Trying to make a "GhostSphere" pick-up

[Empyre]

I am trying to make a replacement for the BlurSphere that makes the player partially invisible, but also makes him not solid and gives him NoTarget, all for 120 seconds. Here's the DECORATE code:

Code: Select all

ACTOR GhostSphere : CustomInventory replaces BlurSphere
{
  +COUNTITEM
  +INVENTORY.AUTOACTIVATE
  +INVENTORY.ALWAYSPICKUP
  +INVENTORY.BIGPOWERUP
  Inventory.MaxAmount 0
  RenderStyle "Add"
  Alpha 0.95
  Inventory.PickupMessage "You will be a ghost for a while!"
  States
  {
  Spawn:
     PINS ABCD 6 Bright
     Loop
  Pickup:
    TNT1 A 0
    TNT1 A 0 A_ChangeFlag ("NoTarget", True)
    TNT1 A 0 A_SetTranslucent (0.50, 1)
    TNT1 A 4095 A_ChangeFlag ("Solid", False)
    TNT1 A 105 A_Log ("WARNING! Your time as a ghost is almost over!")
    TNT1 A 0 A_Log ("You are not a ghost any more.")
    TNT1 A 0 A_ChangeFlag ("NoTarget", False)
    TNT1 A 0 A_SetTranslucent (1.0, 0)
    TNT1 A 0 A_ChangeFlag ("Solid", True)
    stop
  }
}

It prints the two A_Log messages before it even prints the pickup message, so the effect has zero duration, so I can't even find out if the effect even works.

All Pickup states have zero tic duration regardless of what you specify.

You need ACS.

You can use that PowerTargeter, it will maybe help you, here is an example:

Code: Select all

ACTOR MedPack : CustomInventory
{
Inventory.MaxAmount 1
Inventory.Icon "I_MBPK"
Inventory.PickupMessage "Medical Backpack"
Inventory.PickupSound "pickups/pmedkit"
Inventory.UseSound "pmed/use"
+INVBAR
States
{
  Spawn:
	MBPK A -1
    Stop
  Use:
	TNT1 A 1 A_GiveInventory("MedPackHealing",1)
	Stop
}
}

Actor MedPackHealing : PowerupGiver
{
    Powerup.Type MedPackHeal
    +AUTOACTIVATE
    +ALWAYSPICKUP
}

Actor PowerMedPackHeal : PowerTargeter
{
    Powerup.Duration -20
    States
    {
    Targeter:
        TNT1 AA 0
		TNT1 A 0 HealThing(2,150)
		TNT1 AAAAAA 3 A_SpawnItemEx("HealingEffect",random(24,-24),random(24,-24),random(0,32),0,0,random(1,4),0,128,0)
        Loop
    }
}

Ooooh, I like that! Thanks, Blood!

What I am wondering now is how can I use this to turn the effect on and then turn it off after the time elapses?

Glad to see my hacky code got some use.

I never tested the code with A_ChangeFlag specifically, but you can use A_GiveInventory at certain tics in the PowerTargeter to toggle the effects you want (assuming A_ChangeFlag does not work with PowerTargeter).

I was unable to get this to work. I wound up settling for giving the player 2 minutes of partial invisibility (with the cantseek flag), frightener, speed, and protection (taking only 33% of normal damage, with the noradiusdamage, dontrip, and nopain flags). It isn't what I wanted, but it is still a pretty good power-up. I might decide to add flight as well.

I might learn ACS some day, but for now, I am learning DECORATE.
