Set up an array in DECORATE?

[Ceeb]

How exactly do you define an array for an actor? Is it the same as setting up a user variable?

[Gez]

Yes. See [wiki]DECORATE expressions[/wiki]

• User Variables — user variables are defined as "var int user_(name);" in actor properties
• User Arrays — user arrays are defined as "var int user_(name)[(size)];" in actor properties

Oh. Not where I expected it to be! Thank you Gez.

Must be doing something wrong... Are DECORATE arrays started at zero? Sometimes the ball will curve, sometimes it flies straight. It should curve the other way...

Code: Select all

ACTOR LightBeamProjectile
{
    Radius 8
    Height 8
    Speed 20
    Damage 8
    Scale 0.4
    Projectile
    Renderstyle Add
    Alpha 0.6
    +RIPPER

    var int user_weave;
    var int user_weavearray[2];

    States
    {
    Spawn:
        TNT1 A 0 A_SetUserArray("user_weavearray",0,-2)
        TNT1 A 0 A_SetUserArray("user_weavearray",1,2)
        TNT1 A 0 A_SetUserVar("user_weave",user_weavearray[random(0,1)])
    Flying:
        LBPR A 1 A_SpawnItemEx("LightBeamProjectileTrail")
        TNT1 A 0 A_Weave(user_weave,user_weave,1.0,1.0)
        Loop
    Death:
        TNT1 A 0
        Stop
    }
}

You simply forgot about the Curse Of The Spawn State(tm): an actor only runs its action function when it transitions to a new state, and thus does not run the code from its spawn state...

Crap! I usually tend to be good about that. Thank you Gez...
