Set angle for spawned missiles

[Heretic_Crossbowman]

Hello all!
I am trying to create a projectile that spawns another small projectiles around it in half circle.
I am trying to use that code

---

class PhoenixFX1N : Actor replaces PhoenixFX1
{
Default
{
Radius 11;
Height 8;
Speed 5;
Damage 20;
DamageType "Fire";
Projectile;
+THRUGHOST;
+SPECIALFIREDAMAGE;
SeeSound "weapons/phoenixshoot";
DeathSound "weapons/phoenixhit";
Obituary "$OB_MPPHOENIXROD";
}
States
{
Spawn:
FX08 A 1 Bright A_PhoenixFire;
Loop;
Death:
FX08 A 6 Bright A_Explode;
FX08 BC 5 Bright;
FX08 DEFGH 4 Bright;
Stop;
}
void A_PhoenixFire()
{
for (int i = 1; i < 8; i++)
{
Actor phoenixfire = Spawn("PhoenixFX2", Pos, ALLOW_REPLACE);
// shard.target = target;
phoenixfire.angle = i*22.5;
phoenixfire.VelFromAngle();
phoenixfire.Vel.Z = -.0;
phoenixfire.CheckMissileSpawn (radius);
}

So everything works right except that angle of small projectiles is based on absolute value and doesn't depend on movement vector of initial projectile. How can i solve that?

The curse of NoDelay strikes again!

That A_PhoenixFire is not being called. Try

Code: Select all

FX08 A 1 nodelay Bright A_PhoenixFire;

FX08 A 1 nodelay Bright A_PhoenixFire;

Tanks )) But as i understand NoDelay, i don't need it here because i WANT to spawn small projectiles all the way )
Question is how to orient them in the direction AWAY from player who shoots first projectile )))

I don't understand what those words mean in this context, but to take a guess at one thing they don't mean:

Without the "nodelay" in the first frame of a spawn state, nothing in that frame gets called. You will either need a frame just before it (could be zero-length), or the "nodelay" keyword.

For A_PhoenixFire to be called at all in the above code you either need the nodelay or this:

Code: Select all

FX08 A 0;
FX08 A 1 Bright A_PhoenixFire;

Mind the loop, Matt.

And for the angle, this should do the trick if the projectile you showed us has the correct angle.

Code: Select all

phoenixfire.angle = angle - 90 + i*22.5

So here is result of what i've made. Fiery "Fan" spawns around projectile, but its angle is constant due to world coordinates not to primary missile's vector of movement So it doesn't matter from which point i shot - orientation of additional projectiles is contant.

Maybe I am too dumb but I still don't understand what's wrong with angles of the missile trail. o_0

Or... are you looking for something like this? But actually I don't see any specific difference aside from fact that is seeker missile with transferred "static" pitch.

[Heretic_Crossbowman]

I've created a scheme ofwhat i want! ))
Blue point represents initial missile
Blue arrow represents it's vector of movement
Red arrows represent vectors of "child" missiles

Oh, got it!

So, if you still want to optimize it, then it still can be expressed as anon. func.:

Code: Select all

Speed 5
var float user_MAngle;
States
{
Spawn:
FX08 A 1 Bright NoDelay
{
	For(A_SetUserVarFloat(user_MAngle,-90); user_MAngle<90; A_SetUserVarFloat(user_MAngle,user_MAngle+22.5))
    {
        A_SpawnItemEx("PhoenixFX2",0,0,Height/2,10,0,0,user_MAngle,SXF_NOCHECKPOSITION|SXF_TRANSFERPITCH);
    }	
}
Loop
