ladder script help

[HoyChampoy]

hey guys. sorry for asking for help all the time but i am to confused on where to start with this. What i want to do is when a player turns a crank, i want it to release a ladder that falls through a ceiling hatch. you might have seen this in amnesia Justine (the part where you pull the lever which kills a guy but releases a ladder down through a hatch.) Any ideas on how to script this? Help would be appreciated! thanks.

One of the ladders in Justine is a MoveObject. MoveObjects can be attached to wheel entities (e.g. cranks) with InteractConnectPropWithMoveObject. Therefore rotating the crank can move the ladder up or down. However, as far as i know, you can't move ladder areas, so you'll have to use SetEntityConnectionStateChangeCallback to (de-)activate the ladder area.

and another question. i got the crank to work with the ladder, but is there a way to have the ladder first start of in the air so the player has to turn the crank in order for the ladder to come down. unfortunately, mine is reversed, which means that its starts off on the ground and goes up into the air when the crank is turned.

SetMoveObjectState
SetEntityActive

[HoyChampoy]

SetMoveObjectState
SetEntityActive

would i put these in the void onstart? is there another code i need? because how will the setmoveobject state know how to make the area active?

SetMoveObjectState(string& asName, float afState);

SetEntityActive(string& asName, bool abActive);

You said you wanted to know how to set the ladder (MoveObject) in the opposite state; i provided you with the function required. You said you wanted to know what function to use to deactivate an area; i provided you with the function required (though deactivating the area can be done in the level editor, too). Neither of these functions "know" when to make the ladder area active or not. I've already provided you with a function to set a callback for informing your script of state changes.

my mistake . What i wanted was, if the ladder was high in the air, i wanted the ladder area unactive (so the player couldn't climb it yet. but when the player turned the crank which causes the ladder to come down, i want the ladder area to be active. I already know how to simply deactivate an area, i just want to know how to deactivate it when the crank is at a specific state.

That's what SetEntityConnectionStateChangeCallback is for.

[HoyChampoy]

I know that already, its just i don't know how to use it or how it works. the code looks like this
SetEntityConnectionStateChangeCallback(string& asName, string& asCallback);

For the string asName do I put the name of the ladder or the name of the valve? and lets say for the asCallback, if i named it activateladderarea, would i put SetEntityActive in there? like this:

SetEntityConnectionStateChangeCallback(string &in asName, string &in asCallback);

void activateladderarea(string &in asEntity, int alState)
{
SetEntityActive("LadderArea_1", true);
}

Name of the valve.

and lets say for the asCallback, if i named it activateladderarea, would i put SetEntityActive in there?

Yes.

like this:

You need to make use of alState if you want to make the ladder area active only when the valve is fully turned towards a certain direction.
