}

This checks each time you pull a lever if all 4 have been pulled, and if so opens and unlocks the door called DOOR_To_OPEN. If not, it sets that lever to "pulled".

Clear?

Whoops. Change the last block to :

object oPC = GetLastUsedBy();
if (!GetIsPC(oPC)) return;
SetLocalInt(oPC, "leverone", 1);

Its an Int, not a sString

[Jamski]

Bleh, sorry, forget all that. This one is better :

//Created by Jamski
//Put this OnUsed for each lever
//(leverone, levertwo leverthree, leverfour)
//Make four copies, one for each lever
//Change the text in bold for each lever
//Call the door to be opened DOOR_TO_OPEN
//Best Version

void main()

{
object oPC = GetLastUsedBy();
if (!GetIsPC(oPC)) return;
SetLocalInt(oPC, "leverone", 1);
if (!GetIsPC(oPC)) return;
int nInt;
nInt=GetLocalInt(oPC, "leverone");
if (nInt == 1)
{
nInt=GetLocalInt(oPC, "levertwo");
if (nInt == 1)
{
nInt=GetLocalInt(oPC, "leverthree");
if (nInt == 1)
{
nInt=GetLocalInt(oPC, "leverfour");
if (nInt == 1)
{
object oTarget = GetObjectByTag("DOOR_TO_OPEN");
SetLocked(oTarget, FALSE);
AssignCommand(oTarget, ActionOpenDoor(oTarget));
}
}
}
}
}

Just tested this last one - it works PERFECTLY. Ok, the levers don't animate, but that's not my problem. Use buttons instead or add an animation

I couldn't get that one to work either.

Here is the script I've been using:

void main()
{

  object oPC=GetLastUsedBy();
  int nUsed1 = GetLocalInt(OBJECT_SELF, "LEVER_STATE");

  int nUsed2;
  int nUsed3;
  int nUsed4;
  //
  // nUsed1 and nUsed2 are used to temporarily hold the states of the two levers.
  // 0 is off, 1 is on
  // LEVER_STATE is the permanent holding spot for the variables.
  // Each lever stores its own LEVER_STATE
  //
  if(nUsed1 == 0)
  {
    ActionPlayAnimation(ANIMATION_PLACEABLE_ACTIVATE);
    SetLocalInt(OBJECT_SELF, "LEVER_STATE", 1);
    ActionSpeakString("You hear the sound of a metal pin being released.");
    PlaySound("as_sw_metalop1");
    nUsed1 = 1;
  }
  else
  {
    PlayAnimation(ANIMATION_PLACEABLE_DEACTIVATE);
    SetLocalInt(OBJECT_SELF, "LEVER_STATE", 0);
    ActionSpeakString("You hear the sound of a metal pin being reset.");
    PlaySound("as_sw_metalcl1");
    nUsed1 = 0;
  }

object oLever1=GetNearestObjectByTag("DLEVER1");
object oLever2=GetNearestObjectByTag("DLEVER2");
object oLever3=GetNearestObjectByTag("DLEVER3");
object oLever4=GetNearestObjectByTag("DLEVER4");


  nUsed1 = GetLocalInt(oLever1, "LEVER_STATE");
  nUsed2 = GetLocalInt(oLever2, "LEVER_STATE");
  nUsed3 = GetLocalInt(oLever3, "LEVER_STATE");
  nUsed4 = GetLocalInt(oLever4, "LEVER_STATE");

  string sUsed1=IntToString(nUsed1);
  string sUsed2=IntToString(nUsed2);
  string sUsed3=IntToString(nUsed3);
  string sUsed4=IntToString(nUsed4);

  SendMessageToPC(oPC, "Use1 is "+sUsed1);
  SendMessageToPC(oPC, "Use2 is "+sUsed2);
  SendMessageToPC(oPC, "Use3 is "+sUsed3);
  SendMessageToPC(oPC, "Use4 is "+sUsed4);

  if ((nUsed1 == 1) && (nUsed2 == 1) && (nUsed3 == 1) && (nUsed4 == 1))  // Are all levers on?
  {
    AssignCommand(oPC, ActionSpeakString("That should be all of them."));
    object oDoor=GetNearestObjectByTag("VCD_DOOR2");
    SetLocked(oDoor, FALSE);
  }
}

When I pull lever 1, all the numbers read 0. When I pull lever 2; lever 1 reads 1, but lever 2 reads 0. If I then pull lever 1 again; lever 1 reads 0, and lever 2 reads 1. So each lever activates the previous lever pulled at the same time reseting itself to 0. Pulling the same lever twice does nothing.

I got help from the Bioware boards. It seems that you can't use GetNearestObjectByTag() to refer to the object running the script. By just changing them all to GetObjectByTag(), it worked.

[Jamski]

Mine works for me. I've used it in the DoA with you wondering how the door opens Perhaps you mixed up the renaming when you made your four copies?

I see you wanted each lever to have an on-off state. Mine are off until used and then stay used forever. When the fourth one is used, the door opens. Yours is more of a puzzle. I may steal it, if that's ok

Heh, just saw you on the bioware boards
