Making a door open slowly [SOLVED]

[Linus Ågren]

How do you make a door open slowly and not slam up? I've tried with a few PropImpulses but they seem to be quite rough. I looked at the script in the first level where the door opens, and I saw some PropForces but I can't get it to work. So how do you get a door to slowly open?

[Vradcly]

Maby if you send a propforce on a collideable entity like a barrel or something that rolls into the door and by its force in turn makes the door open slowly. And make the barrel invisible by removing its "entity connection". I dont know if this works, just a theory I came up with now...

[Acies]

nah. I've just made one. Add a timer linked to a propimpulse. something like (this is not correct code, just my general idea from memory):

void PushDoorTimer
{
if getlocalvarint("TickX") == 40)
{
return;
}
else
AddPropImpulse("door", 0.0f, 0.0f, 0.04f, "");
// 0.04f (around this force makes it open slowly regarding the timer)
SetSwingDoorDisableAutoClose("door", false);
AddTimer("PushDoor", 0.1f, "PushDoorTimer");
AddLocalVarInt("TickX", 1);
}

This script will give the door a small push every 0.1 second for a total of 4 seconds. The swingdoordisableautoclose is important, since such small forces wouldn't open the door otherwise. If you are still having trouble I could copy --> paste the script for you tomorrow.

Okay, I fixed the errors, but the door won't push itself open.
The script now looks like:

Code: (Select All)

void DoorOpenTimer(string &in asTimer)
{
    if (GetLocalVarInt("TickX") == 40){
        return;
    }
    else
        AddPropImpulse("cellar_wood01_1", 0.0f, 0.0f, 0.04f, "");
        // 0.04f (around this force makes it open slowly regarding the timer)
        SetSwingDoorDisableAutoClose("cellar_wood01_1", false);
        AddTimer("PushDoor", 0.1f, "DoorOpenTimer");
        AddLocalVarInt("TickX", 1);
}

but it doesn't work. The door remains closed.

Add SetSwingDoorClosed("cellar_wood01_1", false); //<- look up the exact function incase I rememeber incorrectly

And then change the order of things to be:

SetSwingDoorDisableAutoClose("cellar_wood01_1", false);
SetSwingDoorClosed("cellar_wood01_1", false);
AddPropImpulse("cellar_wood01_1", 0.0f, 0.0f, 0.04f, "");

Add SetSwingDoorClosed("cellar_wood01_1", false); //<- look up the exact function incase I rememeber incorrectly

And then change the order of things to be:

SetSwingDoorDisableAutoClose("cellar_wood01_1", false);
SetSwingDoorClosed("cellar_wood01_1", false);
AddPropImpulse("cellar_wood01_1", 0.0f, 0.0f, 0.04f, "");

Alright, I changed the script to:

Code: (Select All)

void DoorOpenTimer(string &in asTimer)
{
    if (GetLocalVarInt("TickX") == 40){
        return;
    }
    else
    SetSwingDoorClosed("cellar_wood01_1", false, true);
    SetSwingDoorDisableAutoClose("cellar_wood01_1", false);

    AddPropImpulse("cellar_wood01_1", 0.0f, 0.0f, -0.04f, "");  //I got negative here as my door opens towards me on the Z axis (which gives a lower value when moving the door towards me.
    
    AddTimer("PushDoor", 0.1f, "DoorOpenTimer");
    AddLocalVarInt("TickX", 1);
}

Now the door bugs up and opens/closes very very little, spamming the open & close sound. I tried adding more PropImpulse to the door, but with no luck.

Edit: I found the problem. I changed:

Code: (Select All)

    SetSwingDoorDisableAutoClose("cellar_wood01_1", false);

to:

Code: (Select All)

    SetSwingDoorDisableAutoClose("cellar_wood01_1", true);

Thanks!
