, and you never set them to any other value.
And if you want gravity, use Type=Gravity. And make sure to destroy your projectile when it hits the ground.

Helpers have their own variables, that start as 0 when the helper is created

Each helper has its own. If you create 7 fireball helpers, all 7 has its own var(0), with 7 different values (and all start at 0 first).
If you want to access the player's variables from a helper, you need to use the root redirection for that. Otherwise you are accessing the helper's variable.

[State 193001]
type = varrandom
trigger1 = 1
v = 1
range = -30, 15

[State 193001]
type = varrandom
trigger1 = 1
v = 2
range = 70, 110

vel=-vel x*(.25+random*.001),-vel y*(.25+random*.001)
accel=-vel x*.001,-vel y*.001

[State XXX, VS]
type = velset
trigger1 = 1
x = -vel x*(.25+random*.001)+-vel x*.001
y = -vel y*(.25+random*.001)+-vel y*.001

NOTE: When I added the veladd, it started moving, but very slowly and in both directions.
Since I took out the vars from the previous version, I doubt, it has something to do with missing variables...

Alternatively, I found this in an explod:

Code: (mugen)

vel=-vel x*(.25+random*.001),-vel y*(.25+random*.001)
accel=-vel x*.001,-vel y*.001

If I'm not wrong, then this can be turned for an helper into this:

Code: (mugen)

[State XXX, VS]
type = velset
trigger1 = 1
x = -vel x*(.25+random*.001)+-vel x*.001
y = -vel y*(.25+random*.001)+-vel y*.001

Am I right, or did I forgot something?

Wow, I didn't though about that. Thanks. However, I have now new questions:

Code: (mugen)

[State 193001]
type = varrandom
trigger1 = 1
v = 19
range = 0, (((random)^2)^0.5)

If I want to set the variable into a random positive number, does the above code work?
Thanks in advance!

EDIT: Okay, made a new start, and the stars are still going into both directions...

Code: (mugen)

[State 2105]
type = varrandom
trigger1 = 1
v = 19
range = 0, 1000

[State 2105]
type = velset
trigger1 = 1
x = 0.1*var(19)+0.01*var(19)
y = 0.2 * cos((.25+random*.005)*Pi/180)+-vel y*.005;-vel y*(.25+random*.005)+-vel y*.005

Is it, because the X position is something different then I thought?
