I will spawn an item with SPAWN(), but how do I assign a script to it? [SOLVED]

[Shkwarkel]

I create an item using the SPAWN command. The item spawns in front of the player at a distance of 100 on the x-axis. I want when the player picks up it a specific scpit is executed. Can you help me to do it? I think I need to use TID?

Not sure if possible purely with scripting. You could make a simple Medikit replacement actor that runs a script when picked up.

Off the top of my head....

 

assuming you are only spawning one  Medikit2 and only the player can pick it up (and it's single player...maybe)

 

int aTag = UniqueTID();

 

do{

  delay(1);

  int x = GetActorX(0) + 200.0;

  int y = GetActorY(0);

  int z = GetActorZ(0);

} until (Spawn("Medikit2",x,y,z,aTag,0));

 

//might want a delay here?

 

while ( ThingCountName("Medikit2", aTag) > 0 )
{
   delay(1);
}

 

//then put your wanted code here or ACS_Execute to start the desired script

 

 

Or do it in DECORATE, making the class execute a specified script on pickup.

Yeah, it works. Thank you so much. If it's not too much trouble, could you give me a link to a tutorial on how to assign a script to an object via DECORATE? I think I could really use it in my project.

The way I always done it is i placed a thing outside of the map with the dormant flag checked then teleport & Thing_Activate it instead of spawning

And it had the appropriate action already attached to it that upon picking it up/killing it if it sa monster the action is performed like open a door

I don't know of any tutorials. I tend to bash my head against the zdoom wiki until I figure things out. Failing that I go and find a mod that does what I want and then use that as an example.

 

I'm very rusty on some of this stuff, but I had a pickup in doom raider that executed a script. Here's the DECORATE code, you should hopefully figure it out from that.

 

ACTOR ProtectionAmulet : CustomInventory 19121
{
    Inventory.PickupMessage "Amulet of protection"
    Inventory.Icon "ST_AMUL"
    +INVENTORY.FANCYPICKUPSOUND
    +INVENTORY.ALWAYSPICKUP
    +COUNTITEM
    
    Inventory.PickupFlash none 

    States
    {
        Spawn:
            AMUL A 12 //Bright
            AMUL B 6
            Loop
            
        Pickup:
            TNT1 A 0 A_GiveInventory("ProtectionArmour",1)
            TNT1 A 0  ACS_NamedExecuteAlways("blueFlash", 0)
            Stop
    }
}

 

 

edit:

 

Try this

 

ACTOR Medikit2 : CustomInventory  
{
    Inventory.PickupMessage "myMessage"
    +INVENTORY.ALWAYSPICKUP
    
    States
    {
        Spawn:
            AMUL A 12 //change this to whatever your sprites are
            AMUL B 6
            Loop
            
        Pickup:
            TNT1 A 0 A_GiveInventory("Medikit",25) //assuming this is a medikit variant and you want the same effect
            TNT1 A 0  ACS_NamedExecuteAlways("myScript", 0)
            Stop
    }
}

 

...I seem to remember that only classses that inherit from CustomInventory can have pickup states. If I'm wrong then I'm overcomplicating the whole thing

I see what you mean. Thanks for your help.
